Rails 中可能出现 HTTP 基本自定义错误吗？

发布于 2024-12-07 13:05:17 字数 650 浏览 0 评论 0原文

我正在使用 Ruby 1.8.7 在 Rails 2.3.14 中构建一个应用程序。

我的客户请求在网络研讨会页面上进行非常简单的身份验证。我认为使用 http_auth 非常合适，因为它只需要一个非常基本的用户名和密码。

现在，她要求如果他们点击取消或使用错误的信息，他们会被重定向到一个页面，该页面基本上显示“如果您忘记登录信息，请联系我们”。

我该如何做到这一点，以便当我们收到“HTTP Basic：访问被拒绝”时。错误，我可以重定向到页面吗？或者，只需使用我们的自定义样式/内容自定义此页面？

提前致谢。

这是我的网络研讨会控制器的代码：

class WebinarsController < ApplicationController
before_filter :authenticate, :only => [:bpr]

def bpr
 render :action => :bpr
end

protected 
def authenticate
  authenticate_or_request_with_http_basic do |username, password|
    username == "abc" && password == "123"
  end
end

end

I am building an application in Rails 2.3.14 using Ruby 1.8.7.

My client has requested a very simple authentication on a webinars page.
I thought using http_auth would be very fitting, as it just needs a very basic username and password.

Now, she has requested that if they hit cancel or use the wrong information, they get redirected to a page that basically says "if you forget login information, contact us."

How do I make it so that when we get the "HTTP Basic: Access denied." error, I can instead redirect to a page? Or, instead, just customize this page with our custom styles/content?

Thanks in advance.

Here is the code from my webinars controller:

class WebinarsController < ApplicationController
before_filter :authenticate, :only => [:bpr]

def bpr
 render :action => :bpr
end

protected 
def authenticate
  authenticate_or_request_with_http_basic do |username, password|
    username == "abc" && password == "123"
  end
end

end

如果您查看 authenticate_or_request_with_http_basic 源，您会看到以下内容：

def authenticate_or_request_with_http_basic(realm = "Application", &login_procedure)
  authenticate_with_http_basic(&login_procedure) || request_http_basic_authentication(realm)
end

def authenticate_with_http_basic(&login_procedure)
  HttpAuthentication::Basic.authenticate(request, &login_procedure)
end

#...

def authenticate(request, &login_procedure)
  unless request.authorization.blank?
    login_procedure.call(*user_name_and_password(request))
  end
end

因此您的 login_procedure 块只要返回 true 就可以执行几乎任何操作成功登录。特别是，它可以调用redirect_to：

def authenticate
  authenticate_or_request_with_http_basic do |username, password|
    if(username == "abc" && password == "123")
      true
    else
      redirect_to '/somewhere/else/with/instructions'
    end
  end
end

If you look at the authenticate_or_request_with_http_basic source, you'll see this:

def authenticate_or_request_with_http_basic(realm = "Application", &login_procedure)
  authenticate_with_http_basic(&login_procedure) || request_http_basic_authentication(realm)
end

def authenticate_with_http_basic(&login_procedure)
  HttpAuthentication::Basic.authenticate(request, &login_procedure)
end

#...

def authenticate(request, &login_procedure)
  unless request.authorization.blank?
    login_procedure.call(*user_name_and_password(request))
  end
end

So your login_procedure block can do pretty much anything it wants as long as it returns true for a successful login. In particular, it can call redirect_to:

def authenticate
  authenticate_or_request_with_http_basic do |username, password|
    if(username == "abc" && password == "123")
      true
    else
      redirect_to '/somewhere/else/with/instructions'
    end
  end
end
