All stuffs doesn't work after proxy.

[WALL-EEEEEEE]

   I have a proxy in my computer for some essential reasons. After I had installed sx.el into my Emacs, I tried to use some functions of it, sx-search or sx-tab-all-questions. All of them didn't work. I just received an error all the same, Args out of range "" 2.I think this may be a bug in sx.el behind the proxy.

Have you configured your emacs to work with your proxy?

[WALL-EEEEEEE]

Yes, it can be made to work just by setting *stack* domain name in no_proxy.I meant I can't use this plugin after the proxy, however the package.el works under it very well. So I think it may be the plugin's problem.

Have you seen #317? It sounds like a similar situation.

If you're already on emacs 25.1 (or updating doesn't solve your problem or #317's solution doesn't work), I'll try to get to this within the month, but I can't promise anything. I'm not really familiar with the underworkings of url.el 😦

[WALL-EEEEEEE]

   It doesn't help. My Emacs version is upper 25.1.

Unless I can reproduce it, I really can't help. Do you have instructions on how to reproduce your setup? Can you provide a backtrace?

[WALL-EEEEEEE]

Just set your proxy up on your computer at first, I use privoxy for my terminal. Then, remove the proxy inside your ~/.emacs if they are there. Third, check if your package.el works well after the proxy to make sure your proxy is no problem.
After all the processes above, install sx and run it. I think it will be reproduced.
One thing more I need to mention, My OS is Gentoo and Emacs version is 25.2.That's all. Hope this will be helpful.

[WALL-EEEEEEE]

However, I ain't very familiar with Emacs, can you tell me how to debug it so I can give you some detail backtrace infos.

[vermiculus]

M-x toggle-debug-on-error and reproduce the error.

These are all the outputs.Hope it will be helpful.

Looks like the problem is coming from sx-request.el:192. I could easily make this a better error, but it looks like you're not getting any data at all from the request.

Can you try evaluating this code block after sx is loaded and then trying the request?

(defun sx-encoding-gzipped-p (data)
  (let ((unidata (string-as-unibyte data)))
    (when (<= 2 (length unidata))
      (equal (substring unidata 0 2)
             (unibyte-string 31 139)))))

I don't believe this will make it work, but it should give a better error (like 'end of file while parsing JSON').

The next step will be to figure out why url is failing to get the response through your proxy.
