Flask - 使用 Nginx 隐藏在反向代理后面的 SocketIO
Flask - SocketIO hidden behind reverse proxy with Nginx
我想将 Flask-SocketIO 与我的 Flask 项目集成。我的应用 运行 在 Nginx 反向代理后面:
location /plivo_api{
rewrite ^/plivo_api(.*) / break;
proxy_pass http://127.0.0.1:8090;
}
所以我不明白 /plivo_api 中收到的所有流量将被重写为“/”端口 8090。这部分效果很好。
当我想连接到套接字时,问题就开始了。直接连接socket没问题
# all those examples work
# from localhost
var socket = io.connect()
var socket = io.connect('http://localhost:8090/')
# running the app out of the reverse proxy
var socket = io.connect('http://my_server:8090/')
但是通过 Nginx 我无法连接
# Bad Gateway
var socket = io.connect('http://my_server/plivo_api')
问题是我是否缺少连接到我的 socketio 应用程序的东西,或者是否有一些额外的东西要添加到 Nginx 配置中?
带有 socketio 集成的 flask 应用程序代码看起来像
# this code work well, the flask app and socket io
# problem must be in Ngin settings.
The flask app code with socketio integration looks like
from flask import Flask, render_template
from flask_socketio import SocketIO, emit
HOST = '127.0.0.1'
PORT = 8090
app = Flask(__name__)
app.config['SECRET_KEY'] = 'secret'
app.config['DEBUG'] = True
app.config['SERVER_NAME'] = f'{HOST}:{PORT}'
socketio = SocketIO(app)
@app.route('/')
def index():
return render_template('index.html')
if __name__ == '__main__':
socketio.run(app, port=PORT, host=HOST)
您需要在 nginx 中为 Socket.IO 端点创建一个特殊的位置块。您不能像对 HTTP 路由那样使用常规 URL。
documentation有个例子:
server {
listen 80;
server_name _;
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;
}
}
