Here's the relevant section of RFC 7230:
The presence of a message body in a request is signaled by a
Content-Length or Transfer-Encoding header field. Request message
framing is independent of method semantics, even if the method does
not define any use for a message body.
So I think tiny_http is right to ignore message bodies if neither Content-Length nor Transfer-Encoding is provided.
Right now there are two ways to provide a message body in ureq: .send_string()
and .send()
. If you want to send arbitrary binary content (i.e. not UTF-8), you need to use .send()
. The user of ureq
can currently choose between Content-Length (if they know the size of the data they'll send) or Transfer-Encoding (if they don't). It would be great to add some support to make it easier to do the right thing, but keep in mind making .send()
always set Transfer-Encoding would effectively force chunked encoding for anyone who wants to send message bodies containing arbitrary bytes.
That would probably be okay, since the HTTP spec makes it mandatory to support chunked encoding:
A recipient MUST be able to parse the chunked transfer coding
(Section 4.1) because it plays a crucial role in framing messages
when the payload body size is not known in advance.
But that's definitely worth documenting. And if it turns out in the future that this causes compatibility problems, ureq could add a send_bytes(bytes: Vec<u8>)
for arbitrary bytes of known size.

Oops, I see that there already is a .send_bytes()
! I was going off the documentation https://docs.rs/ureq/1.1.2/ureq/index.html#plain-requests. I've added that to my documentation PR #73, along with some notes on the current implementation of chunked encoding for .send()
.
Based on that updated understanding, I agree it makes sense to set Transfer-Encoding: chunked for the user when .send()
is called. I also think it would be nice to error out if both Transfer-Encoding and Content-Length are set.

You're right! It could be good to set this header if we haven't set a content-length already. At this point it would be a (subtle) breaking change, so not entirely how to handle it.
Maybe submit a PR and we do it when we bump to 0.13.0?
I'm not rewriting ureq
, it will stay the same (sync forever), and I will keep maintaining it until there's 0 interest in it. My rewrite efforts are in hreq
.

Alright, thank you for your answer! I'll submit a PR when I have some time: I have a pretty good idea where to do the edit.

I believe this is working now.
