HttpURLConnection DELETE with url params
Thank you @dnault. Updating to Java 1.8 and sending initiator_id as form parameter fixed the issue.
How to send Entity in API DELETE with HTTP-CLIENT
As told in the coments by Ewramner and VoiceOfUnreason and in the edits:
1: The answer about how to make this was found in an older post of StackOverflow: setEntity in HttpDelete
2: The answer about "Should I just talk with the people who made the API and ask them to change their configuration to allow us to send the info by params?" was answered by both of them. While it´s not forbidden, it´s something thats not recommended.
My course of action will be:
1: Talk with the people responsible for the API to give them info about this situation.
2: Ask our Architecture team to create a new method that will allow us to do HttpDelete calls with an entity body, just in case that we have to make more API calls like this one.
With this i think all my answers are solved.
Again, Thank you.
Sending HTTP DELETE request in Android
The problematic line is con.setDoOutput(true);
. Removing that will fix the error.
You can add request headers to a DELETE, using addRequestProperty
or setRequestProperty
, but you cannot add a request body.
