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多部分请求的代码:
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;
这就是我们要求的网络服务所要求的:
<?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 =“签名” 内容类型:多部分/相关 用户代理:代理 内容长度:2336363 主持人:10.1.1.1 连接:Keep-Alive
- HPeiFlrswQmM8Mi1uoWpzJRfrnp3AMtZjpCdt 内容处理:表格数据; NAME = “体” Content-Type:application / xml;字符集= UTF-8 内容传输编码:8位
<?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 内容处理:表格数据; NAME = “test_image_cid”;文件名= “test_image_cid” 内容类型:image / jpeg 内容传输编码:二进制
我们一直在搞清楚如何将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!
答案 0 :(得分:4)
要添加Content-Id或任何其他字段,您必须使用FormBodyPart。简单地说,分开这些行:
ByteArrayBody bab = new ByteArrayBody( data, "image/jpeg", "test_image_cid" );
mpEntity.addPart( "body", body );
进入以下几行:
ByteArrayBody bab = new ByteArrayBody( data, "image/png", "byte_array_image" );
FormBodyPart fbp = new FormBodyPart( "form_body_name", bab );
fbp.addField( "Content-Id", "ID_GOES_HERE" );
mpEntity.addPart( fbp );
这应该适合你!
