Question

我已安装Meteor http://php.net/manual/en/functions.user-defined.php软件包和Facebook软件包，以允许用户连接其Facebook帐户。

我在OAuth中找到了一些代码。我已经实现了一个客户端处理程序来启动授权流程

'click #facebook-connect': function(e) {
  var service;

  service = "facebook";

  Facebook.requestCredential({
    requestPermissions: ["email"]}, function(token) {
    var secret;
    secret = OAuth._retrieveCredentialSecret(token);
    return Meteor.call("userAddOAuthCredentials", token, service, secret, function(err, resp) {
      if (err != null) {
        return Meteor.userError.throwError(err.reason);
      }
    });
  });
},

以及将Facebook令牌添加到数据库的服务器端方法，该方法由客户端按钮单击调用。

Meteor.methods({
'userAddOAuthCredentials':  function(token, service, secret) {
  var data, oldUser, ref, serviceSearch, services;
  services = Meteor.user().services;
  serviceSearch = {};
  data = {};
  switch (service) {
    case "facebook":
      if (services.facebook == null) {
        data = (ref = Facebook.retrieveCredential(token, secret)) != null ? ref.serviceData : void 0;
        services.facebook = data;
        serviceSearch = {
          "services.facebook.id": services.facebook.id
        };
      } else {
        throw new Meteor.Error(500, "You already have a linked Facebook account with email " + services.facebook.email + "...");
      }
  }
  oldUser = Meteor.users.findOne(serviceSearch);
  if (oldUser != null) {
    throw new Meteor.Error(500, "Your " + service + " account has already been assigned to another user.");
  }
  Meteor.users.update(this.userId, {
    $set: {
      services: services
    }
  });
  if (data.email != null) {
    if (!_.contains(Meteor.user().emails, data.email)) {
      return Meteor.users.update(this.userId, {
        $push: {
          "emails": {
            address: data.email,
            verified: true
          }
        }
      });
    }
  }
}
});

运行时我得到这个堆栈跟踪：

客户端代码永远不会得到服务器端方法的秘密。为什么会发生这种情况，如何获得正确的客户端密钥以传递给我的服务器方法？
