我遵循了此处提供的用户指南:我在我的 pom 中添加了这个:
<dependency>
<groupId>org.glassfish.tyrus</groupId>
<artifactId>tyrus-server</artifactId>
<version>1.2</version>
</dependency>
<dependency>
<groupId>org.glassfish.tyrus</groupId>
<artifactId>tyrus-container-grizzly</artifactId>
<version>1.2</version>
</dependency>
我在我的主课上写了这个:
Server server = new Server("localhost", 8624, "/", EchoEndPoint.class);
try
{
server.start();
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
System.out.print("Please press a key to stop the server.");
reader.readLine();
}
catch(Exception ex) { ex.printStackTrace(); }
finally
{
server.stop();
}
我的 EchoEndPoint 类的内容与指南中描述的相同。
我尝试使用 HTML5 websocket 连接到它:
var ws = new WebSocket("ws://localhost:8624/echo");
看来,浏览器端,它没有连接(它直接调用 onClose 回调)。而且,服务器端,我在控制台中得到了这个:
Grave: Invalid Connection header returned: 'keep-alive'

如果有任何帮助,我复制浏览器检查器捕获的请求标头:

这是握手问题吗?
编辑:我已经在 Chrome (28.0.1500.72) 中尝试过,它正在工作。也许问题来自 Firefox 在构建标头时?
