从 RPC 对象 php5.5 获取 JSON 数据

Question

我有一个 RPC 服务器 class，它使用 cURL 接受来自未指定的给定第 3 方的 JSON 数据。

我可以看到数据命中了我的 class，我可以将 var_dump 存储到一个似乎是服务器请求的文件中，但输出看起来像是在接收网络服务器信息并引用了入站对象。但是我没有看到我的 JSON 数据 'foo:bar'

<?php
class jsonRPCServer {
        public static function handle($object) {
                if (
                        $_SERVER['REQUEST_METHOD'] != 'POST' ||
                        empty($_SERVER['CONTENT_TYPE']) ||
                        $_SERVER['CONTENT_TYPE'] != 'application/json'
                        ) {
                        return false;
                }
                $request = json_decode(file_get_contents('php://input'),true);
                $args=func_get_args();
                ob_start();
                var_dump($_SERVER);
                $result2 = ob_get_clean();
                $file = 'stripedump.txt';
                $current = file_get_contents($file);
                $current .= $result2;
                file_put_contents($file, $current);
                try {
                        if ($result = @call_user_func_array(array($object,$request['method']),$request['params'])) {

                        }

                        header('content-type: text/javascript');
                        echo json_encode($response);

如何从入站 RPC 对象访问 JSON 数据？（特别是 'foo:bar'）

Answer 1

这只在自己使用时有效

<?php
        $request = file_get_contents('php://input');
        $args=func_get_args();
        ob_start();
        var_dump($request);
        $result2 = ob_get_clean();
        $file = 'stripedump.txt';
        $current = file_get_contents($file);
        $current .= $result2;
        file_put_contents($file, $current);
?>
