1、创建错误处理的error-handler.service.ts import{HttpClient}from'@angular/common/http';import{ErrorHandler,Injectable}from'@angular/core';@Injectable()exportclassAppGlobalErrorhandlerimplementsErrorHandler{constructor(privatehttp:HttpClient){ }// 当程序中出现异常时,会自动调用 handleError 钩子,可判断是客户...
import { HttpEvent, HttpInterceptor, HttpHandler, HttpRequest } from '@angular/common/http'; import { Observable } from 'rxjs'; export class ExampleInjector implements HttpInterceptor { intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> { return next.handle(req); ...
Global Error Handling: Implement a global error handler service to catch unhandled errors and log or display them to the user. Router Error Handling: Angular's router provides hooks like `resolve` and route guards (`CanActivate`, `CanDeactivate`) to handle routing-related errors. Error Interc...
//统一处理返回信息,如果是错误则在这里统一处理,注意如果这样处理错误(reject),那么所有的错误信息会进入http的error回调,在success里默认就是成功,都可以不判断data.success if (res.data.success == false) { TASApp.ajaxReturnErrorHandler(res.data["info"]); //TASApp是一个constant对象 return $q.reject(...
简单的全局状态管理可以创建一个global.ts,再创建依赖注入,如下 // globals.ts import { Injectable } from '@angular/core'; @Injectable() export class Globals { role: string = 'test'; } 在组件中可以这样调用 // hello.component.ts import { Component } from '@angular/core'; ...

Centralized code for cross-cutting concerns: HTTP Interceptors allow you to define logic for common tasks, such as authentication, logging, error handling, or adding headers, in a centralized location. Global application-level modifications: Interceptors operate globally, intercepting all HTTP requests an...
