本文只是模拟json序列化的过程

源码如下：

package mainimport "fmt"// JSONData is json obj
type JSONData struct {code    intmessage stringdata    []string
}// Phone struct is defined as pixel
type Phone struct {width  intheight int
}func tojson(code int, message string, screen Phone) (JSONData, error) {var obj JSONData obj.code = codeobj.message = messageobj.data = append(obj.data, fmt.Sprintf("{width:%d,height:%d}", screen.width, screen.height))return obj, nil
}func main() {obj, err := tojson(0, "hello woirld", Phone{100, 200})if err != nil {fmt.Printf("error")return}fmt.Printf(obj.data[0])
}

在vscode 执行结果如下：

API server listening at: 127.0.0.1:31242
{width:100,height:200}
Process exiting with code: 0
