无法从获取请求中获取数据

Question

我正在尝试通过从服务中订阅从api获取数据。但它返回false。

  

service.ts

fetch_userdata(){
var headers = new HttpHeaders().set('Authorization', 'Token ' + 
localStorage.getItem('user_token'));

var options =  {
  headers: headers
};
return this.httpClient.get('api/auth/fetch_users',options)
}

  

component.ts

constructor(private Authentication:AuthService){}

getUsersFromServices():void{

this.Authentication.fetch_userdata().subscribe(
  (data) =>{      
    console.log(data);         
  },err =>{
    console.log('error occured');
  }
)
}

console error
