Mobile:

download:

andriod will override if you download twice, check navigator.userAgent.toLowerCase().indexOf('android') > -1,

we added timeStamp to the file name, so it will not override

ios cannot download: check anchorElement.download === undefined

if it's ios, we will just window.open(reder.result, '_blank');

cookie, HTTP Interceptors:

we use HTTP Interceptors to intercept the AJAX request such as the content json file, because we need to add some http headers into the request.
