如何在角度4中显示错误请求响应的正文？

Question

To provide login error message I added a message in the constructor of Bad Request Response which shows in the postman while testing an web api. Like this: return BadRequest("Error Message"); Now I want to get that message and display in a component in the client side. But I don't know how to retrieve that. I am trying like this:

signIn() {
this.authService.login(this.loginCredentials).subscribe(result=>{
  if(result){
    let returnUrl=this.route.snapshot.queryParamMap.get('returnUrl');
    this.router.navigate([returnUrl||'/']);
  } 
},
(err) => {
  this.loginMessage=true;
  console.log(err.body);
  this.invalidLogin=true;
});

}

Answer 1

Finally got it. It will be

console.log(err.body);
