要使用Angular将客户端的产品ID添加到服务器,首先需要创建一个Angular应用,然后创建一个服务来处理与服务器的通信,最后创建一个组件来触发服务中的方法。以下步骤详细说明:
app.module.ts
中配置HttpClientModule
和HttpInterceptor
: import { NgModule } from '@angular/core'; import { BrowserModule } from '@angular/platform-browser'; import { HttpClientModule } from '@angular/common/http'; import { AppInterceptor } from './app.interceptor'; @NgModule({ imports: [ BrowserModule, HttpClientModule ], providers: [ { provide: HTTP_INTERCEPTORS, useClass: AppInterceptor, multi: true } ], exports: [ BrowserModule, HttpClientModule ], components: [AppComponent] }) app.interceptor.ts
中创建一个拦截器,用于添加HTTP请求头: import { Injectable } from '@angular/core'; import { HttpEvent, HttpInterceptor, HttpHandler, HttpRequest } from '@angular/common/http'; import { Observable } from 'rxjs'; @Injectable() export class AppInterceptor implements HttpInterceptor { constructor() {} intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> { const modifiedReq = req.clone({ } return next.handle(modifiedReq); }ng serve
启动应用,然后访问组件页面,点击添加产品按钮,查看服务器是否接收到了产品ID。 ng serve
