Introduction
This example shows how to use the builtin json module to parse and serialize JSON Objects and Arrays.
If you have any questions please contact us at support@interfaceware.com.
Using the Code [top]
- Import the Parse and serialize JSON channel from the Builtin: Iguana Protocols repository
- Experiment with the code to find out how it works
- Then add the module(s) to your Translator project
- Adapt the code to your own requirements
- Use
json.parse{}to parse JSON Objects or Arrays - Use
json.serialize{}to serialize a table into a JSON Object or Array - Interactive scripting help is included for this module
This is the github code for the main module:
The example1.lua code uses simple XML to demonstrate parsing and serialization:
The other two local files use a more realistic demographic example, example2.lua uses a JSON object and example3.lua uses a JSON table.
How it works [top]
The code uses json.parse{} to parse both a JSON Object and a JSON Array into two tables. It then uses json.serialize{} to serialize the tables into a JSON Object and Array. You can inspect the annotations to see how this works.
The code is broken into three local files: The first example (example1.lua) uses a very simple XML example, the second and third examples (example2.lua and example3.lua) use a more realistic demographic example.
