```go
package main

"io/ioutil"
"net/http"
)
func ParseReq(b []byte) (*http.Request, error) {

var buf io.ReadWriter

}
func main() {

req, err := ParseReq(context)
if err != nil {
fmt.Println("parse error, ", err)
}
fmt.Printf("req:---->%#v\n", req)
if req.Method == "POST" {
fmt.Println("URLEncoded form")
body, err := ioutil.ReadAll(req.Body)
if err != nil {
fmt.Println("readall error， ", err)
}
fmt.Println(string(body)) //why empty?
// err := req.ParseForm()
}
}
```
输出结果
```

URLEncoded form
```
不知道为何body为空，看了源码也不清楚，没看懂源码的Body是怎么赋值的
