Question

我是Blackberry开发的新手，我必须将我的Image从设备库上传到服务器。我发现很多与此相关的链接。但我找不到这个问题的确切结果。我用了这个Example。使用这个例子，我得到了Byte []的值，但是我无法使用这段代码满足我的要求。因为我无法理解我们必须在代码中传递哪个URL以及哪些是参数。

我又使用了一种格式，我在这里发布我的代码，使用这个我得到了响应代码：200。但我无法解决这个问题

HttpConnection oCon = (HttpConnection)Connector.open("http://74.208.77.106/jm/testing/iDaddyapi.php;deviceside=true;interface=wifi");
                 oCon.setRequestMethod(HttpConnection.POST);
                 oCon.setRequestProperty("Content-Length", "" + imageByte.length);

                 URLEncodedPostData oPostData = new URLEncodedPostData(URLEncodedPostData.DEFAULT_CHARSET, false);

                 oPostData.append("api", "postidaddyimage");
                 oPostData.append("imagetype", "F");
                 oPostData.append("image", strImage);

                 OutputStream strmOut = oCon.openOutputStream();
                 strmOut.write(oPostData.getBytes());

                 strmOut.flush();
                 strmOut.close();



     int rc = oCon.getResponseCode();
     System.out.println("Response code.............."+rc);
     if (rc != HttpConnection.HTTP_OK)
                     throw new IOException("Error response code: " + rc);

任何人都可以帮助我吗？我坚持这个。

谢谢，曼西

HttpConnection conn = (HttpConnection) Connector.open(Url, Connector.READ_WRITE);

conn.setRequestProperty(HttpProtocolConstants.HEADER_CONTENT_LENGTH,
            String.valueOf(imagedata.length));

conn.setRequestProperty("x-rim-transcode-content", "none");
ByteArrayOutputStream out = new ByteArrayOutputStream();
OutputStream finalOut = conn.openOutputStream();

String newLine = "\r\n";
out.write(newLine.getBytes());
out.write("--".getBytes());
out.write(boundary.getBytes());
out.write(newLine.getBytes());
String contDisp = "Content-Disposition:form-data;  
name=\"file\";filename=\"Image.jpg\"";
String contEnc = "Content-Transfer-Encoding: binary";
String type = "Content-Type:image/jpeg";
out.write(contDisp.getBytes());
out.write(newLine.getBytes());
out.write(type.getBytes());
out.write(newLine.getBytes());
out.write(contEnc.getBytes());
out.write(newLine.getBytes());
out.write(newLine.getBytes());
out.write(imagedata);
out.write(newLine.getBytes());
out.write("--".getBytes());
out.write(boundary.getBytes());
out.write("--".getBytes());
out.write(newLine.getBytes());
finalOut.write(out.toByteArray());

out.flush();
out.close();

finalOut.flush();
finalOut.close();
