[英]IE9 CORS XDomainRequest Access Denied
I'm keep getting 'Access Denied' when doing XDomainRequest in IE9.在 IE9 中执行 XDomainRequest 时,我不断收到“拒绝访问”的消息。
I Have tried lots of different solutions, nothing works so far.我尝试了很多不同的解决方案,到目前为止没有任何效果。
Note: the script is on HTTP while the server it's doing request to is HTTPS注意:脚本在 HTTP 上,而它正在请求的服务器是 HTTPS
Below is my code:下面是我的代码:
let xhr = new XMLHttpRequest();
if ('withCredentials' in xhr){
xhr.open('POST', XHR_URL, true);
} else if (typeof XDomainRequest != 'undefined'){
xhr = new XDomainRequest();
xhr.open('POST', XHR_URL);
} else {
xhr = null;
return;
}
xhr.setRequestHeader('Content-type', 'text/plain');
xhr.onreadystatechange = () => {
if(xhr.readyState == 4 && xhr.status == 200) {
// do something
}
}
xhr.onprogress = function () { };
xhr.ontimeout = function () { };
setTimeout(function () {
xhr.send(params);
}, 0);
Need help, Thanks!需要帮助,谢谢!
If you start on IE9, then your xhr
calls new XDomainRequest
(aka xdr).如果您从 IE9 开始,那么您的
xhr
将调用新的XDomainRequest
(又名 xdr)。 But, xdr
doesn't have ' setRequestHeader
'.但是,
xdr
没有“ setRequestHeader
”。
