我尝试使用multipart post请求上传两个字符串参数（令牌和源）以及从移动设备捕获的图像（返回jpeg编码的byte []）。但它产生了错误，我确信这是由于不正确的请求。
我仍然不确定有关创建多部分帖子请求的注释。所以任何有用的链接和资源都会很好。
该代码适用于Blackberry Java开发

StringBuffer buffer = new StringBuffer();
String boundary = "--@#$--";
byte[] image = byte[] from camera.getsnapshot;
buffer.append(boundary+"\r\nContent-Disposition: form- data;name=\"token\"\r\n"+token+"\r\n");
buffer.append(boundary+"\r\nContent-Disposition: form- data;name=\"source\"\r\n"+"Blackberry"+"\r\n");
buffer.append(boundary+"\r\nContent-Disposition: form- data;name=\"file.jpg\";filename=\""+ "file.jpg"+"\""+"\n" + "Content- Type:image/jpeg"+"\n"+ "Content-Transfer-Encoding: binary" + boundary +"\r\n" +new String(image));
buffer.append("\r\n" + boundary + "\r\n");
String string = new String(buffer);
byte[] post = string.getBytes();
HttpConnection connection = (HttpConnection)Connector.open(url);
connection.setRequestMethod("POST");
connection.setRequestProperty(HttpProtocolConstants.HEADER_CONTENT_TYPE,
HttpProtocolConstants.CONTENT_TYPE_MULTIPART_FORM_DATA+
";boundary="+boundary);
connection.setRequestProperty(HttpProtocolConstants.HEADER_CONTENT_LENGTH,String.valueOf(post.length));
connection.setRequestProperty("User-Agent", "Profile/MIDP_2.0 Configuration/CLDC-1.0");
OutputStream postStream =connection.openOutputStream();
postStream.write(post,0,post.length);
postStream.close();
