Jsonvalue is a Golang package for JSON parsing. It is used in situations those Go structures cannot achieve, or map[string]interface{}
could not do properly.
Use following statements to import jsonvalue:
import (
jsonvalue "github.com/Andrew-M-C/go.jsonvalue"
)
Sometimes we want to create a complex JSON object like:
{
"someObject": {
"someObject": {
"someObject": {
"message": "Hello, JSON!"
}
}
}
}
With jsonvalue
, It is quite simple to achieve this:
v := jsonvalue.NewObject()
v.Set("Hello, JSON").At("someObject", "someObject", "someObject", "message")
fmt.Println(v.MustMarshalString())
// Output:
// {"someObject":{"someObject":{"someObject":{"message":"Hello, JSON!"}}}
Similarly, it is quite easy to create sub-arrays like:
[
{
"someArray": [
"Hello, JSON!"
]
}
]
v := jsonvalue.NewArray()
v.Set("Hello, JSON").At(0, "someObject", 0)
fmt.Println(v.MustMarshalString())
// Output:
// [{"someObject":["Hello, JSON"]}]
In opposite, to parse and read the first JSON above, you can use jsonvalue like this:
const raw = `{"someObject": {"someObject": {"someObject": {"message": "Hello, JSON!"}}}}`
s := jsonvalue.MustUnmarshalString(s).GetString("someObject", "someObject", "someObject", "message")
fmt.Println(v.MustMarshalString())
// Output:
// Hello, JSON!
However, it is quite complex and annoying in automatically creating array. I strongly suggest using SetArray()
to create the array first, then use Append()
or Insert()
to set array elements. Please refer go godoc.
