让captcha插件与register操作一起工作

Question

我让登录部分工作，注册页面清楚地显示captcha，RecaptchaMVC5的.dll表示AccountController不包含verifyReCAPTCHA的定义，但它与登录部分一起工作：

示例：

正在工作的登录名：

 [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public async Task<ActionResult> Login(LoginViewModel model, string returnUrl)
    {
        if (ModelState.IsValid)
        {
            // Verify the recaptcha response.
            ReCaptchaResponse response = await this.verifyReCAPTCHA(model, "key", true);
            if (response.Success)
            {
                var user = await UserManager.FindAsync(model.UserName, model.Password);
                if (user != null)
                {
                    await SignInAsync(user, model.RememberMe);
                    return RedirectToLocal(returnUrl);
                }
                else
                {
                    ModelState.AddModelError("", "Invalid username or password.");
                }
            }
            else
            {
                ModelState.AddModelError("", "Invalid Captcha Code!");
            }
        }
        // If we got this far, something failed, redisplay form
        return View(model);
    }

我的注册模型在verifyReCAPTCHA:上抛出错误

       [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public async Task<ActionResult> Register(RegisterViewModel model)
    {
        if (ModelState.IsValid)
        {
            //Verify the recaptcha response.
            ReCaptchaResponse response = await this.verifyReCAPTCHA(model, "key", true);
            if (response.Success)
            {
                var user = new ApplicationUser() { UserName = model.UserName };
                var result = await UserManager.CreateAsync(user, model.Password);
                if (result.Succeeded)
                {
                    await SignInAsync(user, isPersistent: false);
                    return RedirectToAction("Index", "Home");
                }
                else
                {
                    AddErrors(result);
                }
            }
        }
        // If we got this far, something failed, redisplay form
        return View(model);
    }

我得到的错误

错误1"ReCaptchaMVC5Test.Controllers.AccountController"不包含"verifyReCAPTCHA"的定义

Answer 1

内部模型文件夹>AccountViewModels.cs有

public class LoginViewModel : ReCaptchaViewModel

和

public class RegisterViewModel : <Place 'RecaptchaViewModel' Here>

这就是如何将Captcha的视图模型分配给其他模型

Answer 2

假设这两个方法都在AccountController上，那么verifyReCAPTCHA的方法签名是什么，因为这两个发送不同模型的方法（LoginViewModel和RegisterViewModel）都继承自正确的基？

Answer 3

从我从源代码中可以看出，有一个扩展方法您无法访问。看来您需要将using ReCaptcha.Mvc5;添加到Controller源文件的顶部才能获得访问权限。

verifyReCAPTCHA(this Controller, ReCaptchaViewModel, String, Boolean)

此外，请确保您的model继承自ReCaptcha.Mvc5.Model.ReCaptchaViewModel（如他们的文档所示），这样您就满足了方法签名。
