Question

我试图向一个网络服务机构发送图像文件。

我的守则如下:

   ConnectionFactory connFact = new ConnectionFactory();
        ConnectionDescriptor connDesc;

        //String value = new String(data);
        String value= Base64OutputStream.encodeAsString(data, 0, data.length, false, false);

        value = "imgData=" + value;

        connDesc = connFact.getConnection("http://localhost:50806/Send");
        int iResponseCode = 0;
        HttpConnection httpConn = null;
        OutputStream os = null;
        if (connDesc != null)
        {

            try
            {
             byte[] theByteArray = value.getBytes();

                httpConn = (HttpConnection)connDesc.getConnection();

                httpConn.setRequestProperty("Content-Type", "image/jpeg");
                httpConn.setRequestMethod(HttpConnection.POST);
                httpConn.setRequestProperty("Content-Disposition", "form-data");
                httpConn.setRequestProperty("Connection", "Keep-Alive");
                httpConn.setRequestProperty("Content-Length", String.valueOf(data.length));

                //os = httpConn.openOutputStream();
                //os.write(theByteArray);
                DataOutputStream printout = new DataOutputStream (httpConn.openOutputStream()); 
                printout.write(theByteArray);
                iResponseCode = httpConn.getResponseCode();        
             } 
            catch(Exception e){
                e.printStackTrace();
            }
            finally{
                if(os != null)
                    os.close();

                if(httpConn != null){                    
                 httpConn.close();
                }
            }

        }
  return Integer.toString(iResponseCode);

一种星体表示,图像档案已输入该方法。

服务签署:

   [AcceptVerbs(HttpVerbs.Post)]  
    public ActionResult Send(string imgData)
    {}

任何关于如何发出这种看法的想法?

Thanks so much, Dan

基地64号编码的座标可能太大,无法在GET申请中作为URL参数通过。无论是该装置还是某种代理方式,都可能与请求不符。采用长期合作行动倡议的要求,这将更加安全。为此,将请求定为一份载有<条码>的持久性有机污染物(http://www.un.org/Depts/dpa/index.htm>的持久性有机污染物(http://www.un.org/chinese/sc/presidency.htm)的持久性有机污染物清单。 (可能的话,PostData 。)
