json

Contains constants and functions for handling JSON data. Substation relies on https://github.com/tidwall/gjson for reading JSON and https://github.com/tidwall/sjson for writing JSON; all features related to reading and writing from those projects are supported, refer to their documentation for further detail.

Variables

var Types = map[gjson.Type]string{
	0: "Null",
	1: "Boolean",
	2: "Number",
	3: "String",
	4: "Boolean",
	5: "JSON",
}

Types maps gjson.Type to strings.

Functions

func DeepEquals

func DeepEquals(s1, s2 []byte) (bool, error)

DeepEquals performs a deep equals comparison between two byte arrays.

func Delete

func Delete(json []byte, key string) (tmp []byte, err error)

Delete wraps sjson.DeleteBytes.

func Set

func Set(json []byte, key string, value interface{}) (tmp []byte, err error)

Set inserts values into JSON and operates under these conditions (in order):

- If the value is valid JSON (bytes, string, or Result), then it is inserted using SetRaw to properly insert it as nested JSON; this avoids encoding that would otherwise create invalid JSON (e.g. `{\"foo\":\"bar\"}`)

- If the value is bytes, then it is converted to a base64 encoded string (this is the behavior of the standard library's encoding/json package)

- If the value is Result, then it is converted to the underlying GJSON Value

- All other values are inserted as interfaces and are converted by SJSON to the proper format

func SetRaw

func SetRaw(json []byte, key string, value interface{}) (tmp []byte, err error)

SetRaw wraps sjson.SetRawBytes and conditionally converts values to properly insert them as nested JSON.

func Valid

func Valid(data interface{}) bool

Valid conditionally checks if bytes, strings, or Results are valid JSON objects.

Types

type Result

type Result = gjson.Result

Result wraps gjson.Result.

func Get

func Get(json []byte, key string) Result

Get wraps gjson.GetBytes.
