Accounts.onLogin引發未找到會話錯誤

Question

LoggedInUser可以很好地LoggedInUser作用，但是只要應用程序啟動並且查詢URL就像嘗試登錄或導航到其他任何URL， Accounts.onLogin引發以下錯誤。 我不知道是什么原因。

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控制台錯誤

Answer 1

您正在使用的onLogin函數根據以下行需要Session軟件包：

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

找不到控制台狀態錯誤，而不是Session軟件包。 請確保以下幾點：

1. 流星會話已安裝。 如果沒有，請使用以下命令進行安裝：

    meteor add Session 

在終端的項目文件夾中。

2. 會話已導入到您要使用的文件中，如果沒有，請在文件頂部添加：

    import { Session } from 'meteor/session'
