php - 我将如何编写这个curl请求

Question

您好，我正在使用 API。 API 文档中明确写道，所有数据均以 JSON 形式发送和接收，并采用 UTF-8 编码。之后他们给出了一行

$ curl -­-­user name:password https://api.abc.de/erer

我只是想问我如何发送上面提到的curl请求？用户名和密码将作为 GET、POST 或在 headers 中发送？

我正在使用以下代码，但收到空数组。文档说它必须接收一些错误或成功代码。

$ch = curl_init();
            $post_data = array('username'=>$_POST['username'],'password'=>$_POST['password']);
            $post_data = http_build_query($post_data);
            curl_setopt($ch, CURLOPT_URL, $url);
            curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
            curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
            curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
            curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
            curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
            curl_setopt($ch, CURLOPT_USERPWD, 'username:password');

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

            $result = json_decode($result);
            $result = (array) $result;
            echo "<pre>";
            print_r($result);
            echo "</pre>";
            die();

我已经打印出 curl_get_info 的响应，即

Array

[url] => https://api.abc.de/erer
[content_type] => 
[http_code] => 0
[header_size] => 0

根据提供的信息，假设您正在发出 POST 请求，类似的操作应该可以工作:

$post_data = http_build_query( $post_array );
$url = 'https://api.abc.de/erer';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERPWD, 'name:password');
$data = curl_exec( );
curl_close($ch);

$post_data 应包含要发送的 key => 值的关联数组。 我相信您的用户名:密码已在 header 中发送，但 PHP.net 没有说明。
