在angular 5 app中设置 Headers 中的JWT标记-Java 学习之路

嗨我正在为后端和角度5应用程序作为客户端的django休息框架工作..我需要在服务器的每个请求中发送JWT令牌和Content-Type如何在请求标头中设置“jsonwebtoken”和“content-type”？ ??看起来像RequestOptions和Header在angular 5中被弃用了任何解决方案???

import {Injectable} from '@angular/core';
import {Headers, RequestOptions} from '@angular/http'
import {HttpClient} from "@angular/common/http";
import 'rxjs/add/operator/map'


@Injectable()
export class UserService {

  private options;
  constructor(private http: HttpClient) {
    const token = localStorage.getItem('theuser');

    const headers = new Headers();
    headers.append('Content-Type', 'application/json');
    headers.append('Authorization', 'Bearer' + ' ' + token)
    this.options = new RequestOptions({headers: headers});

    console.log(this.options)
  }


  userInfo() {
    return this.http.get<any>("http://localhost:8000/user-detail/",this.options)

  }

}

您可以扩展http拦截器类 . 使用以下内容创建新服务token.interceptor.ts .

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

import {
  HttpRequest,
  HttpHandler,
  HttpEvent,
  HttpInterceptor
} from '@angular/common/http';
import { Observable } from 'rxjs/Observable';
declare var localStorage : any;

@Injectable()
export class TokenInterceptor implements HttpInterceptor {
  constructor() {}
  intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    let allowedUrls =( request.url.indexOf("dealer/signup") < 0 && request.url.indexOf("dealer/login") < 0 );   

    if(allowedUrls){

        let authToken = localStorage.getItem("dealertoken");
        request = request.clone({
            headers: request.headers.set('Authorization', 'Bearer '+ authToken)
            /* setHeaders: {
                Authorization: 'Bearer '+ authToken
            } */
        });
    }
    return next.handle(request);
  }
}

并在app.module.ts中导入它

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

您传递的第二个参数是选项 . 它包含 headers 属性 . 您可以将标头添加到此属性中 .

如何弃用 - 从 @angular/common/http 导入HttpHeaders .

如果您需要为每个令牌添加JWT，最好使用HttpInterceptor
