Pass parameters to Airflow Experimental REST api when creating dag run

问题

Looks like Airflow has an experimental REST api that allow users to create dag runs with https POST request. This is awesome.

Is there a way to pass parameters via HTTP to the create dag run? Judging from the official docs, found here, it would seem the answer is "no" but I'm hoping I'm wrong.

回答1:

I had the same issue. "conf" value must be in string

curl -X POST \
    http://localhost:8080/api/experimental/dags/<DAG_ID>/dag_runs \
    -H 'Cache-Control: no-cache' \
    -H 'Content-Type: application/json' \
    -d '{"conf":"{\"key\":\"value\"}"}'

回答2:

Judging from the source code, it would appear as though parameters can be passed into the dag run.

If the body of the http request contains json, and that json contains a top level key conf the value of the conf key will be passed to as configuration trigger_dag. More on how this works can be found here.
