Question

＆＃39; /故事＆＃39;页面是特定于用户的，需要有效的登录凭据。

在重定向之前，节点，服务器端和正确日志会进行验证，但不会重定向到故事页面。

这似乎是因为＆＃34; You can't make a redirection after an AJAX. You need to do it yourself in Javascript＆＃34;，但这个问题的第一个答案中的代码似乎有点不完整..对于成功通话..

此外，如何在重定向后成功调用后续函数（refreshStories）？

这是AJAX：

if (loginUsername.length != 0) {
  console.log('there is a login: ' + loginUsername);
    // make an ajax call
    $.ajax({
    dataType: 'json',
    data: AjaxLoginData,
    type: 'post',
      url:"http://localhost:4200/api/v1/users",
      success: (data, textStatus, jqXHR) ->
          if typeof data.redirect == 'string'
              window.location = data.redirect
      success: refreshStories,
      error: foundError
    });

Node.js + Express4

router.route('/users')

    // log in a user (accessed at POST http://localhost:4200/api/v1/users)
    .post(function(req, res) {

      var username = req.body.loginUsername;
      var password = req.body.loginPassword;

      authenticateUser(username, password, function(err, user){
      console.log('authenticate user..');
        if (user) {
          console.log('yes user');
          // subsequent requests will know the user is logged in
          req.session.username = user.username;
          console.log('set session username to: ' + req.session.username);

          // res.redirect('/stories');
                res.send({redirect: '/stories'});
          console.log('user logged in .. redirect to stories');

        } else {
          console.log('user authentication badCredentials error..');
          res.render('index', {badCredentials: true});
        }
      });
    });

试试这个

if (loginUsername.length != 0) {
  console.log('there is a login: ' + loginUsername);
    // make an ajax call
    $.ajax({
    dataType: 'json',
    data: AjaxLoginData,
    type: 'post',
      url:"http://localhost:4200/api/v1/users",
      success: (data, textStatus, jqXHR) ->
          if (typeof data.redirect == 'string')
              window.location.replace(window.location.protocol + "//" + window.location.host + data.redirect);
      error: foundError
    });

window.location.replace（...）将最好地模拟HTTP重定向 How to redirect to another webpage in JavaScript/jQuery?

对于您的刷新故事＆＃39;这些东西，你应该只是在去故事＆＃39;

时刷新故事

Node.js页面重定向AJAX登录？重定向后调用函数？
