如何在响应正文中包含JSON对象时将响应状态代码设置为201?我似乎无法同时执行这两个 - 要么我返回带有消息体的200,要么返回没有消息体的201.
答案 0 :(得分:2)
我刚试过,似乎有效。
您是否有破损代码的样本?
简单示例:(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))
}
然后
$> curl -v http://localhost:8080
[...]
< HTTP/1.1 201 Created
