Ruby on rails 水豚/Poltergeist-资源请求错误：QNetworkReply:：NetworkError

我正在尝试访问Instagram的位置页面：

https://www.instagram.com/explore/locations/213385402/london-united-kingdom/

虽然Capybara在其他页面（如个人帖子或个人资料）上取得了成功，但当涉及到任何位置页面时，我会得到

内容操作NotPermittedError

我试着调试，但我用尽了所有的选择

我错过了什么

编辑：这在开发方面很好，在Heroku上运行它会带来这个问题

显然Instagram禁止了Heroku。您应该使用代理从Heroku转到Instagram。如何配置Capybara以使用此问题中回答的代理-

您可以在exmaple的任何代理列表中找到代理-

嘿，Dmitry，我不认为这是因为1）我仍然可以刮其他页面，2）他们会在还给我资产和其他东西之前删除我。这是一个快速跳转到conclusion@TheMiniJohn我试着从Heroku那里得到这个页面，有代理也没有。没有代理，Instagram说403禁止。用代理它说200和返回页面。我不知道为什么它只阻止这个页面，但代理解决了这个问题。或者你可以试着更换主机。哦，好的。我会试试看，然后告诉你。
