Question

我绝对不是电脑大师。：）

尝试通过applet在我的网站上传文件时出现http 403错误。这意味着它是被禁止的。也许这是一种常规行为，可能不允许通过http协议上传。这是真的吗？那怎么办呢？我希望我的applet能够在服务器的特定文件夹上上传小文件。

这是代码：

private static String folder = "http://..." //URL of the folder to upload to        

public void saveScore(Item hs) { //Item is a serializable object to save

    String filename = "s"+Integer.toString(hs.getScore())+".sco" ; // name of the file

    System.out.println("*** Trying to save file to : " + filename) ;

    try {
        //setting connection
        HttpURLConnection con =  (HttpURLConnection) new URL(folder+"/"+filename).openConnection() ;
        con.setDoInput(true); 
        con.setDoOutput(true);
        con.setRequestProperty ("Content-Type", "multipart/form-data");
        con.setRequestProperty("User-Agent", "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9.2.2) Gecko/20100316 Firefox/3.6.2");
        con.setChunkedStreamingMode(1024);
        con.setRequestMethod("PUT") ;       
        ObjectOutputStream oos = new ObjectOutputStream(con.getOutputStream()) ;

        //uploading
        oos.writeObject(hs) ;

        oos.flush() ;
        oos.close();

        //getting answer
        DataInputStream is = new DataInputStream(con.getInputStream()); 
        String s = is.readLine(); 
        is.close(); 

        System.out.println("** Answer **");
        System.out.println(s) ;

    } catch (IOException e) {
        e.printStackTrace(System.out) ; // gives me a 403 error
    }

}

感谢您的帮助...
