查找或匹配用户联系人与 Facebook 好友的最佳方式？

我有一个用户，该用户有很多联系人（一些联系人有“姓名”，所有联系人都有“电子邮件”）。联系人有一个 image_url 字段，我想显示该联系人的图片。我想从 Facebook 上提取这些照片。

假设 User.first 的电子邮件地址为“[email protected]”，已注册与脸书。

用户有_许多联系人&&联系人属于用户。

User.first.contacts 
#<Contact id: 1, ctct_name: "Stacy Blah", ctct_email: "[email protected]", user_id: 1, img_url: nil>, 
#<Contact id: 2, ctct_name: nil, ctct_email: "[email protected]", user_id: 1, img_url: nil>, 
#<Contact id: 3, ctct_name: "John Doe", ctct_email: "[email protected]", user_id: 1, img_url: nil>

我的网站上有 fb_graph （使用 Devise :omniauthable）。

当 User.first 连接到 Facebook 时，我可以访问他们的 fb 令牌。所以我可以这样做：

facebook_user = FbGraph::User.new('me', :access_token => access_token).fetch
user_friends = facebook_user.friends

现在查找或匹配 User.first.contacts 与 user_friends 的最佳方法是什么？ 理想情况下，我只需在 Facebook connect 中搜索电子邮件，如下所示：

email = Contact.first.ctct_email
search = FbGraph::User.search(email, :access_token => access_token = user['credentials']['token']) 
Contact.first.img_url = search[0].picture # or something like this

但是 Facebook API 不会公开 user_friends 电子邮件！那么，我能做什么呢？

我一直在尝试根据名称进行匹配，但遇到两个问题：（1）contacts.name 可能为零，（2）user_friends.select {|f| f.name.include?("John Doe")} 限制性太强，名称不完全匹配（例如，contact.name = "John Doe"，但 Facebook 将此人称为“John X. Doe”）。

我还尝试使用名称参数 = User.first.contacts[2].name 搜索 FBGraph::User.search。

search = FbGraph::User.search("John Doe", :access_token => access_token = user['credentials']['token'])

但随后我遇到了一个严重的歧义问题——搜索“John Doe”会出现数千个 Facebook 用户，而且他们不仅限于 user_friends！

这当然是可能的。我见过一些服务可以从 Facebook 中提取给定联系人的图像，其中的信息只有电子邮件那么少。

感谢您的帮助！！

原文

I have a User, and that User has a bunch of contacts (some contacts have "name" and all have "email"). Contacts have a field for an image_url, and I want to show a picture for that contact. I want to pull those pictures from Facebook.

Suppose User.first has email "[email protected]", which is registered with Facebook.

User has_many contacts && Contacts belongs_to User.

User.first.contacts 
#<Contact id: 1, ctct_name: "Stacy Blah", ctct_email: "[email protected]", user_id: 1, img_url: nil>, 
#<Contact id: 2, ctct_name: nil, ctct_email: "[email protected]", user_id: 1, img_url: nil>, 
#<Contact id: 3, ctct_name: "John Doe", ctct_email: "[email protected]", user_id: 1, img_url: nil>

I have fb_graph working on my site (using Devise :omniauthable).

When User.first connects to Facebook, I have access to their fb token. So I can do this:

facebook_user = FbGraph::User.new('me', :access_token => access_token).fetch
user_friends = facebook_user.friends

Now what is the best way to find or match User.first.contacts to user_friends? Ideally, I would simply search Facebook connect for emails, like this:

email = Contact.first.ctct_email
search = FbGraph::User.search(email, :access_token => access_token = user['credentials']['token']) 
Contact.first.img_url = search[0].picture # or something like this

BUT Facebook API doesn't expose user_friends emails! So, what can I do?

I've been trying to match based on names, but I run into two problems: (1) contacts.name may be nil, and (2) user_friends.select {|f| f.name.include?("John Doe")} is too restrictive where the names don't match exactly (e.g., contact.name = "John Doe" but Facebook has this person as "John X. Doe").

I have also tried searching FBGraph::User.search with name parameter = User.first.contacts[2].name.

search = FbGraph::User.search("John Doe", :access_token => access_token = user['credentials']['token'])

But then I have a severe disambiguation problem -- searching "John Doe" brings up thousands of Facebook users, and they aren't limited to the user_friends!

Surely this is possible. I've seen services that can pull an image from Facebook for a given contact, with as little information as an email.

Thank you for your help!!
