我创建了一个实现httpinterceptor的角度拦截器.它适用于http GET请求.但是没有POST请求.

我的拦截器代码如下.

import { Injectable, Injector } from '@angular/core';
import { HttpEvent, HttpInterceptor, HttpHandler, HttpRequest,         HttpHeaders,HttpResponse } from '@angular/common/http';

import { Observable } from 'rxjs';

@Injectable()
export class MyHttpInterceptor implements HttpInterceptor {
  constructor() { console.log('enter constructor');
   }

  intercept(
    req: HttpRequest<any>,
    next: HttpHandler
  ): Observable<HttpEvent<any>> {
    console.log('entered interceptor')
    const token = localStorage.getItem('sessiontoken') != null ?     localStorage.getItem('sessiontoken') : 'notoken';
    const authReq = req.clone({ headers:     req.headers.set("Authorization", token) });

    return next.handle(authReq);

  }

}

该模块添加了提供程序.

providers: [
{
  provide: HTTP_INTERCEPTORS,
  useValue: { disableClose: true, …
