Accounts.onLogin抛出会话未找到错误

Question

LoggedInUser运行良好，但是无论何时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会抛出以下错误。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控制台出错

Answer 1

您正在使用的onLogin函数需要根据以下行的Session包：

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

无法找到控制台状态中的错误，而不是会话包。请确保以下内容：

1. 已安装Meteor Session。如果没有，请安装： meteor add Session

在项目文件夹中的终端中。

2. 会话导入到您要使用它的文件中，如果没有，请在文件顶部添加： import { Session } from 'meteor/session'
