有人可以帮助我理解为什么页面远程验证会阻止 asp 处理程序触发吗？

Question

我在这里面临一个奇怪的问题。

我有一个页面，我在其中设置了 PageRemote 属性来验证字段，在同一页面上，我有 2 个按钮，每个按钮使用 asp-page-handler 属性调用不同的处理程序（1 个用于更新内容，另一个用于更新内容）删除它）。

如果我删除 PageRemote 验证，两个按钮的处理程序都会按预期触发，但是当我在页面上保留 PageRemote 验证时，不会调用按钮特定的处理程序，尽管 PageRemote 处理程序已正确触发。

此外，当在页面上保留 PageRemote 验证时，如果我强制其验证返回 false，则随后按钮会触发其各自的处理程序，但如果我不强制它，则行为如前所述，其中处理程序不是触发。

有人可以解释一下在同一页面上使用这两个东西是否有问题，和/或如何克服这个问题？

以下是页面代码的示例：

public class EditModel : PageModel
{
    
    private IConfiguration _configuration;

    [Required(ErrorMessageResourceType = typeof(ErrorMessages),
        ErrorMessageResourceName = nameof(ErrorMessages.SlugRequired))]
    [MinLength(3, ErrorMessageResourceType = typeof(ErrorMessages),
        ErrorMessageResourceName = nameof(ErrorMessages.SlugMinLength))]
    [MaxLength(128, ErrorMessageResourceType = typeof(ErrorMessages),
        ErrorMessageResourceName = nameof(ErrorMessages.SlugMaxLength))]
    [RegularExpression(@"^[0-9a-zA-Z_/-]*$", ErrorMessageResourceType = typeof(ErrorMessages),
        ErrorMessageResourceName = nameof(ErrorMessages.SlugAllowedCharacters))]
    [PageRemote(ErrorMessageResourceType = typeof(ErrorMessages),
        ErrorMessageResourceName = nameof(ErrorMessages.SlugDuplicate),
        AdditionalFields = "__RequestVerificationToken,GenericContentDTO.GenericContent.GenericContentId",
        HttpMethod = "post",
        PageHandler = "CheckSlug")]
    [Display(Name = "URL Title")]
    [BindProperty]
    public string Slug { get; set; }

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

    [BindProperty]
    public GenericContentDTO GenericContentDTO { get; set; }

    public EditModel(IConfiguration configuration)
    {
        _configuration = configuration;
    }

    public IActionResult OnGet(Guid genericContentId)
    {
        if (genericContentId.ToString() == "")
        {
            return NotFound();
        }

        ...
        Code to load content
        ...

        return Page();

    }

    public async Task<IActionResult> OnPostUpdate()
    {

        if (!ModelState.IsValid)
        {
            return Page();
        }

        ...
        Code to update content
        ...

        return RedirectToPage(new { GenericContentId = GenericContentDTO.GenericContent.GenericContentId });

    }

    public IActionResult OnPostDelete()
    {

        ...
        Code to delete content
        

    }

    public JsonResult OnPostCheckSlug()
    {

        var token = HttpContext.Session.GetString("APIAuthorizationToken");

        CheckSlugDTO CheckSlug = new CheckSlugDTO
        {
            Slug = Slug,
            ContentId = GenericContentDTO.GenericContent.GenericContentId,
            Exists = true
        };

        CheckSlug = APICommunicationHelper.PostData<CheckSlugDTO>(CheckSlug, _configuration["AppConfigs:APIAddress"] + "api/CheckGenericContentSlugExistance", token);

        return new JsonResult(!CheckSlug.Exists);
    }
}

以及 Razor 代码的示例：

@page "{GenericContentId:Guid}"
@model MyProject.Pages.Generic_Contents.EditModel

</ul>
