### 原理
|
||
|
|
- 结构体实现ServeHTTP(http.ResponseWriter, *http.Request)方法
|
||
|
|
|
||
|
|
### 代码
|
||
|
|
```go
|
||
|
|
package main
|
||
|
|
|
||
|
|
import (
|
||
|
|
"fmt"
|
||
|
|
"io/ioutil"
|
||
|
|
"net/http"
|
||
|
|
)
|
||
|
|
|
||
|
|
type Handler struct{}
|
||
|
|
|
||
|
|
func (h *Handler) ServeHTTP(w http.ResponseWriter, req *http.Request) {
|
||
|
|
requestBody, err := ioutil.ReadAll(req.Body)
|
||
|
|
if err != nil {
|
||
|
|
w.Write([]byte(err.Error()))
|
||
|
|
return
|
||
|
|
}
|
||
|
|
fmt.Println(req.RequestURI)
|
||
|
|
fmt.Println(string(requestBody))
|
||
|
|
}
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
server := http.Server{Addr: ":8081", Handler: &Handler{}}
|
||
|
|
err := server.ListenAndServe()
|
||
|
|
if err != nil {
|
||
|
|
fmt.Println(err.Error())
|
||
|
|
}
|
||
|
|
}
|
||
|
|
|
||
|
|
```
