我是編程新手，我的程式沒有出現任何錯誤，但我的登錄無效，當我輸入密碼和用戶名并單擊按鈕時，它沒有進入管理頁面 - 實際上沒有t 去任何地方并回傳登錄頁面（本身）。
我的管理操作方法具有[Authorize]屬性，我認為在資料庫中一切正常，并且資料插入了種子資料。請幫忙。

家庭控制器
[Authorize]
public IActionResult Admin()
{
return View();
}
而且我的模型驗證也不起作用（asp-validation-for在輸入中） - 我不知道為什么。
uj5u.com熱心網友回復：
您在按鈕引數中在哪里呼叫函式？
使用https://getbootstrap.com/docs/5.0/components/buttons/
-> 使用button，而不是input type="submit"。

你需要一個https://www.educba.com/button-in-asp-net/：
OnClick="Login"
uj5u.com熱心網友回復：
看看你表格的這一部分：
<div class="form-group col-12">
<input type="submit" value="enter" asp-action="Admin" asp-controller="Home" class="btn btn-outline-success form-control col-6" />
</div>
您正在向 Home Controller 中的 Admin 操作發布您的請求。您沒有將其發送到您的 AccountController。將其更改為 asp-action="Login" asp-controller="Account" 。
關于模型驗證，您應該在 HttpPost 登錄名中包含以下內容：
if(!ModelState.IsValid)
{
return View(login);
}
