上傳圖像到服務器使用黑莓http連接

-1

嗨下面是簡單的代碼上傳文件到服務器其工作正常...但是當我通過黑莓發送圖像到服務器它做了一些工作，但沒有圖像文件在服務器請指導我在那裏會犯錯......上傳圖像到服務器使用黑莓http連接

<html> 
<head> 
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> 
    <title></title> 
</head> 

<body> 
    <form enctype="multipart/form-data" method="post" action="img.php"> 
     <input type="file" name="image"/> 
     <input type="submit" name="upload"/> 
    </form> 
     </body> 
</html>

這裏是BB的Java代碼

public HttpMultipartRequest(String url, Hashtable params, Hashtable headers, String fileField, 
      String fileName, String fileType, byte[] fileBytes) 
      throws Exception { 

     this.url = url; 

     String boundary = getBoundaryString(); 

     String boundaryMessage = getBoundaryMessage(boundary, params, 
       fileField, fileName, fileType); 

     String endBoundary = "\r\n--" + boundary + "--\r\n"; 

     ByteArrayOutputStream bos = new ByteArrayOutputStream(); 

     bos.write(boundaryMessage.getBytes()); 

     bos.write(fileBytes); 

     bos.write(endBoundary.getBytes()); 

     this.postBytes = bos.toByteArray(); 

     bos.close(); 

    } 

    String getBoundaryString() { 
     return BOUNDARY; 
    } 

    String getBoundaryMessage(String boundary, Hashtable params, 
      String fileField, String fileName, String fileType) { 
     StringBuffer res = new StringBuffer("--").append(boundary).append(
       "\r\n"); 

     Enumeration keys = params.keys(); 

     while (keys.hasMoreElements()) { 
      String key = (String) keys.nextElement(); 
      String value = (String) params.get(key); 

      res.append("Content-Disposition: form-data; name=\"").append(key) 
        .append("\"\r\n").append("\r\n").append(value).append(
          "\r\n").append("--").append(boundary) 
        .append("\r\n"); 
     } 
     res.append("Content-Disposition: form-data; name=\"").append(
       fileField).append("\"; filename=\"").append(fileName) 
       .append("\"\r\n").append("Content-Type: ").append(fileType) 
       .append("\r\n\r\n"); 

     return res.toString(); 
    } 

    public byte[] send() 
    { 
     HttpConnection hc = null; 

     InputStream is = null; 

     ByteArrayOutputStream bos = new ByteArrayOutputStream(); 
     String login = test:test; 
     byte[] res = null; 

     boolean keepGoing = true; 
     boolean needAuth = false; 

     try { 
      byte[] encoded = Base64OutputStream.encode(login.getBytes(), 0, login.length(), false, false); 

      Logger.log("Trying to connect to "+url); 
      hc = (HttpConnection) Connector.open(url); 

      while (keepGoing) { 
       // headers needed specifically for upload 
       hc.setRequestProperty("Content-Type", 
         "multipart/form-data; boundary=" + getBoundaryString()); 
       hc.setRequestProperty(
         HttpProtocolConstants.HEADER_CONTENT_LENGTH, Integer 
           .toString(postBytes.length)); 
       hc.setRequestProperty("x-rim-transcode-content", "none"); 

       hc.setRequestProperty("Authorization", "Basic " + new String(encoded)); 


       hc.setRequestMethod(HttpConnection.POST); 

       OutputStream dout = hc.openOutputStream(); 


       dout.write(postBytes); 

       dout.close(); 

       int responseCode = hc.getResponseCode(); 
       if (responseCode == HttpConnection.HTTP_UNAUTHORIZED) { 
        hc.close(); 
        hc = (HttpConnection) Connector.open(url); 
        needAuth = true; 

        throw new Exception("Exception when uploading. RC: "+String.valueOf(responseCode)+", Unauthorized."); 

       } else if (responseCode == 422) { 
        throw new Exception("Exception when uploading. RC: "+String.valueOf(responseCode)+"."); 
       } else if (responseCode == HttpConnection.HTTP_OK) { 
        int ch; 
        bos.reset(); 

        is = hc.openInputStream(); 

        while ((ch = is.read()) != -1) { 
         bos.write(ch); 
        } 
        res = bos.toByteArray(); 

        keepGoing = false; 
       } else { 
        int ch; 
        bos.reset(); 
        is = hc.openInputStream(); 

        while ((ch = is.read()) != -1) { 
         bos.write(ch); 
        }

hey..few天前我也面臨同樣的問題，我通過以下鏈接解決問題：https：//github.com/cleverua/blackberry_multipart_post，也許這也會對你有所幫助 –

謝謝@Anzy_現在其真正的作品:) – AndroidNijx

@omer younus你可以發佈完整的解決方案，包括函數HttpMultipartRequest的調用爲例。我也需要幫助。你的解決方案將幫助我很多。謝謝。 – ejobity

前幾天，我面臨着同樣的問題，我現在整理出這個由以下的幫助link ...可能是這會幫助你.. !!!
