如何添加此验证并相应地更改响应。谢谢你的帮助，谢谢

你可以这样做

<?php
        header('Content-type: application/json');
        if($_GET["user"])
        {
             $user = $_GET["user"];
             // write your code that will use the user name
        }
        else
        {
            // return error or anything said the user is missing
        }

?>

{
    result: [
        {
            say: "omg",
            dsay: "D omg",
        },{
            say: "bla",
            dsay: "D bla",
        },
    ]
}

<?php
        header('Content-type: application/json');
        if($_GET["user"])
        {
             $user = $_GET["user"];
             // write your code that will use the user name
        }
        else
        {
            // return error or anything said the user is missing
        }

?>
