如果recaptcha有效,如何启用按钮

captcha recaptcha asp.net-mvc-5 button asp.net

我叫控制器 AccountController 使用recaptcha和如下代码:

[HttpPost]
        public ActionResult FormSubmit()
        {

            var response = Request["g-recaptcha-response"];
            string secretKey = "6Lf_NnQUAAA......";  //Added my secret key that genereted on my re-captcha
            var client = new WebClient();
            var result = client.DownloadString(string.Format("https://google.com/recaptcha/api/siteverify?secret={0}&response{1}", secretKey, response));
            var obj = JObject.Parse(result);
            var status = (bool)obj.SelectToken("success");
            ViewBag.Message = status ? "successs" : "failed";

            return View();
        }

还有,我有 LogIn.cshtml 使用以下代码查看:

<div>
    @using (Html.BeginForm("FormSubmit", "Home", FormMethod.Post))
    {
        <div class="g-recaptcha" data-sitekey="6Lf_NnQUAAA..."></div> //ADDED MY SITE KEY
        <input type="submit" name="commit" value="Join IoT Lab!">  
    }
</div>
<span style="display:inline-block; font-size:20px;margin:20px 0;padding:20px;border:1px solid #D3D3D3">
    @ViewBag.Message
</span>
<p>
    By clicking "Join IoT Lab", you agree to our <br />
    <a href="@Url.Action("PrivacyRulesAndGuidelines", "IOTLabProject")">Terms and conditions</a> and <a href="@Url.Action("PrivacyRulesAndGuidelines", "IOTLabProject")">Privacy policy</a>
</p>

<script src='https://www.google.com/recaptcha/api.js' type="text/javascript"></script>

目前,验证码使用图像进行验证,所以如果我检查正确的图像,验证码将有效,但如果我只是单击提交(“加入物联网实验室”)而不使用验证码,它仍然会重定向我…

那么,如何启用 Join IoT Lab! (commit)按钮在验证recaptcha之后?我是说,如何将recaptcha设置为必需字段?

我想我应该用像 ViewBag 但是怎么办呢?

您可以查看viewbag.message条件“加入物联网实验室!”按钮。此消息表单提交后启用。可能我理解您的问题并给出正确的解决方案。如果您有任何问题,请了解我。

<div>
@using (Html.BeginForm("FormSubmit", "Home", FormMethod.Post))
{
    <div class="g-recaptcha" data-sitekey="6Lf_NnQUAAA..."></div> //ADDED MY SITE KEY
    <input type="submit" name="commit" value="Join IoT Lab!">  
}
</div>
<span style="display:inline-block; font-size:20px;margin:20px 
0;padding:20px;border:1px solid #D3D3D3">
@ViewBag.Message
</span>
<p>
@if(ViewBag.Message=="successs")
{
  By clicking "Join IoT Lab", you agree to our <br />
  <a href="@Url.Action("PrivacyRulesAndGuidelines", "IOTLabProject")">Terms and 
   conditions</a> and <a href="@Url.Action("PrivacyRulesAndGuidelines", 
   "IOTLabProject")">Privacy policy</a>
}
