如何根据 ASP.NET Core Razor 页面中的单选按钮选择有条件地重定向到页面？

Question

我是 ASP.NET Core Razor Pages 的新手。我使用 Visual Studio 2010 和 ASP.NET 核心应用程序

的模板构建了一个简单的解决方案

我在登录页面添加了一个包含两个选项的单选按钮，用于选择性别。我想根据单选按钮中的所选选项有条件地 return RedirectionToPage。

如果用户选择男孩 + 添加密码和电子邮件 --> 重定向到“./boysNames”页面

如果用户选择女孩 + 添加密码和电子邮件 --> 重定向到“./girlsNames”页面

这是我的代码：

登录页面中的单选按钮

   <div class="form-group ">
                    <div class="form-check form-check-inline">
                        <input class="form-check-input" type="radio" name="inlineRadioOptions" id="inlineRadio1" value="option1" checked>
                        <label class="form-check-label" for="inlineRadio1">Boy</label>
                    </div>
                    <div class="form-check form-check-inline">
                        <input class="form-check-input" type="radio" name="inlineRadioOptions" id="inlineRadio2" value="option2">
                        <label class="form-check-label" for="inlineRadio2">Girl</label>
                    </div>
                </div>

你可以尝试在Pagemodel中获取radio button的value，如果value是option1，return RedirectToPage("./boysNames");，如果value是option2，return RedirectToPage("./girlsNames");。这是一个演示：

查看：

    <form method="post">
        <div class="form-group ">
            <div class="form-check form-check-inline">
                <input class="form-check-input" type="radio" name="inlineRadioOptions" id="inlineRadio1" value="option1" checked>
                <label class="form-check-label" for="inlineRadio1">Boy</label>
            </div>
            <div class="form-check form-check-inline">
                <input class="form-check-input" type="radio" name="inlineRadioOptions" id="inlineRadio2" value="option2">
                <label class="form-check-label" for="inlineRadio2">Girl</label>
            </div>
        </div>
       
           ...

        <input type="submit" value="submit"/>
    </form>

pagemodel(radio button的值会绑定到inlineRadioOptions):

[BindProperty]
    public string inlineRadioOptions { get; set; }
public async Task<IActionResult> OnPostAsync(string returnUrl = null)
        {
            returnUrl ??= Url.Content("~/");

            ExternalLogins = (await _signInManager.GetExternalAuthenticationSchemesAsync()).ToList();
        
            if (ModelState.IsValid)
            {
                // This doesn't count login failures towards account lockout
                // To enable password failures to trigger account lockout, set lockoutOnFailure: true  lockoutOnFailure: false
                var result = await _signInManager.PasswordSignInAsync(Input.Correo, Input.Contraseña, Input.RememberMe, lockoutOnFailure: false); //I Think I have to add here the radio selection
                if (result.Succeeded)
                {
                    if (inlineRadioOptions == "option1")
                    {
                         _logger.LogInformation("BoysSelection.");
                         return RedirectToPage("./boysNames");
                    }
                    else {
                          _logger.LogInformation("Girls Selection.");
                          return RedirectToPage("./girlsNames");
                   
                    }
                }
            }

            // If we got this far, something failed, redisplay form
            return Page();
        }
