Getting started
An example request file would look something like:
args: - id: 1 # specify 1 as defaultmethod: GETendpoint: http://jsonplaceholder.typicode.com/todos/{id} # we can use 'id' hereheaders: - Content-Type: application/json - Accept: application/jsonallow-headers: # only show these headers in the output - Content-TypeThis request can be called with:
> sendex run get-todo.yml id=5200 OKContent-Type: application/json; charset=utf-8{ "userId": 1, "id": 5, "title": "laboriosam mollitia et enim quasi adipisci quia provident illum", "completed": false}Which will then make a request to the URL http://jsonplaceholder.typicode.com/todos/5, and the response will be displayed in the terminal, only showing the Content-Type headers.
