I'm going through the
google app engine tutorials at https://developers.
google.com/appengine/docs/java/gettingstarted/usingusers
I'm very new to
google app engine, java and web programming in general. So my question is, at the bottom of the page it says to add a link to allow the user to log out. So far I've got this:
public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws IOException {
UserService userService = UserServiceFactory.getUserService();
User user = userService.getCurrentUser();
if(user != null){
resp.setContentType("text/plain");
resp.getWriter().println("Hello, " + user.getNickname());
String logoutLink = String.format("<a href=\"%s\">Click here to log out.</a>",
userService.createLogoutURL(req.getRequestURI()));
resp.getWriter().println(logoutLink);
}else {
resp.sendRedirect(userService.createLoginURL(req.getRequestURI()));
}
}
However instead of a link, the full string is printed to the screen including the tags. When I look at the page source, I have no tags or any of the other stuff that goes with a webpage. I guess that makes sense considering I've done nothing to output any of that. Do I just do a bunch of resp.GetWriter().println() statements to output the rest of the webpage, or is there something else I don't know about?
Thanks!
