带有apache代理的Socket.io
即时尝试设置与Apache的proxyng能够在我的nodejs应用程序中使用socket.io。 但我在客户端收到这个错误信息：
WebSocket connection to 'wss://example.com/tools/socket.io/?EIO=3&transport=websocket&sid=eOGwJSC14TTWhHRMAAAR' failed: Error during WebSocket handshake: Unexpected response code: 400
下面是我的Apache配置：
<VirtualHost *:443>
ServerName example.com
ServerAlias example.com
#SSLRequireSSL
SSLProtocol all -SSLv2 -SSLv3
SSLCompression off
SSLHonorCipherOrder on
SSLEngine on
SSLCertificateFile /etc/ssl/main.pem
SSLCertificateKeyFile /etc/ssl/dec_ssl.key
SSLCertificateChainFile /etc/ssl/sub.class1.server.ca.pem
SSLCACertificateFile /etc/ssl/main.pem
SSLProxyEngine On
ProxyPreserveHost On
ProxyRequests off
</VirtualHost>
<Location /tools/>
ProxyPass http://localhost:8181/
ProxyPassReverse http://localhost:8181/
</Location>
这里是客户端代码：
socket = io.connect("https://example.com",{path:'/tools/socket.io'});
socket.on("connect", function () {
console.log("socketio Connected to server!");
});
还有什么我需要添加到Apache配置摆脱这个错误？
编辑：我的apache版本：服务器版本：Apache / 2.4.6（CentOS）
我已经成功地使用了Apache 2.4.16，旧版本可能无法正常工作。
<VirtualHost *:443>
ServerName example.com
ServerAlias example.com
#SSLRequireSSL
SSLProtocol all -SSLv2 -SSLv3
SSLCompression off
SSLHonorCipherOrder on
SSLEngine on
SSLCertificateFile /etc/ssl/main.pem
SSLCertificateKeyFile /etc/ssl/dec_ssl.key
SSLCertificateChainFile /etc/ssl/sub.class1.server.ca.pem
SSLCACertificateFile /etc/ssl/main.pem
SSLProxyEngine On
ProxyPreserveHost On
ProxyRequests off
</VirtualHost>
<Location /tools/>
RewriteEngine On
RewriteCond %{REQUEST_URI} ^/tools/socket.io [NC]
RewriteCond %{QUERY_STRING} transport=websocket [NC]
RewriteRule "^/tools/socket.io" "ws://localhost:8181/socket.io/" [P,L]
ProxyPass http://localhost:8181/
ProxyPassReverse http://localhost:8181/
</Location>
ProxyPass不会处理websocket升级。 所以，你想要做的是将这些请求重定向到ws：//
我认为一般来说你不应该使用Location来处理这个问题，但是这个配置应该适合你。
根据@Gary，我添加了以下内容
<Location /tools/>
RewriteEngine On
RewriteCond %{REQUEST_URI} ^/tools/socket.io [NC]
RewriteCond %{QUERY_STRING} transport=websocket [NC]
RewriteRule "/(.*)" "ws://localhost:8181/socket.io/" [P,L]
ProxyPass http://localhost:8181/
ProxyPassReverse http://localhost:8181/
</Location>
并使用路径属性从客户端连接套接字。
discussionSocket = io("https://localhost.in", {
path:'/tools/socket.io',
secure: true,
reconnection: true,
reconnectionDelay: 1000,
reconnectionDelayMax: 5000,
reconnectionAttempts: 99999
});
但为此，我们必须从套接字服务器删除ssl配置创建代码： -
var http = require('http').Server(app);
