Question

您好我尝试做一个Web应用程序，但我遇到了问题。当我从/ oauth / token请求令牌时，我收到了这个回复：

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

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); 
        });
    }
}

我没有任何其他细节。

Answer 1

您需要为Passport安装password客户端。假设您已安装并配置了Passport，要生成密码客户端，请运行：

php artisan passport:client --password

确保在API请求中使用此命令输出中的详细信息。

Answer 2

我在Fiddler上使用了以下请求，效果很好：

Answer 3

在邮递员中使用的表单数据如下

grant_type : password

client_id  :  2

client_secret : vSFxVqALQHjyotPyGfhrGj3ziudUGsts2ZWiAGms or whatever this is 

username: myemail@yahoo.com 

password: mypassword

scope:

如果那里没有数据，则可以使用以下命令创建客户端，从而从oauth_clients表中获取客户端ID和密码

php artisan passport:client --password

使用oauth_clients表的特定行，其中密码客户端列的值为1
看看我如何将令牌生成代码与登录集成在一起。我使用正确的格式来解决laravel 5.8中的拨款问题

public function login(Request $request) {
    if (Auth::attempt(['email' => request('email'), 'password' => request('password')])) {
        $user = Auth::user();

         if(Auth::check()) {  // check whether user exist
           $req = Request::create('/oauth/token', 'POST',[
                     'grant_type' => 'password',
                     'client_id' => 2,
                     'client_secret' => 'WDv6wrY9Tf9HuixaiQjDWGy7yBqEG1IrmsLucAUI',
                     'username' => request('email'),
                     'password' => request('password'),
                     'scope' => '' 
                   ]);   
                   $res = app()->handle($req);
                   $responseBody = json_decode($res->getContent()); // convert to json object
           return response()->json(['success' => $responseBody], $res->getStatusCode());

         } else {
            return response()->json(['error' => 'Not logged in '], 401);
          }

    } else {
        return response()->json(['error' => 'Authentication failed '], 401);
    }
}
