使用 Laravel 进行 Guzzle 发送 application/x-www-form-urlencoded 请求答案

【问题标题】：Guzzle with Laravel send an application/x-www-form-urlencoded request使用 Laravel 进行 Guzzle 发送 application/x-www-form-urlencoded 请求
【发布时间】：2020-07-21 17:46:10
【问题描述】：

在 Laravel 中使用 Guzzle 发出 POST 请求时，我不断收到此错误：

{
data: {
error: "invalid_client"
}
}

我 100% 确定 ID 和机密是正确的，因为它在 Postman 中工作。这是我的代码。

$client = new GuzzleHttp\Client();
        try {
            $res = $client->request('POST', 'https://example.com', [

                'form_params' => [
                    'grant_type' => '*',
                    'client_id' => '*',
                    'client_secret', '*',
                    'scope' => '*',
                    'connector' => '*',
                    'api_token' => '*',
                ]

            ]);

            $res = json_decode($res->getBody()->getContents(), true);
            dd($res);


        } catch (GuzzleHttp\Exception\ClientException $e) {
            $response = $e->getResponse();
            $result = json_decode($response->getBody()->getContents());

            return response()->json(['data' => $result]);

        }

谁能帮帮我？我也试过这个标题：

 'headers' => [
                        'Content-Type' => 'application/x-www-form-urlencoded',
                    ],

这是工作邮递员代码。这工作正常。也许任何人都可以看到 Guzzle 中可能缺少什么？

标签： laravel post postman guzzle

【解决方案1】：

如果你尝试 Guzzle 周围的 laravel Facade 会发生什么？

步骤如下：

// make sure the composer component is installed in console
composer require guzzlehttp/guzzle

// don't forget include at top of Controller
use Illuminate\Support\Facades\Http;

// inside function
$response = Http::post('http://test.com/users', [
    'name' => 'Steve',
    'role' => 'Network Administrator',
]);

dd($response->json());

【讨论】：

由于某种原因，我无法正常工作。添加使用 Illuminate\Support\Facades\Http 时未定义的类；在控制器中。
但您确实执行了 composer require 命令，对吧？也许你还必须做一个 composer dump && composer install .. 这也是来自 laravel 7 的文档，如果已经成功使用它的话..
是的，我确实运行了 composer require guzzlehttp/guzzle。使用 laravel 5.6
哦，好吧，这行不通。那个 laravel 包装器当时还不存在

【解决方案2】：

试试这个，对我来说很好用

$client = new \GuzzleHttp\Client();
$response = $client->request('POST', 'https://example.com', [
       'headers' => ['Content-type: application/x-www-form-urlencoded'],
       'form_params' => [
            'grant_type' => '*',
            'client_id' => '*',
            'client_secret', '*',
            'scope' => '*',
            'connector' => '*',
            'api_token' => '*',
                ],
       'timeout' => 20, // Response timeout
       'connect_timeout' => 20, // Connection timeout
        ]);

dd($response->getBody()->getContents());

【讨论】：

继续获取：客户端错误：POST https:/example.com/connect/token 导致 400 Bad Request 响应：{"error":"invalid_client"}
这是您尝试调用的服务器的响应，我认为您缺少调用所需的身份验证数据，但 guzzle 没有问题
谢谢。我已经添加了工作邮递员代码。你能看出 Guzzle 中可能缺少什么吗？
我相信guzzle没有问题，如果您能提供邮递员的工作数据，我将能够提供帮助。
请检查代码。这是我现在的主要问题。

【解决方案3】：

发现问题。愚蠢的错字。在“client_secret”中缺少“=>”。
