我在 asp.net 中有一个使用 jQuery 向导的在线表单,我不确定我的最后一个阶段是否需要验证码控件来防止机器人/爬虫。
那么我需要一个验证码吗?为我的在线网络表单...??有推荐吗??

Captcha is recommended if your application/form is being attacked by bots. If you feel, there are attacks and you have sensitive information, you can opt for captcha (or recaptcha).
If you are not going to make it public, i.e. providing form to invited users only, then, you probably don't need Captcha. But, if it is going to be open to public,(like gmail for example) then, its definitely recommended to put captcha in the form.
