# gojsonpointer
|

|
|
An implementation of JSON Pointer - Go language
|
||
|
|
|

## Usage
|
||
|
|
jsonText := `{
|
||
|
|
"name": "Bobby B",
|
||
|
|
"occupation": {
|
||
|
|
"title" : "King",
|
||
|
|
"years" : 15,
|
||

|
||
|
|
}
|
||
|
|
}`
|
||
|
|
|
||
|
|
var jsonDocument map[string]interface{}
|
||
|
|
json.Unmarshal([]byte(jsonText), &jsonDocument)
|
||
|
|
|
||
|
|
//create a JSON pointer
|
||
|
|
pointerString := "/occupation/title"
|
||
|
|
pointer, _ := NewJsonPointer(pointerString)
|
||
|
|
|
||
|
|
//SET a new value for the "title" in the document
|
||
|
|
pointer.Set(jsonDocument, "Supreme Leader of Westeros")
|
||
|
|
|
||
|
|
//GET the new "title" from the document
|
||
|
|
title, _, _ := pointer.Get(jsonDocument)
|
||
|
|
fmt.Println(title) //outputs "Supreme Leader of Westeros"
|
||
|
|
|
||
|
|
//DELETE the "heir" from the document
|
||
|
|
deletePointer := NewJsonPointer("/occupation/heir")
|
||
|
|
deletePointer.Delete(jsonDocument)
|
||
|
|
|
||
|
|
b, _ := json.Marshal(jsonDocument)
|
||
|
|
fmt.Println(string(b))
|
||
|
|
//outputs `{"name":"Bobby B","occupation":{"title":"Supreme Leader of Westeros","years":15}}`
