JSON Parser sample configuration

In this example, the attribute connector is configured to parse the contents of the XACML attribute pip.payload, which originated from the HTTP Attribute Connector. The parsing uses the parameterized JSONPath expression $.authorizations[?(@.id=='##1##')].status to extract values.**

The parameter ##1## within the expression is populated by the value of the XACML attribute pip.username.

**Finally, the extracted values are provided to the connector host in the XACML attribute pip.status.

In this configuration, when the connector is queried for the attribute pip.status with the following values:

• pip.payload as { "authorizations": [ { "id": "a123", "status": "ok"} ] }
• pip.username as a123

it will return ok.
