从Meteor.method获取它:
// server
Meteor.methods({
getAccessToken : function() {
try {
return Meteor.user().services.facebook.accessToken;
} catch(e) {
return null;
}
}
});
// client
Meteor.call("getAccessToken", function(error, accessToken){
console.log(accessToken);
})
或发布:
//server
Meteor.publish("currentUserAccessToken", function(){
var self = this;
if (this.userId()){
handle = Meteor.users.find(this.userId()).observe({
added: function(user){
self.set("currentUserAccessToken", user._id, {value: user.services.facebook.accessToken});
self.flush();
},
changed: function(user){
self.set("currentUserAccessToken", user._id, {value: user.services.facebook.accessToken});
self.flush();
}
});
this.onStop(function() {
handle.stop();
});
}
});
//client
var AccessToken = new Meteor.Collection("currentUserAccessToken");
Meteor.subscribe("currentUserAccessToken");
//access the value
var accessToken = AccessToken.findOne().value;

更新和简化Lloyd's answer,我们得到了这个:
Meteor.publish("currentAccessToken", function(){
return Meteor.users.find(this.userId, {fields: {'services.facebook.accessToken': 1}});
});
Meteor.autosubscribe(function(){
var newUser = Meteor.user();
Meteor.subscribe('currentAccessToken');
});
每次用户更改状态时都会更新,并且Meteor.user().services.facebook.accessToken
可以访问访问令牌(如果存在)
