Laravel 5.4 Reisepass: unsupported_grant_type

Question

Hallo Ich versuche, eine Webanwendung zu tun, und ich habe ein Problem. Wenn ich das Token aus/oauth/Token anfordern erhalte ich diese Antwort:

{"error":"unsupported_grant_type","message":"The authorization grant type is not supported by the authorization server.","hint":"Check the `grant_type` parameter"} 

Und mein Code:

import { Injectable } from '@angular/core'; 
import { Http, Response, RequestOptions, Headers } from '@angular/http'; 
import { Observable } from 'rxjs/Observable'; 
import 'rxjs/Rx'; 

@Injectable() 
export class UserService { 

    private API: string = 'api/'; 
    private OAuth: string = 'oauth/' 

    constructor(private _HTTP: Http) { } 

    private get_header(): RequestOptions { 
     let headers = new Headers(); 
     headers.append('Access-Control-Allow-Origin', '*'); 
     headers.append('Content-Type', 'application/x-www-form-urlencoded'); 
     return new RequestOptions({ headers: headers }); 
    } 

    Signin(email: string, password: string): void { 

     let data = { 
      form_params: { 
       grant_type: 'password', 
       client_id: 2, 
       client_secret: 'vSFxVqALQHjyotPyGfhrGj3ziudUGsts2ZWiAGms', 
       username: email, 
       password: password, 
       scope: '*', 
      } 
     }; 

     this._HTTP.post(
      this.OAuth + 'token', 
      data, 
      this.get_header() 
     ).toPromise() 
     .then((_response) => { 
      console.log (_response); 
     }); 
    } 
} 

Und der Request-Header:

Answer 1

Sie müssen einen password Client für Passport installieren. Sie haben installiert und konfiguriert Passport Angenommen, ein Passwort-Client zu generieren, auszuführen:

php artisan passport:client --password 

Stellen Sie sicher, die Details aus der Ausgabe dieses Befehls in Ihrer API-Anfragen zu verwenden.
