试试，结果问题依旧。
去把之前的FLASK_SECRET_KEY改为SECRET_KEY：

问题依旧
-》本身应该的确也没有什么影响。
Flask-SocketIO socket.io.min.js GET 400 (BAD REQUEST
javascript – SocketIO 400 Bad Request Error – Stack Overflow
javascript – flask socketio 400 (BAD REQUEST) – Stack Overflow
此处有点点进步：
然后通过给SocketIO加上调试参数engineio_logger=True：
# socketio = SocketIO(app) socketio = SocketIO(app, engineio_logger=True) |
之后，可以看到输出的io的log了：

Flask-SocketIO Invalid session
Invalid session Sending packet MESSAGE data 0
Invalid session · Issue #29 · miguelgrinberg/python-engineio · GitHub
提到：
“
The invalid session indicates that the server process received a Socket.IO request with a session it does not know about.
Possible causes I can think of:
you have multiple gevent servers. If server #1 creates the session, but then server #2 receives a subsequent request you will get this message. The solution is to either ensure multiple servers are handled with sticky sessions, or else use a single server.
your log does not show the times of each message. A session is removed after 60 seconds of inactivity (the value of the "pingTimeout" argument returned in the open packet).
”
但是不知道如何去：
use a single server
好像就是：
（此处的gunicorn的）worker设置为1个？
log中，好像也是开启了多个线程：
[2016-10-28 20:05:43 +0000] [1673] [INFO] Listening at: http://0.0.0.0:21085 (1673) [2016-10-28 20:05:43 +0000] [1673] [INFO] Using worker: sync [2016-10-28 20:05:43 +0000] [1682] [INFO] Booting worker with pid: 1682 [2016-10-28 20:05:43 +0000] [1683] [INFO] Booting worker with pid: 1683 [2016-10-28 20:05:43 +0000] [1684] [INFO] Booting worker with pid: 1684 [2016-10-28 20:05:43 +0000] [1685] [INFO] Booting worker with pid: 1685 Server initialized for gevent.

或许就是意味着：
开了多个server？
那去试试：
把：
/Users/crifan/dev/dev_root/daryun/Projects/RunningFast/sourcecode/RunningFast-Server/supervisor.conf
中的：
[program:runningfast_stable] command=/root/Envs/RunningFast/bin/gunicorn -w 4 -b 0.0.0.0:21084 run:app & |
的worker改为1个：
command=/root/Envs/RunningFast/bin/gunicorn -w 1 -b 0.0.0.0:21084 run:app & |
然后再去试试
-》
但是这样不就是：
少了worker
以后处理HTTP请求，性能就差了吗？
结果去
supervisorctl -c supervisor.conf restart runningfast_staging
结果还是有4个进程：

干脆去命令行执行：

去试试：

此处，好像某一次，emit生效了，可以收到emit的内容了：
去看看，其中对应的log内容：

以为解决了问题。
但是再去多测试几次，后来还是经常出错：

把最新的19.6的gunicorn去换成gunicorn 18.0
再去单独运行：
gunicorn -w 1 -b 127.0.0.1:21085 run:app &
结果又出现其他错误：
【未解决】把gunicorn从19.6降级为18.0后supervisorctl运行出错：gunicorn: error: No application module specified

再加上：
