func main(){
var flagtext = flag.String("flagtext", "Hello!", "Flag")
flag.Parse()
var text string
text = *flagtext
m := Message{text}
var m1 Message
b, err := json.Marshal(m)
if err == nil{
resp, err := http.Post("http://127.0.0.1:8080","application/json", strings.NewReader(string(b)))
if err != nil{
log.Fatal("Error while post: %v",err)
}
fmt.Println(resp)
err = json.Unmarshal(b, &m1)
}
}
运行 client.go 时出现的错误是:
Error while post: %vmalformed HTTP status code "/"
虽然服务器为每个帖子注册了一个频道,但它显示了一个格式错误的 HTTP 状态代码。是不是因为我听错频道了?我很困惑为什么会发生这个错误。
