[英]Websocket Apache 2.4.x Proxy Tomcat 7.x open event happens only on browser side
我使用浏览器端的javascript和使用javax.websocket api编程的服务器端点编写了一个聊天应用程序。 我首先通过在浏览器和tomcat之间建立连接来测试应用程序,一切正常(操作系统是Windows 7)。
当我尝试使用apache 2.4.18服务器作为代理反向ssl时,似乎连接没有完全建立,我只在浏览器上获得onopen
事件。
我的tomcat日志告诉我,服务器端点实例也已创建,但onopen
事件不会发生在服务器端点实例上。 在我看来,服务器端点侦听错误的端口或类似的东西。
我在tomcat端使用ajp连接器。 我试图解决问题或了解它可能失败的地方,但没有成功。
这是我的代码片段:

通常在此之后,onopen事件发生在我的server-endpoint.class中并被记录,但这只有在我建立没有代理到tomcat的连接时才会发生...
这是我关于stackoverflow的第一个问题,所以如果我在订阅中忘记了一些重要信息,请耐心等待。 如果有人有建议会很好。 谢谢!
对于所有可能与同一主题斗争的人来说,经过大量的网站阅读和阅读后,我找到了一个解决方案,并将为所有感兴趣的人做出结论。
AJP-连接器:
AJP - tomcat 7的连接器没有! 支持websocket但它也没有给出任何日志或错误,请参阅: 1 : https: //mail-archives.apache.org/mod_mbox/tomcat-users/201408.mbo x/%3C53FF3A3A.3040507@christopherschultz.net %3E
所以对于websocket,我使用了https - 连接器,它已经附带了apache tomcat的server.xml:
<Connector port="8443" protocol="org.apache.coyote.http11.Http11Protocol"
maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
keystoreFile="E:\ssl\mykeystore" keystorePass="315225" keyPass="315225"
clientAuth="false" sslProtocol="TLS" />
我定义了一个关于bob文章的自签名证书: 在这里输入链接描述
我更改了httpd.conf中的端口以适应proxypass:
ProxyPass /myapp/chat wss://myhost:8443/myapp/chat
ProxyPassReverse /myapp/chat wss://myhost:8443/myapp/chat
ProxyPass /myapp/ https://myhost:8443/myapp/
ProxyPassReverse /myapp/ https://myhost:8443/myapp/
好吧,这是以tomcat的自签名证书导致的代理错误结束的。 对于测试和开发,您可以在httpd.conf中使用一些额外的行来避免这种情况:
<IfModule ssl_module>
SSLRandomSeed startup builtin
SSLRandomSeed connect builtin
SSLProxyEngine on
SSLProxyVerify none
SSLProxyCheckPeerCN off
SSLProxyCheckPeerName off
SSLProxyCheckPeerExpire off
</IfModule>
我要解决的最后一件事是在我的pom.xml中为websocket选择正确的依赖关系,取决于tomcat-version,它可以在maven-repository上找到: 在这里输入链接描述 ,应该如下所示:
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-websocket</artifactId>
<version>7.0.64</version>
</dependency>
不要使用javax.websocket依赖项,即使使用
<scope>provided</scope>
属性它也不适用于我(也许我做错了什么或忘记了什么)希望这有效并帮助你们:-)
在代理设置中添加/到wss的末尾
ProxyPass /myapp/chat/ wss://x:443/myapp/chat/
ProxyPassReverse /myapp/chat/ wss://x:443/myapp/chat/
