A packet of Golang parsing JSON data written in Golang

This is a creation in Article, where the information may have evolved or changed.

Gojson is a Golang package that quickly parses JSON data, which you can use to quickly find data in JSON

Installation

 go get github.com/widuu/gojson

Introduction to use

Structure

type Js struct {    data interface{}}

(1) func Json(data) *Js data is a string type, initializes the JS structure, parses the JSON and returnJs.data

json := `{"from":"en","to":"zh"}`c1 := gojson.Json(json) //&{map[from:en to:zh]}

(2) func (*Js) Get() *js get a value from a simple JSON, recursively find, returnJs.data

json := `{"from":"en","to":"zh","trans_result":{"src":"today","dst":"\u4eca\u5929"},"result":["src","today","dst","\u4eca\u5929"]}`c2 := gojson.Json(json).Get("trans_result").Get("dst")fmt.Println(c2) //&{今天}c2 := gojson.Json(json).Get("from")fmt.Println(c2) //&{en}

(3) Convert func (*Js)Tostring()string a single data to a string type, because the string type is better when other types are improved let the data return a string

c2 := gojson.Json(json).Get("from").Tostring()fmt.Println(c2) //en

(4) func (j *Js) Getpath(args ...string) *Js by entering multiple parameters of string to get a value, the JSON data must be recursive

c4 := gojson.Json(json).Getpath("trans_result", "src").Tostring()fmt.Println(c4)  //today

(5) func (j *Js) Arrayindex(i int) string Gets the value of the array structure in the JSON data, returns the corresponding value according to the input num, and is limited to processing {"Result": ["src", "Today", "DST", "\u4eca\u5929″]} [] values within []

json := `{"from":"en","to":"zh","trans_result":{"src":"today","dst":"\u4eca\u5929"},"result":["src","today","dst","\u4eca\u5929"]}`c7 := gojson.Json(json).Get("result").Arrayindex(1)fmt.Println(c7) //src

(6) func (j *Js) Getkey(key string, i int) *Js This function is for data to have duplicate data, value, use js.data must be []interface{} type, this is Baidu translation when the return JS may use

json1 := `{"from":"en","to":"zh","trans_result":[{"src":"today","dst":"\u4eca\u5929"},{"src":"tomorrow","dst":"\u660e\u5929"}]}`c8 := gojson.Json(json1).Get("trans_result").Getkey("src", 1).Tostring()fmt.Println(c8) //则返回trans_result第一组中的src today

(7) func (j *Js) ToArray() (k, d []string) convert the JSON data to a key []string{} value []string{} one by one corresponding to the array, can only use to two levels can not go to the multilevel

c9k, c9v := gojson.Json(json1).Get("trans_result").ToArray()fmt.Println(c9k, c9v) //[src dst src dst] [today 今天 tomorrow 明天]c3k, c3v := gojson.Json(json).Getindex(1).ToArray()fmt.Println(c3k, c3v) //    [from] [en]

(8) func (j *Js) Getindex(i int) *Js According to I return data within the JSON, can be searched step by step

json1 := `{"from":"en","to":"zh","trans_result":[{"src":"today","dst":"\u4eca\u5929"},{"src":"tomorrow","dst":"\u660e\u5929"}]}`c10 := gojson.Json(json1).Getindex(3).Getindex(1).Getindex(1).Get("src").Tostring()fmt.Println(c10) //today

(9) func (j *Js) StringtoArray() []string will {"Result": ["src", "Today", "DST", "\u4eca\u5929″]} data in the JSON of the result corresponding to the data, returned to []string Slice

c11 := gojson.Json(json).Get("result").StringtoArray()fmt.Println(c11) //[src today dst 今天]

func (j *Js) Type()print test, print data type

gojson.Json(json).Get("result").Type()  //[]interface {}
