[Go]当把json解析到interface{}时 , 对应的真正类型

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)
}
