Cucumber：使用Poltergeist（PhantomJS）禁用或删除本地存储

正在尝试为Cucumber测试禁用或删除本地存储

我尝试了以下方法：

page.driver.execute_script("localStorage.clear()")

但是我收到以下错误

 One or more errors were raised in the Javascript code on the page. If you don't care about these errors, you can ignore them by setting js_errors: false in your Poltergeist configuration (see documentation for details).

  SECURITY_ERR: DOM Exception 18: An attempt was made to break through the security policy of the user agent.
  at phantomjs://webpage.evaluate():1
  at phantomjs://webpage.evaluate():1
  at phantomjs://webpage.evaluate():1
  at phantomjs://webpage.evaluate():1 (Capybara::Poltergeist::JavascriptError)

我所做的是：

  visit '<the_url_needed>'
  page.execute_script('if (localStorage && localStorage.clear) localStorage.clear()')

访问“
page.execute_脚本（'if（localStorage&&localStorage.clear）localStorage.clear（）

---

希望有帮助

我也犯了同样的错误。问题是，我试图在不首先访问页面的情况下执行脚本。这会抛出上面Justin解释的错误：

shared_context'@用户已登录'do
在做之前
#访问“/”
凭据=@user.create\u new\u auth\u令牌
令牌=凭证['access-token']
page.execute_脚本“localStorage.setItem（'token'，'#{token}'）”
结束
结束

这项工作：

shared_context'@用户已登录'do
在做之前
访问“/”
凭据=@user.create\u new\u auth\u令牌
令牌=凭证['access-token']
page.execute_脚本“localStorage.setItem（'token'，'#{token}'）”
结束
结束
