先将map转换成JSON,再通过 JSON 转换成struct 操作有点繁琐 funcTestMapToStructByJson(t*testing.T){ beforeMap:=map[string]interface{}{ "id":"123", "user_name":"酒窝猪", "address":[]map[string]interface{}{{"address":"address01"},{"address":"address02"}}, } varafterStruct=UserInfoVo{...

fmt.Println(mapResult) } AI代码助手复制代码 输出: (2)map转Json例子 funcMapToJsonDemo1(){ mapInstances := []map[string]interface{}{} instance_1 :=map[string]interface{}{"name":"John","age":10} instance_2 :=map[string]interface{}{"name":"Alex","age":12} mapInstances =append(map...
三、map和struct互转 (1)map转struct 需要安装一个第三方库在命令行中运行: go get github.com/goinggo/mapstructure例子: 1 2 3 4 5 6 7 8 9 10 11 12 func MapToStructDemo() { mapInstance := make(map[string]interface{}) mapInstance["Name"] = "jqw" mapInstance["Age"] = 18 var peop...

迭代中修改 map:在使用 range 迭代 map 时,如果在迭代过程中对 map 进行了修改(添加、删除元素),可能会导致迭代器失效、也会产生不确定的结果。 遍历顺序不确定性:map 的迭代顺序是不确定的,每次遍历的结果可能不同。 零值问题:对值为 nil 的 map 操作,如果操作不当会造成程序 Panic。
