z3c.json 0.5.1

Zope3 JSON base libraries

This package provides basic JSON components like JSON reader and writer utilities and a JSON-RPC client proxy including the transport implementation for Zope3.

Detailed Documentation

README

We can use the JSONReader and JSONWriter if we need to convert a data structure to or from JSON syntax – in other words a EcmaScript mapping object. Let’s check the utilities:

>>> import zope.component
>>> from z3c.json import interfaces
>>> from z3c.json import testing
>>> testing.setUpJSONConverter()

JSONWriter Utility

>>> jsonWriter = zope.component.getUtility(interfaces.IJSONWriter)
>>> jsonWriter
<z3c.json.converter.JSONWriter object at ...>

Read some data:

>>> input = {u'a': ['fred', 7],
...          u'b':['mary', 1.234]}
>>> jsonStr = jsonWriter.write(input)
>>> jsonStr
u'{"a":["fred",7],"b":["mary",1.234]}'

JSONReader Utility

>>> jsonReader = zope.component.getUtility(interfaces.IJSONReader)
>>> jsonReader
<z3c.json.converter.JSONReader object at ...>

Conver the data back to python:

>>> output = jsonReader.read(jsonStr)
>>> output
{u'a': [u'fred', 7], u'b': [u'mary', 1.234]}

>>> input == output
True
