ByteArrayBody as an alternative to InputStreamBody
--------------------------------------------------
Key: HTTPCLIENT-1014
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1014
Project: HttpComponents HttpClient
Issue Type: New Feature
Components: HttpClient
Affects Versions: 4.1 Alpha2
Reporter: Axel Fontaine
InputStreamBody can not determine the content length, which in turn causes
requests to be sent with a content length of 0, even though the content is
there. .NET Servers have trouble dealing with this.
ByteArrayBody provides an alternative that alliviates this limitation.

import java.io.IOException;
import java.io.OutputStream;
import org.apache.http.entity.mime.MIME;
import org.apache.http.entity.mime.content.AbstractContentBody;
/**
* Body part that is built using a byte array containing a file.

public class ByteArrayBody extends AbstractContentBody {
/**
* The contents of the file contained in this part.

private byte[] data;
/**
* The name of the file contained in this part.

/**

public ByteArrayBody(final byte[] data, final String mimeType, final String
filename) {
super(mimeType);
if (data == null) {
throw new IllegalArgumentException("byte[] may not be null");
}
this.data = data;
this.filename = filename;
}
/**

public ByteArrayBody(final byte[] data, final String filename) {
this(data, "application/octet-stream", filename);
}
@Override

return filename;
