tostruct

json/yaml/http header/query string 转成 struct 定义，免去手写 struct 的烦恼.

一、json 字符串生成结构体

import (
    "github.com/antlabs/tostruct/json"
    "github.com/antlabs/tostruct/option"
)
func main() {
var str = { 	"action": "Deactivate user", 	"entities": [ 		{ 		"uuid": "4759aa70-XXXX-XXXX-925f-6fa0510823ba", 		"type": "user", 		"created": 1542595573399, 		"modified": 1542597578147, 		"username": "user1", 		"activated": false, 		"nickname": "user" 		}], 		"timestamp": 1542602157258, 		"duration": 12 	}
// 父子结构合在一起
all, _ := json.Marshal([]byte(str), option.WithStructName("reqName"))
fmt.Println(string(all))
/*
type reqName struct {
	Action   string `json:"action"`
	Duration int    `json:"duration"`
	Entities []struct {
		Activated bool   `json:"activated"`
		Created   int    `json:"created"`
		Modified  int    `json:"modified"`
		Nickname  string `json:"nickname"`
		Type      string `json:"type"`
		Username  string `json:"username"`
		UUID      string `json:"uuid"`
	} `json:"entities"`
	Timestamp int `json:"timestamp"`
}
*/

// 子结构拆分
all, _ := json.Marshal([]byte(str), option.WithStructName("reqName"), option.WithNotInline())
fmt.Println(string(all))
/*
type reqName struct {
	Action    string     `json:"action"`
	Duration  int        `json:"duration"`
	Entities  []Entities `json:"entities"`
	Timestamp int        `json:"timestamp"`
}

type Entities struct {
	Activated bool   `json:"activated"`
	Created   int    `json:"created"`
	Modified  int    `json:"modified"`
	Nickname  string `json:"nickname"`
	Type      string `json:"type"`
	Username  string `json:"username"`
	UUID      string `json:"uuid"`
}
*/
}

二、http header 生成结构体

import (
    "github.com/antlabs/tostruct/header"
    "github.com/antlabs/tostruct/option"
	"net/http"
)
func main() {
h := http.header{
“bool”: []string{“true”},
“int” : []string{“1”},
“string” : []string{“hello”},
“float64” : []string{“3.14”},
}
res, err := header.Marshal(h, option.WithStructName(“test”), option.WithTagName(“header”))
if err != nil {
fmt.Println(err.Error())
return
}
fmt.Println(string(res))
/*
type test struct {
Bool    bool    header:"bool"
Float64 float64 header:"float64"
Int     int     header:"int"
String  string  header:"string"
}
*/
}

三、查询字符串生成结构体

import (
    "github.com/antlabs/tostruct/url"
    "github.com/antlabs/tostruct/option"
)
func main() {
url := “http://127.0.0.1:8080?int=1&float64=1.1&bool=true&string=hello”
res, err := header.Marshal(h, option.WithStructName(“test”), option.WithTagName(“form”))
if err != nil {
fmt.Println(err.Error())
return
}
fmt.Println(string(res))
/*
type test struct {
Bool    bool    form:"bool"
Float64 float64 form:"float64"
Int     int     form:"int"
String  string  form:"string"
}
*/
}

四、yaml 生成结构体

import (
    "github.com/antlabs/tostruct/url"
    "github.com/antlabs/tostruct/option"
	"github.com/antlabs/tostruct/yaml"
)
func main() {
str := `
a: 1
b: 3.14
c: hello
d:


aa


bb
e:


a: 1
b: 3.14
c: hello
f:
first: 1
second: 3.14
`
all, err := Marshal([]byte(str), option.WithStructName(“reqName”))
if err != nil {
return
}
fmt.Println(all)
/*
type reqName struct {
A int      yaml:"a"
B float64  yaml:"b"
C string   yaml:"c"
D []string yaml:"d"
E []struct {
A int     yaml:"a"
B float64 yaml:"b"
C string  yaml:"c"
} yaml:"e"
F struct {
First  int     yaml:"first"
Second float64 yaml:"second"
} yaml:"f"
}
*/
all, err := Marshal([]byte(str), option.WithStructName(“reqName”), option.WithNotInline())
if err != nil {
return
}
fmt.Println(all)
/*
type reqName struct {
A int      yaml:"a"
B float64  yaml:"b"
C string   yaml:"c"
D []string yaml:"d"
E []E      yaml:"e"
F F        yaml:"f"
}


type E struct {
A int     yaml:"a"
B float64 yaml:"b"
C string  yaml:"c"
}
type F struct {
First  int     yaml:"first"
Second float64 yaml:"second"
}
*/
}
