我剛剛嘗試過,它似乎工作。

你會有一個破碎的代碼樣本?

簡單的例子:(https://play.golang.org/p/xg8lGNofze

package main 

import (
    "encoding/json" 
    "log" 
    "net/http" 
) 

func testHdlr(w http.ResponseWriter, req *http.Request) { 
    m := map[string]string{ 
     "foo": "bar", 
    } 
    w.Header().Add("Content-Type", "application/json") 
    w.WriteHeader(http.StatusCreated) 
    _ = json.NewEncoder(w).Encode(m) 
} 

func main() { 
    http.HandleFunc("/", testHdlr) 
    log.Fatal(http.ListenAndServe(":8080", nil)) 
} 

然後

$> curl -v http://localhost:8080 
[...]
