错误请求 400 状态

Question

url = "/IPM/KPI/Add"; input = new FormData($('#frmKPI').get(0)) ;

PostAjax: function (isForm, url, input, divErrID, btnID, isSuccessFunction, isFailedFunction, NoModalAlert, isAsync)
{
    var contentType = isForm ? false : "application/json;";
    var processData = isForm ? false : true;

    $(btnID).prop("disabled", true);
    Loading(true);
    $.ajax({
        url: url,
        type: "POST",
        data: input,
        async: isAsync == null || isAsync == undefined ? false : isAsync,
        dataType: "json",
        headers: { "RequestVerificationToken": $('input[name="__RequestVerificationToken"]').val() },
        contentType: contentType,
        processData: processData,
        success: function (data) {
            if (data.IsSuccess) {
                if (isSuccessFunction != null)
                    isSuccessFunction(data);
    
                if (!NoModalAlert)
                    ModalAlert(MODAL_HEADER, data.Result);
    
                $(divErrID).html("");
            } else {
                var msg = "";
                if (data.IsListResult == true) {
                    for (var i = 0; i < data.Result.length; i++) {
                        msg += data.Result[i] + "<br />";
                    }
                } else {
                    msg += data.Result;
                }
                ModalAlert(MODAL_HEADER, msg);
                if (isFailedFunction != null)
                    isFailedFunction();
            }
            $(btnID).prop("disabled", false);
            Loading(false);
        },
        error: function (jqXHR, textStatus, errorThrown) {
            console.log("AJAX Error:", jqXHR.status, jqXHR.statusText);
            console.log("Response Text:", jqXHR.responseText);
            if (isFailedFunction != null)
                isFailedFunction();
            Loading(false);
            $(btnID).prop("disabled", false);
            ModalAlert(MODAL_HEADER, jqXHR.responseText);
        },
    });

}

请帮助，我尝试将数据转换为字符串化，但它不起作用。基本上我正在使用 .net core razor web-api，并且我正在尝试在保存表单时发布表单，并且应该转到我的 Add.cshtml.cs (handler = OnPostAsync)

Answer 1

如果要调用

Add.cshtml.cs

中的webapi方法，我们需要修改URL，例如

https://your_sitename.com/Add?handler=methodname

。

我的测试代码在Index.cshtml.cs

using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Mvc.RazorPages;

namespace WebApplication2.Pages
{
    public class IndexModel : PageModel
    {
        private readonly ILogger<IndexModel> _logger;

        public IndexModel(ILogger<IndexModel> logger)
        {
            _logger = logger;
        }

        public void OnGet()
        {

        }
        public IActionResult OnGetApi()
        {
            var data = new { Message = "Hello from API" };
            return new JsonResult(data);
        }
        public IActionResult OnPostAApi()
        {
            var data = new { Message = "Hello from API" };
            return new JsonResult(data);
        }
    }
}

Get Request测试结果（方法名为Api）

Post请求测试结果（方法名称为AApi）
