PHP 无法识别 ajax 发布的数据

Question

我正在向我的 PHP 脚本发送 ajax 调用，如下所示:

function load(){
    var request = {};
    request['action'] = 'load';
    request['file'] = 'lorem_ipsum.txt';
    $.ajax({
        type: 'POST',
        url: cgi_file,
        data: JSON.stringify(request),
        processData: false,
        dataType: 'html',
        contentType: 'application/html',
        success:function(response){
            console.log("received " + response);
        }
    });
}

我的PHP脚本如下:

$content_dir = '/static/content/';

$action = $_POST['action'];

switch ($action){
    case 'load':
        $file = $_POST['filename'];
        echo file_get_contents($content_dir . $file);
        exit();
}

PHP 响应以下错误:

Notice: Undefined index: action in /var/www/river/api.php on line 5

这里有什么问题吗？

尝试放弃 processData: false 和 contentType: 'application/html' 它应该可以工作

$.ajax({
    type: 'POST',
    url: cgi_file,
    data: request,
    dataType: 'html',
    success:function(response){
        console.log("received " + response);
    }
});
