ruby-on-rails - 使用 Steam OmniAuth gem 连接 Steam 的 OpenId 会出现 "invalid_credentials"错误

Question

我正在尝试使用 omniauth-steam gem 通过 Steam 连接用户并检索用户的 ID64。我正在使用本地网络上的服务器运行 Ruby on Rails 5.0.1，该服务器运行 Apache 和Passenger。每当我尝试连接到/auth/steam 时，我都会通过“连接”按钮重定向到 Steam 网页(我已经登录)。当我单击该按钮时，我会收到一个错误页面，其中包含“invalid_credentials”消息。我已登录 Steam，可以毫无问题地浏览该站点。这条消息从何而来？我怎样才能解决这个问题？到目前为止，这是我的代码。

Omniauth 初始化器 :

# config/initializers/omniauth.rb
Rails.application.config.middleware.use OmniAuth::Builder do
  provider :steam, Rails.application.secrets.steam_web_api_key
end

Controller :

skip_before_filter :verify_authenticity_token, :only => :auth_callback

def index
end

def auth_callback
    auth = request.env['omniauth.auth']
    session[:current_user] = {
        :nickname => auth.info['nickname'],
        :image => auth.info['image'],
        :uid => auth.uid
    }
    redirect_to root_url
end

查看 :

<p><%= link_to image_tag("http://cdn.steamcommunity.com/public/images/signinthroughsteam/sits_large_noborder.png"), '/auth/steam' %></p>

路线 :

get 'admin/index'
post 'auth/steam/callback' => 'admin#auth_callback'

root 'admin#index'

Answer 1

事实证明，在这种情况下，这是因为运行脚本的服务器与 Steam 的服务器之间存在时差。我的服务器上的日期/时间有几分钟的时间，一旦我纠正了时间差异，错误消息就消失了，登录过程成功了。
