Iterator (); String key; boolean first = true While (it.hasNext ()) {key = it.next (); sb.append (first?':'&'); sb.append (java.net.URLEncoder.encode (key, "UTF-8")); sb.append ('=') Sb.append (java.net.URLEncoder.encode (params.get (key). ToString (), "UTF-8"); first = false;} / / get the preview result URL, jump to URL url = new URL (sb.toString ()); DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance (); factory.setValidating (false); DocumentBuilder builder = factory.newDocumentBuilder () Document document = builder.parse (url.openStream ()); document.getDocumentElement (). Normalize (); Element root = document.getDocumentElement (); if (root.getAttribute ("success"). Equals ("true") {/ / Preview result URL String viewUrl = root.getElementsByTagName ("result"). Item (0). GetTextContent () / / Jump response.sendRedirect (viewUrl);} else {throw new RuntimeException (root.getElementsByTagName ("error"). Item (0).
