Sending mixed type multipart

[vegetable]

Hello there,

I'm trying to use the client to make a REST request as multipart/form-data.

I manage to include files and text content with their mimetypes, but:

• I don't receive file names, nor sizes (file name is set as part name)
• I receive type form-data and I think, as its a file, i should receive file type in Content-Disposition
• I don't receive the mimetype of the files

Thanks for the good job and keep improving :)

Are you using Multipart Body or String Body?

[vegetable]

I add parts using buttons (file for files and string for json).

Let the client guess mimetype from file, and set it to application/json for json text param

This is the request that is generated by RESTClient (captured by TCPMon):

POST / HTTP/1.1
Content-Length: 424
Content-Type: multipart/form-data; boundary=mF1uMK_2yoTUqlDfHF9Uy_aHUZkAE40xGSIUNCYs
Host: 127.0.0.1:10102
Connection: Keep-Alive
User-Agent: Apache-HttpClient/4.3.1 (java 1.5)

--mF1uMK_2yoTUqlDfHF9Uy_aHUZkAE40xGSIUNCYs
Content-Disposition: form-data; name="hello.txt"
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: binary

Hello World!


--mF1uMK_2yoTUqlDfHF9Uy_aHUZkAE40xGSIUNCYs
Content-Disposition: form-data; name="str-name"
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

String content part
--mF1uMK_2yoTUqlDfHF9Uy_aHUZkAE40xGSIUNCYs--

You asked three questions:

1. I don't receive file names, nor sizes (file name is set as part name)

I see:

Content-Length: 424

being set for the request. Do you need Content-Length for each part?

I believe that you want filename attribute in addition to name attribute for the Content-Disposition header as detailed in this SO question. Let me see the possibility of including this.

2. I receive type form-data and I think, as its a file, i should receive file type in Content-Disposition

I see Content-Disposition being received as:

Content-Disposition: form-data; name="hello.txt"
Content-Disposition: form-data; name="str-name"

I would like to know what you are expecting instead of form-data?

3. I don't receive the mimetype of the files

I do see mime type being set in Content-Type header for each part.

Thanks for the quick response! First to say that I'm not a specialist in this stuff, so I may be wrong.

1. That's it, i want to send several files included in a named part ("files" for example)

So i name that part as "files" and add the file. Now filename is lost as name refers to part name instead of filename. Content-Disposition should be:
Content-Disposition: file; name="files"; filename="hello.txt"

as in:
http://www.w3.org/TR/html401/interact/forms.html#h-17.13.4.2
bottom example

So as you say, including filename should mend this.

2. I spect output similar to the one in the previous link. In the examples, if only one file is sent, it sets form-data, but if several are added, they get group together with type file. Don't if only using form-data would cause any problem.

3. I do not receive it in my server, maybe a coding problem. Please try with a jpg file or similar as I think text/plain utf8 is default.

Thanks again :D

The example quoted by you:

Content-Type: multipart/form-data; boundary=AaB03x

--AaB03x
Content-Disposition: form-data; name="submit-name"

Larry
--AaB03x
Content-Disposition: form-data; name="files"
Content-Type: multipart/mixed; boundary=BbC04y

--BbC04y
Content-Disposition: file; filename="file1.txt"
Content-Type: text/plain

... contents of file1.txt ...
--BbC04y
Content-Disposition: file; filename="file2.gif"
Content-Type: image/gif
Content-Transfer-Encoding: binary

...contents of file2.gif...
--BbC04y--
--AaB03x--

I fixed the filename attribute--now filename is added to file parts.

Not sure if grouping of multiple files under one name is possible. Will explore it later.

Think this dialog needs to accept another parameter Name.

[vegetable]

in fact it should be added as the name of the uploaded file

name parameter should be the same as with string parameters
