Ruby on rails Rails Poltergeist/PhantomJS未呈现www.example.com 背景

下面是

test/integration/projects\u test.rb

。我们要求登录用户访问

项目\u url

setup do
  ...
  login_as @user
  ...
end

# PARTIAL SUCCESS (RENDERS LOGIN PAGE (instead of projects), IGNORES LOGGED IN @USER)
test "can visit projects" do
  visit "http://127.0.0.1:3000/projects"
  page.save_screenshot
end

# FAILURE (BLANK PAGE)
test "can visit projects_url" do
  visit projects_url
  page.save_screenshot
end

当我激活调试消息时，它会显示发生了什么：

login\u as@user

正在登录www.example.com

访问”http://127.0.0.1:3000/projects“

呈现一个页面，但它不会进入

www.example.com

，因此我们的

@user

不会被识别为已登录

visit projects\u url

将进入

www.example.com/projects

，Poltergeist/PhantomJS将其呈现为空白

问题: 那么，我该如何：

• 让Poltergeist/PhantomJS在

  www.example.com

  上呈现页面
• 将所有内容移到127.0.0.1:3000

请求 将Poltergeist设置为

url\u白名单：['127.0.0.1'，'localhost'，'example.com']

使用

访问根路径运行测试

结果:

如果您希望允许页面请求访问该url，则需要在Poltergeist白名单中允许“”

此外，
http://127.0.0.1:3000
很可能是您的开发实例，因此您不希望测试命中它，因为它不会使用您设置的测试数据。
我尝试过这样做（将
url\u whitelist
to'），现在我从项目中得到了胡言乱语。看起来像是'¾ïWïri]÷S×V@1kÜÕZ'$6÷qÛ½ååí@+Ž381; lžI“üsPzUeèäñ‡B”。@sscirrus查看您的test.log，查看发出了什么请求以及响应呈现了什么，我还假设您将
url\u白名单设置为一个包含“example.com”的数组，而不仅仅是我仍在调查的“example.com”，而是test.log中的一些查询以
回滚
（我的本地服务器处理得很好）。我尝试使用
root\u path
和
root\u url
-
root\u url
将我带到example.com而不是我的root。
root\u path
为空。对于第二个问题，我确认我正在使用数组作为
url\u白名单
。设置你的poltergeist
url\u白名单=['127.0.0.1'、'localhost'、'example.com']
然后尝试使用'root\u path
/
projects\u path`而不是xxx\u url运行-如果不起作用，请将test.log添加到问题中。另外，您是否确定您的测试实际上使用的是poltergeist，而不仅仅是使用rack\u测试驱动程序（完全忽略域），并且
www.example.com
是否在您的机器上解析为
127.0.0.1
？我刚刚添加了该测试的结果。
