extension is null when calling download video in wechat.media

[gabrieltong]

when downloading media , wechat try to guess the extension , and add the right extension .

when downloading a video media , the guess failed , and the extension is null . so the downloaded file name will be added a extra '.'

for example, if $MediaId(video) is abcd, the final url will be abcd.

if we can't get the extension , can we not add the ext ?

if the filename param contains a ext , can we trust it and not add the ext ?
