我已扩展WP API 插件提供可以处理文档的API。

Routes

public function register_routes($routes)
{
    $documents_routes = array(
        \'/v1/documents\' => array(
            array(array($this, \'create_document\'), WP_JSON_Server::CREATABLE),
        )
    );
    $new_routes = array_merge($routes, $documents_routes);
    return $new_routes;
}

callback function

public function create_document($data, $_files = null){

    if(!empty($_files)) {
        // process file
    }


    // how to retrieve 
}

Request

POST /api/v1/documents/ HTTP/1.1

The Problem

我有一些属性，如doc\\u id、case\\u reference、description、author、size等，这些属性将随文件一起传递给api。

现在的问题是，如果使用内容类型：表单数据，我希望能够检索所有数据。高效检索回调函数中传递的所有数据的最佳方法是什么？

public function create_document($_files = null){

    if(!empty($_files)) {
        // process file
    }

    $data = $_POST;
    // process $data is you want

    // $data[\'doc_id\']
    // $data[\'case_reference\']
    .....
    .....
