我正在尝试使用websockets连接Primus:
WebSocket connection to 'wss://dev.dylaan.nl/primus/?_primuscb=1417355606238-6' failed: WebSocket opening handshake was canceled
我的NodeJS脚本:
var express = require("express")
, fs = require("fs")
, path = require("path")
, moment = require("moment")
, Primus = require("primus")
, compression = require("compression")
, app = express()
, http = require("http").createServer(app)
, jsp = require("uglify-js").parser
, pro = require("uglify-js").uglify
, primus = new Primus(http, { transformer: "websockets" });
客户端:
var primus = new Primus("wss://dev.dylaan.nl")
我对这种东西不熟悉,但我现在不知道什么是错的,我已经阅读了Primus的文档,我也试过谷歌,但我可以找到答案。
当我将协议更改为ws
而不是wss
时,我收到错误
Error during WebSocket handshake: Unexpected response code: 426
http 426 may mean that you are trying to connect with an unsupported websocket protocol version
Also, if you are connecting through a proxy, the proxy may remove the "upgrade" header from the request since it is marked as "connection" header. Switch to WSS:// to prevent that.
@ Unexpected response code: 426 with PhanthomJS Websocket client/ROSLIB
好吧,我的VPS支持ngnix反向代理。我无法访问那些。这就是为什么我使用wss。
有人可以帮忙吗?
谢谢!
答案 0 :(得分:0)
在我看来,您已经错误地配置了nginx服务器并且它阻止了WebSocket连接,导致返回400错误。请参阅http://nginx.com/blog/websocket-nginx/,了解如何配置服务器以允许websocket连接。
如果您无法让主机/ vps验证是否允许连接WebSocket,则可以通过在客户端代码中提供选项{ websocket: false }
来完全关闭Primus中的WebSockets:
new Primus("http://dev.dylaan.nl", { websocket: false })
我还注意到您使用了wss/ws
而不是Primus要求的http
,我们会自动将基于HTTP的网址重写为正确的格式。
