Question

我们正试图从客户端调用web-api。 web api包含一个Request类，其Amount为十进制。我们试图传递一个小数，并从webapi和状态返回相同的数量。

问题是 web-api无法收到金额。当我们尝试使用webapi附加时，我们在Request类的Amount字段中只看到null。
在这方面的任何帮助都会很棒。

以下是我们从客户端打电话的方式

    var requestMessage = { RequestSale: { Amount: '100.545M' } };        
    var request = {
        type: "POST",            
        contentType: "application/json;charset=utf-8",
        datatype: "json",
        url: "http://<machinename>/Demo/api/monthlySales/InsertMonthlySales",
        successCallback: successCallback,
        errorCallback: errorCallback,
        filterCriteria: null,            
        data: JSON.stringify(requestMessage)
        //header: { key: "Accept", value: "application/json" },
    };

    utilityTest.getData(request);
    expect(true, true);

utilityTest.getData（request） - 这使得实际调用，下面是代码

 utilityTest.getData = function (request) {
    $.ajax({
        type: request.type,
        contentType: request.contentType,
        datatype: request.datatype,
        url: request.url,
        data: request.data,
        cache : false,
        beforeSend: function (xmlHttpRequest) {            
                if (request.header) {
                    xmlHttpRequest.setRequestHeader(request.header.key, request.header.value);
                }                            
        },
        success: function (data, textStatus, xmlHttpRequest) {
            if (request.successCallback) {
                request.successCallback(data, request.filterCriteria);
            }
        },
        error: function (xmlHttpRequest, textStatus, errorThrown) {
            if (request.errorCallback)
                request.errorCallback(xmlHttpRequest, textStatus, errorThrown);
        }    });

}

Web-api方法

[HttpPost]
        public ResponseSale InsertMonthlySales(RequestSale sale)
        {
            var curMonth = DateTime.UtcNow.Month;
            var salesAmount = Convert.ToDecimal(sale.Amount);
            ResponseSale response = new ResponseSale();
            response.Amount = salesAmount;
            response.Id = curMonth;

            if (monthlySales.ContainsKey(curMonth))
            {
                monthlySales[curMonth] += salesAmount;
            }
            else
            {
                monthlySales.Add(curMonth, salesAmount);
            }
            response.Status = "InsertMonthlySales";
            return response;

}

web-api的请求/响应合同

namespace DemoContracts.Object
{
    [System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true, Namespace = "http://DemoSchema.ContractSale")]
    [System.Xml.Serialization.XmlRootAttribute(Namespace = "http://DemoSchema.ContractSale", IsNullable = false)]  
    public class RequestSale {           
        public decimal Amount { get; set; }          
    }
}

namespace DemoContracts.Object
{
    [System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true, Namespace = "http://DemoSchema.ContractSale")]
    [System.Xml.Serialization.XmlRootAttribute(Namespace = "http://DemoSchema.ContractSale", IsNullable = false)]
    public class ResponseSale
    {        
        public string Status { get; set; }     
        public decimal Amount { get; set; }        
        public int Id { get; set; }        
    }

}

- 从IE中捕获的JSON 请求机构： {＆＃34; RequestSale＆＃34; {＆＃34;量＆＃34;：100.545}}

回应机构 {＆＃34;状态＆＃34;：＆＃34; InsertMonthlySales＆＃34;＆＃34;量＆＃34;：0.0＆＃34;标识＆＃34;：9}

在Web API中，InsertMonthSales请求对象RequestSale.Amount始终为0.我们没有获得传递的100.545值

通过POST方法从客户端调用Web API失败
