如何设置 XDomainRequest 对象的内容类型？

Question

for XMLHttpRequest it is pretty easy:

var xhr = new XMLHttpRequest();
xhr.open('POST', MyUrl, true);
xhr.setRequestHeader('Content-Type', 'application/json')

But how do I achieve this for XDomainRequest?

Answer 1

It's not possible to override the XMLHttpRequest content-type. You should set it correctly on the server eg for php:

header('Content-type: application/json');

If this is not possible, then you can create a local proxy script which mirrors your crossdomain script with the correct header
