php 利用curl通过post方式传递json

<?php
/**
* Created by PhpStorm.
* User: gywtzh
* Date: 2016/11/25
* Time: 14:53
*/
//echo phpversion();
$data = array('name' => '李四', 'age' => '26');
$data_string = json_encode($data,JSON_UNESCAPED_UNICODE);
//echo $data_string;
$ch = curl_init('http://localhost/receiverpost.php');

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS,$data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($data_string))
);

$result = curl_exec($ch);
echo $result;
?>

receiverpost.php的代码

<?php
/**
* Created by PhpStorm.
* User: gywtzh
* Date: 2016/11/25
* Time: 14:56
*/
//echo file_get_contents("php://input");
$data = json_decode(file_get_contents("php://input"), true);
echo $data["name"];
echo $data["age"];
?>

http://localhost/senderpost.php进行测试，可以成功获得数据

不过php文件和测试浏览器都要用utf-8的编码格式，否则也会出错
