Gorilla Websocket:Websocket握手时出错：意外响应代码：404

我克隆了gorilla websocket聊天示例，并将其更新为使用多个聊天室。但是，我得到了一个错误： WebSocket握手时出错：意外响应代码：404 在chrome中，每当我尝试建立连接时。我的源代码可以在上找到。它与原来的示例非常相似，只是做了轻微的更改。我不知道为什么它不起作用

编辑： 此代码行中出现问题：

for _, name := range []string{"arduino", "java", "go", "scala"} {
    room := newRoom("go")
    http.Handle("/chat/go", room)
    go room.run()
}

在片上循环会导致httphandle函数出现问题。如果相反，我单独声明：

room := newRoom("go")
http.Handle("/chat/go", room)
go room.run()
...

它起作用了。如何修复此问题？

因此，实际上从

index.html

文件中，您连接到了错误的url

<!-- index.html -->
<script>
    var serviceLocation = "ws://0.0.0.0:8080/chat/";
.....

    function connectToChatserver() {
        room = $('#chatroom option:selected').val();
        wsocket = new WebSocket(serviceLocation + room);
        // it connect to /chat/<room>, it has slash after chat

它将使url如下所示：http://localhost:8080/chatgo，而不是您想要的：http://localhost:8080/chat/go

仅供参考，它将出错，因为您没有正确处理

，因此在我发送1条消息后，它将自动关闭。但这是另一个话题

嗨，我已经检查过你的代码了。你的操作系统和你的Golang版本是什么？@FahimBagar我想你搞错链接了。这是下分店的“房间”谢谢！这就解决了问题。我知道这是一件很愚蠢的事：）。我修复了通道关闭错误。谢谢
