Question

我想使用post将角度6的单个字符串传递给springboot服务器控制器，但是它始终会因httpErrorResponse 403而失败，并且错误消息“禁止”，我是角度不熟悉的，希望有人可以帮助我，非常感谢。我的Java版本是10。以下是我的相关代码：

component.html：

<p-button label="Stop" styleClass="ui-button-danger" (onClick)="send()"></p- 
 button>
{{result}}

component.ts：

export class TestComponent implements OnInit {
  selectedFile: string;
  selectedFile = "20180812";
  result: string;
  constructor(private cityService: CityService) {}

  send() {
  //pass a string  selectedFile
  this.cityService.send(this.selectedFile).subscribe(data=> this.result = 
  data);
  }
}

service.ts：

import { Injectable } from '@angular/core';
import {HttpClient, HttpHeaders} from "@angular/common/http";
import {Observable} from "rxjs/internal/Observable";
@Injectable({
  providedIn: 'root'
})

export class CityService {
  private testUrl = '//localhost:8080/sendString';
  constructor(private http: HttpClient) { }

  send(s: string): Observable<any> {
      return this.http.post(this.testUrl, s, {
          headers: new HttpHeaders({
            'Content-Type': 'text/plain'
          })
      });
   }
  }

controller.java：

@CrossOrigin(origins = "http://localhost:4200")
@RestController
public class TestController {

@RequestMapping(value = "/sendString", method = RequestMethod.POST,consumes = 
                "text/plain")
public String pass(@RequestBody String test1) {
    System.out.println(test1);
    return test1;
}}

securityConfig.java：

package com.predicine.sbproto.security;

import *;

@Configuration
@EnableGlobalMethodSecurity( securedEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {

}

application.property：

#Security Configuration
spring.security.user.name=user
spring.security.user.password=user
spring.security.user.roles=USER

如何从angular 6发送一个字符串到springboot rest控制器？
