ASP.Net MVC Recaptcha Jquery Ajax問題

Question

我正在使用ASP.Net MVC並嘗試將Google reCaptcha對象實現爲頁面。

我想避免在我的表單中使用模型，並且只想直接調用使用jquery ajax的方法。

我有驗證碼出現，但是在調試器中檢查RecaptchaVerificationHelper對象時，輸入的任何內容都顯示爲空。

任何建議，以保持它像我擁有它輕量級，但保持它的工作。

注意：大多數邏輯已被剝離出來，只是試圖讓驗證碼邏輯工作。

CSHTML樣品：

@using Recaptcha.Web.Mvc; 

<script type="text/javascript"> 
function createUser() { 

      $.ajax({ 
       type: "POST", 
       url: 'CreateUser', 
       contentType: "application/json; charset=utf-8", 
       success: function (response) { 
        if (response.Success == true) { 
         alert("success"); 
         //redirectSuccess(); 
        } else { 
         alert("failed"); 
        } 
       }, 
       error: function (err) { 
        commonError(err); 
       } 
      }); 

    } 
</script> 

@Html.Recaptcha(publicKey: "6LdxcPgSAA...", theme: Recaptcha.Web.RecaptchaTheme.Clean); 
<br /> 
<input type="button" value="Submit" onclick="createUser();" style="margin-right:300px;" /> 

CS服務器代碼示例：

public ActionResult User() 
     { 
      return View(); 
     } 

public JsonResult CreateUser() 
     { 
      Wrapper.ValidationResponse response = new Wrapper.ValidationResponse(); 
      response.Success = true; 

      RecaptchaVerificationHelper recaptchaHelper = this.GetRecaptchaVerificationHelper(); 

      if (String.IsNullOrEmpty(recaptchaHelper.Response)) 
      { 

       response.Success = false; 
      } 

      RecaptchaVerificationResult recaptchaResult = recaptchaHelper.VerifyRecaptchaResponse(); 

      if (recaptchaResult != RecaptchaVerificationResult.Success) 
      { 
       response.Success = false; 
      } 

       try 
       { 
        //removed logic 
        return Json(response); 
       } 
       catch (Exception ex) 
       { 
        response.Success = false; 
        response.Message = "Failed to create new user. Please contact us if the issue persists."; 
        return Json(response); 
       } 
     } 

由於事先

經過一週的生氣，我終於找到了一個直接使用開發者API的工作解決方案。

我所做的是使用jsAPI，並使用API​​手動添加驗證碼控件到頁面。提交時，我捕獲了recaptcha響應並將其發送給服務器端。

從服務器端，我然後驗證請求遵循API說明和使用本教程在這裏找到：http://www.codeproject.com/Tips/851004/How-to-Validate-Recaptcha-V-Server-side 然後我發送請求並相應地處理響應。

HTML：

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

<script type="text/javascript"> 
    var captcharesponse = grecaptcha.getResponse(); 


      $.ajax({ 
       type: "POST", 
       url: 'CreateUser', 

       data: "{captcharesponse:" + JSON.stringify(captcharesponse) + "}", 
       contentType: "application/json; charset=utf-8", 
       success: function (response) { 

        if (response.Success == true) { 
         alert("success"); 

        } else { 
         alert("failed"); 

        } 

       }, 
       error: function (err) { 
        commonError(err); 
       } 
      }); 
     } 
</script> 

<div class="g-recaptcha" 
       data-sitekey="[public key here]"></div> 
      <br /> 
<input type="button" value="Submit" onclick="createUser();" style="margin-right:300px;" />

你的控制器方法

public JsonResult CreateUser() //<-- CamelCase 

不AJAX調用匹配

url: 'createUser', //<-- small case
