在Go语言中,可以使用标准库encoding/json将结构体(struct)转换为JSON格式的数据。 具体步骤如下: 导入必要的包: go import ( "encoding/json" "fmt" ) 定义结构体: go type Person struct { Name string `json:"name"` Age int `json:"age"` } 创建结构体实例: g
StaticFileVersion int `json:"static_file_version"` StaticDir string `json:"static_dir"` TemplatesDir string `json:"templates_dir"` SerTcpSocketHost string `json:"serTcpSocketHost"` SerTcpSocketPort int `json:"serTcpSocketPort"` Fruits []string `json:"fruits"` } type Other struct { SerT...
Id string `json:"id"` UserName string `json:"user_name"` Address []AddressVo `json:"address"` } type AddressVo struct { Address string `json:"address"` } var beforeMap = map[string]interface{}{ "id": "123", "user_name": "酒窝猪", "address": []map[string]interface{}{{"addre...

<1. 使用 json.Unmarshal 时,结构体的每一项必须是导出项(import field)。也就是说结构体的 key 对应的首字母必须为大写。请看下面的例子: package commontest import ( "testing" "encoding/json" ) type Person struct { name string age int
type People3 struct { Namestring`json:"name"` Ageint`json:"age"` }//go get github.com/goinggo/mapstructurefunc main() { mapInstance :=make(map[string]interface{}) mapInstance["Name"] ="张三"mapInstance["Age"] =18var people People3 ...

package main import ( "encoding/json" "fmt" ) //把结构体都改小写 type User struct { UserName string `json:"user_name"` //json的tag标记 Nickname string `json:"nickname"` Age int Birthday string Sex string Email string Phone string } func testStruct() { user1 := &User{ UserName: "...
