如果解析json时,把json解析到map[string]interface ,那值所对应的真正类型是下面这样的
bool,for JSON booleans
float64,for JSON numbers
string,for JSON strings
[]interface{},for JSON arrays
map[string]interface{},for JSON objects
nil for JSON null
json中的数值类型,会是float64类型
json对象会解析成,map[string]interface
代码可以这样写:
func send(w http.ResponseWriter,r *http.Request){ w.Header().Set("content-type",text/json;charset=utf-8;") var sendData map[string]interface{} bodyBytes,err:=IoUtil.ReadAll(r.Body) if err!=nil{ msg,_ := json.Marshal(tools.JsonResult{Code: 400,Msg: 操作失败,"+err.Error()}) w.Write(msg) return } err = json.Unmarshal(bodyBytes,&sendData) } smtpServer:=sendData[smtp"].(string) smtpFrom:=sendData[from) msg,_ := json.Marshal(tools.JsonResult{Code: 200,Msg: smtpServer+smtpFrom}) w.Write(msg) }
