禁用JavaScript时，FluentValidation无法处理表单提交

Question

我使用FluentValidation来验证模型。我已将其设置如下：

模型

public class UserViewModel {
    public String Email { get; set; }
    public String PhoneNumber { get; set; }
    public String FullName { get; set; }
    public String CompanyName { get; set; }
}

验证类

public class UserViewModelValidation: AbstractValidator<UserViewModel> {
    public UserViewModelValidation() {
        RuleFor(x => x.Email).NotNull().WithLocalizedMessage(() => ValidationResources.EmailRequired);
        RuleFor(x => x.Email).EmailAddress().WithLocalizedMessage(() => ValidationResources.EmailValid);
        RuleFor(x => x.PhoneNumber).NotNull().WithLocalizedMessage(() => ValidationResources.PhoneNumberRequired);
        RuleFor(x => x.FullName).NotNull().WithLocalizedMessage(() => ValidationResources.FullNameRequired);
        RuleFor(x => x.CompanyName).NotNull().WithLocalizedMessage(() => ValidationResources.CompanyNameRequired);
    }
}

在Global.asax中注册

FluentValidationModelValidatorProvider.Configure();

控制器

[HttpPost]
public ActionResult UpdateUser(UserViewModel vm) {
    if (!ModelState.IsValid)
        return View(vm);

    var service = DiConfig.Resolve<IUserService>();
    service.Update(vm);
    return RedirectToAction("Index");
}

视图

<form action="@Url.Action("UpdateUser", "User")">
    @Html.ValidationSummary(true)
    <div class="form-input">
        @Html.LabelFor(m => m.Email, FormResources.Email)
        @Html.TextBoxFor(m => m.Email)
        <div class="error-message">@Html.ValidationMessageFor(m => m.Email)</div>
    </div>
    <div class="form-input">
        @Html.LabelFor(m => m.PhoneNumber, FormResources.PhoneNumber)
        @Html.TextBoxFor(m => m.PhoneNumber)
        <div class="error-message">@Html.ValidationMessageFor(m => m.PhoneNumber)</div>
    </div>
    <div class="form-input">
        @Html.LabelFor(m => m.FullName, FormResources.FullName)
        @Html.TextBoxFor(m => m.FullName)
        <div class="error-message">@Html.ValidationMessageFor(m => m.FullName)</div>
    </div>
    <div class="form-input">
        @Html.LabelFor(m => m.CompanyName, FormResources.CompanyName)
        @Html.TextBoxFor(m => m.CompanyName)
        <div class="error-message">@Html.ValidationMessageFor(m => m.CompanyName)</div>
    </div>
    <div class="form-input">
        <input type="submit" value="@FormResources.UpdateButton">
    </div>
</form>

问题

客户端验证工作完美。这里没问题。但是，我已经尝试确保即使在浏览器上禁用JS，验证也会起作用。当我提交表单时，我没想到会在页面重新加载后看到错误消息，而没有客户端验证。

但是，结果是 - 根本没有验证消息，但只有query string params在提交值的URL中。

问题

如何在禁用JavaScript时进行验证？我需要的是（当验证失败时）在帖子和页面重新加载后显示验证消息。

您可能会错过告诉MVC为特定类运行验证器的部分。 According to the docs，您可以通过修饰模型类来实现：

[Validator(typeof(UserViewModelValidation))]
public class UserViewModel {
    public String Email { get; set; }
    public String PhoneNumber { get; set; }
    public String FullName { get; set; }
    public String CompanyName { get; set; }
}

...或者通过配置ValidatorFactory：

FluentValidationModelValidatorProvider.Configure(provider => {
  provider.ValidatorFactory = new MyCustomValidatorFactory();
});
