How to complete the challenge POST /todos XML to JSON
When an API supports multiple formats in request and response we might be able to mix and match. In this challenge we send a POST request to create a todo item using XML but receive JSON response.
POST /todos XML to JSON
Issue a POST request on the
/todos
end point to create a todo using Content-Typeapplication/xml
but Acceptapplication/json
POST
request means we will send information in the body of the message- e.g.
POST /todos
sends to the todos endpoint
- e.g.
create a todo
means that the payload will be valid data to create a todo itemusing Content-Type
application/xml
means that we will setcontent-type
header toapplication/xml
and the payload will be in XML formatAccept
application/json
means add anaccept
header ofapplication/json
to receive the response in JSON format- add the
X-CHALLENGER
header to track progress
Basic Instructions
We can mix different accept and content-types so we can send payloads in one format, and receive responses in another format. This challenge is about sending payload in XML but having the response in JSON.
- Issue a
POST
request to end point "/todos"- if running locally that endpoint would be
http://apichallenges.eviltester.com/todos
- if running locally that endpoint would be
- The request should have an
Content-Type
header ofapplication/xml
- add a valid payload in XML format to create a todo item e.g.
<todo>
<doneStatus>true</doneStatus>
<title>file paperwork today</title>
</todo>
- add an
accept
header ofapplication/json
to receive the response in JSON format - The request should have an
X-CHALLENGER
header to track challenge completion - The response status code should be
201
when all the details are valid. - Check the body of the response has JSON formatted todo item with full details of the created item
- Check the location header for the REST API call to retrieve details of the created item
Extras:
- try GET the location header URL to return the created todo item
