Curl对象到URL的生成

我正在尝试调用Web服务：

以下卷曲命令适用于该

    curl -F fa=c.apiupload -F sessiontoken=EA3237F922644115A0F7DB75D0AE388F -F destfolderid=52482BD488DB4AD6887C5C7BF47BD6FC -F filedata=@/Users/cpinera/tmp/panda2.jpg -F zip_extract=1 -F metadata=1 -F meta_img_description="This is a very nice panda" -F meta_img_keywords="panda,happy panda" http://domain.com/razuna/raz1/dam/index.cfm

但是作为访问RESTFul API的HttpURLConnection，我生成的等价URL不是：

 http://domain.com/razuna/raz1/dam/index.cfm?fa=c.apiupload&sessiontoken=F46D2226463C4ADE866819AACD7D2F5E&filedata=C:'JobInterview'BatchUpload'auth.xml&destfolderid=52482BD488DB4AD6887C5C7BF47BD6FC&zip_extract=1

我收到REST请求的响应：

   The content was :: <?xml version="1.0" encoding="UTF-8"?><Response><responsecode>1</responsecode><message>Upload failed This was not an uploaded form type</message></Response>

这是Java代码

使用查询URL的方法：

public static String doQuery(String loginUrl) throws IOException{
    URL url = new URL(loginUrl);
    HttpURLConnection conn =
          (HttpURLConnection) url.openConnection();
      conn.setRequestMethod("POST");
      if (conn.getResponseCode() != 200) {
        throw new IOException(conn.getResponseMessage());
      }

      InputStream is = conn.getInputStream();
      //Buffer the result into a string
      BufferedReader rd = new BufferedReader(
          new InputStreamReader(is));
      StringBuilder sb = new StringBuilder();
      String line;
      while ((line = rd.readLine()) != null) {
         line = StringEscapeUtils.unescapeHtml4(line); 
        sb.append(line);
      }
      rd.close();
      conn.disconnect();
      System.out.println("The content was :: " + sb.toString());
      return sb.toString();
}

应上传的方法：

  public static void testUpload(String seesionToken, String file ) throws IOException{
    String upload = "http://domain.com:8080/razuna/raz1/dam/index.cfm?fa=c.apiupload&sessiontoken="+seesionToken+"&filedata="+file+"&destfolderid=52482BD488DB4AD6887C5C7BF47BD6FC&zip_extract=1" ;
    System.out.println(upload);
    Authenticate.doQuery(upload);
}

在doQuery中添加后：conn.setRequestProperty（"内容类型"，"多部分/表单数据"）；

并将RESTFul URL更改为：

       http://domain.com:8080/razuna/raz1/dam/index.cfm?fa=c.apiupload&sessiontoken="+seesionToken+"&filedata="+files.toURI()+"&destfolderid=52482BD488DB4AD6887C5C7BF47BD6FC&zip_extract=1"

它似乎检测到URL正在尝试发送文件，但仍然无法上传文件：

        The content was :: <?xml version="1.0" encoding="UTF-8"?><Response><responsecode>1</responsecode><message>Upload failed There was no appropriate FILE found in the upload</message></Response>
