Reporter: Dominik Dorn
Priority: Critical
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.
