Question

我有一个登录表单如下：

<form action="urlLink/auth/signin" method="POST" class="signin form-horizontal" autocomplete="off">
    <fieldset>
        <div class="form-group">
            <!-- the email is expected as the username -->
            <label for="username">Email</label>
            <input type="text" id="username" name="username" class="form-control" data-ng-model="credentials.username" placeholder="Username">
        </div>
        <div class="form-group">
            <label for="password">Password</label>
            <input type="password" id="password" name="password" class="form-control" data-ng-model="credentials.password" placeholder="Password">
        </div>
        <div class="text-center form-group">
            <button type="submit" id="submitbtn">Login</button>
        </div>
    </fieldset>
</form>

使用“urlLink / auth / signin”登录后，应将其重定向到另一个页面（“urlLink”），但是在正确登录后我只能获得一个json对象。

登录代码我使用node.js和passport.js。我的登录代码如下：

exports.signin = function(req, res, next) {
passport.authenticate(['ldapauth', 'local'], function(err, user, info) {
    console.log("user in auth is " + JSON.stringify(user.username));
    if (err || !user) {
        res.status(400).send(info);
    } else {
        req.login(user, function(err) {
            if (err) {
                res.status(400).send(err);
            } else {
                // update user if in status created and a login has happend
                if (user.status === "created") {
                    // use an update because of the pre-code run on each user.save
                    user.status = "registered";
                    user.updated = Date.now();
                    User.update({_id:user._id}, {$set: {status: user.status, updated:user.updated}}, function(err) {
                        if (err) {
                            return res.status(400).send({
                                message: errorHandler.getErrorMessage(err)
                            });
                        } else {
                            // Remove sensitive data before login
                            user.password = undefined;
                            user.salt = undefined;
                            res.json(user);
                        }
                    });
                } else {
                    // Remove sensitive data before login
                    user.password = undefined;
                    user.salt = undefined;
                    res.json(user);
                }
            }
        });
    }
})(req, res, next);
};

如何将其正确重定向到目标网页？使用JQuery，Ajax，....请帮忙！

也许是这样的（假设包含jQuery）：

<script>
  $('#submitbtn').on('click', function(e){
    e.preventDefault();
    var data = { username:$('#username').val(), password:$('#password').val() };
    $.post(
      $('form.signin').attr('action'),
      data,
      function(res){
        //check your console (F12) to see what is returned from the page - take this out for production
        console.log(res);

        //based on the status you can redirect
        if(res.status == 'registered'){
          window.location = 'urlLink';

          //if you are given a unique id for the user from the server
          //you can append it to the URL too, if necessary - usually
          //something like this is needed, or else someone could look at your
          //JS, and say oh, well I'll just change the filename to urlLink
          //window.location = 'urlLink?userid=' + res._id;
        }
        else{
          alert("Account not registered.");
          //window.location = 'noAuth';
        }
      }
    );
  });
</script>
