Paypal SSLHandshakeException

Question

我正在實施paypal無聲帖子。這是一次工作，但現在似乎有問題。我得到的錯誤：

我使用的代碼關閉paypals的網站，這是建議的握手

// Take the request and get the query string 
    // Read post from PayPal system and add 'cmd' 
    Enumeration en = request.getParameterNames(); 
    String str = "cmd=_notify-validate"; 
    while (en.hasMoreElements()) { 
     String paramName = (String) en.nextElement(); 
     String paramValue = request.getParameter(paramName); 
     str = str + "&" + paramName + "=" + URLEncoder.encode(paramValue, "UTF-8"); 
    } 

    String gateway = "https://www.sandbox.paypal.com/cgi-bin/webscr"; 

    // Post back vars to paypal to validate this transaction 
    URL u = new URL(gateway); 
    URLConnection uc = u.openConnection(); 
    uc.setDoOutput(true); 
    uc.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); 
    try { 
     PrintWriter pw = new PrintWriter(uc.getOutputStream()); 
     pw.println(str); 
     pw.close(); 
    } catch (IOException ex) { 
     Logger.getLogger(PaypalServlet.class.getName()).log(Level.SEVERE, null, ex); 
    } 

Answer 1

一個解決方案，我發現這是：

urlCon.setHostnameVerifier(new HostnameVerifier() { 
    @Override 
    public boolean verify(String hostname, SSLSession session){ 
     return true; 
    } 
}); 

如果它不起作用，請嘗試使用HttpsURLConnection而不是URLConnection。
