Laravel 5.4护照：unsupported_grant_type

你好，我尝试做一个web应用程序，我有一个问题。当请求从/的OAuth /令牌令牌我接收此响应：Laravel 5.4护照：unsupported_grant_type

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

而我的代码是：

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); 
     }); 
    } 
}

而请求头：

你安装了一个'密码'客户端吗？ –

我不这么认为，我如何安装？ –

您需要为Passport安装password客户端。假设你已经安装并配置了护照，生成密码的客户端，运行：

php artisan passport:client --password

确保在您的API请求使用该命令的输出细节。

这是一样的..我应该改变一些东西？ –

像在客户端编辑user_id一样？ –

确保'client_id'和'client_secret'匹配您刚刚运行的命令生成的一个。 –
