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使用 javax.websocket API 编程的端点。我首先测试了该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(操作系统是Windows 7(。
当我尝试使用 apache 2.4.18 服务器作为 SSL 上的代理反向时,似乎连接没有完全建立,我只在浏览器上得到一个onopen
事件。
我的 tomcat 日志告诉我,服务器终端节点实例也已创建,但服务器终端节点实例上不会发生onopen
事件。在我看来,服务器端点侦听了错误的端口或类似的东西。
我在雄猫侧使用 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。
以下是我的代码片段:

通常在那之后,onopen 事件发生在我的服务器端点中.class并被记录下来,但这只有在我没有代理 tomcat 的情况下建立连接时才会发生......
这是我关于stackoverflow的第一个问题,所以如果我忘记了订阅中的一些重要信息,请耐心等待。愿意如果有人有建议,那就很好。感谢!
对于所有可能在同一主题上挣扎的人,经过大量的网站获取和阅读,我找到了一个解决方案,并将为所有感兴趣的人得出结论。
AJP 连接器:
AJP - Tomcat 7 的连接器不支持 websocket,但它也支持 websocket 不会给出任何日志或错误,另请参阅以下内容: 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,它已经随服务器一起提供.xml apache tomcat:
<Connector port="8443" protocol="org.apache.coyote.http11.Http11Protocol"
maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
keystoreFile="E:sslmykeystore" keystorePass="315225" keyPass="315225"
clientAuth="false" sslProtocol="TLS" />
我定义了一个关于鲍勃文章的自签名证书:在此处输入链接描述
> httdp.conf
我更改了 httpd.conf 中的端口以适应代理通行证:
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,这以由 雄猫的自签名证书。对于测试和开发您 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中选择正确的依赖项.xml对于websocket,根据tomcat版本,它可以在maven-repository上找到:在此处输入链接描述,应如下所示:
<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>
属性它对我不起作用(也许我确实这样做了 有些不对劲或忘记了什么(希望这有效并帮助您:-(
在代理设置中将/添加到 WSS 的末尾
ProxyPass /myapp/chat/ wss://x:443/myapp/chat/
ProxyPassReverse /myapp/chat/ wss://x:443/myapp/chat/
