在我的项目中，我是通过搜索过滤的，在API端查询的时候可以得到数据，但是在MVC端消费API的时候没有数据。
API控制器，

[HttpGet("ListExpenseByAccountingSearch/{search}")]
public async Task<IActionResult> ListExpenseByAccountingSearch(string search)
{
    var values = await _expenseService.itemListExpenseByAccountingSearch(search);
    return Ok(values);
}

字符串
MVC控制器，

[HttpGet]
public async Task<IActionResult> ListExpenseByAccountingSearch(string search)
{
    var client = _httpClientFactory.CreateClient();
    var responseMessage = await client.GetAsync($"https://localhost:7198/api/Expense/ListExpenseByAccountingSearch/{search}");
    if (responseMessage.IsSuccessStatusCode)
    {
        var jsonData = await responseMessage.Content.ReadAsStringAsync();
        var values = JsonConvert.DeserializeObject<List<ResultExpenseByAccountingDto>>(jsonData);
        return Json(values);
    }
    return Json(new List<ResultExpenseByAccountingDto>());
}

搜索输入，

<input class="form-control form-control-sm" id="txtSearch" type="text" oninput="listExpenseBySearch()" placeholder="Search...">

AJAX ，

function listExpenseBySearch() {
     var searchText = $("#txtSearch").val();
     $.ajax({
         type: "GET",
         url: "/Management/Accounting/ListExpenseByAccountingSearch/" + searchText,
         success: function (value) {
             console.log(value);
             $("#tableExpense tbody").empty();
             var tablerow;
             $.each(value, (index, item) => {
                 tablerow = $("<tr/>");
                 tablerow.append(`<td><a class="fw-semibold text-primary">#${item.periodID}</a></td>`)
                 tablerow.append(`<td>${item.createUser}</td>`)
                 tablerow.append(`<td>${item.periodMonth}</td>`)

                 }
                 let formattedAmount = parseFloat(item.totalAmount).toLocaleString('tr-TR', { minimumFractionDigits: 2 });

我用Postman获取数据，但是在MVC端的表或控制台中没有数据。它也没有返回任何错误。
