Multipart/form - HttpClient 4
Hello,
I want to upload a file, or more specific a file and some parameters, in a
multipart/form.
I've not been able to find anything in the API docs or examples that show me
how (for HTTPClient-4).
I've read many places about MultipartRequestEntity - but thats not part of
HTTPCore/Client-4 as far as I can tell.
Is it possible to post multipart data using HTTPClient-4 ?
Thanks in advance!
Magnus

Hi Magnus,
thanks a lot for the feedback. Could you please
open an issue in JIRA and attach the code there?
If you check the "grant license for inclusion
in Apache" box, we can eventually put your code
somewhere into our contrib section.
https://issues.apache.org/jira/browse/HTTPCLIENT
thanks and cheers,
Roland

A very simple wrapper is attached here. This one offcourse requires the
httpclient-3.1.jar in addition to httpclient-4 and httpcore.
There's an issue passing parameters from httpclient-4
HttpMethod.getProperties() (HttpParams from 4) to httpclient-3.1 and
MultipartRequestEntity's constructor which takes HttpMethodParams (from
3.1). I was thinking about doing an iteration of the parameters, but as far
as I could understand HttpMethodParams (from 3.1) is a static configuration,
thus it's alot of typing work and research to map httpclient-4s dynamic
properties to httpclient-3.1 configuration class. Furthermore I didn't find
any way of iterating the the parameters (at a glance). So, I gave that one
up. :)
In conclusion, MultipartRequestEntity is stuck with the default parameters.
http://www.nabble.com/file/p14656312/MultipartEntityWrapper.java
MultipartEntityWrapper.java
It did it's job for me. That was pretty basic stuff, though. :)

Ok, thanks for your advice.
If I make something half-decent - I'll post back here. :)

That is correct. Multipart support is something we didn't port
to the 4.0 API:
http://hc.apache.org/status.html
> Is it possible to post multipart data using HTTPClient-4 ?
Yes, but you'll have to do some coding. There is no
MultipartRequestEntity that you can use out of the box.
One possibility is to re-use the multipart support of HttpClient 3.1:
http://marc.info/?l=httpclient-commons-dev&m=119708907028914&w=2
http://www.nabble.com/multipart-form-data-in-4.0-td14224819.html
If you don't want to depend on HttpClient 3, you can copy the
source and move it into a package of your own application.
hope this helps,
Roland
