如何在BlackBerry上的服务器上上传图片？

-1

我是黑莓开发新手，我必须将设备库中的图片上传到服务器。我发现很多与此相关的链接。但是我找不到这个问题的确切结果。我用这个Example。使用这个例子，我得到了Byte []的值，但我无法使用此代码满足我的要求。因为我无法理解我们必须在代码中传递哪个URL以及哪些参数。如何在BlackBerry上的服务器上上传图片？

我使用了一种格式，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);

任何人都可以帮我吗？我困在此。

感谢，曼西

你检查这一点 - http://www.developer.nokia.com/Community/Wiki/HTTP_Post_multipart_file_upload_in_Java_ME？ – 2011-10-17 19:02:19

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();

您好，Vijay感谢您的回复但我有一个问题，在这一行“HttpConnection conn =（HttpConnection）Connector.open（Url，Connector.READ_WRITE）;”我们必须传递哪个网址以及哪些参数？你可以看到我的URL可以写吗？我们怎样才能生成它？谢谢 – anddev 2011-10-18 04:32:30

Url =“http://74.208.77.106/jm/testing/iDaddyapi.php?;deviceside=true;interface=wifi”; 你不添加“？”用于传递参数的Webservice名称之后。现在添加“？”然后再试一次。 – 2011-10-18 05:00:14
