未在 Angular 8 的 Post API 调用中发送授权承载令牌

Question

EDIT 2: I forgot to return when I updated the code...facepalm

EDIT:

(After changing post call to:

this._http.post<userArray>(this.apiUrl,users$, httpOptions);

Now it's giving me this in Console log..any fix? thanks: https://ibb.co/6PLK71j )

I'm using postman for my rest API.

Authorization Token is not being sent for POST call but same Authorization Token and HTTP header is working fine for DELETE call.

My API: http://dradiobeats.x10host.com/api/areas

(collection for Postman: https://www.getpostman.com/collections/deb24ed6036451580238 )

Authorization Token: Postman Authorization: Bearer Token.

Console Log:

Console Log

No Authorization Header is passed

Can someone help me with this? Thanks. c:

Answer 1

Use this._http.post<userArray>(this.apiUrl, data , httpOptions);

Second parameter is the data you needs to pass

Answer 2

Use a angular interceptor to add the token to every request.

import { Injectable } from '@angular/core';

import {
  HttpEvent,
  HttpInterceptor,
  HttpHandler,
  HttpRequest,
  HttpResponse
} from '@angular/common/http'
import { Observable } from 'rxjs';
import { tap } from 'rxjs/operators';


@Injectable()

export class ApiHeaderInterceptor implements HttpInterceptor {

  constructor() { }

  // intercept request and add token
  intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {

    const bearer = 'Bearer eyJ0eXAiOiJKV1QiLCJh.....'; // this.anyService.getToken();

    if (bearer) {
      request = request.clone({
        setHeaders: {
          'Authorization': bearer,
        }
      });
    }

    return next.handle(request)
      .pipe(
        tap(event => {
          if (event instanceof HttpResponse) {
          }
        }, error => {
          // Hadle Errors
        })
      );

  };
}

Add it to your app.module providers like so

providers: [
    { provide: HTTP_INTERCEPTORS, useClass: ApiHeaderInterceptor, multi: true },
],

Answer 3

I think your post request should be like

this._http.post<userArray>(this.apiUrl,users$, httpOptions);

You are passing httpOptions as a second parameter but it should be the third parameter for post request. Second parameter should be the body.

like this

post(url: string, body: any, options:....

Refer their DOC for more details

Also in component you are calling onSubmit method of service by passing a single user but service expecting array of users. So you have to change the service onSubmit method signature like bellow. So I it will expecting a single user too.

 onSubmit(users$: userArray)

Answer 4

您的请求正文在 onSubmit() 后调用中丢失。

this._http.post(<url>, <request body>, <headers>);

Answer 5

Try this: this._http.post<userArray>(this.apiUrl, requestData , httpOptions);

Second parameter in the post is a request object without object you can't send post request
