php - Sage One API - unsupported_grant_type

Question

我正在尝试按照 docs 获取 Sage One API 的访问 token 使用 Guzzle (v6)/Laravel 5.2(Laravel 的参与与本题无关)，卡在“请求访问 token ”阶段。

错误

Client error: `POST https://api.sageone.com/oauth2/token` resulted in a
 `400 Bad Request` response: {"error":"unsupported_grant_type"}

违规代码

    $client = new Client([
        'base_uri'=>'https://api.sageone.com',
        'headers' => ['content_type' => 'application/x-www-form-urlencoded']
    ]);
    $data = [
        'client_id' => getenv('SAGE_CLIENT'),
        'client_secret' => getenv('SAGE_SECRET'),
        'code' => $request->code,
        'grant_type' => 'authorization_code',
        'redirect_uri'=>'https://myurl.com/sage/refresh'
    ];

    $response = $client->request('POST','/oauth2/token',['json' => $data]);

文档声明 “grant_type - 代码相关的授权类型。authorization_code 或 refresh_token。”，我都试过了。其他 var 都很好，只是 grant_type 似乎失败了。

更新 1 调试 header 生成以下输出。

您将值作为 JSON 编码数据进行 POST，但您应该使用表单编码进行 POST。请参阅:http://docs.guzzlephp.org/en/latest/request-options.html#form-params , 所以

$response = $client->request('POST','/oauth2/token',['form_params' => $data]);

编辑:

您应该再次检查您的代码，因为我刚刚验证并仔细检查了此更改是否使其适用于 live sage 环境。我使用的完整代码:

<?php
require 'vendor/autoload.php';

$client = new GuzzleHttp\Client([
        'base_uri'=>'https://api.sageone.com',
        'headers' => ['content_type' => 'application/x-www-form-urlencoded']
    ]);

$data = [
    'client_id' => getenv('SAGE_CLIENT'),
    'client_secret' => getenv('SAGE_SECRET'),
    'code' => getenv('SAGE_CODE'),
    'grant_type' => 'authorization_code',
    'redirect_uri'=>'https://myurl.com/sage/refresh'
];

$response = $client->request('POST','/oauth2/token',['form_params' => $data]);

echo $response->getBody();

?>
