Question

我目前正在使用包含聊天功能的社交网络Web应用程序，当我在本地主机上时，聊天工作正常。我遇到的问题是，当我尝试将客户端连接到（托管）服务器时，我从SocketIO中收到错误消息。

错误看起来像这样：GET http://127.0.0.1/socket.io/?EIO=3&transport=polling&t=N1Kh0TS net :: ERR_CONNECTION_REFUSED

现在，我已经尝试使用网络上的随机解决方案解决此问题很长时间了，但是我对此并不太确定。

run.py：

from random import app, socketio

if __name__ == '__main__':
    socketio.run(app, debug=True)

在routes.py中，我的连接事件如下：

@socketio.on('user_con')
def receive_connection(data):
    # join the desired channel
    join_room(data['channel'])
    print('User ' + str(data['user']) + ' successfully joined channel : ' + str(data['channel']))

客户端这样连接：

//Connect the socket to our server
   var socket = io.connect('http://127.0.0.1:5000');
        socket.on('connect', function() {
          var connection_data = {
            user : '{{ current_user.id }}',
            channel : '{{ channel.name }}'
          }
          //send the connection data
          socket.emit('user_con', connection_data);
        });

请注意，该代码在本地计算机上确实运行良好，但尚未部署。一切都托管在Linux服务器上。

非常感谢您的帮助。 谢谢。

EDIT2：这是我们的Nginx文件

server {
    server_name #censored#;

    location /static {
        alias /home/admin/Prototyp_1/#censored#/static;
    }

    location / {

        proxy_pass http://localhost:8000;
        include /etc/nginx/proxy_params;
        proxy_redirect off;
    }

    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/#censored#/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/#censored#/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot



}

server {
    if ($host = #censored#) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    if ($host = #censored#) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    listen 80;

    server_name #censored#;
    return 404; # managed by Certbot
}

edit3：我们在代码中添加了以下内容

    location /socket.io {
        include proxy_params;
        proxy_http_version 1.1;
        proxy_buffering off;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
        proxy_pass http://127.0.0.1:5000/socket.io;
    }

有趣的是，当我们将html中的端口更改为5000时，错误为“对接拒绝”，当端口为8000时，错误为“不允许原点”

部署时Flask-SocketIO拒绝连接
