Question

我正在制作一个web应用程序，后端使用django，前端使用Angular，我正在使用django TokenAuthentication进行身份验证，当我使用POSTMAN或REST框架接口测试请求时，一切正常，但当我尝试使用Angular制作POST时，我遇到下一个错误：

 Exception happened during processing of request from ('127.0.0.1', 62030)

Django代码：

你知道吗视图.py地址：

from rest_framework.authentication import TokenAuthentication

class LoginViewSet(viewsets.ViewSet):

    serializer_class = AuthTokenSerializer

    def create(self, request):
        return ObtainAuthToken().post(request)

角度代码：

export class LoginService {

  httpHeaders = new HttpHeaders({'Content-Type': 'application/json'});

  baseUrl = environment.Server_url;

  constructor(private http: HttpClient) {}

  login(nameUser, passwordUser): Observable <any> {
    const body = {username: nameUser , password: passwordUser};
    for(var i = 0; i < 50; i++){
      this.http.post(this.baseUrl + '/usersActions/login/', body , {headers: this.httpHeaders});
    }
    return this.http.post(this.baseUrl + '/usersActions/login/', body , {headers: this.httpHeaders});
  }
