Content-ID: <image>

......JPEG Binary Code Here.....

How can I get the Image(binary) from the response.

InputStream is = response.getEntity().getContent();

(InputStream)is contains boundary and content information also.

Content-Transfer-Encoding: binary
Content-ID: <image>

......JPEG Binary Code Here.....

--simple_boundary

How can I get pure Image binary data. And it's possible??

Bitmap bitmap = BitmapFactory.decodeStream((InputStream) response.getEntity().getContent());

Answer 2

您需要一个 http 解析器来读取消息正文。

Answer 3

请求内容被拆分和编码，因此处理起来并不容易。

几年前我使用Apache Commons FileUpload来处理这种请求（ei multipart），这个库大大简化了这个过程。

在入门部分，您可以找到几个示例。
