Question

我收到了以下AJAX请求：

var recordToRevert = $(this);
var umbrellaId = $(this).data("id");
var requestData = {
    umbrellaId: umbrellaId,
};

$.ajax({
    url: "/Express2/api/BenefitBank/RevertTransactionUmbrella",
    type: "POST",
    dataType: 'json',
    contentType: 'application/json; charset=utf-8',
    data: JSON.stringify(requestData),
    headers: {
        "Authorization-Token": "7,181,22",
        "CentreNumber": "0"
    }
}).done(function (data) {
    if (data.FoundRevertableTransactions) {
        recordToRevert.parent().html("<span class=\"success\">Reverted</span)");
    } else {
        alert('Umbrella NOT reverted');
    }
}).fail(function () {
    alert('Umbrella NOT reverted');
});

我将它发送到MVC控制器/动作：

[HttpPost]
[ActionName("RevertTransactionUmbrella")]
public HttpResponseMessage PostRevertTransactionUmbrella(Int64 umbrellaId)
{
    if (ModelState.IsValid)
snip...

这是我得到的回应。

{"Message":"No HTTP resource was found that matches the request URI 'http://localhost/Express2/api/BenefitBank/RevertTransactionUmbrella'.","MessageDetail":"No action was found on the controller 'BenefitBank' that matches the request."}

我设置了一个断点，控制器动作没有被击中。我想知道我是不是正确发送了JSON？

此请求有效：

$.ajax({
    url: "/Express2/api/BenefitBank/GetRequestObjects",
    type: "GET",
    dataType: 'json',
    contentType: 'application/json; charset=utf-8',
    //data: JSON.stringify(requestData),

[HttpGet]
[ActionName("GetRequestObjects")]
public HttpResponseMessage GetRequestObjects()
{
    return Request.CreateResponse(HttpStatusCode.Accepted, new BenefitBankRequestObjects());
}

看起来控制器正在被两个请求命中，但是，第一个动作没有被击中？

Answer 1

您必须传递等同于Int64 umbrellaId的查询字符串或将其默认值设置为零。

Answer 2

尝试更改以下网址：

url: "/Express2/api/BenefitBank/RevertTransactionUmbrella"

到：

url: "/Express2/api/BenefitBank/PostRevertSingleTransaction"

POST Json到MVC控制器 - 在控制器上找不到任何操作
