使用 CURL 通过 JSON 传递变量

Question

如何通过 JSON 将表单变量传递到另一个页面？我创建了两个 php 文件，文件名为 page_login.php 和 login.php。但是在运行 login_post.php 时，$json 值无法传递给 login.php

page_login.php:

$email = [e-mail];

$password = 123;

$json = array('email' => $email, 'password' => hash("sha256",$password));

$json = json_encode($json);

$ch = curl_init();      

curl_setopt($ch, CURLOPT_URL,"https://localhost/login.php");

curl_setopt($ch, CURLOPT_POST, 1);

curl_setopt($ch, CURLOPT_POSTFIELDS, $json);                                                                                                           

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$server_output = curl_exec($ch);

curl_close ($ch);

登录.php：

$json=json_decode($_REQUEST["json"],true);

print $json;
