智能图书馆管理系统开发实战系列（五）：koffi调用与接口设计

欢迎大家来到IT世界,在知识的湖畔探索吧!

前言

在前面的文章中，我们分别完成了前端React应用和后端C++ DLL的开发。本文将详细介绍如何通过koffi库实现JavaScript与C++的无缝集成，这是整个系统最关键的技术环节。我们将深入探讨数据类型转换、错误处理、性能优化等核心实践。

koffi技术方案概述

为什么选择koffi？

koffi是一个现代化的Node.js原生库调用方案，相比传统的node-ffi具有以下优势：

1. 性能更优: 基于最新的V8 API，调用开销更小
2. 类型安全: 更好的TypeScript支持和类型检查
3. 内存管理: 自动的内存管理，减少内存泄漏风险
4. 现代API: 支持Promise、async/await等现代异步模式
5. 跨平台: 支持Windows、Linux、macOS等多平台

技术架构设计

我们的前后端集成采用三层架构：

Frontend (React/TypeScript) ↓ (IPC) Electron Main Process (koffi) ↓ (FFI) C++ DLL (Business Logic) 

欢迎大家来到IT世界,在知识的湖畔探索吧!

数据流向：

1. React组件调用useBackendAPI Hook
2. 通过Electron IPC发送请求到主进程
3. 主进程使用koffi调用C++ DLL函数
4. C++ DLL处理业务逻辑并返回JSON结果
5. 结果通过相同路径返回到React组件

koffi集成实现

1. 主进程koffi配置

在
code/frontend/electron/main.ts 中配置koffi：

欢迎大家来到IT世界,在知识的湖畔探索吧!import { koffi } from 'koffi'; import path from 'path'; interface BackendLibrary { InitLibrary: (configJson: string) => boolean; ShutdownLibrary: () => void; AddBook: (bookJson: string, resultJson: koffi.Buffer, resultSize: number) => boolean; DeleteBook: (bookId: string, resultJson: koffi.Buffer, resultSize: number) => boolean; EditBook: (bookJson: string, resultJson: koffi.Buffer, resultSize: number) => boolean; GetBookList: (queryJson: string, resultJson: koffi.Buffer, resultSize: number) => boolean; BorrowBook: (requestJson: string, resultJson: koffi.Buffer, resultSize: number) => boolean; ReturnBook: (requestJson: string, resultJson: koffi.Buffer, resultSize: number) => boolean; GetDashboardStats: (resultJson: koffi.Buffer, resultSize: number) => boolean; } class BackendManager { private static instance: BackendManager; private library: BackendLibrary | null = null; private initialized = false; public static getInstance(): BackendManager { if (!BackendManager.instance) { BackendManager.instance = new BackendManager(); } return BackendManager.instance; } public initialize(): boolean { try { // 确定DLL路径 const dllPath = this.getDllPath(); // 加载DLL const lib = koffi.load(dllPath); // 定义函数接口 this.library = { InitLibrary: lib.func('InitLibrary', 'bool', ['string']), ShutdownLibrary: lib.func('ShutdownLibrary', 'void', []), // 图书管理接口 AddBook: lib.func('AddBook', 'bool', ['string', 'char *', 'int']), DeleteBook: lib.func('DeleteBook', 'bool', ['string', 'char *', 'int']), EditBook: lib.func('EditBook', 'bool', ['string', 'char *', 'int']), GetBookList: lib.func('GetBookList', 'bool', ['string', 'char *', 'int']), // 借阅管理接口 BorrowBook: lib.func('BorrowBook', 'bool', ['string', 'char *', 'int']), ReturnBook: lib.func('ReturnBook', 'bool', ['string', 'char *', 'int']), // 仪表板接口 GetDashboardStats: lib.func('GetDashboardStats', 'bool', ['char *', 'int']) }; // 初始化C++库 const config = { dbPath: path.join(app.getPath('userData'), 'library.db'), logPath: path.join(app.getPath('userData'), 'logs'), maxCacheSize: 1000, enableDebugLog: process.env.NODE_ENV === 'development' }; const success = this.library.InitLibrary(JSON.stringify(config)); if (success) { this.initialized = true; console.log('Backend library initialized successfully'); } return success; } catch (error) { console.error('Failed to initialize backend library:', error); return false; } } private getDllPath(): string { const isDev = process.env.NODE_ENV === 'development'; const basePath = isDev ? path.join(__dirname, '../../dll') : path.join(process.resourcesPath, 'dll'); const dllName = process.platform === 'win32' ? 'libBackend.dll' : process.platform === 'darwin' ? 'libBackend.dylib' : 'libBackend.so'; return path.join(basePath, dllName); } public async callFunction<T = any>( functionName: keyof BackendLibrary, params?: any ): Promise<{ success: boolean; data?: T; error?: string }> { if (!this.initialized || !this.library) { throw new Error('Backend library not initialized'); } return new Promise((resolve) => { try { const resultBuffer = Buffer.alloc(8192); // 8KB缓冲区 let success = false; // 根据函数类型调用不同的接口 switch (functionName) { case 'GetDashboardStats': success = this.library.GetDashboardStats(resultBuffer, resultBuffer.length); break; case 'AddBook': case 'EditBook': success = this.library[functionName]( JSON.stringify(params), resultBuffer, resultBuffer.length ); break; case 'DeleteBook': success = this.library.DeleteBook( params.id, resultBuffer, resultBuffer.length ); break; case 'GetBookList': success = this.library.GetBookList( JSON.stringify(params || {}), resultBuffer, resultBuffer.length ); break; case 'BorrowBook': case 'ReturnBook': success = this.library[functionName]( JSON.stringify(params), resultBuffer, resultBuffer.length ); break; default: resolve({ success: false, error: 'Unknown function' }); return; } if (success) { // 解析返回的JSON数据 const resultStr = resultBuffer.toString('utf8').replace(/\0.*$/g, ''); try { const result = JSON.parse(resultStr); resolve({ success: true, data: result }); } catch (parseError) { resolve({ success: false, error: 'Failed to parse result JSON' }); } } else { resolve({ success: false, error: 'Backend function call failed' }); } } catch (error) { resolve({ success: false, error: error instanceof Error ? error.message : 'Unknown error' }); } }); } public shutdown(): void { if (this.initialized && this.library) { this.library.ShutdownLibrary(); this.initialized = false; console.log('Backend library shutdown'); } } } export { BackendManager }; 

2. IPC通信层

实际项目中的IPC处理器通过 DllBridge 类实现：

// electron/main.ts 中的主进程配置 import { app, BrowserWindow, ipcMain } from 'electron' import path from 'node:path' import { DllBridge } from './dllBridge' app.whenReady().then(() => { // 初始化 DLL 桥接器 DllBridge.getInstance(); createWindow() }) // electron/dllBridge.ts 中的IPC处理 import { ipcMain } from 'electron'; import libGlobalDll from '../src/utils/libGlobalDll'; import dllManager from '../src/utils/dllManager'; export class DllBridge { private static instance: DllBridge; private constructor() { this.setupIpcHandlers(); } private setupIpcHandlers() { const bookManager = dllManager.getBookManager(); const readerManager = dllManager.getReaderManager(); // 图书管理相关IPC处理器 ipcMain.handle('dll:getBookList', async (event, jsonInput: string) => { return await bookManager.getBookList(jsonInput); }); ipcMain.handle('dll:addBook', async (event, jsonInput: string) => { return bookManager.addBook(jsonInput); }); ipcMain.handle('dll:editBook', async (event, jsonInput: string) => { return bookManager.editBook(jsonInput); }); ipcMain.handle('dll:deleteBook', async (event, jsonInput: string) => { return bookManager.deleteBook(jsonInput); }); // 读者管理相关IPC处理器 ipcMain.handle('dll:getReaderList', async (event, jsonInput: string) => { return await readerManager.getReaderList(jsonInput); }); ipcMain.handle('dll:registerReader', async (event, jsonInput: string) => { return readerManager.registerReader(jsonInput); }); } } 

3. 前端API封装

在
code/frontend/src/hooks/useBackendAPI.ts 中封装API调用：

欢迎大家来到IT世界,在知识的湖畔探索吧!import { useCallback, useRef } from 'react'; interface BackendResponse<T = any> { success: boolean; data?: T; error?: string; } // 类型定义 interface Book { id: string; title: string; author: string; isbn: string; category: string; status: 'available' | 'borrowed' | 'reserved' | 'maintenance'; publishDate: string; addedDate: string; } interface BorrowRequest { bookId: string; userId: string; } interface DashboardStats { totalBooks: number; availableBooks: number; borrowedBooks: number; totalUsers: number; activeUsers: number; activeBorrows: number; overdueBooks: number; todayBorrows: number; todayReturns: number; borrowTrend: Array<{ date: string; count: number }>; categoryDistribution: Array<{ category: string; count: number }>; } export const useBackendAPI = () => { const requestIdRef = useRef(0); const callBackend = useCallback(async <T = any>( channel: string, params?: any ): Promise<T> => { const requestId = ++requestIdRef.current; const jsonInput = JSON.stringify(params || {}); console.log(`[API Request ${requestId}] ${channel}:`, jsonInput); try { const startTime = performance.now(); const result = await window.electronAPI.invoke(channel, jsonInput); const endTime = performance.now(); console.log(`[API Response ${requestId}] ${channel} (${(endTime - startTime).toFixed(2)}ms):`, result); return result; } catch (error) { console.error(`[API Error ${requestId}] ${channel}:`, error); throw error; } }, []); // 图书管理API const bookAPI = { addBook: useCallback(async (book: Omit<Book, 'id' | 'addedDate'>): Promise<any> => { return await callBackend('dll:addBook', book); }, [callBackend]), getBookList: useCallback(async (query?: { keyword?: string; category?: string; status?: string; page?: number; pageSize?: number; }): Promise<any> => { return await callBackend('dll:getBookList', query); }, [callBackend]), editBook: useCallback(async (book: Partial<Book>): Promise<any> => { return await callBackend('dll:editBook', book); }, [callBackend]), deleteBook: useCallback(async (bookId: string): Promise<any> => { return await callBackend('dll:deleteBook', { bookId }); }, [callBackend]) }; // 读者管理API const readerAPI = { getReaderList: useCallback(async (query?: any): Promise<any> => { return await callBackend('dll:getReaderList', query); }, [callBackend]), registerReader: useCallback(async (reader: any): Promise<any> => { return await callBackend('dll:registerReader', reader); }, [callBackend]), editReader: useCallback(async (reader: any): Promise<any> => { return await callBackend('dll:editReader', reader); }, [callBackend]), deleteReader: useCallback(async (readerId: string): Promise<any> => { return await callBackend('dll:deleteReader', { readerId }); }, [callBackend]) }; // 状态检查API const statusAPI = { checkStatus: useCallback(async (): Promise<any> => { return await callBackend('dll:checkStatus'); }, [callBackend]), initAllModules: useCallback(async (): Promise<any> => { return await callBackend('dll:initAllModules'); }, [callBackend]), testAllModules: useCallback(async (): Promise<any> => { return await callBackend('dll:testAllModules'); }, [callBackend]) }; return { book: bookAPI, reader: readerAPI, status: statusAPI }; }; // Hook使用示例 export const useBooks = () => { const { book } = useBackendAPI(); return { addBook: book.addBook, getBookList: book.getBookList, editBook: book.editBook, deleteBook: book.deleteBook }; }; export const useReaders = () => { const { reader } = useBackendAPI(); return { getReaderList: reader.getReaderList, registerReader: reader.registerReader, editReader: reader.editReader, deleteReader: reader.deleteReader }; }; export const useStatus = () => { const { status } = useBackendAPI(); return { checkStatus: status.checkStatus, initAllModules: status.initAllModules, testAllModules: status.testAllModules }; }; 

数据类型转换与验证

1. TypeScript类型定义

// src/types/api.ts export interface APIResponse<T = any> { success: boolean; data?: T; error?: string; } export interface PaginatedResponse<T> { items: T[]; total: number; page: number; pageSize: number; totalPages: number; } export interface BookQueryParams { keyword?: string; category?: string; status?: BookStatus; author?: string; publishYear?: number; page?: number; pageSize?: number; sortBy?: 'title' | 'author' | 'publishDate' | 'addedDate'; sortOrder?: 'asc' | 'desc'; } export interface BookCreateRequest { title: string; author: string; isbn: string; category: string; publisher: string; publishDate: string; description?: string; coverUrl?: string; } export interface BorrowBookRequest { bookId: string; userId: string; duration?: number; // 借阅天数，默认30天 } 

2. 数据验证工具

欢迎大家来到IT世界,在知识的湖畔探索吧!// src/utils/validation.ts import { z } from 'zod'; // 图书数据验证模式 export const BookSchema = z.object({ title: z.string().min(1, '书名不能为空').max(200, '书名过长'), author: z.string().min(1, '作者不能为空').max(100, '作者名过长'), isbn: z.string().regex(/^(?:\d{9}[\dX]|\d{13})$/, 'ISBN格式不正确'), category: z.string().min(1, '分类不能为空'), publisher: z.string().min(1, '出版社不能为空'), publishDate: z.string().regex(/^\d{4}-\d{2}-\d{2}$/, '日期格式不正确'), description: z.string().optional(), coverUrl: z.string().url('封面URL格式不正确').optional() }); // 借阅请求验证 export const BorrowRequestSchema = z.object({ bookId: z.string().min(1, '图书ID不能为空'), userId: z.string().min(1, '用户ID不能为空'), duration: z.number().min(1).max(90).optional() }); // 验证函数 export const validateBookData = (data: any): { valid: boolean; errors?: string[] } => { try { BookSchema.parse(data); return { valid: true }; } catch (error) { if (error instanceof z.ZodError) { return { valid: false, errors: error.errors.map(err => err.message) }; } return { valid: false, errors: ['验证失败'] }; } }; export const validateBorrowRequest = (data: any): { valid: boolean; errors?: string[] } => { try { BorrowRequestSchema.parse(data); return { valid: true }; } catch (error) { if (error instanceof z.ZodError) { return { valid: false, errors: error.errors.map(err => err.message) }; } return { valid: false, errors: ['验证失败'] }; } }; 

错误处理机制

1. 统一错误处理

// src/utils/errorHandling.ts export enum APIErrorCode { NETWORK_ERROR = 'NETWORK_ERROR', VALIDATION_ERROR = 'VALIDATION_ERROR', BACKEND_ERROR = 'BACKEND_ERROR', PERMISSION_ERROR = 'PERMISSION_ERROR', NOT_FOUND = 'NOT_FOUND', CONFLICT = 'CONFLICT' } export interface APIError { code: APIErrorCode; message: string; details?: any; } export class APIErrorHandler { static handleError(error: any): APIError { console.error('API Error:', error); // 网络错误 if (error.name === 'TypeError' && error.message.includes('fetch')) { return { code: APIErrorCode.NETWORK_ERROR, message: '网络连接失败，请检查网络状态' }; } // 后端返回的错误 if (error.response) { const { status, data } = error.response; switch (status) { case 400: return { code: APIErrorCode.VALIDATION_ERROR, message: data.message || '请求参数错误' }; case 403: return { code: APIErrorCode.PERMISSION_ERROR, message: '权限不足' }; case 404: return { code: APIErrorCode.NOT_FOUND, message: '资源不存在' }; case 409: return { code: APIErrorCode.CONFLICT, message: '数据冲突，请刷新后重试' }; default: return { code: APIErrorCode.BACKEND_ERROR, message: data.message || '服务器内部错误' }; } } // 默认错误 return { code: APIErrorCode.BACKEND_ERROR, message: error.message || '未知错误' }; } static createErrorMessage(error: APIError): string { switch (error.code) { case APIErrorCode.NETWORK_ERROR: return '网络连接失败，请检查网络状态后重试'; case APIErrorCode.VALIDATION_ERROR: return `数据验证失败：${error.message}`; case APIErrorCode.PERMISSION_ERROR: return '您没有执行此操作的权限'; case APIErrorCode.NOT_FOUND: return '请求的资源不存在'; case APIErrorCode.CONFLICT: return '操作冲突，请刷新页面后重试'; default: return error.message || '操作失败，请稍后重试'; } } } 

2. React错误边界

欢迎大家来到IT世界,在知识的湖畔探索吧!// src/components/ErrorBoundary.tsx import React, { Component, ReactNode } from 'react'; import { APIErrorHandler, APIError } from '../utils/errorHandling'; interface ErrorBoundaryState { hasError: boolean; error?: APIError; } interface ErrorBoundaryProps { children: ReactNode; fallback?: (error: APIError) => ReactNode; } export class ErrorBoundary extends Component<ErrorBoundaryProps, ErrorBoundaryState> { constructor(props: ErrorBoundaryProps) { super(props); this.state = { hasError: false }; } static getDerivedStateFromError(error: Error): ErrorBoundaryState { const apiError = APIErrorHandler.handleError(error); return { hasError: true, error: apiError }; } componentDidCatch(error: Error, errorInfo: React.ErrorInfo) { console.error('Error Boundary caught an error:', error, errorInfo); } render() { if (this.state.hasError && this.state.error) { if (this.props.fallback) { return this.props.fallback(this.state.error); } return ( <div className="flex flex-col items-center justify-center h-64 p-8"> <div className="text-red-500 text-6xl mb-4"> <i className="fas fa-exclamation-triangle"></i> </div> <h2 className="text-xl font-semibold text-gray-800 mb-2"> 出现错误 </h2> <p className="text-gray-600 text-center mb-4"> {APIErrorHandler.createErrorMessage(this.state.error)} </p> <button onClick={() => this.setState({ hasError: false, error: undefined })} className="px-4 py-2 bg-blue-500 text-white rounded hover:bg-blue-600" > 重试 </button> </div> ); } return this.props.children; } } 

性能优化策略

1. 缓存机制

// src/hooks/useCache.ts import { useRef, useCallback } from 'react'; interface CacheEntry<T> { data: T; timestamp: number; expiry: number; } export const useCache = <T = any>(defaultExpiry: number = 5 * 60 * 1000) => { const cache = useRef<Map<string, CacheEntry<T>>>(new Map()); const get = useCallback((key: string): T | null => { const entry = cache.current.get(key); if (!entry) return null; const now = Date.now(); if (now > entry.timestamp + entry.expiry) { cache.current.delete(key); return null; } return entry.data; }, []); const set = useCallback((key: string, data: T, expiry?: number): void => { cache.current.set(key, { data, timestamp: Date.now(), expiry: expiry || defaultExpiry }); }, [defaultExpiry]); const clear = useCallback((pattern?: string): void => { if (pattern) { const regex = new RegExp(pattern); for (const key of cache.current.keys()) { if (regex.test(key)) { cache.current.delete(key); } } } else { cache.current.clear(); } }, []); const has = useCallback((key: string): boolean => { return get(key) !== null; }, [get]); return { get, set, clear, has }; }; // 使用缓存的API Hook export const useCachedBookList = () => { const { book } = useBackendAPI(); const cache = useCache<{ books: Book[]; total: number }>(); const getBookList = useCallback(async (query?: BookQueryParams) => { const cacheKey = `books:${JSON.stringify(query || {})}`; // 尝试从缓存获取 const cached = cache.get(cacheKey); if (cached) { return cached; } // 从后端获取 const result = await book.getBookList(query); // 缓存结果 cache.set(cacheKey, result, 2 * 60 * 1000); // 2分钟缓存 return result; }, [book, cache]); const invalidateCache = useCallback((pattern?: string) => { cache.clear(pattern || 'books:'); }, [cache]); return { getBookList, invalidateCache }; }; 

2. 请求队列管理

欢迎大家来到IT世界,在知识的湖畔探索吧!// src/utils/requestQueue.ts interface QueuedRequest { id: string; promise: Promise<any>; timestamp: number; } class RequestQueue { private queue: Map<string, QueuedRequest> = new Map(); private maxConcurrent: number = 5; private currentCount: number = 0; async enqueue<T>(key: string, requestFn: () => Promise<T>): Promise<T> { // 如果已经有相同的请求在进行，返回现有的Promise const existing = this.queue.get(key); if (existing) { return existing.promise; } // 等待队列有空位 while (this.currentCount >= this.maxConcurrent) { await new Promise(resolve => setTimeout(resolve, 10)); } this.currentCount++; const promise = requestFn() .finally(() => { this.queue.delete(key); this.currentCount--; }); const request: QueuedRequest = { id: key, promise, timestamp: Date.now() }; this.queue.set(key, request); return promise; } clear(): void { this.queue.clear(); this.currentCount = 0; } getQueueSize(): number { return this.queue.size; } } export const requestQueue = new RequestQueue(); // 使用请求队列的Hook export const useQueuedRequest = () => { const { book } = useBackendAPI(); const queuedGetBookList = useCallback(async (query?: BookQueryParams) => { const key = `getBookList:${JSON.stringify(query || {})}`; return requestQueue.enqueue(key, () => book.getBookList(query)); }, [book]); return { queuedGetBookList }; }; 

3. 内存泄漏防护

// src/hooks/useAbortableRequest.ts import { useRef, useEffect, useCallback } from 'react'; export const useAbortableRequest = () => { const abortControllersRef = useRef<Set<AbortController>>(new Set()); const createRequest = useCallback(<T>( requestFn: (signal: AbortSignal) => Promise<T> ): Promise<T> => { const controller = new AbortController(); abortControllersRef.current.add(controller); return requestFn(controller.signal) .finally(() => { abortControllersRef.current.delete(controller); }); }, []); const abortAll = useCallback(() => { abortControllersRef.current.forEach(controller => { controller.abort(); }); abortControllersRef.current.clear(); }, []); // 组件卸载时取消所有请求 useEffect(() => { return () => { abortAll(); }; }, [abortAll]); return { createRequest, abortAll }; }; // 带取消功能的API Hook export const useAbortableBookAPI = () => { const { book } = useBackendAPI(); const { createRequest } = useAbortableRequest(); const getBookList = useCallback(async (query?: BookQueryParams) => { return createRequest(async (signal) => { // 这里需要在底层API中支持AbortSignal return book.getBookList(query); }); }, [book, createRequest]); return { getBookList }; }; 

调试与监控

1. 性能监控

欢迎大家来到IT世界,在知识的湖畔探索吧!// src/utils/performance.ts class PerformanceMonitor { private metrics: Map<string, number[]> = new Map(); startTiming(operation: string): () => void { const startTime = performance.now(); return () => { const endTime = performance.now(); const duration = endTime - startTime; if (!this.metrics.has(operation)) { this.metrics.set(operation, []); } this.metrics.get(operation)!.push(duration); // 只保留最近100次记录 const records = this.metrics.get(operation)!; if (records.length > 100) { records.shift(); } console.log(`[Performance] ${operation}: ${duration.toFixed(2)}ms`); }; } getAverageTime(operation: string): number { const records = this.metrics.get(operation); if (!records || records.length === 0) return 0; const sum = records.reduce((a, b) => a + b, 0); return sum / records.length; } getMetrics(): Record<string, { average: number; count: number }> { const result: Record<string, { average: number; count: number }> = {}; for (const [operation, records] of this.metrics) { result[operation] = { average: this.getAverageTime(operation), count: records.length }; } return result; } } export const performanceMonitor = new PerformanceMonitor(); // 使用性能监控的Hook export const useMonitoredBackendAPI = () => { const { book, loan, dashboard } = useBackendAPI(); const monitoredBook = { getBookList: useCallback(async (query?: BookQueryParams) => { const endTiming = performanceMonitor.startTiming('getBookList'); try { return await book.getBookList(query); } finally { endTiming(); } }, [book]), addBook: useCallback(async (bookData: any) => { const endTiming = performanceMonitor.startTiming('addBook'); try { return await book.addBook(bookData); } finally { endTiming(); } }, [book]) }; return { book: monitoredBook, loan, dashboard }; }; 

2. 错误上报

// src/utils/errorReporting.ts interface ErrorReport { timestamp: string; error: string; stack?: string; userAgent: string; url: string; userId?: string; additionalInfo?: any; } class ErrorReporter { private reports: ErrorReport[] = []; private maxReports = 50; reportError(error: Error, additionalInfo?: any): void { const report: ErrorReport = { timestamp: new Date().toISOString(), error: error.message, stack: error.stack, userAgent: navigator.userAgent, url: window.location.href, additionalInfo }; this.reports.push(report); // 限制报告数量 if (this.reports.length > this.maxReports) { this.reports.shift(); } // 在开发环境下输出详细错误信息 if (process.env.NODE_ENV === 'development') { console.error('Error Report:', report); } } getReports(): ErrorReport[] { return [...this.reports]; } clearReports(): void { this.reports = []; } exportReports(): string { return JSON.stringify(this.reports, null, 2); } } export const errorReporter = new ErrorReporter(); // 全局错误处理 window.addEventListener('error', (event) => { errorReporter.reportError(event.error, { filename: event.filename, lineno: event.lineno, colno: event.colno }); }); window.addEventListener('unhandledrejection', (event) => { const error = event.reason instanceof Error ? event.reason : new Error(String(event.reason)); errorReporter.reportError(error, { type: 'unhandledRejection' }); });
