Websocket Apache 2.4.x代理Tomcat 7.x open事件仅在浏览器端发生

标签: java apache tomcat websocket java-websocket

我在浏览器端和服务器上使用javascript编写了一个聊天应用程序 用javax.websocket api编写的端点。我首先测试了应用程序 通过建立浏览器和tomcat之间的连接和一切 工作正常(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,我只在浏览器上收到onopen事件。
我的tomcat日志告诉我,服务器端点实例也已创建,但onopen事件并未在服务器端点实例上发生。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。

以下是我的代码段:

通常在此之后,onopen事件发生在我的server-endpoint.class中并被记录,但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。将 如果有人有建议,那就好了。 THX!

对于所有可能与同一主题斗争的人, 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

因此对于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:enter link description here

&GT; httdp.conf

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,这是以一个代理错误结束的   tomcat的自签名证书。用于测试和开发你   可以通过httpd.conf中的一些额外行来避免这种情况:

<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选择正确的依赖项,具体取决于tomcat-version,它可以在maven-repository:enter link description here上找到,应该看看像这样:

<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,即使使用了   <scope>provided</scope>属性它对我不起作用(也许我做过   有些不对劲或遗忘了什么)

     

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/
