Meteor 中服务器端路由的身份验证

问题描述：

为服务器端路由验证用户的最佳方式(最安全和最简单)是什么?

What is the best way (most secure and easiest) to authenticate a user for a server side route?

我使用的是最新的 Iron Router 1.* 和 Meteor 1.*，一开始，我只使用了帐户密码.

I'm using the latest Iron Router 1.* and Meteor 1.* and to begin, I'm just using accounts-password.

我有一个简单的服务器端路由，可以将 pdf 渲染到屏幕上:

I have a simple server side route that renders a pdf to the screen:

both/routes.js

Router.route('/pdf-server', function() {
  var filePath = process.env.PWD + "/server/.files/users/test.pdf";
  console.log(filePath);
  var fs = Npm.require('fs');
  var data = fs.readFileSync(filePath);
  this.response.write(data);
  this.response.end();
}, {where: 'server'});

举个例子，我想做一些接近于建议使用此 SO 答案:

As an example, I'd like to do something close to what this SO answer suggested:

在服务器上:

var Secrets = new Meteor.Collection("secrets"); 

Meteor.methods({
  getSecretKey: function () {
    if (!this.userId)
      // check if the user has privileges
      throw Meteor.Error(403);
    return Secrets.insert({_id: Random.id(), user: this.userId});
  },
});

然后在客户端代码中:

testController.events({
  'click button[name=get-pdf]': function () {
      Meteor.call("getSecretKey", function (error, response) {
        if (error) throw error;

        if (response) 
          Router.go('/pdf-server');
      });
  }
});

但即使我以某种方式使这种方法起作用，除非路由本身以某种方式检查了 Secrets 集合，否则我仍然容易受到用户仅输入/pdf-server"之类的 URL 的影响，对吗?

But even if I somehow got this method working, I'd still be vulnerable to users just putting in a URL like '/pdf-server' unless the route itself somehow checked the Secrets collection right?

在Route中，我可以获取请求，并以某种方式获取头信息?

In the Route, I could get the request, and somehow get the header information?

Router.route('/pdf-server', function() {
  var req = this.request;
  var res = this.response;
}, {where: 'server'});

然后从客户端通过 HTTP 标头传递令牌，然后在路由中检查令牌是否来自集合?

And from the client pass a token over the HTTP header, and then in the route check if the token is good from the Collection?

答

除了使用 url 标记作为其他答案之外，您还可以使用 cookie:

In addition to using url tokens as the other answer you could also use cookies:

添加一些允许您设置 cookie 并在服务器端读取它们的包:

Add in some packages that allow you to set cookies and read them server side:

meteor add mrt:cookies thepumpinglemma:cookies

然后你可以有一些东西将 cookie 与你的登录状态同步

Then you could have something that syncs the cookies up with your login status

客户端

Tracker.autorun(function() {
     //Update the cookie whenever they log in or out
     Cookie.set("meteor_user_id", Meteor.userId());
     Cookie.set("meteor_token", localStorage.getItem("Meteor.loginToken"));
});

服务器端

在服务器端你只需要检查这个cookie是否有效(使用铁路由器)

On the server side you just need to check this cookie is valid (with iron router)

Router.route('/somepath/:fileid', function() {

   //Check the values in the cookies
   var cookies = new Cookies( this.request ),
       userId = cookies.get("meteor_user_id") || "",
       token = cookies.get("meteor_token") || "";

   //Check a valid user with this token exists
   var user = Meteor.users.findOne({
       _id: userId,
       'services.resume.loginTokens.hashedToken' : Accounts._hashLoginToken(token)
   });

   //If they're not logged in tell them
   if(!user) return this.response.end("Not allowed");

   //Theyre logged in!
   this.response.end("You're logged in!");

}, {where:'server'});
