将用户名和密码传递给Angular6中的REST API

标签: angular angular6

我有两个API并执行以下步骤:

  1. 点击第一个API获取ID和令牌
  2. 使用ID,令牌作为用户名和密码,与请求正文一起点击第二个API
  3. 我已经尝试了太多的选项,所有这些选项似乎都适用于旧版本的角度。

    问题 当我进行第一次api调用(ping)时,它返回ID和令牌。我需要调用另一个api2将其作为用户名和密码传递(我在POSTman中将这些Returened值作为username / passsword)。我尝试设置一些授权标题,但它没有工作,并抛出401

    我已经经历了很多例子,但那些与角度版本不匹配

    我-HTTP-interceptor.ts

    import { Injectable, Injector } from '@angular/core';
    import { HttpEvent, HttpInterceptor, HttpHandler, HttpRequest,HttpHeaders } from '@angular/common/http';
    import { Observable, of } from 'rxjs'; 
    
    @Injectable()
    export class MyHttpInterceptor implements HttpInterceptor {
    constructor() { }
    
    intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    
    console.log("intercepted request ... ");
    
    // Clone the request to add the new header.
    
    const authReq = req.clone({ headers: req.headers.set( 'Authorization', 'Basic dmlld2VyLTFAaXR0aWFtLmNvbTp2aWV3ZXIx')});
    console.log("Sending request with new header    now ...");
    //  console.log(authReq)
    //send the newly created request
    return next.handle(authReq)
    }
    }
    

    App.module.ts

    import { BrowserModule } from '@angular/platform-browser';
    import { NgModule } from '@angular/core';
    import { HttpClientModule, HTTP_INTERCEPTORS } from '@angular/common/http';
    import { MyHttpInterceptor } from './my-http-interceptor'
    import { AppComponent } from './app.component';
    
    @NgModule({
    declarations: [
      AppComponent,
    ],
    imports: [
      BrowserModule,
      HttpClientModule
    ],
    providers: [
    {
      provide: HTTP_INTERCEPTORS,
      useClass: MyHttpInterceptor,
      multi: true
    }
    ],
    bootstrap: [AppComponent]
    })
    

    导出类AppModule {}

    App.compoent.ts

     import { Component } from '@angular/core';
    import { HttpClient,HttpHeaders } from '@angular/common/http';
    import {RequestOptions, Request, RequestMethod,Http,Headers} from '@angular/http';
    @Component({
      selector: 'app-root',
      templateUrl: './app.component.html',
      styleUrls: ['./app.component.css']
    })
    
    export class AppComponent {
    
      constructor(public http: HttpClient) {}
    
      public ping() {
        this.http.get('https://Api1.com')
          .subscribe(  
            data => console.log(data));}
    
       public api2(){
         this.http.get('https://Api2.com')
          .subscribe(  
             data => console.log(data));}
       }
    
    
    
    }
    

    app.component.html

    <button (click)="ping()">Method 1</button>
    <button (click)="api2()">Method 2</button>
