Subject [jira] [Resolved] (HTTPCLIENT-1548) Duplicated rewquest headers with MultipartEntityBuilder and file PUT
Date Fri, 22 Aug 2014 06:43:11 GMT

     [ https://issues.apache.org/jira/browse/HTTPCLIENT-1548?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Oleg Kalnichevski resolved HTTPCLIENT-1548.

    Resolution: Invalid

You are mis-using MultipartEntityBuilder by manually overriding the standard content type,
hence extra headers in the content body on the server side. The server side handler assumes
the content to be of type {{application/x-shockwave-flash}} instead of {{multipart/form-data}}.

putRequest.setHeader(HttpHeaders.CONTENT_TYPE, this.getMimeForExtension(extension));

> Problem arises when wanting to upload files via put to AWS S3 servers (not tested with
other servers as it is a problem on the client side). The creation usage of MultipartEntityBuilder
creates duplicated request headers which the remote server interprets as part of the file
corrupting them. The file has header test on the beginning and end as it is interpreted as
file content.
