Node.js passport本地策略在邮递员中工作，但不在浏览器中工作

我正在尝试使用电子邮件和密码设置身份验证。下面是signup.ejs中的部分代码：

<% if (message.length > 0) { %>
        <div class="alert alert-danger"><%= message %></div>
    <% } %>

    <!-- LOGIN FORM -->
    <form action="/signup" method="post">
        <div class="form-group">
            <label>Email</label>
            <input type="text" class="form-control" name="email">
        </div>
        <div class="form-group">
            <label>Password</label>
            <input type="password" class="form-control" name="password">
        </div>

        <button type="submit" class="btn btn-warning btn-lg">Signup</button>
    </form>

这是我正在使用的本地护照策略：

passport.use(
        'local-signup',
        new LocalStrategy(
            {
                // by default, local strategy uses username and password, we will override with email
                usernameField: 'email',
                passwordField: 'password',
                passReqToCallback: true // allows us to pass back the entire request to the callback
            },
            function(req, email, password, done) {
                // asynchronous
                // User.findOne wont fire unless data is sent back
                process.nextTick(function() {
                    // find a user whose email is the same as the forms email
                    // we are checking to see if the user trying to login already exists
                    User.findOne({ 'local.email': email }, function(err, user) {
                        // if there are any errors, return the error
                        if (err) return done(err)

                        // check to see if theres already a user with that email
                        if (user) {
                            return done(
                                null,
                                false,
                                req.flash('signupMessage', 'That email is already taken.')
                            )
                        } else {
                            // if there is no user with that email
                            // create the user
                            var newUser = new User()

                            // set the user's local credentials
                            newUser.local.email = email
                            newUser.local.password = newUser.generateHash(password)

                            // save the user
                            newUser.save(function(err) {
                                if (err) throw err
                                return done(null, newUser)
                            })
                        }
                    })
                })
            }
        )
    )

我遇到的问题是，当我在请求正文中使用电子邮件和密码向邮递员发出post请求时，结果很好，我成功地重定向到配置文件路径。但是，当我试图通过填写页面上的表单登录时，我会被重定向回“/signup”路径。有人能帮我解决这个问题吗？

我找到了答案。原因是表单没有将电子邮件和密码值传递给req.body。我将app.usebodyParser.json更改为app.usebodyParser.urlencoded{extended:true}，它开始工作。

一般提示：检查并查看是否调用了策略的验证处理程序。检查并查看电子邮件和密码是否包含预期值。检查并查看是否出现任何错误。

                usernameField: 'email',
                passwordField: 'password',
                passReqToCallback: true // allows us to pass back the entire request to the callback
