Rails 4 - 设计 Omniauth 并允许单个用户使用多种社交媒体策略进行身份验证
Rails 4 - Devise Omniauth and allowing a single user to authenticate with multiple social media strategies
我正在尝试用 Rails 4.
制作一个应用
我（3 年多来）一直在尝试弄清楚如何让 Devise 和 Omniauth 发挥作用，以便用户可以将多个社交媒体帐户添加到他们的用户个人资料中。
我已经阅读了所有设计和 omniauth 文档。对于这些文档，我最多只能添加 1 个社交媒体帐户。那不是我想要的。

None 的作品。我不知道如何插入它。我不确定我是否应该将存储在我的身份 table 中的属性包含在控制器的允许参数中？？
属性是：
t.integer "user_id"
t.string "provider"
t.string "accesstoken"
t.string "refreshtoken"
t.string "uid"
t.string "name"
t.string "email"
t.string "nickname"
t.string "image"
t.string "phone"
t.string "urls"
我已经完成了这项工作，因此用户只能使用一种方法进行身份验证。我不知道如何让它工作。我已经尝试了我能找到的所有资源来解决这个问题，但我被卡住了。
我有这一切与每个单独的社交插件和电子邮件一起工作，但我没有为现有用户（在当前会话中）添加身份的能力，以便他们下次登录时可以使用任何 acceptable 身份。
有人能帮忙吗？
由于无法查看您的所有代码，我只是创建了一个 shell 应用程序，该应用程序 运行 与多个提供商合作。我只是按照您在 sourcey. Here is the link to my repo 中提到的教程中的步骤进行操作。
您应该能够通过在 devise.rb 初始值设定项中输入来自 facebook、twitter 和 linkedin 的应用程序密钥和秘密令牌来克隆它和 运行 它。为了让它在本地工作，你需要确保 twitter 上的回调 url 设置为 http://127.0.0.1:3000/.
如果您想为用户提供添加他们自己的 omniauth 帐户（身份）的选项，而不是通过应用授权自动完成，您可以只为用户制作一个表单，让其输入数字 uid 并创建身份你自己在控制器或后端是这样的：
new_identity = Identity.new
new_identity.user_id = "current user's id"
new_identity.provider = "facebook"
new_identity.uid = "0123456789"
new_identity.save!
用户必须从站点获取他们的数字 uid 并自行输入。
我正在尝试用 Rails 4.
制作一个应用我（3 年多来）一直在尝试弄清楚如何让 Devise 和 Omniauth 发挥作用，以便用户可以将多个社交媒体帐户添加到他们的用户个人资料中。
我已经阅读了所有设计和 omniauth 文档。对于这些文档，我最多只能添加 1 个社交媒体帐户。那不是我想要的。

None 的作品。我不知道如何插入它。我不确定我是否应该将存储在我的身份 table 中的属性包含在控制器的允许参数中？？
属性是：
t.integer "user_id"
t.string "provider"
t.string "accesstoken"
t.string "refreshtoken"
t.string "uid"
t.string "name"
t.string "email"
t.string "nickname"
t.string "image"
t.string "phone"
t.string "urls"
我已经完成了这项工作，因此用户只能使用一种方法进行身份验证。我不知道如何让它工作。我已经尝试了我能找到的所有资源来解决这个问题，但我被卡住了。
我有这一切与每个单独的社交插件和电子邮件一起工作，但我没有为现有用户（在当前会话中）添加身份的能力，以便他们下次登录时可以使用任何 acceptable 身份。
有人能帮忙吗？
由于无法查看您的所有代码，我只是创建了一个 shell 应用程序，该应用程序 运行 与多个提供商合作。我只是按照您在 sourcey. Here is the link to my repo 中提到的教程中的步骤进行操作。
您应该能够通过在 devise.rb 初始值设定项中输入来自 facebook、twitter 和 linkedin 的应用程序密钥和秘密令牌来克隆它和 运行 它。为了让它在本地工作，你需要确保 twitter 上的回调 url 设置为 http://127.0.0.1:3000/.
如果您想为用户提供添加他们自己的 omniauth 帐户（身份）的选项，而不是通过应用授权自动完成，您可以只为用户制作一个表单，让其输入数字 uid 并创建身份你自己在控制器或后端是这样的：
new_identity = Identity.new
new_identity.user_id = "current user's id"
new_identity.provider = "facebook"
new_identity.uid = "0123456789"
new_identity.save!
用户必须从站点获取他们的数字 uid 并自行输入。
