JSON.RESP

Syntax​

JSON.RESP key [path]

Time complexity: O(N) when path is evaluated to a single value, where N is the size of the value, O(N) when path is evaluated to multiple values, where N is the size of the key

ACL categories: @json

Return the JSON in key in Redis serialization protocol specification form

Examples

Required arguments​

key

is key to parse.

Optional arguments​

path

is JSONPath to specify. Default is root $. This command uses the following mapping from JSON to RESP:

  • JSON null maps to the bulk string reply.
  • JSON false and true values map to the simple string reply.
  • JSON number maps to the integer reply or bulk string reply, depending on type.
  • JSON string maps to the bulk string reply.
  • JSON array is represented as an array reply in which the first element is the simple string reply [, followed by the array's elements.
  • JSON object is represented as an array reply in which the first element is the simple string reply {. Each successive entry represents a key-value pair as a two-entry array reply of the bulk string reply.

For more information about replies, see Redis serialization protocol specification.

Return​
