Express将重定向发送页面作为数据转换为angular $ http成功,而不是重定向到页面

Question

当用户通过验证客户端获取的页面内容home.html中result,而不是重定向到home.html.

客户端电话:

$http({
method: "post",
url: "http://localhost:2222/validateUser",
data: {
    username: $scope.username,
    password: $scope.password
}

}).then(function (result) {
    if (result.data && result.data.length) {
        alert('User validated');
    } else {
        alert('invalid user');
    }
});

服务器端控制器方法:

module.exports.validateUser = function (req, res) {
  User.find({ 'username': req.body.username, 'password': req.body.password }, function (err, result) {
    if (result.length) {
        req.session.user = result[0]._doc;
        res.redirect('/home');
    }else{
        res.json(result);
    }
  });
};

在app.js中路由:

app.get('/home', function (req, res) {
    var path = require('path');
    res.sendFile(path.resolve('server/views/home.html'));
});

您可以将重定向逻辑移至客户端。

客户：

$http({
    method: "post",
    url: "http://localhost:2222/validateUser",
    data: {
        username: $scope.username,
        password: $scope.password
    },
}).then(function (result) {
    alert('user validated');
    window.location.replace('/home');
}).catch(function(result) {
    alert('login failed');
});

服务器：

module.exports.validateUser = function (req, res) {
  User.find({ 'username': req.body.username, 'password': req.body.password }, function (err, result) {
    if (result.length) {
        req.session.user = result[0]._doc;
        res.send('OK');
    } else {
        // responding with a non-20x or 30x response code will cause the promise to fail on the client.
        res.status(401).json(result);
    }
  });
};
