Make a note of the API endpoint that is logged to the console during deployment.
endpoints:
GET https://xxx.api-gw.mybluemix.net/python-service/ping --> python-service-dev-currentTime
serverless invoke --function currentTime
or serverless invoke -f currentTime
-f
is shorthand for --function
In your terminal window you should see the response from Apache OpenWhisk
{
"message": "Hello stranger, the current time is 15:59:30.983379"
}
Use a HTTP client to access the endpoint for your function. The endpoint will be the API gateway root path, logged during deployment, and your configured function path.
$ http get https://xxx.api-gw.mybluemix.net/python-service/ping
HTTP/1.1 200 OK
...
{
"message": "Hello stranger, the current time is 16:00:11.837331"
}
$ http get https://xxx.api-gw.mybluemix.net/python-service/ping?name=James
HTTP/1.1 200 OK
...
{
"message": "Hello James, the current time is 16:00:15.749699"
}
