Websocket Apache 2.4.x 代理 Tomcat 7.x 打开事件只发生在浏览器端

Question

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 编程的端点。我首先测试了应用程序通过在浏览器和 tomcat 以及所有内容之间建立连接工作正常（OS 是 Windows 7）。

当我尝试使用 apache 2.4.18 服务器作为 ssl 反向代理时，似乎连接没有完全建立，我只在浏览器上收到一个 onopen 事件。
我的 tomcat 日志告诉我，服务器端点实例也已创建，但 onopen 事件不会在服务器端点实例上发生。在我看来，服务器端点侦听了错误的端口或类似的东西。

我在 tomcat 端使用了一个 ajp 连接器。我试图解决问题或了解可能会失败的地方，但没有成功。

这是我的代码片段：

通常在那之后，onopen 事件发生在我的服务器 - endpoint.class 中并被记录下来，但这只有在我建立连接而不使用代理到 tomcat...[=19= 时才会发生]

这是我关于 Whosebug 的第一个问题，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，那就太好了。谢谢！

Answer 1

在您的代理设置中将 / 添加到 wss 的末尾

ProxyPass /myapp/chat/ wss://x:443/myapp/chat/
ProxyPassReverse /myapp/chat/ wss://x:443/myapp/chat/

Answer 2

对于所有可能为同一主题而苦恼的人，经过大量浏览网站和阅读，我找到了解决方案，并将为所有感兴趣的人做出结论。

AJP-Connector:

AJP - connector of tomcat 7 does not! support websocket but it also does not give any logs or errors, see also this: 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，它已经随 apache server.xml tomcat:

<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" />

I defined a selfsigned certificate regarding to the article of bob: enter link description here

> 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/

Well, this was ending in an Proxy-Error caused by the self-signed-certificate of the tomcat. For testing and development you can avoid this with a few additional rows in the httpd.conf:

<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 版本，它可以在 maven-repository 上找到： enter link description here 应该是这样的：

<dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-websocket</artifactId>
    <version>7.0.64</version>
</dependency>

Don't use the javax.websocket dependency, even with the <scope>provided</scope> attribute it didn't work for me (maybe i did something wrong or forgot something)

Hope this works and helps you guys:-)
