Initiating a download with authentication |
Mon, Aug 14 2017 11:42 AM | Permanent Link |
Matthew Jones | I would like to initiate a download using a TMenuItem action.
The easy way is window.open(URL, '_blank'); except that there is no authentication added. So I tried a TRequest, Request.RequestHeaders.Values['Custom-Auth'] := 'token ' + ActiveToken; which works fine, but the browser doesn't do anything with the content (even though the server says it is a download etc). So I figured a THTMLForm would work, but I cannot set a custom header, and it seems to be low level so hard to intercept. Anyone know how to do this? I could create a TLink I guess, and have the user click it, but if it can be done programmatically, that would be ideal. Hmm, except that there is no way to add the authentication to that either... -- Matthew Jones |

The next problem was it appeared to be working, but not doing anything. Only on the fourth try did I realise Chrome was downloading it quietly and showing me the button at the bottom of the page. -- Matthew Jones |
