Golang Changing HTTP Response Status Code 201 with Body in the Response
问题
你好！要同时设置响应状态码为201并在响应体中包含JSON对象，你可以按照以下步骤进行操作：
- 首先，确保你的开发环境支持操作HTTP响应。
- 创建一个包含你要返回的JSON对象的变量。
- 设置响应状态码为201。
- 将JSON对象转换为字符串格式。
- 将字符串作为响应体返回。
以下是一个示例代码片段，展示了如何实现上述步骤：
import json
# 创建要返回的JSON对象
response_data = {
"message": "Success",
"data": {
"key": "value"
}
}
# 设置响应状态码为201
response_status_code = 201
# 将JSON对象转换为字符串
response_body = json.dumps(response_data)
# 返回响应
return response_status_code, response_body
请根据你的具体开发环境和需求进行相应的调整。希望对你有帮助！
英文:
How do I set the response status code to 201 while including a JSON object in the response body? I can't seem to perform both of these at once -- either I return a 200 with a message body, or a 201 without one.

我刚刚尝试了一下，似乎可以工作。
你有一段错误的代码示例吗？
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))
}
然后执行：
$> curl -v http://localhost:8080
[...]
< HTTP/1.1 201 Created
< Date: Thu, 25 May 2017 00:54:15 GMT
< Content-Length: 14
< Content-Type: application/json

{ [14 bytes data]
* Curl_http_done: called premature == 0
100 14 100 14 0 0 2831 0 --:--:-- --:--:-- --:--:-- 3500
* Connection #0 to host localhost left intact
{"foo":"bar"}

I just tried and it seems to work.
Would you have a sample of broken code?
Simple example: (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))
}
Then
$> curl -v http://localhost:8080
[...]
< HTTP/1.1 201 Created
< Date: Thu, 25 May 2017 00:54:15 GMT
< Content-Length: 14
< Content-Type: application/json
<
{ [14 bytes data]
* Curl_http_done: called premature == 0
100 14 100 14 0 0 2831 0 --:--:-- --:--:-- --:--:-- 3500
* Connection #0 to host localhost left intact
{"foo":"bar"}
