JavaScript Object Notation

JSON (JavaScript Object Notation) is a human-readable format for storing and transmitting data objects. Many web services use JSON for making and receiving requests. In MaSH we can use JSON to store, send, read and retrieve variables and objects. You can read more about JSON here here.

Encoding JSON

encode

mash.json.encode(mixed: data) -> String

Encodes data and returns a string.

Parameters

data

A variable or object to be encoded.

Natural

set dictionary to { name: "Grace Hopper", occupation: "Computer Scientist" }

set json to mash.json.encode(dictionary)

printline json

Standard

dictionary = { name: "Grace Hopper", occupation: "Computer Scientist" }

json = mash.json.encode(dictionary)

printline(json)

Output

{"name":"Grace Hopper","occupation":"Computer Scientist"}

Decoding JSON

decode

mash.json.decode(string: json) -> Object

Decodes a JSON string and returns an object.

Parameters

json

A JSON-encoded string.

Natural

set json to '{"name":"Grace Hopper","occupation":"Computer Scientist"}'

set object to mash.json.decode(json)

printline object

Standard

json = '{"name":"Grace Hopper","occupation":"Computer Scientist"}'

object = mash.json.decode(json)

printline(object)

Output

Object {
    "name": "Grace Hopper",
    "occupation": "Computer Scientist"
}

Notes

If you’re using the mash.http library you can take advantage of the json property on a Response object to automatically decode JSON data.
