Интеграция Tableau с веб-проектом ⇐ JAVA

[Anonymous]

Я выполняю интеграцию Tableau с веб-проектом, используя API Java-скрипта. Я настроил свой IP-адрес на сервере таблиц с помощью commnad: tabadmin set wgserver.trusted_hosts "" и соответствующих команд. Но я не могу получить билет, в итоге получил -1. Я выполнил все шаги настройки.

Код: Выделить всё

 public class TableauServlet extends javax.servlet.http.HttpServlet {
private static final long serialVersionUID = 1L;

public TableauServlet() {
super();
}

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
final String user = "raghu";
final String wgserver = "103.xxx.xxx.xx";
final String dst = "views/Regional/College?:iid=1";
final String params = ":embed=yes&:toolbar=yes";

String ticket = getTrustedTicket(wgserver, user, request.getRemoteAddr());

if ( !ticket.equals("-1") ) {
response.setStatus(HttpServletResponse.SC_MOVED_TEMPORARILY);
response.setHeader("Location", "http://" + wgserver + "/trusted/" + ticket + "/" + dst + "?" + params);
}
else
// handle error
throw new ServletException("Invalid ticket " + ticket);
}

// the client_ip parameter isn't necessary to send in the POST unless you have
// wgserver.extended_trusted_ip_checking enabled (it's disabled by default)
private String getTrustedTicket(String wgserver, String user, String remoteAddr)
throws ServletException
{
OutputStreamWriter out = null;
BufferedReader in = null;
try {
// Encode the parameters
StringBuffer data = new StringBuffer();
data.append(URLEncoder.encode("username", "UTF-8"));
data.append("=");
data.append(URLEncoder.encode(user, "UTF-8"));
data.append("&");
data.append(URLEncoder.encode("client_ip", "UTF-8"));
data.append("=");
data.append(URLEncoder.encode(remoteAddr, "UTF-8"));

// Send the request
URL url = new URL("http://" + wgserver + "/trusted");
URLConnection conn = url.openConnection();
conn.setDoOutput(true);
out = new OutputStreamWriter(conn.getOutputStream());
out.write(data.toString());
out.flush();

// Read the response
StringBuffer rsp = new StringBuffer();
in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String line;
while ( (line = in.readLine()) != null) {
rsp.append(line);
}

return rsp.toString();

} catch (Exception e) {
throw new ServletException(e);
}
finally {
try {
if (in != null) in.close();
if (out != null) out.close();
}
catch (IOException e) {}
}
}
