范例如下

<?php
/**
 * PHP发送Json对象数据
 *
 * @param $url 请求url
 * @param $jsonStr 发送的json字符串
 * @return array
 */
function http_post_json($url, $jsonStr)
{
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonStr);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
            'Content-Type: application/text/plain; charset=utf-8',
            'Content-Length: ' . strlen($jsonStr),
            'Accept-Encoding: gzip, deflate'
        )
    );
    $response = curl_exec($ch);
    $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    curl_close($ch);
 
    return array($httpCode, $response);
}
