#18523 closed New feature (fixed)

Add getvalue to HttpResponse

The HttpResponse object can almost be used as another stream object. Unfortunately, it doesn't offer the getvalue() method to be able to read its content, hence requiring conditional code in some circonstances (see #15197). What about adding it (HttpResponse.getvalue() === HttpResponse.content)?

Good idea.

Do Python's docs provide a list of the methods that a "stream object" must support? While we're there, we should also check that HttpRequest objects support all the methods that make sense.

I think lists basic API for streams.

I would add the following attributes and methods:

  • HttpResponseBase.closed: set to False in __init__, set to True in close()
  • HttpResponseBase.writable(): returns False because write(content) raises an exception (should be changed to IOError BTW)
  • HttpResponseBase.writelines(lines): raises IOError
  • HttpResponseBase.tell(): change it to raise IOError
  • HttpResponse.getvalue(): returns self.content
  • HttpResponse.writelines(lines): writes each line with self.write(line)

  • Has patch set
  • Owner changed from nobody to Osmose
  • Status changed from new to assigned

I submitted a PR with the changes mentioned in comment:3 here: . If we think that all of the stuff from io.IOBase should be included, I can update my PR with the rest.

In ebc8e79cf3bdd42a99e91d6e679248d07097d3db:

Fixed #18523 -- Added stream-like API to HttpResponse.

Added getvalue() to HttpResponse to return the content of the response,
along with a few other methods to partially match io.IOBase.

Thanks Claude Paroz for the suggestion and Nick Sanford for review.
