無法重定向到我在 asp dot net core 中的本地頁面

Question

我是asp.net core新手。 我已經使用身份登錄和注冊。 我試圖在成功登錄后重定向到我的頁面。

public async Task<IActionResult> OnPostAsync(string returnUrl = null)
    {
        returnUrl = Url.Content("~/Home/Index");

        if (ModelState.IsValid)
        {
            // This doesn't count login failures towards account lockout
            // To enable password failures to trigger account lockout, set lockoutOnFailure: true
            var result = await _signInManager.PasswordSignInAsync(Input.Email, Input.Password, Input.RememberMe, lockoutOnFailure: false);
            if (result.Succeeded)
            {
                _logger.LogInformation("User logged in.");
                return LocalRedirect(returnUrl);
            }
            if (result.RequiresTwoFactor)
            {
                return RedirectToPage("./LoginWith2fa", new { ReturnUrl = returnUrl, RememberMe = Input.RememberMe });
            }
            if (result.IsLockedOut)
            {
                _logger.LogWarning("User account locked out.");
                return RedirectToPage("./Lockout");
            }
            else
            {
                ModelState.AddModelError(string.Empty, "Invalid login attempt.");
                return Page();
            }
        }

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

下面是我的啟動文件，我在其中做了一些配置

啟動文件

 public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }
        else
        {
            app.UseExceptionHandler("/Home/Error");
            // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
            app.UseHsts();
        }
        app.UseHttpsRedirection();
        app.UseStaticFiles();

        app.UseRouting();

        app.UseAuthorization();

        app.UseAuthentication();

        app.UseEndpoints(endpoints =>
        {
            endpoints.MapControllerRoute(
                name: "default",
                pattern: "{controller=Home}/{action=Index}/{id?}");
            endpoints.MapRazorPages();
        });
    }

下面是我的Login.cshtml.cs

namespace DemoLogin.Areas.Identity.Pages.Account

    private readonly UserManager<DemoLoginUser> _userManager;

    public LoginModel(SignInManager<DemoLoginUser> signInManager, 
        ILogger<LoginModel> logger,
        UserManager<DemoLoginUser> userManager)

        _userManager = userManager;
        _signInManager = signInManager;
        _logger = logger;

    [BindProperty]
    public InputModel Input { get; set; }

    [TempData]
    public string ErrorMessage { get; set; }

    public class InputModel

        public string Email { get; set; }

        [Required]

        public string Password { get; set; }

        [Display(Name = "Remember me?")]
        public bool RememberMe { get; set; }
    }

    public async Task OnGetAsync(string returnUrl = null)
    {
        if (!string.IsNullOrEmpty(ErrorMessage))
        {
            ModelState.AddModelError(string.Empty, ErrorMessage);
        }

        returnUrl = returnUrl ?? Url.Content("~/");

        // Clear the existing external cookie to ensure a clean login process
        await HttpContext.SignOutAsync(IdentityConstants.ExternalScheme);

        ExternalLogins = (await _signInManager.GetExternalAuthenticationSchemesAsync()).ToList();

        ReturnUrl = returnUrl;
    }

    public async Task<IActionResult> OnPostAsync(string returnUrl = null)
    {
        returnUrl = returnUrl ?? Url.Content("~/");

        if (ModelState.IsValid)
        {
            // This doesn't count login failures towards account lockout

            var result = await _signInManager.PasswordSignInAsync(Input.Email, Input.Password, Input.RememberMe, lockoutOnFailure: false);
            if (result.Succeeded)
            {
                _logger.LogInformation("User logged in.");
                return LocalRedirect(returnUrl);
            }
            if (result.RequiresTwoFactor)
            {
                return RedirectToPage("./LoginWith2fa", new { ReturnUrl = returnUrl, RememberMe = Input.RememberMe });
            }
            if (result.IsLockedOut)
            {
                _logger.LogWarning("User account locked out.");
                return RedirectToPage("./Lockout");
            }
            else
            {
                ModelState.AddModelError(string.Empty, "Invalid login attempt.");
                return Page();

我已經注冊了一個用戶，然后嘗試登錄它。 但我沒有重定向到我的頁面~/Home/Index

Answer 1

我想我知道問題所在，您是否將[Authorize]屬性添加到您的 Index 方法中？

這是解決方案。

將順序更改為：

     app.UseAuthentication();
     app.UseAuthorization();

炫耀：

由於你的項目有很多錯誤，建議你新建一個項目，按照我的步驟操作。 這很簡單。

步驟1：（更改Authentication ）：

Step2:（點擊項目Add然后點擊New Scaffolded Item 。）：

第三步：（選擇身份然后添加）：

Step4（覆蓋所有文件然后添加）：

最后：遷移並運行項目。先注冊然后登錄。
