XmlHttpRequest can only be used to call services local to the domain/server from where the page is being served.

Thus, if you're serving a page from:

http://www.example.com/page1

You cannot make an XmlHttpRequest to:

http://www.sample.com/webservice

由于您正在设置Content-type，因此您还需要将其设置为使用UTF-8。我认为它应该是application/xml（来源）。

xmlhttp.setRequestHeader("Content-Type", "application/xml; charset=utf-8");

否则，您是否验证过 XML 格式正确？尝试将其保存为完整的 XML 文件并在浏览器中打开它。
