actionscript-3 - URLRequest/URLLoader 自动将 POST 请求转换为 GET

Question

当我执行以下代码时:

var urlRequest:URLRequest = new URLRequest("http://somehost/with/some/path?andsomequerystring=true");
urlRequest.method = 'POST';
var urlLoader:URLLoader = new URLLoader(urlRequest);
urlLoader.addEventListener(Event.COMPLETE,  function(event:Event):void{
    trace('sweet');
});

由于查询字符串的存在，它将我的显式 POST 请求转换为 GET。如果我删除查询字符串(并序列化为 POST 正文的一部分)，它会成功发出相应的 POST 请求。有什么办法可以防止它这样做吗？我的服务器要求使用查询字符串发出 POST 请求。

啊，我想我找到了答案，看来你还必须指定一个正文，否则它仍会作为 GET 请求从他们的文档中发送:

Note: If running in Flash Player and the referenced form has no body, Flash Player automatically uses a GET operation, even if the method is set to URLRequestMethod.POST. For this reason, it is recommended to always include a "dummy" body to ensure that the correct method is used.
