How to convert structure into json string in go language
This article mainly introduces "go language how to convert structure into json string". In daily operation, I believe many people have doubts about how to convert structure into json string in go language. Xiaobian consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the question of "how to convert structure into json string in go language". Next, please follow the editor to study!
1. Since you are converting a structure into a json string, define a structure first
The copy code is as follows:
/ / define a structure
Type NewsModel struct {
Id int
Title string
}
2. Let's see what method the ffjson package uses to convert the structure into a json string
The copy code is as follows:
Func main () {
News: = NewsModel {110, "hello"}
Res,err: = ffjson.Marshal (news)
If err! = nil {
Fmt.Println ("format error")
Fmt.Println (err.Error ())
Return
}
/ / it is a byte array, so it is also converted to string.
Fmt.Println (string (res))
}
Print:
{"Id": 110," Title ":" hello "}
Get a json string
3. Expansion
Encapsulate a method ToJson () for the structure specifically to do this
The copy code is as follows:
Package main
Import (
"fmt"
"github.com/pquerna/ffjson/ffjson"
)
/ / define a structure
Type NewsModel struct {
Id int
Title string
}
/ / define a method
Func (news NewsModel) ToJson () string {
Res,err: = ffjson.Marshal (news)
If err! = nil {
Return err.Error ()
}
/ / it is a byte array, so it is also converted to string.
Return string (res)
}
Func main () {
News: = NewsModel {110, "hello"}
Fmt.Println (news.ToJson ()) / / print: {"Id": 110, "Title": "hello"}
}
