interpolateServiceData
Description copied from interface:CredHubInterpolationOperations
Search the provided data structure of bound service credentials, looking for references to CredHub credentials. Any CredHub credentials found in the data structure will be replaced by the credential value stored in CredHub. Example: A JSON data structure parsed from a VCAP_SERVICES environment variable might look like this if the service broker that provided the binding is integrated with CredHub:{ "service-offering": [{ "credentials": { "credhub-ref": "((/c/service-broker/service-offering/1111-2222-3333-4444/credentials))" } "label": "service-offering", "name": "service-instance", "plan": "standard", "tags": [" "cloud-service" ] }] }
{ "service-offering": [{ "credentials": { "url": "https://servicehost.example.com/", "username": "someuser", "password": "secret" } "label": "service-offering", "name": "service-instance", "plan": "standard", "tags": [" "cloud-service" ] }] }
