movie插件经常超时 about slack_bot

[dongweiming]

movie超时的主要原因是豆瓣电影的图片做了防盗链的策略, 不能直接在slack里面显示, 所以我的做法是,下载图片, 把它传到slack的文件服务器上, 然后获得返回的url. 大部分的时间都浪费在下载和上传图片的时候.

我当时研究过改这个超时, 但是没有找到对应的设置方式

@firemiles @dongweiming 如果是heroku那边的超时，参考 https://devcenter.heroku.com/articles/request-timeout 这里有说明可以设置超时时间

或者在flask-slackbot这层，加一个handle超时处理的支持

@halfcrazy 你说的这个页面没有对我们这种环境的配置

[halfcrazy]

@dongweiming PROC文件web: gunicorn wsgi:app --timeout 240 --log-file -这里的--timeout 240，在heroku上是没用的，最大是30s，也就是默认的timeout。

By default, Gunicorn gracefully restarts a worker if hasn’t completed any work within the last 30 seconds.

我后来给heroku的帮助中心发了邮件, 问怎么修改. 它们给的回复是没法修改, 我们只能自己优化解决.

Hi,

30s timeout is Heroku router level timeout, so you can't use anything longer even though it's technically >configurable with Gunicorn (and I think your Gunicorn is actually using your timeout, but the response >just doesn't reach to the client because Heroku router already made a response with H12 errors). You'll >see H12 errors for any requests that take more than 30s as Steven explained, it's a hard limit of Heroku >platform and we can't extend this, unfortunately.

If you expect the request to be more than 30s, you'll need to optimize it or find some workaround.

Best,
