make your content type as "application/json; charset=utf-8", as follows
使你的内容类型为“application/json; charset=utf-8”，如下
$(document).ready(function() {
$.ajax({
type: "POST",
url: "RSSReader.asmx/GetRSSReader",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(msg) {
// Hide the fake progress indicator graphic.
$('#RSSContent').removeClass('loading');
// Insert the returned HTML into the <div>.
$('#RSSContent').html(msg.d);
}
});
});

in my case it was failing becasue of there was not POST method in servet, but I had GET method.
就我而言，它失败了，因为服务器中没有 POST 方法，但我有 GET 方法。
so I jsut changed the type:"GET", so it is working now.
所以我只是改变了类型：“GET”，所以它现在可以工作了。
