HttpParams doesn't work in angular getting 502 error

Question

I am using angular 8

• I am getting 502 statu

Answer 1

Tried visiting the api endpoint on browser, check if the URL is correct, and maybe include access control allow origin in your header

Answer 2

Im not sure but please check this......

This Should be your service file code

userlogin(userid, smpassword) {
const params = new HttpParams()
.set('user_id', userid)
.set('sm_password', smpassword);
console.log(params);    
return this.http.post(this.baseUrl+'user/login',JSON.stringify(params)).pipe(map((res) => {
  return res;
}));

}

This Should be your login.component.ts

     login() {
        const email =  this.Userlogin.get('email').value;
        const password = this.Userlogin.get('password').value;
        this.rest.userlogin(email, password).subscribe((result)=> {
        result = JSON.Parse(result)
            console.log(result);
          }
        );
