//TypeOf returns the reflection Type of the value in the interface{}.func TypeOf(iinterface{}) Type 也就是说TypeOf会用interface{}把参数储存起来,然后reflect.TypeOf再从interface{}中获取信息。 同理ValueOf的函数定义为: //ValueOf returns a new Value initialized to the concrete value//stored i...
如果输入是 JSON 字符串,我们首先将其解析为map[string]interface{}格式,然后将其映射到结构中。 func jsonDecode() { var jsonStr = `{ "name": "Foo", "age": 21, "gender": "male" }` type Person struct { Name string Age int Gender string } m := make(map[string]interface{}) err :=...

上面的代码中,我们定义了一个名为infoMap的map类型,并初始化了其内部的数据。我们将map的键设置为string类型,值则设为interface{}类型,以便存储一个任意类型的数据。 接下来,我们使用"encoding/json"包中的Marshal方法将map数据转化为JSON格式字符串。 //将map数据转化为JSON格式字符串jsonBytes, err := json.Mars...
beforeMap := map[string]interface {}{ "id":"123", "user_name":"酒窝猪", "address":[]map[string]interface{}{{"address": "address01"}, {"address": "address02"}}, } var afterStruct =UserInfoVo{} before := time.Now() marshal, err := json.Marshal(beforeMap) ...
golang中map结构转换成json package main import ( "encoding/json" "fmt" ) func main() { m := make(map[string]interface{}, 4) m["name"] = "wilson" m["lang"] = []string{"go", "python", "java"} m["isok"] = true m["price"] = 5.55...
1. 空interface赋值 先看如下代码: packagemainimport("fmt""reflect")funcmain(){varIinterface{}I=1fmt.Println(reflect.TypeOf(I).Kind().String())I=1.3fmt.Println(reflect.TypeOf(I).Kind().String())I=truefmt.Println(reflect.TypeOf(I).Kind().String())I=map[string]int{"age":21,}fmt....
先将map 转换成 JSON,再通过 JSON 转换成 struct 操作有点繁琐 func TestMapToStructByJson(t *testing.T) { beforeMap := map[string]interface {}{ "id":"123", "user_name":"酒窝猪", "address":[]map[string]interface{}{{"address": "address01"}, {"address": "address02"}}, } var af...
四.json转map,数字默认为float64 package main import("encoding/json""fmt")funcmain(){mJson:=`{"age":11,"gender":77,"name":"HanMeimei","subject":["语文","数学","英语"]}` m:=make(map[string]interface{})json.Unmarshal([]byte(mJson),&m)fmt.Println(m)//类型断言forkey,value:=rang...
