<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I noticed that in the nova API we allow to specify body just for the PUT and POST requests [0], for all the other methods, if a body is specified, it gets ignored.<o:p></o:p></p>
<p class="MsoNormal">I had a look at the RFC 7231 [1] and I noticed that just the TRACE must not have a body, for all the other request a body can be passed and managing or ignoring it depends on the semantic of the request.<o:p></o:p></p>
<p class="MsoNormal">For that reason my proposal is to allow at WSGI layer to define a body for all the requests but for the TRACE then it is up to the specific controller to ignore or deal with the body in the request.<o:p></o:p></p>
<p class="MsoNormal">I put a WIP to implement that change [3].<o:p></o:p></p>
<p class="MsoNormal">The rationale behind it is double:<o:p></o:p></p>

</span></span><![endif]>Be more in compliance with the RFC<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-18.0pt;mso-list:l0 level1 lfo2"><![if !supportLists]><span style="mso-list:Ignore">-<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>Having more flexibility in our framework. I have a valid (at least for me) use case here [4]: at the moment a volume detach is implemented using a HTTP DELETE, I’d like to add the option for calling from nova, the cinder –force-delete<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:18.0pt">My idea to implement it is to add a parameter in the body of the DELETE call, but at the moment the only valid option is to create a new API using a POST method.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">What do you think? <o:p></o:p></p>
