Question

LoggedInUser可以正常运行，但只要应用程序启动并且查询URL就像尝试登录或导航到任何其他URL一样，Accounts.onLogin会引发以下错误。我不知道可能是什么原因。

var LoggedInUser = FlowRouter.group({
  name: 'currentUser', triggersEnter: [function () {
    if (!Meteor.loggingIn() || !Meteor.userId()) {
      var currentRoute = FlowRouter.current();
      if (!currentRoute.route.name === 'home') {
        console.log(currentRoute.path);
          Session.set('redirectAfterLogin', currentRoute.path);
      }
      FlowRouter.go('home');
    }
  }]
});

Accounts.onLogin(function () {
  let redirect = Session.get('redirectAfterLogin');
  if (redirect) {
    if (redirect != 'home') {
      FlowRouter.go(redirect);
    }
  }
});

cmd控制台上的错误

您使用的onLogin函数根据以下行需要Session程序包：

  let redirect = Session.get('redirectAfterLogin');

找不到控制台状态中的错误，而不是Session软件包。请确保以下几点：

流星会话已安装。如果没有，请安装：
```
meteor add Session
```

在终端的项目文件夹中。

会话已导入到您要使用的文件中，如果没有，请在文件顶部添加：
```
import { Session } from 'meteor/session'
```

Accounts.onLogin抛出会话未找到错误
