我正在运行一个使用 gevent-socketio 的 django 项目。
出于某种原因,在我的开发服务器上,我的所有 websockets 请求都返回一条101 pending
消息,socketio 将在该消息处开始循环遍历所有其他协议,从而导致pending
状态。
我的 uwsgi 日志中的错误是:
2013/05/23 16:09:08 [error] 14485#0: *85 upstream timed out (110: Connection timed out) while reading upstream, client: x.x.x.x, server: dev.proj.co, request: "GET /socket.io/1/xhr-polling/116404981619?t=1369325348489 HTTP/1.1", upstream: "http://127.0.0.1:4042/socket.io/1/xhr-polling/116404981619?t=1369325348489", host: "dev.proj.co", referrer: "http://dev.proj.co/map/bycon/"
在本地,我没有这个问题。我使用启动服务器python run.py
在我的本地环境中运行.py
