## Description
|
|||
|
<section id="description">提醒一下,这个项目是基于<a href="https://glitch.com/#!/import/github/freeCodeCamp/boilerplate-socketio/">Glitch</a>的以下入门项目构建的,或者是从<a href="https://github.com/freeCodeCamp/boilerplate-socketio/">GitHub</a>克隆的。目前,您无法确定谁连接到您的Web套接字。虽然'req.user'对用户对象进行了容器处理,但只有当您的用户与Web服务器进行交互并且使用Web套接字时,您才没有req(请求),因此没有用户数据。解决知道谁连接到您的Web套接字的问题的一种方法是解析和解码包含护照会话的cookie,然后对其进行反序列化以获取用户对象。幸运的是,NPM上有一个包,只是为了将一次复杂的任务变成简单的事情! <hr>将“passport.socketio”添加为依赖项,并将其命名为“passportSocketIo”。现在我们只需要告诉Socket.IO使用它并设置选项。确保在现有套接字代码之前添加它,而不是在现有连接侦听器中添加。对于您的服务器,它应如下所示: <pre> io.use(passportSocketIo.authorize({
|
|||
|
cookieParser:cookieParser,
|
|||
|
key:'express.sid',
|
|||
|
secret:process.env.SESSION_SECRET,
|
|||
|
store:sessionStore
|
|||
|
})); </pre>您还可以选择将“成功”和“失败”与在客户端尝试连接时身份验证过程完成后调用的函数一起传递。现在可以在套接字对象上以<code>socket.request.user</code>访问用户对象。例如,现在您可以添加以下内容: <code>console.log('user ' + socket.request.user.name + ' connected');</code>它将登录已连接的服务器控制台!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/a9e69ff91337500d5171e29324e1ff35">在此处</a>查看项目。 </section>

- text: passportSocketIo是正确需要的

- text: passportSocketIo已正确设置
