Question

我是expressjs的新手，所以，我正在开发一个app，我需要在url中输入用户名。我不知道如何添加它。所以我在路由中有2个文件，其中包含以下代码

exports.user = function (req, res) {
sess = req.session;
if (sess.cocoToken != undefined || sess.cocoToken != null) {
    client.get(baseUrl + "/feed/", {headers: {"Authorization": "Token " + sess.cocoToken}}, function (data3, response3) {
        if (response3.statusCode == 200) {
            req.session.items = data3;

            client.get(baseUrl + "/api/advice/", {headers: {"Authorization": "Token " + sess.cocoToken}}, function (data4, response4) {
                if (response4.statusCode == 200) {
                    req.session.items = data4;
                    res.render('user', {
                        title: req.session.profile.username,
                        classname: 'feed',
                        profile: req.session.profile,
                        feedIitems: req.session.items,
                        advices: req.session.items
                    });
                }
            });
        }
    });

    console.log(req.session.profile);
} else {
    res.redirect("/logout")
}

};

在app.js中我调用路径

app.get('/user', routes.user);

现在如何将用户名放在网址中？

Answer 1

你可以通过

来完成

req.param('tagId')

Answer 2

您可以将用户名作为查询参数传递，因为这是一个GET请求，例如http://example.com/user?username=user2991920。

在您的路线中，您可以使用req.query.username

访问它

exports.user = function(req, res) {
    // req.query.username will have query username
}

您无需修改app.get('/user', routes.user);

Answer 3

app.get('/user/:id', function (req, res) {
sess = req.session;
if (sess.cocoToken != undefined || sess.cocoToken != null) {
    client.get(baseUrl + "/api/user/" + req.params.id + "/", {headers: {"Authorization": "Token " + sess.cocoToken}}, function (user, response3) {
        if (response4.statusCode == 200) {
            req.session.items = advices;
            res.render('user', {
                title: user.profile.username,
                classname: 'feed',
                user: user
            });
        }

    });
}

}）;
