将Content-ID添加到多部分实体

鉴于我们已提出多部分请求 . 我们现在需要提供内容ID . 下面是我们尝试用来创建multipart请求的代码：

MultipartEntity mpEntity = new MultipartEntity();
StringBody body;
try
{
    body = new StringBody( xml, "application/xml", Charset.forName( "UTF-8" ) );
    byte[] data = getBytesFromFile( image );
    ByteArrayBody bab = new ByteArrayBody( data, "image/jpeg", "test_image_cid" );
    mpEntity.addPart( "body", body );
    mpEntity.addPart( "test_image_cid", bab );

} catch ( UnsupportedEncodingException e )
{
    e.printStackTrace();
}

HttpPost request = new HttpPost("http://10.1.1.1");
request.addHeader( "Authorization", authorization_header_values );
request.addHeader( "Content-Type", "Multipart/Related" );
request.setEntity( mpEntity );
return request;

这就是我们要求的Web服务所要求的：

<?xml version="1.0" encoding="utf-8"?> <request method="receipt.create"> 
   <receipt>
       <expense_id>1</expense_id>  <!-- id of expense -->
       <image>cid:xxxxxxxxxxxxx</image> <!-- content-id used on the related binary content -->
   </receipt>
</request>

这是我们从服务器返回进行调试的内容：

POST / HTTP / 1.1授权：OAuth realm =“”，oauth_version =“1.0”，oauth_consumer_key =“key”，oauth_token =“token”，oauth_timestamp =“1358197676614”，oauth_nonce =“1111111”，oauth_signature_method =“PLAINTEXT”，oauth_signature =“signature”内容类型：Multipart / Related User-Agent：agent Content-Length：2336363 Host：10.1.1.1 Connection：Keep-Alive

--HPeiFlrswQmM8Mi1uoWpzJRfrnp3AMtZjpCdt Content-Disposition：form-data; name =“body”Content-Type：application / xml; charset = UTF-8 Content-Transfer-Encoding：8bit

<?xml version='1.0' encoding='UTF-8' ?>
    <request method="receipt.create">
        <receipt>
            <expense_id>979</expense_id>
            <image>cid:test_image_cid</image>
        </receipt>
    </request>

--HPeiFlrswQmM8Mi1uoWpzJRfrnp3AMtZjpCdt Content-Disposition：form-data; NAME = “test_image_cid”; filename =“test_image_cid”Content-Type：image / jpeg Content-Transfer-Encoding：binary

我们一直在想弄清楚如何将Content-ID添加到此请求中 . 这次电话会有什么明显的遗漏吗？有另一种方法来构建此请求吗？谢谢你的建议！
