web框架中的每个请求是一个gorutine吗？

```go package main import "net/http" func main() { c := make(chan string) http.HandleFunc("/get", func(w http.ResponseWriter, r *http.Request) { msg,_ := <- c w.Write([]byte(msg)) }) http.HandleFunc("/post", func(w http.ResponseWriter, r *http.Request) { c <- "world" w.Write([]byte(" world!")) }) http.ListenAndServe("localhost:3000", nil) } ``` 期望 curl http://localhost:3000/post 写channel curl http://localhost:3000/get 读channel 但是一运行就死锁了
