JSON
JSON (JavaScript Object Notation) is a way of expressing information.[1] JSON is usually easy to understand. It can express information like XML.[2] It is based on JavaScript's notation for object literals.[3] However, JSON is stricter.[3]
JSON and XML are both often used in AJAX.[4] Even though JSON is named after JavaScript, it can be used in other programming languages, such as Python (PHP, etc.)[5]
Example
This is an example of JSON: <syntaxhighlight lang="javascript"> {
"firstName": "John",
"lastName" : "Smith",
"age" : 25,
"address" :
{
"streetAddress": "21 2nd Street",
"city" : "New York",
"state" : "NY",
"postalCode" : "10021"
},
"phoneNumber":
[
{
"type" : "",
"number": "212 555-1234"
},
{
"type" : "fax",
"number": "646 555-4567"
}
]
}
</syntaxhighlight>
JSON Encoding and Decoding in Python
Encoding: <syntaxhighlight lang="python"> import json
sampleDict = {
"firstName": "John", "lastName" : "Smith"
}
sampleJson = json.dumps(sampleDict, indent=4) </syntaxhighlight>
Decoding: <syntaxhighlight lang="python"> import json
- A JSON string or can be a JSON response
sampleJson = """{ "firstName": "John", "lastName" : "Smith"}"""
sampleDict = json.loads(sampleJson) print(sampleDict['firstName']) print(sampleDict['lastName']) </syntaxhighlight>
