在Ruby on Rails中使用Google OAuth2 API

Question

我有一個包含多個客戶帳戶的系統，每個帳戶至少有一個擁有Google Analytics帳戶的網站。 我需要我的客戶授權我的系統訪問Google Analytics帳戶，以便我可以生成月度自動報告頁面視圖，並將這些信息與我係統的其他信息一起顯示。我想這樣做，而不需要客戶再次將我的應用程序授權給他們的Google Analytics帳戶。

當客戶端授權訪問Google Analytics時，它會運行約1小時（我相信它是會話時間令牌expires_in: 3600）。在此之後，我無法訪問Google Analytics客戶端。正如你可以在代碼中看到的，我已經嘗試使用access_type:: offline並用client.update_token!更新客戶端令牌，但我不知道如何執行此操作。任何人都可以告訴我，我想要做什麼是可能的，並告訴我如何做到這一點，以便我可以生成月度報告，而無需客戶端再次授權我的應用程序？我在我的控制器中創建了一些方法（我知道代碼不好，這只是一個測試，也許我應該在將訪問令牌寫入我的數據庫之前加密它）。

     client_info = {

Answer 1

這很容易，但我想我是不會把token_credential_uri在調用API在我的測試。

觀察答案「How do I refresh my google_oauth2 access token using my refresh token? 」我找到了正確的方法來做到這一點。

我剛剛在API調用中添加了以下參數：client_id，client_secret，token_credential_uri和refresh_token。

def analytics_report 
    entity_conditions = { entity_type: ContractedProduct.name, entity_id: @contracted_product.id } 
    api_integration_refresh_token = ApiIntegration.find_by entity_conditions.merge(key: ApiIntegration::GOOGLE_ANALYTICS_KEYS[:refresh_token]) 
    api_integration_profile_id = ApiIntegration.find_by entity_conditions.merge(key: ApiIntegration::GOOGLE_ANALYTICS_KEYS[:profile_id]) 

    client_info = { 
      client_id: Rails.configuration.x.google_api['client_id'], 
      client_secret: Rails.configuration.x.google_api['client_secret'], 
      token_credential_uri: Rails.configuration.x.google_api['token_credential_uri'], 
      refresh_token: api_integration_refresh_token.value 
    } 
    client = Signet::OAuth2::Client.new(client_info) 
    service = Google::Apis::AnalyticsV3::AnalyticsService.new 
    service.authorization = client 
    profile_id = 'ga:' + api_integration_profile_id.value 
    start_date = Date.today.at_beginning_of_month.last_month.to_s 
    end_date = Date.today.at_beginning_of_month.last_month.to_s 
    metrics = 'ga:pageviews' 
    dimensions = { 
      dimensions: 'ga:date' 
    } 

    @report = service.get_ga_data(profile_id, start_date, end_date, metrics, dimensions) 
end
