英文:
Websocket Failure on WriteMessage
问题
我正在使用Go语言构建一个简单的Slackbot作为学习经验，但我遇到了第一个问题：我无法向连接写入消息！
这是我的主要函数：
func main() {
conn, botId, err := slackInit(os.Getenv("SLACKBOT_TOKEN"))
if err != nil { return }
defer conn.Close()
for {
_, event, err := conn.ReadMessage()
if err != nil {
fmt.Println("Error processing message:", err)
return
}
fmt.Println(string(event))
message, err := slackGetMessage(event)
if strings.Contains(message, botId) {
fmt.Println("Bot was mentioned!")
resp := []byte("You talkin' to me?")
err = conn.WriteMessage(1, resp)
if err != nil {
fmt.Println("Error writing message:", string(resp))
return
}
}
}
}
这段代码可以监听并报告事件，但一旦调用conn.WriteMessage方法，就会失败。我从websocket得到一个致命错误，代码为1006，消息为"unexpected closure"。
我正在使用Gorilla作为我的websocket库，我怀疑这可能是与它们的"一个读者，一个写者"限制相关的并发问题。我尝试了一些调整，但实际上对于调试这个问题，我对这门语言/库还不够了解。:-/
我确定我在这里漏掉了一些明显的东西！有没有什么建议可以管理我的Writer，让我的机器人回应呢？谢谢！

I'm building out a simple Slackbot as a learning experience with Go, and I've hit my first snag: I'm unable to write a message back to the connection!
Here's my main func:
func main() {
conn, botId, err := slackInit(os.Getenv("SLACKBOT_TOKEN"))
if err != nil { return }
defer conn.Close()
for {
_, event, err := conn.ReadMessage()
if err != nil {
fmt.Println("Error processing message:", err)
return
}
fmt.Println(string(event))
message, err := slackGetMessage(event)
if strings.Contains(message, botId) {
fmt.Println("Bot was mentioned!")
resp := []byte("You talkin' to me?")
err = conn.WriteMessage(1, resp)
if err != nil {
fmt.Println("Error writing message:", string(resp))
return
}
}
}
}
This listens and reports events with no issue, but fails as soon as the conn.WriteMessage method is called. I get a fatal error from websocket with code 1006 & the message "unexpected closure".
I'm using Gorilla for my websocket library, and I suspect maybe this is a concurrency issue related to their "one reader, one writer" limit. I've tried a few tweaks, but honestly just don't know enough about the languge/library yet to really dive deep on debugging this. :-/
I'm sure I'm missing something obvious here! Any tips for managing my Writer to get my bot talking back? Thanks!

发送到服务器的消息不是服务器所期望的 JSON 格式。服务器在没有握手的情况下关闭了连接。
英文:
The message sent to the server is not JSON as expected by the server. The server closed the connection without a handshake.
