相关疑难解决方法(0)

在过去的两天中，我使用Angular 6尝试了许多不同的方法，本文的最新方法是：https : //stackoverflow.com/a/47401544。但是，仍未根据请求设置标头。

import {Inject, Injectable} from '@angular/core';
import {
  HttpEvent,
  HttpInterceptor,
  HttpHandler,
  HttpRequest,
  HttpErrorResponse,
} from '@angular/common/http';
import { Observable } from 'rxjs/Observable';

@Injectable()
export class AuthTokenInterceptor implements HttpInterceptor {
  constructor() {}

  intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    return next.handle(req).do((event: HttpEvent<any>) => {
      if (localStorage.getItem('id_token') != null) {
        // Clone the request to add the new header.
        const request = req.clone({
          setHeaders: {
            'Content-Type' : 'application/json; charset=utf-8',
            'Accept'       : 'application/json',
            'Authorization': `Bearer ${localStorage.getItem('id_token')}`
          }
        });
        return …

这是我的JS代码,(如果我删除标题选项,它可以正常工作).

$http.get(env.apiURL()+'/banks', {
    headers: {
        'Authorization': 'Bearer '+localStorageService.get('access_token')
    }
})

这是请求:

OPTIONS /banks HTTP/1.1
Host: localhost:8080
Connection: keep-alive
Access-Control-Request-Method: GET
Origin: http://localhost:8081
User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/33.0.1750.146 Safari/537.36

Accept: */*
Referer: http://localhost:8081/
Accept-Encoding: gzip,deflate,sdch
Accept-Language: en-US,en;q=0.8,vi;q=0.6

和回应:

HTTP/1.1 404 Not Found
Access-Control-Allow-Headers: Accept, Content-Type, Content-Length, Accept-Encoding, X-CSRF-Token, Authorization
Access-Control-Allow-Methods: POST, GET, OPTIONS, PUT, DELETE
Access-Control-Allow-Origin: http://localhost:8081
Content-Type: text/plain; charset=utf-8
Date: Mon, 17 Mar 2014 11:05:20 GMT
Content-Length: 19

我添加了Accept和Authorization …
