Question

尝试使用rack-ssl-enforcer时出现参数错误。错误来自初始化！在environment.rb中调用。

我使用的是https://github.com/pelle/rack-ssl-enforcer

版本

在application.rb中：

module MyApp
  class Application < Rails::Application

    config.middleware.use Rack::SslEnforcer, :except => ["/login", "/logout", /^\/static\//, "/"]
  end
end

堆栈跟踪如下：

Answer 1

这是因为你的正则表达式没有包含在%r{}

中

Answer 2

我唯一能想到的是它没有正确评估为没有parens的函数调用。尝试：

module MyApp
  class Application < Rails::Application

    config.middleware.use(Rack::SslEnforcer, :except => ["/login", "/logout", /^\/static\//, "/"])
  end
end

似乎是一个长镜头。语法看起来有效，并且遵循SslEnforced README中的示例，无法想象为什么它会给你这个错误，而不是挑剔parens并以某种方式误解选项hash。

使用Rack :: SslEnforcer初始化时的ArgumentError
