The only things that differ from doing a regular POST request with XMLHttpRequest when you are sending XML are that you must:
与在发送 XML 时使用 XMLHttpRequest 执行常规 POST 请求不同的是，您必须：
- Use
setRequestHeader("Content-Type: application/xml")to specify that you are sending XML. - When you
send(data)make sure thatdataconsists of a string representation of your XML (i.e. don't leave it as a DOM object).
- 使用
setRequestHeader("Content-Type: application/xml")指定要发送XML。 - 当您
send(data)确保它data由您的 XML 的字符串表示组成时（即不要将其保留为 DOM 对象）。
I have tried everything but I get a status as 0 but readystate as 1 and then 4
我已经尝试了所有方法，但我的状态为 0，但就绪状态为 1，然后为 4
It sounds like you are making a cross-origin request and you don't have permission. Look at your browser's error console. It is probably complaining about that. See this questionif that is the case.
听起来您正在发出跨域请求，但您没有权限。查看浏览器的错误控制台。它可能是在抱怨那个。如果是这种情况，请参阅此问题。
