移除自动出版物时，在流星中获取Facebook头像 [英] Getting Facebook Avatar in Meteor when Autopublish is removed

问题描述

目前，当自动发布被移除时，只有{{currentUser.profile.name}}有效。我想尝试从Facebook获得{{currentUser.profile.first_name}}和头像，但无法这样做。这是我的代码...

Currently when auto publish is removed, only {{currentUser.profile.name}} works.I'm trying to get {{currentUser.profile.first_name}} and the avatar from Facebook but have not been able to do so. Here is my code...

在服务器端：

 Meteor.publish('userData', function() {
        if(!this.userId) return null;
        return Meteor.users.find(this.userId, {fields: {
            'services.facebook': 1
        }});
    });

铁路由器：

Router.configure({
    waitOn: function() {
        return Meteor.subscribe('userData');
    }   
 });

从我的理解，我看到Meteor发布了所有的userData，然后通过铁路路由器订阅。我不明白为什么这不行 - 我认为{{currentUser.profile.first_name}}应该工作，但不是。

From my understanding, I see that Meteor is publishing all the userData and then subscribing to it via Iron Router. What I don't understand is why this is not working -- as I think {{currentUser.profile.first_name}} should work but isn't.

推荐答案

像Richard所说，创建用户时，您可以将服务文档复制到配置文件。

Like Richard suggests, when a user is created, you can copy the services document to the profile doc.

Accounts.onCreateUser(function(options, user) {
    // We still want the default hook's 'profile' behavior.
    if (options.profile) {
        user.profile = options.profile;
        user.profile.memberSince = new Date();

        // Copy data from Facebook to user object
        user.profile.facebookId = user.services.facebook.id;
        user.profile.firstName = user.services.facebook.first_name;
        user.profile.email = user.services.facebook.email;
        user.profile.link = user.services.facebook.link;
    }

    return user;
});

您的出版物获得他们的名字和Facebook ID将如下所示...

Your publication to get their first name and Facebook ID would look like this...

/* ============== Single User Data =============== */
Meteor.publish('singleUser', function(id) {
    check(id, String);

    return Meteor.users.find(id,
        {fields: {'profile.facebookId': 1, 'profile.name': 1, 'profile.firstName': 1, 'profile.link': 1}});
});

您可以使用模板助手功能访问用户的Facebook头像...

You can access a user's Facebook avatar with a template helper function...

Template.profileView.helpers({
    userPicHelper: function() {
        if (this.profile) {
            var id = this.profile.facebookId;
            var img = 'http://graph.facebook.com/' + id + '/picture?type=square&height=160&width=160';
            return img;
        }
    }
});

在您的模板中，您可以使用以下帮助器（前提是您将其包装在块中包含用户数据）：

In your template, you can then use the following helper (provided you are wrapping this in a block that contains user data):

<img src="{{userPicHelper}}" alt="" />
