Calling Google Cloud function with arguments - function

Question

I have a function which fetch sql file from Cloud storage. This function accept project_id,bucket_id & sql_file
from google.cloud import storage
def read_sql(request):
request_json = request.get_json(silent=True)
project_id=request_json['project_id']
bucket_id=request_json['bucket_id']
sql_file=request_json['sql_file']
gcs_client = storage.Client(project_id)
bucket = gcs_client.get_bucket(bucket_id)
blob = bucket.get_blob(sql_file)
contents = blob.download_as_string()
return contents.decode('utf-8')
It works fine when I test it with these parameters
{"project_id":"my_project","bucket_id":"my_bucket","sql_file":"daily_load.sql"}
I am trying to call this function in Google WorkFlow but don't know how to setup arguments in call http.get
main:
params: []
steps:
- init:
assign:
- project: ${sys.get_env("GOOGLE_CLOUD_PROJECT_ID")}
- location: "us-central1"
- name: "workflow_test_return_sql1"
- service_account: "sa#appspot.gserviceaccount.com" # Use App Engine default SA.
- get_function:
call: googleapis.cloudfunctions.v1.projects.locations.functions.get
args:
name: ${"projects/" + project + "/locations/" + location + "/functions/" + name}
result: function
- grant_permission_to_all:
call: googleapis.cloudfunctions.v1.projects.locations.functions.setIamPolicy
args:
resource: ${"projects/" + project + "/locations/" + location + "/functions/" + name}
body:
policy:
bindings:
- members: ["allUsers"]
role: "roles/cloudfunctions.invoker"
- call_function:
call: http.get
args:
url: ${function.httpsTrigger.url}
result: resp
Code written in Workflow is yaml
Any idea how to build function call URL with arguments ?
I have tried below two approached but they didn't work
- call_function:
call: http.post
args:
url: ${function.httpsTrigger.url}
body:
input: {"project_id":"my_project","bucket_id":"my_bucket","sql_file":"daily_load.sql"}
result: resp
and
- call_function:
call: http.get
args:
url: ${function.httpsTrigger.url}?project_id=my_project?bucket_id=my_bucket?sql_file=daily_load.sql

Answer 1

You are close!! Try that
- call_function:
call: http.get
args:
url: ${function.httpsTrigger.url + "?project_id=" + my_project + "&bucket_id=" + my_bucket + "&sql_file=" + daily_load.sql}
EDIT 1
Here the post option with JSON body (note that YAML and JSON are similar. here how to write your JSON with yaml)
- call_function:
call: http.post
args:
url: ${function.httpsTrigger.url}
body:
project_id: "my_project"
bucket_id: "my_bucket"
sql_file: "daily_load.sql"
result: resp
