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...
//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(...
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...
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'; ...
### 摘要 本文介绍了Angular框架中优秀的`@angular/common/http`模块的移植与应用。该模块提供了响应式的AJAX功能,极大地提升了开发者处理HTTP请求的能力。通过深入探讨这一特性,本文旨在帮助所有Angular用户更好地理解和利用这一强大工具。 ### 关键词 Angular, HTTP, AJAX, 移植, 响应式 ## 一、Angular HTTP ...
● 前端请求时header中携带token,Angular中需要实现HttpInterceptor接口并重写intercept方法: export class AuthInterceptor implements HttpInterceptor { intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> { // 添加token
