## Description
|
||
<section id="description">提醒一下，这个项目是基于<a href="https://glitch.com/#!/import/github/freeCodeCamp/boilerplate-advancednode/">Glitch</a>的以下入门项目构建的，或者是从<a href="https://github.com/freeCodeCamp/boilerplate-advancednode/">GitHub</a>克隆的。现在我们需要允许我们网站上的新用户注册一个帐户。在主页的res.render上，向传递的对象添加一个新变量 - <code>showRegistration: true</code> 。刷新页面时，您应该会看到已在index.pug文件中创建的注册表单！此表单设置为<b>POST</b> on <em>/ register，</em>因此我们应该设置此接受POST并在数据库中创建用户对象。注册路由的逻辑应如下所示：注册新用户>验证新用户>重定向到/配置文件步骤1的逻辑，注册新用户，应如下所示：使用findOne命令查询数据库>如果用户返回然后它存在并重定向回到主页<em>或者</em>如果用户未定义且没有发生错误，则使用用户名和密码将“insertOne”输入数据库，只要没有错误发生，然后调用<em>next</em>转到步骤2，验证新的user，我们已经在POST / login路由中编写了逻辑。 <pre> app.route（ '/寄存器'）
|
||
.post（（req，res，next）=> {
|
||
db.collection（'users'）。findOne（{username：req.body.username}，function（err，user）{
|
||
if（错误）{
|
||
下一个（ERR）;
|
||
} else if（user）{
|
||
res.redirect（ '/'）;
|
||
} else {
|
||
db.collection（ '用户'）。insertOne（
|
||
{username：req.body.username，
|
||
密码：req.body.password}，
|
||
（错误，doc）=> {
|
||
if（错误）{
|
||
res.redirect（ '/'）;
|
||
} else {
|
||
next（null，user）;
|
||
}
|
||
}
|
||
）
|
||
}
|
||
}）}，
|
||
passport.authenticate（'local'，{failureRedirect：'/'}），
|
||
（req，res，next）=> {
|
||
res.redirect（ '/简档'）;
|
||
}
|
||
）; </pre>当您认为自己已经做对时，请提交您的页面。如果您遇到错误，可以<a href="https://gist.github.com/JosephLivengood/6c47bee7df34df9f11820803608071ed">在这里查看</a>到目前为止完成的项目。 </section>
