使用BlackBerry上传图片 [英] Upload Image using blackberry

问题描述

我要上传使用MultipartPostData在BlackBerry模拟器的图像，下面是我的code，但它似乎并没有工作。我也签署了我的.cod文件。谁能帮我吗？

 公共无效POSTDATA（字符串URL，字节[]数据）
{
 如果（DeviceInfo.isSimulator（））{
 URL = URL +; deviceSide =真正的;
}
的HttpConnection httpConn = NULL;
OutputStream的OS = NULL;
InputStream为= NULL;
字符串URL =网址;
尝试{
   形式的PostData =新MultipartPostData（MultipartPostData.DEFAULT_CHARSET，FALSE）;
   字节[] = POSTDATA数据;
form.setData（POSTDATA）;      httpConn =（HttpConnection的）Connector.open（URL）;
      httpConn.setRequestMethod（HttpConnection.POST）;
   httpConn.setRequestProperty（用户代理，黑莓）;
   httpConn.setRequestProperty（内容类型，多部分/表单数据）;
   httpConn.setRequestProperty（MIME类型，图像/ JPEG）;
      httpConn.setRequestProperty（HttpProtocolConstants.HEADER_CONTENT_LENGTH，将String.valueOf（postData.length））;
      httpConn.setRequestProperty（内容语言，EN-US）;      OS = httpConn.openOutputStream（）;
      os.write（form.getBytes（））;    //读取响应
    StringBuffer的SB =新的StringBuffer（）;
    是= httpConn.openDataInputStream（）;
    INT CHR;
    而（（CHR = is.​​read（））！=  -  1）
      sb.append（（char）的CHR）;    的System.out.println（结果................................+ sb.toString（））;
    字符串结果= sb.toString（）;
}
赶上（例外五）
{
    的System.out.println（e.toString（））;
}
最后{
    尝试{
        如果（是！= NULL）
          is.close（）;
        如果（OS！= NULL）
          os.close（）;
如果（httpConn！= NULL）
 httpConn.close（）;
 }赶上（例外E1）{
        的System.out.println（e1.toString（））;
    }
   }
 }
 

解决方案

//你必须有一个bundary格式后的数据，.cod文件必须在模拟器上工作。

  httpConn =（HttpConnection的）connDesc.getConnection（）;
                httpConn.setRequestMethod（HttpConnection.POST）;
    httpConn.setRequestProperty（用户代理，黑莓）;
    httpConn.setRequestProperty（内容类型，的multipart / form-data的;边界= ---------- V2ymHFg03ehbqgZCaKO6jy）;            OS = httpConn.openOutputStream（）;
            //os.write（form.getBytes（））;            字节[] = fileBytes {1,2,3,4}; //获取文件的字节用自己的code            ByteArrayOutputStream BOS =新ByteArrayOutputStream（）;            bos.write（。（\\ r \\ N--+---------- V2ymHFg03ehbqgZCaKO6jy+\\ r \\ n）的getBytes（））;
       bos.write（（内容处置：表格数据;名称= \\mifoto \\;文件名= \\leo.gif \\\\ r \\ n）的getBytes（））;
       bos.write（（内容类型：image / GIF \\ r \\ n \\ r \\ n）的getBytes（））;
            bos.write（fileBytes）;
       bos.write（（\\ r \\ N--+---------- V2ymHFg03ehbqgZCaKO6jy+ -  \\ r \\ n）的getBytes（））;            os.write（bos.toByteArray（））;
 

I want to upload an image in blackberry simulator using MultipartPostData, the following is my code but it does not seem to work. I have also signed my .cod file. Can anyone help me please?

public void postData(String Url, bytes[] data)
{
 if (DeviceInfo.isSimulator()){
 Url=Url+";deviceSide=true";
}
HttpConnection httpConn=null;
OutputStream os=null;
InputStream is=null;
String url=Url;
try {
   PostData form = new MultipartPostData(MultipartPostData.DEFAULT_CHARSET, false) ;
   byte [] postData = data;
form.setData(postData);

      httpConn = (HttpConnection) Connector.open(url);
      httpConn.setRequestMethod(HttpConnection.POST);
   httpConn.setRequestProperty("User-Agent", "BlackBerry");
   httpConn.setRequestProperty("Content-Type", "multipart/form-data");
   httpConn.setRequestProperty("MIME-Type", "Image/Jpeg");
      httpConn.setRequestProperty(HttpProtocolConstants.HEADER_CONTENT_LENGTH, String.valueOf(postData.length));
      httpConn.setRequestProperty("Content-Language", "en-US");

      os =httpConn.openOutputStream();
      os.write(form.getBytes());

    //read response
    StringBuffer sb = new StringBuffer();
    is = httpConn.openDataInputStream();
    int chr;
    while ((chr = is.read()) != -1)
      sb.append((char) chr);

    System.out.println("Result................................ " + sb.toString());
    String result=sb.toString();
}
catch(Exception e)
{
    System.out.println(e.toString());
}
finally {
    try{
        if(is!= null)
          is.close();
        if(os != null)
          os.close();
if(httpConn != null)
 httpConn.close();
 } catch(Exception e1){
        System.out.println(e1.toString());
    }
   }
 }

解决方案

//you must have a bundary format post data, the .cod file must be work on the simulator

httpConn = (HttpConnection)connDesc.getConnection();
                httpConn.setRequestMethod(HttpConnection.POST);          
    httpConn.setRequestProperty("user-agent", "BlackBerry");    
    httpConn.setRequestProperty("content-type", "multipart/form-data; boundary=----------V2ymHFg03ehbqgZCaKO6jy");

            os = httpConn.openOutputStream();
            //os.write(form.getBytes());

            byte[] fileBytes = {1,2,3,4}; //retrieve file bytes with your own code                

            ByteArrayOutputStream bos = new ByteArrayOutputStream();

            bos.write(("\r\n--" + "----------V2ymHFg03ehbqgZCaKO6jy" + "\r\n").getBytes());
       bos.write(("Content-Disposition: form-data; name=\"mifoto\"; filename=\"leo.gif\"\r\n").getBytes());
       bos.write(("Content-Type: image/gif\r\n\r\n").getBytes());
            bos.write(fileBytes);
       bos.write(("\r\n--" + "----------V2ymHFg03ehbqgZCaKO6jy" + "--\r\n").getBytes());

            os.write(bos.toByteArray());
