Websockets出现400、502、503错误 [英] 400, 502, 503 errors with Websockets

问题描述

我正在使用Socket.io，Node.js和Openshift制作多人游戏.它工作了一段时间，但我做了一些小改动，但现在与我所做的更改无关的东西坏了.当第二位玩家尝试加入游戏时，它将引导所有人退出，对网站上的其他任何人都显示503错误.对于第二个玩家，我遇到了很多控制台错误，包括

I am making a multiplayer game using Socket.io, Node.js, and Openshift. It was working for a while, but I made a few small changes and now something unrelated to what I changed has broken. When a second player tries to join the game, it boots everyone out, showing a 503 error for anyone else who goes on the site. For the second player, I get a lot of console errors including

WebSocket connection to 'ws://avalon-evao.rhcloud.com/socket.io/?EIO=3&transport=websocket&sid=d5smykffy4EWHxgIAAAC' failed: Error during WebSocket handshake: Unexpected response code: 400

socket.io-1.2.0.js:2 WebSocket connection to 'ws://avalon-evao.rhcloud.com/socket.io/?EIO=3&transport=websocket&sid=c-fwcJaMkp_9rl5CAAAA' failed: WebSocket is closed before the connection is established.

它在localhost上运行正常，但实际站点已损坏.

It works perfectly fine in localhost, but the real site is broken.

这是我尝试过的:

1. 使用HTTPS.我仍然仍然会收到502错误.
2. 使用rhc app restart
重新启动应用
3. 使用rhc app force-stop rhc app start
重新启动应用
4. 检查内存限制.我还没打.
5. 使用{ secure: true }选项安全地连接到Websocket

1. Using HTTPS. I still somehow get the 502 error.
2. Restarting the app using rhc app restart
3. Restarting the app using rhc app force-stop rhc app start
4. Checking the memory limit. I haven't hit it.
5. Connecting to websockets securely using the { secure: true } option

是什么原因导致这些错误，我该如何解决?

What is causing these errors and how can I fix them?
