IE11中的访问被拒绝错误

Question

I am getting 'Access is denied' error with IE11 with my Angular project. This works fine in Chrome. I am not able to figure what is going wrong with IE as I am relatively new to web development with javascript and Angular.

Can someone help me with what is going wrong with IE11 for the below code please?

this.http.get(url)
    .subscribe(
        res => {
            if (typeof(logInfo.callBack) === 'function') {
                logInfo.callBack(res);
            }
        }
    );

It looks like a CORS related issue.

The IE browser is using XDomainRequest which involves some limitations. One of them is: the protocol must be preserved (requests are allowed from HTTP to HTTP, from HTTPS to HTTPS. Other protocols are prohibited).

So, if you app is loaded over 'https' but is trying to load the resource over "http" or vice versa, than the request will be blocked by IE browser.
