我认为将您的Recaptcha私钥放在javascript中是一个漏洞，Recaptcha应该在服务器端代码上进行验证，此问题包含有关如何在Asp.Net MVC中实现Recaptcha的有用链接. stackoverflow.com/questions/4611122/how-to-implement-recaptcha-for-asp-net-mvc>如何为ASP.NET MVC实现reCaptcha?我使用了这种方法，并且效果很好 http://www.dotnetcurry.com/ShowArticle.aspx?ID=611&AspxAutoDetectCookieSupport = 1
