带nginx + uwsgi + flask-socketio的WebSockets

Question

我正在尝试使用前端的socket.io和后端的Flask-Socketio建立一个websocket连接。然而，前端给了我一个错误

WebSocket connection to 'ws://myserver.com/socket.io/?EIO=3&transport=websocket&sid=0514a0aa99f346e7ad717770f9911c89' failed: WebSocket is closed before the connection is established.

我感觉这是因为我的uwsgi或nginx配置。

下面是我使用的uwsgi配置：

[uwsgi]
base = /var/www/webapp
file = %(base)/run.py
callable = app
pythonpath = %(base)
socket = /tmp/uwsgi.sock
chmod-socket = 666
http-websockets = true
gevent = 1000
processes = 1
threads = 2
enable-threads = true
single-interpreter = true
master = true
chdir = /var/www/webapp
fs-reload = %(base)/app/
touch-reload = %(base)/run.py
py-autoreload = 1
harakiri = 3600

下面是nginx配置的相关部分：

    location /socket.io/ {
        auth_basic "Restricted";
        auth_basic_user_file /etc/nginx/.htpasswd;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
        include uwsgi_params;
        uwsgi_pass unix:/tmp/uwsgi.sock;
    }

是否有问题使用

socket = /tmp/uwsgi.sock

在uwsgi配置中使用

uwsgi_pass unix:/tmp/uwsgi.sock;

从nginx配置中？任何帮助都将不胜感激。当然，如果我需要提供更多信息，请告诉我。

您应该将uwsgi_pass unix:/tmp/uwsgi.sock;更改为uwsgi_pass unix:///tmp/uwsgi.sock;。
