通过 AJAX 将对象传递给 API MVC C#

Question

我正在尝试将一个对象传递给我的 API，但它一直在 API 中将该对象显示为 NULL。

我的 Ajax 调用：

$.ajax({
   type: "GET",
   url: url,
   data: tranData,
   dataType: "json",
   success: function(response){
   var itemcount = response.itemsCount;
   var dataReturned = response.data;
}});

我的 API 方法：

[HttpGet]
        [Route("Api/ReportApi/SummaryReport")]
        public IHttpActionResult SummaryReport(JObject tranData)
        {     

            dynamic oData = tranData;
            BankTransactionsViewModelResults transactions = new BankTransactionsViewModelResults();

            transactions = oData;

            var summarisedTransactions = SummariseResults(transactions.BankTransactionsViewModelList, "Test Ref");

            var response = new
            {
                data = summarisedTransactions,
                itemsCount = summarisedTransactions.Count(),
            };

            return Request.GetOKRequest(response);
        }

我试图传递的对象：

如何将其传递给我的 API？ tranData 显示为 null 但在发送之前我可以看到数据在那里......？我从外部 API 调用中获取这些数据并从响应中获取：

var tranData = JSON.parse(req.response);

Answer 1

首先创建一个类 id,accountId,clientId,agentId 等等你传递的内容

接下来创建类的对象

[HttpGet]
    [Route("Api/ReportApi/SummaryReport")]
    public IHttpActionResult SummaryReport(Class classobj)
    { your code here  }

在ajax之后 你需要发送json数据格式

like tranData{{"id":16,"accountId":11111000010,"clientId":1 like so on}

Answer 2

如果你想使用HttpGet 来完成请求，你将不得不使用严格类型的对象，就像StackOverflow question 中提到的那样。您可以将您的方法签名更改为以下内容

[HttpGet]
[Route("Api/ReportApi/SummaryReport")]
public IHttpActionResult SummaryReport([FromUri]YourCustomClass tranData)
{
    // your code
}

更好的选择是使用HttpPost。 在这种情况下，您将不得不使用JToken 而不是JObject。这是您的签名的样子

[HttpPost]
[Route("Api/ReportApi/SummaryReport")]
public IHttpActionResult SummaryReport([FromBody]JToken tranData)
{
    BankTransactionsViewModelResults transactions = tranData.ToObject<BankTransactionsViewModelResults>();

    // other processing code
    ....
}
