Is it possible to send custom headers with an XHR (“Ajax” request)?

问题

I'm working with an API which needs extra security information sent along with an HTTP request as meta-information in headers. Is it possible to set those in an XMLHttpRequest?

回答1:

Yes, see "The setRequestHeader() method" of the current XMLHttpRequest working draft of 6 December 2012.
