给予Guzzle中的query-option：

$endpoint = "http://my.domain.com/test.php";
$client = new \GuzzleHttp\Client();
$id = 5;
$value = "ABC";

$response = $client->request('GET', $endpoint, ['query' => [
    'key1' => $id, 
    'key2' => $value,
]]);

// url will be: http://my.domain.com/test.php?key1=5&key2=ABC;

$statusCode = $response->getStatusCode();
$content = $response->getBody();

// or when your server returns json
// $content = json_decode($response->getBody(), true);

我使用这个选项来构建我的get-requests和guzzle。结合json_decode（$json_values，true），你可以把json转换成php数组。

如果您在使用guzzlehttp：

原生Php方式

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "SOME_URL_HERE".$method_request);
// SSL important
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

$output = curl_exec($ch);
curl_close($ch);

$this - > response['response'] = json_decode($output);

有时这个解决方案仍然比使用Laravel框架中附带的库更好和更简单。但仍然是你的选择，因为你掌握着你的项目的开发。

使用此代码作为参考。我已经成功地使用此代码进行了curl GET请求

public function sendSms($mobile)
{
  $message ='Your message';
  $url = 'www.your-domain.com/api.php?to='.$mobile.'&text='.$message;

     $ch = curl_init();
     curl_setopt($ch, CURLOPT_URL, $url);
     curl_setopt($ch, CURLOPT_POST, 0);
     curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

     $response = curl_exec ($ch);
     $err = curl_error($ch);  //if you need
     curl_close ($ch);
     return $response;
}

您忘记在名称空间前添加\。
您应该填写：

$response = $client->post($endpoint, [
                \GuzzleHttp\RequestOptions::JSON => ['key1' => $id, 'key2' => 'Test'],
            ]);

而不是：

$response = $client->post($endpoint, [
                GuzzleHttp\RequestOptions::JSON => ['key1' => $id, 'key2' => 'Test'],
            ]);

我相信，自从Laravel 7以来，Laravel就有了一个HTTP客户端，这是一个Guzzle HTTP的 Package 器。

use Illuminate\Support\Facades\Http;

$response = Http::get('http://my.domain.com/test.php', [
    'key1' => $id, 
    'key2' => 'Test',
]);

if ($response->failed()) {
   // return failure
} else {
   // return success
}

这是令人惊讶的，而且更干净，更容易测试，here's the documentation

使用Laravel，你可以写这样的东西在你的路线文件，如果你正在使用WP，你觉得冒险，不想使用狂饮或Laravel cURL包.

Route::get('/curl',function() {
    $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, 'https://example.net/wp-login.php');
    
    // save cookies to 'public/cookie.txt' you can change this later.
    curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');

    curl_setopt($ch, CURLOPT_POSTFIELDS, ['log'=>'<name>','pwd'=>'<pass>']);

    curl_exec($ch);

    // supply cookie with request
    curl_setopt($ch, CURLOPT_COOKIE, 'cookie.txt');

    // the url you would like to visit
    curl_setopt($ch, CURLOPT_URL, 'https://example.net/profile/');

    $content = curl_exec($ch);

    curl_close($ch);

    // webpage will be displayed in your browser
    return;
});
