在从嵌入式Applet进行HTTP调用时绕过内置浏览器身份验证 [英] Bypassing built-in browser authentication when making HTTP calls from embedded Applet

问题描述

• 我有一个简单的网页，包含
  嵌入式Java小程序。


• 小程序
  向所有共享相同
  身份验证（例如用户名，
  密码）的不同Axis
  摄像机发出HTTP调用。 / li>
  
• 我在启动小程序时将用户名和密码传递给Java代码 - 没有问题。


• 当我从NetBeans


• 当我在网络浏览器（Firefox）中打开HTML页面时，问题就开始了。
>


• 即使我的代码处理认证：

    URL u = new URL（useMJPGStream？ mjpgURL：jpgURL）; 
   huc =（HttpURLConnection）u.openConnection（）; 
   
   
   String base64authorization = 
   securityMan.getAlias（this.securityAlias）.getBase64authorization（）; 
   //如果需要授权设置与编码的连接
   //授权信息
   if（base64authorization！= null）
   {
   huc.setDoInput真正）; 
   huc.setRequestProperty（Authorization，base64authorization）; 
   huc.connect（）; 
  } 
   
   InputStream is = huc.getInputStream（）; 
   connected = true; 
   BufferedInputStream bis = new BufferedInputStream（is）; 
   dis = new DataInputStream（bis）; 
    



• 浏览器仍会显示身份验证弹出窗口，并分别请求每个摄像机的用户名和密码！


• 更糟糕的是，从相机显示的图片会冻结和过去（从昨晚起）。


• 如何绕过浏览器的身份验证 / p>
  
  

  我添加了以下行：

    huc.setDoOuput ; 
   huc.setUseCaches（false）; 
   
   
   
  之后的
    
   
   
    huc.setDoInput（true）; 
    

  行。

  
  
  • I have a simple web page with an embedded Java applet.
  • The applet makes HTTP calls to different Axis Cameras who all share the same authentication (e.g. username, password).
  • I am passing the user name and password to the Java code upon launch of the applet - no problem.
  • When I run from within NetBeans with the applet viewer, I get full access to the cameras and see streaming video - exactly as advertised.
  • The problem begins when I open the HTML page in a web browser (Firefox).

  • Even though my code handles authentication:

    URL u = new URL(useMJPGStream ? mjpgURL : jpgURL);
    huc = (HttpURLConnection) u.openConnection();
    
    
    String base64authorization = 
        securityMan.getAlias(this.securityAlias).getBase64authorization();
    // if authorization is required set up the connection with the encoded 
    // authorization-information
    if(base64authorization != null)
    {
        huc.setDoInput(true);
        huc.setRequestProperty("Authorization",base64authorization);
        huc.connect();
    }
    
    InputStream is = huc.getInputStream();
    connected = true;
    BufferedInputStream bis = new BufferedInputStream(is);
    dis= new DataInputStream(bis);
    

  • The browser still brings up an authentication pop-up and requests the username and password for each camera separately!
  • To make things worse, the images displayed from the camera are frozen and old (from last night).
  • How can I bypass the browser's authentication?

  解决方案

  Fixed

  I added the following lines:

  huc.setDoOuput(true);
  huc.setUseCaches(false);
  

  after the

  huc.setDoInput(true);
  

  line.
