Suddenly found a very useful Golang JSON library

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

Json

I don't want to explain what JSON is.

Library nameGJSON

Point here to star thank you little brother

Download

$ go get -u github.com/tidwall/gjson

What's the difference from the official JSON parsing package?

The official package is a whole piece of data packaged/parsed together.
Have the following data

struct {  str1  str2}json :{str1:"xx",str2:"xx"}

If you want to get str1 alone, it's troublesome.

The official Demo

package mainimport "github.com/tidwall/gjson"const json = `{"name":{"first":"Janet","last":"Prichard"},"age":47}`func main() {    value := gjson.Get(json, "name.last")    println(value.String())}

Output:Prichard

I wrote the super detailed example!

To show you the JSON I want to parse, I ask you to be afraid:

Golang code (these four strings of JSON can be solved together, so a piece of code can be done)
