【问题讨论】：
你也必须展示你的控制器 它说：看起来你的帖子主要是代码；请添加更多详细信息。 抱歉，我看不到您的控制器标题，只有操作 我重写了文本以通过警告 【参考方案1】：由于您在操作中使用 [ValidateAntiForgeryToken] 尝试添加 @Html.AntiForgeryToken()
<form asp-action="Edit" >
@Html.AntiForgeryToken()
<div asp-validation-summary="ModelOnly" class="text-danger"></div>
或删除 [ValidateAntiForgeryToken]
