将Apache服务器与Engintron结合使用,并且我正在运行一个expressJS应用程序,该应用程序接受socket.io连接以处理websocket调用。
但是,每当主站点(使用PHP)尝试调用nodeJS应用程序时,握手时都会返回错误400,并回退到长时间轮询。
答案 0 :(得分:1)
因为我花了很多时间弄清楚它是如何工作的,所以我认为我将在此处同时张贴问题和答案,因此其他人或我未来的自己将不必在此花费很多时间,因为互联网上没有太多信息。
所有答案都指向我启用mod_proxy_wstunnel,但是实际上这并不是我的实际问题。当我禁用Engintron并发现它开始工作时,我意识到了这一点。
因此,您需要做的是访问Engintron,转到Edit proxy_params_common
,并确保它看起来像这样:
