Use Gojson in the GO program to parse JSON format files _golang

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

 Go to Github.com/widuu/gojson

Use introduction

Structure

Copy Code code as follows:

Type Js struct {
Data interface{}
}

(1) Func JSON (data) *js data is a string type, initializes the Js structure, parses Json, and return Js.data

Copy Code code as follows:

JSON: = ' {' from ': ' en ', ' to ': ' En '} '
C1: = Gojson. JSON (JSON)//&{map[from:en To:zh]}

(2) func (*JS) get () *js gets a value in a simple JSON, recursive lookup, return js.data

Copy Code code as follows:

JSON: = ' {' from ': "en", "to": "en", "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)//&{today}

C2: = Gojson. JSON (JSON). Get (' from ')
Fmt. Println (C2)//&{en}

(3) func (*JS) Tostring () string converts a single data to a string type because the string type is better than the other types. Let the data return string

Copy Code code as follows:

C2: = Gojson. JSON (JSON). Get (' from '). Tostring ()
Fmt. Println (C2)//en

(4) Func (J *js) GetPath (args ... string) *js get a value by entering multiple arguments of string, the JSON data must be recursive

Copy Code code as follows:

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 based on the input num, and is limited to handling {"result": [SRC], "Today", "DST", "\u4eca value in [] in \u5929″]}

Copy Code code as follows:

JSON: = ' {' from ': "en", "to": "en", "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 to have duplicate data in the data, take value, use js.data must be []interface{} type, this is the Baidu translation when the return of Js may use

Copy Code code as follows:

Json1: = ' {' from ': "en", "to": "en", "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)/Then returns SRC in the first group of Trans_result today

(7) Func (J *js) ToArray () (k, d []string) converts the JSON data into the corresponding array of key []string{} value []string{} One by one, only to two levels and not to the multilevel

Copy Code code as follows:

c9k, c9v: = Gojson. Json (Json1). Get ("Trans_result"). ToArray ()
Fmt. Println (c9k, c9v)//[src DST SRC DST] [today tomorrow tomorrow]

C3K, c3v: = Gojson. JSON (JSON). GetIndex (1). ToArray ()
Fmt. Println (c3k, C3V)//[from] [en]

(8) Func (J *js) GetIndex (i int) *JS returns the data within JSON according to i, can be searched step by step

Copy Code code as follows:

Json1: = ' {' from ': "en", "to": "en", "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 data JSON, return to [] Slice of string

Copy Code code as follows:

C11: = Gojson. JSON (JSON). Get (' result '). StringToArray ()
Fmt. Println (C11)//[src today DST]

(a) Func (J *js) type () print test, print data type

Copy Code code as follows:

Gojson. JSON (JSON). Get (' result '). Type ()//[]interface {}
