我有以下代码。当我使用 api 客户端发布帖子时,它会成功输出完整的 json。
但是当我使用 jQuery 时,它会抛出一个 json 解析错误。
我想知道如何在 jQuery 中操作 json 数据和对象。我正在尝试制作宁静的 api。所以请帮助我。

我的PHP代码:
<?php
$email=$_POST['email'];
$pwd=$_POST['pwd'];
header('Access-Control-Allow-Origin: *');
$jsonString = file_get_contents(dirname(__FILE__) . "/db/user.json");
$data = json_decode($jsonString);
foreach ( $data->user as $user )
{
if( $user->email == $email && $user->password ==$pwd )
{
//header('Content-Type: application/json');
echo($user);
}
else
{
echo"Fail";
}
}
?>
我的 json 文件
{
"user": [
{
"username": "hiren",
"email": "a",
"password": "a",
"que": "Favourite Pet",
"ans": "Montu"
}
]
