验证码挑战问题
我正在尝试为我的客户配置一个应用程序,我正在使用 recaptcha 进行垃圾邮件控制,并且我正在使用 ruby on Rails (也使用此插件 http://github.com/ambethia/recaptcha/)。
我的客户想要一个简单的挑战,因为他无法阅读,这太难了。有什么办法可以让挑战变得更容易吗?

ReCaptcha 是第三方验证码,我不相信他们可以让您控制他们提供的验证码。
确实,人们对验证码的一大抱怨是它们难以阅读,但如果它们易于阅读,垃圾邮件发送者也很容易通过。你真的赢不了。 :(
与 recapcha 相关的好消息是,通常您只需正确答对两个单词之一即可通过测试,而且通常是更容易阅读的一个。如果您尽最大努力使用另一个单词,验证码通常会让您通过(有关其工作原理以及原因的详细信息,请参阅验证码网站)。
ReCaptcha is a third-party captcha, and I don't believe they give you any control over what captchas they serve.
It is true that a big complaint people have about captchas is that they can be hard to read, but if they were easy to read, they would also be easy for spammers to get past. You really can't win. :(
The good news with recaptcha in particular is that often you only have to get one of the two words right to pass the test, and it's usually the easier-to-read one. If you give your best effort with the other one, recaptcha will often let you through. (see the recaptcha site for details of how it works and why this is the case)
一种解决方案可能是使用一些逻辑问题,而不是混淆验证码图像。有一个插件用于此目的。
One solution might be to use some logic questions instead of confusing captcha images. There is a plugin for this.
