使用Nginx的流星WebSocket握手错误400

WebSocket速度很快，您不必（也不应该）禁用它们。

导致此错误的真正原因是Webfactions使用nginx，并且nginx配置不正确。通过设置和，以下是正确配置nginx代理WebSocket请求的方法：

proxy_set_headerUpgrade $http_upgrade;``proxy_set_header Connection $connection_upgrade;

# we're in the http context heremap $http_upgrade $connection_upgrade {  default upgrade;  ''      close;}# the Meteor / Node.js app serverserver {  server_name yourdomain.com;  access_log /etc/nginx/logs/yourapp.access;  error_log /etc/nginx/logs/yourapp.error error;  location / {    proxy_pass http://localhost:3000;    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;    proxy_set_header Host $host;  # pass the host header - http://wiki.nginx.org/HttpProxyModule#proxy_pass    proxy_http_version 1.1;  # recommended with keepalive connections - http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_http_version    # WebSocket proxying - from http://nginx.org/en/docs/http/websocket.html    proxy_set_header Upgrade $http_upgrade;    proxy_set_header Connection $connection_upgrade;  }}

这是基于David Weldon的nginxconfig的改进的nginx配置。安德鲁·毛（Andrew
Mao）已经达到了非常相似的配置。

请记住，还要将HTTP_FORWARDED_COUNT环境变量设置为应用程序前面的代理数量（通常为1）。
