JSON Patch, as described here and as specified in RFC 6902 from the IETF, is a format for describing changes to JSON documents using operations like add, remove, replace, copy, move and test. The experimental JSON Patch assertion can apply JSON Patch operations to JSON documents in policy on the Layer7 API Gateway. Some users may find this easier and faster than using the Javascript assertion to do the same.
For example, this JSON Patch:
[
{
"op": "remove",
"path": "/bad"
},
{
"op": "replace",
"path": "/baz",
"value": "boo"
},
{
"op": "add",
"path": "/hello",
"value": [
"world",
"system",
"galaxy",
"universe"
]
},
{
"op": "add",
"path": "/car",
"value": {
"make": "Honda",
"model": "Civic"
}
}
]
Applied to this JSON message:
{
"baz": "qux",
"foo": "bar",
"bad": "stuff"
}
Would return this result:
{
"foo": "bar",
"baz": "boo",
"hello": [
"world",
"system",
"galaxy",
"universe"
],
"car": {
"make": "Honda",
"model": "Civic"
}
}
When configuring the assertion in policy as so:
