Set referer for xml.HTTP.Request?
提问by user198989
I am successfully sending xml.http.request by using
我通过使用成功发送 xml.http.request
var createCORSRequest = function(method, url) {
var xhr = new XMLHttpRequest();
if ("withCredentials" in xhr) {
// Most browsers.
xhr.open(method, url, true);
} else if (typeof XDomainRequest != "undefined") {
// IE8 & IE9
xhr = new XDomainRequest();
xhr.open(method, url);
} else {
// CORS not supported.
xhr = null;
}
return xhr;
};
var url = 'http://www.whatismyip.com';
var method = 'GET';
var xhr = createCORSRequest(method, url);
xhr.onload = function() {
// Success code goes here.
};
xhr.onerror = function() {
// Error code goes here.
};
xhr.setRequestHeader('referer', 'http://www.google.com');
xhr.send();
However, I couldnt able to define my referer. What is the correct way to add the custom referer ?
但是，我无法定义我的推荐人。添加自定义引用的正确方法是什么？

You cannot. The XMLHttpRequest specification forbidsthe altering of the refererheader (this stops sites lying in it to bypass security checks which some sites use the referer for).
你不能。所述的XMLHttpRequest规范禁止所述的改变referer报头（此停止躺在它的一些网站使用引荐旁路安全检查点）。
Terminate these steps if header is a case-insensitive match for one of the following headers:
- …
- Referer
- …
如果标头是以下标头之一的不区分大小写的匹配，则终止这些步骤：
- …
- 推荐人
- …
