我正在尝试获取 POST 请求中的参数,但我无法做到,我的代码是:
package main
import (
"fmt"
"log"
"net/http"
)
func main() {
http.HandleFunc("/", hello)
fmt.Printf("Starting server for testing HTTP POST...\n")
if err := http.ListenAndServe(":8080", nil); err != nil {
log.Fatal(err)
}
}
func hello(w http.ResponseWriter, r *http.Request) {
if r.URL.Path != "/" {
http.Error(w, "404 not found.", http.StatusNotFound)
return
}
switch r.Method {
case "POST":
// Call ParseForm() to parse the raw query and update r.PostForm and r.Form.
if err := r.ParseForm(); err != nil {
fmt.Fprintf(w, "ParseForm() err: %v", err)
return
}
name := r.Form.Get("name")
age := r.Form.Get("age")
fmt.Print("This have been received:")
fmt.Print("name: ", name)
fmt.Print("age: ", age)
default:
fmt.Fprintf(w, "Sorry, only POST methods are supported.")
}
}
我正在终端中发出 POST 请求,如下所示:
curl -X POST -d '{"name":"Alex","age":"50"}' localhost:8080
然后输出是:
This have been received:name: age:
为什么它不采用参数?我做错了什么?
