Question

我有一个在server / methods / methods.js中定义的方法：

Meteor.methods({
  'createRole': function(name) {
    if (this.connection && !Roles.userIsInRole(this.userId, 'manage-users')) {
      throw new Meteor.Error('Not authorized to create user roles');
    } else if (!Meteor.roles.find({name: name}).count()) {
      Roles.createRole(name);
      var admins = Meteor.users.find({ emails: { $elemMatch: { address: { $in: _.pluck(Meteor.settings.admins, 'email')}}}}).fetch();
      return Roles.addUsersToRoles(admins, name);
    }
  },

我在server / config / roles.js中调用该方法：

var roles = [
    'manage-users',
    'schedule-any',
    'edit-any',
    'delete-any',
    'manage-settings',
    'schedule-own',
    'edit-own',
    'delete-own'
  ];

// Creates any roles in the list that don't exist
roles.forEach(function(role) {
  if (!Meteor.roles.find({name: role}).count()) {
    Meteor.call('createRole', role);
  }
});

这导致404具有以下堆栈跟踪：

为什么我无法调用此方法？我可以在server / startup / startup.js中调用其他方法，所以我很困惑为什么我不能在这里调用这个特定的方法。

Answer 1

server/config/roles.js在server/methods/methods.js之前进行评估（它们具有相同的嵌套级别，＆＃39; config＆＃39;按字母顺序排列＆＃39;方法＆＃39;），因此，方法在通话时没有定义。一个简单的解决方案就是在Meteor.startup回调中调用该方法：

Meteor.startup(function () {
  roles.forEach(function(role) {
    if (!Meteor.roles.find({name: role}).count()) {
      Meteor.call('createRole', role);
    }
  });
});

这将确保在执行roles代码之前评估所有文件。替代解决方案包括在lib目录中移动方法定义或将其添加到包中。

尝试在Meteor.startup中运行它

Meteor.startup(function () {
    roles.forEach(function(role) {
        if (!Meteor.roles.find({name: role}).count()) {
            Meteor.call('createRole', role);
        }
    });
});

为什么我的Meteor方法404
