Return the serialized JSON at one or multiple paths.
Syntax
JSON.GET <key> [INDENT indentation-string] [NEWLINE newline-string] [SPACE space-string] [NOESCAPE] [path ...]
key (required) – key of JSON document type
INDENT/NEWLINE/SPACE (optional) – controls the format of the returned JSON string, i.e., "pretty print". The default value of each one is empty string. They can be overidden in any combination. They can be specified in any order.
NOESCAPE - optional, allowed to be present for legacy compatibility and has no other effect.
path (optional) – zero or more JSON paths, defaults to the root if none is given. The path arguments must be placed at the end.
Return
Enhanced path syntax:
If one path is given:
Return serialized string of an array of values.
-
If no value is selected, the command returns an empty array.
If multiple paths are given:
Return a stringified JSON object, in which each path is a key.
-
If there are mixed enhanced and restricted path syntax, the result conforms to the enhanced syntax.
If a path does not exist, its corresponding value is an empty array.
Examples
Enhanced path syntax:

OK

Restricted path syntax:
