发布使用php curl发布帖子请求

Question

我正在尝试使用curl使用php发布帖子请求但是json没有被传递到REST API。这是我的代码。在webservice中我获得的是null值。我不确定我哪里出错了。

    $email_json_data = json_encode($email_data);

    $header[] = "Content-type: application/json";

    $ch = curl_init($api_url);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
    curl_setopt($ch, CURLOPT_HEADER, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $email_json_data);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    $response = curl_exec($ch);
    return $response;

网络服务代码：

$email_json_data = $this->post('email_json_data');
$email_data = json_decode($email_json_data);

Answer 1

检查PHP: curl_errno

连接到服务器时可能存在问题，可能是您的$header之一。要了解更多信息，您需要显示（在生产中，记录它）卷曲错误。

将来，请尝试添加完整的代码示例，而不仅仅是代码段

从PHP: curl_strerror

添加的代码

class CurlAdapter
{ 
    private $api_url = 'www.somewhere.com/api/server.php';

    private $error = "";

    private function jsonPost($data)
    {
        // init curl
        $ch = curl_init($this->api_url);
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_HEADER, true);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

        // curl header
        $header[] = "Content-type: application/json";
        curl_setopt($ch, CURLOPT_HTTPHEADER, $header);

        // build post data
        $post_data = json_encode($data);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);

        // execute
        if (empty($response = curl_exec($ch)) {
            // Check for errors and display the error message
            if($errno = curl_errno($ch)) {
                $error_message = curl_strerror($errno);
                $this->error = "cURL error ({$errno}):\n {$error_message}";
                // @todo log curl error
            }    
        }

        // Close the handle
        curl_close($ch);

        return $response;
    }

    public function post( mixed $data ) 
    {  
        if (empty($this->jsonPost($data))) {
            return $this->error;
        }

        return $response;
    }    
}

$ca = new CurlAdapter();

echo $ca->post(['data' => 'testdata']);

想出一种方法来完成这项工作。

替换为$email_json_data = $this->post('email_json_data');

$email_json_data = file_get_contents("php://input");
