Javascript nginx tornado上的websocket连接立即关闭
我真的很想用nginx配置tornado websocket连接配置,最后我遇到了一个问题,但我无法解决。我的配置有错误吗? 这是我的websocket.py:Javascript nginx tornado上的websocket连接立即关闭,javascript,nginx,websocket,tornado,Javascript,Nginx,Websocket,Tornado,我真的很想用nginx配置tornado websocket连接配置,最后我遇到了一个问题,但我无法解决。我的配置有错误吗? 这是我的websocket.py: class Application(tornado.web.Application): def __init__(self): handlers = [ (r"/", ChatSocketHandler) ] settings = dict(

这是我的客户端脚本:
<script>
let url = "ws://104.131.115.151:8888/";
let socket = new WebSocket(url);
socket.onmessage = function(event) {
console.log(event);
};
socket.onopen = function () {
console.log('opend');
socket.send('Hello World')
};
socket.onclose = function () {
console.log('closed');
};
</script>
在没有nginx配置的本地计算机上运行时:
opened
MessageEvent{...}
map $http_upgrade $connection_upgrade {
default upgrade;
'' close;
}
upstream pythonserver {
server 127.0.0.1:8888;
}
server{
listen 80;
server_name 209.97.139.107;
location /chatsocket {

uwsgi_pass unix:/home/apideveloper/api/app.sock;
}
location / {

}
这是我的nginx配置:

另外,我正在使用云和我的服务器url,很可能您的nginx配置不完整 当浏览器尝试连接到websocket时,它会发送
升级
和连接
http头。这会告诉服务器升级到websocket的连接
问题(也是一个常见的问题)似乎是浏览器正在将升级头发送到nginx,但nginx没有将这些头发送回Tornado。要成功连接websocket,升级头必须到达Tornado后端
解决方案:
解决方案是告诉Nginx将升级头发送回Tornado,以便完成websocket连接
您的配置应如下所示:
location / {
# ... other variables ...
# variables for websocket
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
}
重新加载您的Nginx服务器,它应该可以工作。我也尝试过,但无法工作。请参见下面的我的Nginx配置。
