我正在制作我的宠物项目以熟悉 asp.net core mvc。最初，有一个控制器User负责与用户一起工作（注册、授权、密码更改和退出），还有一个方法Login负责登录。有一次，我想将控制器的名称从 to 更改为User，Account将方法的名称从Loginto更改为Sigin，并且尽可能地替换链接。基本上我有两个问题：
- 如果需要更改控制器或方法的名称怎么办，然后在整个项目中查找旧名称并更改为新名称（
Startup设置时的视图、代码、类CookieAuthenticationOptions） - 如果项目已经发展到 >=10 个控制器并且在每个控制器中 >=5 个方法
HttpGet，并且您无法记住所有这些控制器，您需要调用其中一个，该怎么办。
这是我解决问题的方法
public static class LinksConstants
{
public static class Account
{
public const String Controller = "Account";
public const String SignUpActionName = "SignUp";
public const String SignInActionName = "SignIn";
public const String ChangePasswordActionName = "ChangePassword";
public const String SignOutActionName = "SignOut";
public static readonly String SignUpLink;
public static readonly String SignInLink;
public static readonly String ChangePasswordLink;
public static readonly String SignOutLink;
static Account()
{
String mask = "/{0}/{1}";
SignUpLink = String.Format(mask , Controller , SignUpActionName);
SignInLink = String.Format(mask , Controller , SignInActionName);
ChangePasswordLink = String.Format(mask , Controller , ChangePasswordActionName);
SignOutLink = String.Format(mask , Controller , SignOutActionName);
}
}
}
public class AccountController : Controller
{
[HttpGet, AllowAnonymous, ActionName(LinksConstants.Account.SignInActionName)]
public async Task<IActionResult> SignInView([FromServices] SignInManager signInManager ,
[FromQuery] String returnUrl = null)
{
//do work
}
}
<div class="clearfix">
<a class="float-right" asp-route-returnUrl="@Model.ReturnUrl" asp-controller=@LinksConstants.Account.Controller asp-action=@LinksConstants.Account.SignUpActionName>Create account</a>
</div>
您如何在实际项目中解决此类问题？
模型
public sealed class SignInViewModel
{
#region Fields
public static readonly SignInViewModel Empty;
[Required]
[DataType(DataType.EmailAddress)]
[EmailAddress]
[Display(Name = "Email")]
public String Email { get; set; }
[Required]
[DataType(DataType.Password)]
[Display(Name = "Password")]
[Remote(action: LinksConstants.RemoteValidation.ValidationPasswordActionName , controller: LinksConstants.RemoteValidation.Controller)]
public String Password { get; set; }
[ScaffoldColumn(false), ValidateNever]
public String ReturnUrl { get; set; }
#endregion Fields
static SignInViewModel()
{
Empty = new SignInViewModel()
{
ReturnUrl = "/"
};
}
public async Task ValidationOnServer(ModelStateDictionary modelState , UserManager userManager)
{
UserEntity user = await userManager.FindByEmailAsync(Email);
if (user is null || !await userManager.CheckPasswordAsync(user , Password))
{
String message = "Invalid email or password";
modelState.TryAddModelError(nameof(Email) , message);
modelState.TryAddModelError(nameof(Password) , message);
}
}
}
看法
@using WebContacts.Models.Account;
@model SignInViewModel
@section Scripts
{
<partial name="_ValidationScriptsPartial" />
}
