用Poltergeist PhantomJS Capybara驅動程序設置餅乾

Question

我正在運行試圖使用Poltergeist gem設置cookie的問題，並且通過在Poltergeist gem中讀取已關閉的問題，看起來這是我的一個用戶錯誤問題，但我已經花了整整一天的時間嘗試正確設置cookie，而且我似乎無法正確設置。

注意：此測試在硒中正常工作，但由於運行時硒問題，我想使用poltergeist。

我正在使用的應用程序使用「_location」cookie來確定一些總體設置，並且我需要在應用程序中第一次訪問任何頁面時訪問cookie。否則，我會得到一個javascript錯誤，查找由於未設置位置而未設置的值。

The README for the Poltergeist gem顯示了餅乾

操縱餅乾

下面的方法來檢查和處理餅乾以下用法：

page.driver.cookies - 當前頁面訪問餅乾的哈希值。密鑰是cookie名稱。值爲Cookie對象，具有以下方法：name,value, domain, path,secure?,httponly?,expires。

page.driver.set_cookie(name, value, options = {}) - 設置一個cookie。選項散列可以採用以下鍵：:domain,:path,:secure,:httponly,:expires。 :expires應該是一個Time對象。

page.driver.remove_cookie(name) - 刪除一個cookie

- 規格/ spec_helper.rb

Capybara.register_driver :poltergeist do |app| 
    Capybara::Poltergeist::Driver.new(app, :debug => true) 
end 

Capybara.javascript_driver = :poltergeist

有了這次失敗，我想也許我應該訪問該頁面之前設置的cookie，但似乎當我用page.driver.set_cookie命令我用之前「登陸」，在我的水豚腳本，它並沒有設置任何東西。從這個修改的代碼塊和這個結果集可以看出。

我也試圖在phantomjs_options通過阻止對吵鬧鬼司機，與外部的cookies文件。這實際上似乎讓我有點進一步，但我結束了一個空cookie_jar。你可以看到下面這樣的嘗試：

--spec/spec_helper.rb

Capybara.register_driver :poltergeist do |app| 
    Capybara::Poltergeist::Driver.new(app, [phantomjs_options: [--cookies-file="#{::Rails.root}/spec/requests/cookies.txt"]]) 
    end 

    Capybara.javascript_driver = :poltergeist 

- cookie.txt的

phantom.addCookie({ 
    'name':  '_location', 
    'value': 'US', 
    'domain': 'localhost', 
    'expires': (new Date()).getTime() + 3600 
});

Answer 1

我相信你指定選項給Poltergeist的嘗試與PhantomJS的選項混淆。您的註冊塊應該如下所示：

Capybara.register_driver :poltergeist do |app| 
    Capybara::Poltergeist::Driver.new(app, :phantomjs_options => ["--cookies-file=#{::Rails.root}/spec/requests/cookies.txt"]) 
end 

希望有所幫助。
