如何将json请求转换为php并以php格式获取json值

Question

这是对我的服务器的JSON POST请求。它直接来自android应用。

{
"appPackage": "tkstudio.autoresponderforwa",
"messengerPackageName":"com.whatsapp",
"query":{
      "sender":"John Smith",
       "message":"This is an example!",
       "isGroup"; false,
       "ruleId": 42
}

}

这是我服务器上的完整代码，不包括数据库连接调用

// database details
......
define("_CONFIG", true);

// required headers

header("Access-Control-Allow-Origin: *");
header("Content-Type: application/json; charset=UTF-8");
header("Access-Control-Allow-Methods: POST");
header("Access-Control-Max-Age: 3600");
header("Access-Control-Allow-Headers: Content-Type, Access-Control-Allow-Headers, Authorization, X-Requested-With");

$data = json_decode(file_get_contents("php://input"));

$stmt = $db->prepare("SELECT * FROM users");
$stmt->execute();
$row = $stmt->fetch(PDO::FETCH_ASSOC);

if($query["message"] == $row['reg_username']){
    $name = $row['reg_email'];
} else { 
    $name = "Name not in our database";
}
// make sure data is not empty

if( !empty($data->query) &&
    !empty($data->appPackageName) &&
    !empty($data->messengerPackageName)
){
    // set response code - 200 success
    http_response_code(200);
    // tell the user
    echo json_encode(array("replies" => array(
                            array("message" => "Success!"),
                            array("message" => $name)
                            )
                        )
                    );
}

现在，请求来自上面的json文件，直接来自android应用程序

我尝试过，它的工作原理就像是一种魅力：

$json = '{
           "appPackage": "tkstudio.autoresponderforwa",
           "messengerPackageName":"com.whatsapp",
           "query":{
           "sender":"John Smith",
           "message":"This is an example!",
           "isGroup": false,
           "ruleId": 42
         }
}';

$res = json_decode($json);

var_dump($res->query->message);//show string(19) "This is an example!"
