Question

我正在尝试通过POST请求更新护照中的用户记录。我已经看过各种教程和之前对similar question的回答。我已经实现了以下代码：

var User = require("../models/user");

router.get("/settings/profile/:id", isLoggedIn, function(req,res){
    res.render("profile/profilesettings", {
        User: req.user
    });
});

router.post("/settings/profile/:id", isLoggedIn, function(req,res){
    User.update({_id: req.session.passport.user.id}, {
        email: req.body.email,
        imageUrl: req.body.imageUrl,
        bio: req.body.bio
    }, function (err){
        console.log(err);
    });
    res.render("profile/profilesettings", {
        User: req.user
    });
})

这是执行更新功能的表单。

<form class="form-horizontal" action="/settings/profile/<%= currentUser._id %>" method="POST">
        <div class="form-group">
            <label class="control-label col-sm-2" for="username">Username:</label>
            <div class="col-sm-10">
                <input type="text" class="form-control" id="username" name="username" placeholder="username" value="<%= currentUser.username %>" disabled>
            </div>
        </div>
        <div class="form-group">
            <label class="control-label col-sm-2" for="email">Email:</label>
            <div class="col-sm-10">
                <input type="text" class="form-control" id="email" name="email" placeholder="email" value="<%= currentUser.email %>">
            </div>
        </div>
        <div class="form-group">
            <label class="control-label col-sm-2" for="profileimage">Upload Image:</label>
            <div class="col-sm-10">
                <div class="input-group">
                    <span class="input-group-btn">
                        <span class="btn btn-default btn-file">
                            Browse.. <input type="file" id="profileimage">
                        </span>
                    </span>
                    <input type="text" class="form-control" id="profileimage" name="profileimage" placeholder="Profile Pic">
                </div>
            </div>
        </div>
        <div class="form-group">
            <label class="control-label col-sm-2" for="bio">Bio:</label>
            <div class="col-sm-10">
                <textarea class="form-control" rows="5" id="bio" name="bio" placeholder="Tell us about yourself!"><%= currentUser.bio %></textarea>
            </div>
        </div>
        <div class="form-group">
                    <div class="col-sm-offset-2 col-sm-10">
                        <button class="btn btn-lg btn-primary">Save Changes</button>
                    </div>
        </div>
    </form>

我还有以下isLoggedIn中间件：

    function isLoggedIn(req, res, next) {
    if (req.isAuthenticated()) {
        return next();
    }
    res.redirect("/login");
}

应用程序运行，但是当我单击“保存更改”时，将返回null结果，并且不会更新任何内容。

Answer 1

这是因为您在文档更新之前回复了请求。您应该在更新回调中移动您的响应（res.render(...）：

User.update({_id: req.session.passport.user.id}, {
        email: req.body.email,
        imageUrl: req.body.imageUrl,
        bio: req.body.bio
    }, function (err){
        if (err) console.log(err);
        res.render("profile/profilesettings", {
        User: req.user
    });
});

Answer 2

1）req.user._id和req.session.passport.user都相同。您可以改用req.user._id。

2）我的大部分护照申请都没有req.session.passport.user.id，而req.session.passport.user本身就是身份证。

3）尝试在回调中嵌套

router.post("/settings/profile/:id", isLoggedIn, function(req, res, next){
    User.update({ id: req.session.passport.user }, {
        email: req.body.email,
        imageUrl: req.body.imageUrl,
        bio: req.body.bio
    }, function(err, user) {
        if (err) return next(err);
        User.findById(req.user._id, function(err, user) {
            if (err) return next(err);
            return res.render('profile/profilesettings', {
                user:user
            });
        });
    });
});

在Passport + MongoDB中更新用户记录
