Hi, Andreas,
just one feature request: support streaming in WebClient,
i.e. apart from being able to fetch a response content in a single blob,
also provide an API, which would enable WebClient user to read content
step by step,
by using stream protocol, i.e. #next, #next: etc.
I see you having a #streamFrom:to:size:progress:
in WebMessage, but its a little bit too high level (requires an output
stream and includes a progress block)
and its end consumer is a #content message.
It would be nice to have something like:
response := WebClient httpGet: 'http://foo.bar'.
content := response content. "read all at once".
contentStream := response contentStream. "read content using a stream"
[contentStream atEnd] whileFalse: [
c := contentStream next. ....
].
There are some special uses of HTTP protocol which establishing a
permanent socket connection
and then sending a content in a small portions piece by piece over a time.
Obviously, with such kind of connection, if you try to get all content
at once (by using #content) you'll never get it to the end, because
there's always more to read, if you wait long enough.
But if you allow a streaming, then user could read content by portions
and handle portions step by step and don't have to wait till all
content arrives.
