Golang proper way to send json response with status
问题
如何在响应体中发送带有状态码的json响应。
我的代码
func getUser(w http.ResponseWriter, r *http.Request) {
w.Header().Set("Content-Type", "application/json")
var user []User
result := db.Find(&user)
response := map[string]interface{}{
"status": "success",
"statusCode": 200,
"data": result,
}
json.NewEncoder(w).Encode(response)
}
我的当前结果：
[
{
"name" : "test",
"age" : "28",
"email":"test@gmail.com"
},
{
"name" : "sss",
"age" : "60",
"email":"ss@gmail.com"
},
{
"name" : "ddd",
"age" : "30",
"email":"ddd@gmail.com"
},
]
但是我需要发送带有status码的响应，像这样：
{
"status" : "success",
"statusCode" : 200,
"data" : [
{
"name" : "test",
"age" : "28",
"email":"test@gmail.com"
},
{
"name" : "sss",
"age" : "60",
"email":"ss@gmail.com"
},
{
"name" : "ddd",
"age" : "30",
"email":"ddd@gmail.com"
},
]
}

How to send json response with status code in response body.
My code
func getUser(w http.ResponseWriter, r *http.Request) {
w.Header().Set("Content-Type", "application/json")
var user []User
result := db.Find(&user)
json.NewEncoder(w).Encode(result)
}
My result now:
[
{
"name" : "test",
"age" : "28",
"email":"test@gmail.com"
},
{
"name" : "sss",
"age" : "60",
"email":"ss@gmail.com"
},
{
"name" : "ddd",
"age" : "30",
"email":"ddd@gmail.com"
},
]
But I need to send the response with status code like this
{
status : "success",
statusCode : 200,
data : [
{
"name" : "test",
"age" : "28",
"email":"test@gmail.com"
},
{
"name" : "sss",
"age" : "60",
"email":"ss@gmail.com"
},
{
"name" : "ddd",
"age" : "30",
"email":"ddd@gmail.com"
},
]
}

如果你想要不同的 JSON，可以将不同的对象传递给 Encode 方法。
type Response struct {
Status string `json:"status"`
StatusCode int `json:"statusCode"`
Data []User `json:"data"`
}
func getUser(w http.ResponseWriter, r *http.Request) {
w.Header().Set("Content-Type", "application/json")
var user []User
result := db.Find(&user)
json.NewEncoder(w).Encode(&Response{"success", 200, result})
}
或者使用 map：
json.NewEncoder(w).Encode(map[string]interface{}{
"status": "success",
"statusCode": 200,
"data": result,
})
英文:
If you want different json, pass a different object to Encode.
type Response struct {
Status string `json:"status"`
StatucCode int `json:"statusCode"`
Data []User `json:"data"`
}
func getUser(w http.ResponseWriter, r *http.Request) {
w.Header().Set("Content-Type", "application/json")
var user []User
result := db.Find(&user)
json.NewEncoder(w).Encode(&Response{"success", 200, result})
}
Or use a map:
json.NewEncoder(w).Encode(map[string]interface{}{
"status": "success",
"statusCode": 200,
"data": result,
})
