32164	Broken content_length header in AsyncTestClient when doing post requests with json data	patrick	nobody	"Hello there, this is my first formal bug report, so I hope I'm doing this correctly. Anyway I was working on a async view and adding a test for it but I got this error:


{{{

after digging a bit it looks like we set the content_length to `bytes(len(data))`, which seems to be wrong, since it produces this string:

{{{
'\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00'
}}}

Code is here: https://github.com/django/django/blob/d1791539a7d86739cd44c909fa8239cae7f85874/django/test/client.py#L543

Also I did a patch for this which seems to work: https://github.com/django/django/pull/13632
