In the previous step, you logged a static message that said
"This is a test". A more realistic use case is logging the value of a
message flow variable in an
API proxy flow.
In this step, you'll log your client IP address, which is a property of the client
flow variable.
To log your client IP address with your extension:
In the API proxy editor, select the Develop tab.
Click your extension logging policy and change the value of message:
FROM:
"message": "This is a test"
TO:
"message": "Client IP: {client.ip}"
Save the proxy.
Select the Trace tab.
Click Start Trace Session, and click Send.
Open the GCP console and go to Logging.
Select the following:
Global
example-log
Last Hour
You should see a log entry with your client IP address.
