Oleg Kalnichevski commented on HTTPCLIENT-971:
----------------------------------------------
> <code>
> Content-Type: multipart/form-data; boundary=AaB03x
>
> --AaB03x
> </code>
> which is exactly what is missing in the current behavior and what I'm asking
> for.
Which is exactly what is ambiguous in the spec as it is not clear whether the
Content-Type is meant to be a part of the message head or a message body.
> This is also the only thing that differs between a fileupload in firefox and
> httpcomponents-client.
Feel free to post a wire dump to demonstrate that.
> If you're not going to fix it, please tell me how to do it myself (at least a
> hint).
You will have to adjust HttpMultipart#doWriteTo() private method

> When doing a multipart post, with a code like this:
> <code>
> HttpPost post = new HttpPost("http://"; + host + ":" + port + uploadUrl +
> token.getProgressToken());
> HttpContext context = new BasicHttpContext();
> CookieStore store = cred.getCookieStore();
> context.setAttribute(ClientContext.COOKIE_STORE, store);
> MultipartEntity entity = new MultipartEntity();
> HttpResponse response;
> try{
> entity.addPart("document[pdf_file]", new FileBody(file));
> entity.addPart("authenticity_token", new
> StringBody(token.getAuthenticityToken(), Charset.forName("UTF-8")));
> entity.addPart("document[progress_token]", new
> StringBody(token.getProgressToken(), Charset.forName("UTF-8")));
> post.setEntity(entity);
> HttpClient client = new DefaultHttpClient();
> response = client.execute(post, context);
> </code>
> The required initializing Header
> <code>
> Content-Type: multipart/form-data;
> boundary=---------------------------15590059519136285452113363602
> Content-Length: 38377
> -----------------------------15590059519136285452113363602
> Content-Disposition: form-data; name="authenticity_token"
> VkJ/mnCDmImYfEVT0zNFBvyyhihKSaUX5j7Vm7d0WUQ=
> </code>
> is missing.
> Instead it directly starts with
> <code>
> --gDRYDFqyzjuUrRL5No6B5wHN6BT5Ts2
> Content-Disposition: form-data; name="authenticity_token"
> Content-Type: text/plain; charset=UTF-8
> Content-Transfer-Encoding: 8bit
> rvMzKRruVZaKX7JV+4Zpg7LWdxEuhq2hSgtaCIcSzCg=
> </code>
> The target server ( a rails one ) seems not to be able to understand this
> multipart upload.
> I think the correct place to fix is
> org.apache.http.entity.mime.MultipartEntity but I'm not sure where and how to
> do it.
> Please help.
