在 post WCF 服务消耗中收到错误请求

Question

我正在使用 jquery 在 asp.net 中使用 post wcf 服务。我们可以通过用户登录和不登录来调用该服务。它在登录时运行良好。下图显示了在 fiddler 中检查的 post 请求

当我在用户登录后调用相同的服务时，它给出了错误的请求下图显示了 post 用户登录后在 fiddler 中检查的请求

在此应用程序中，我使用了身份框架。

请给我一个解决这个问题的想法。

Jquery代码：

我使用以下代码来使用 WCF 服务

 $("#btnSubmitReport").click(function () {

        // var count = document.getElementById().RatingBehavior._currentRating;
        var count = $("#<%=hdnRating.ClientID%>").val();


        if ($("input[id$='txtBannerCode']").val() == '') {
            alert('Banner Code is Required')
            $("input[id$='txtBannerCode']").focus();
        }
        else if ($('#<%= ddlIncidentType.ClientID %>').val() == "0") {
            alert('Please choose an option.')
            $('#<%= ddlIncidentType.ClientID %>').focus();
        }
        else if (count == "0") {
            alert('Driver Rating is Required.')
        }
        else if ($("textarea[id$='txtComment']").val() == '') {
            alert('Comment is Required')
            $("textarea[id$='txtComment']").focus();
        }

        else {

            ShowSendingProgress();
            var millisecondsToWait = 500;
            setTimeout(function() {

                if (checkCookie($("input[id$='txtBannerCode']").val() + $('#<%= ddlStates.ClientID %>').val()) == true) {
                    WCFJSONById();
                }
            }, millisecondsToWait);

} });

function WCFJSONById() {
    var count = $("#<%=hdnRating.ClientID%>").val();        
    var objIncident2 = {};
    objIncident2.StateAbbreviation = $('#<%= ddlStates.ClientID %>').val();
    objIncident2.BannerCode = $("input[id$='txtBannerCode']").val();
    objIncident2.IncidentTypeID = $('#<%= ddlIncidentType.ClientID %>').val();
    objIncident2.DrivingSkillID = count;
    objIncident2.Comment = $("textarea[id$='txtComment']").val();
    objIncident2.Latitude = "0";
    objIncident2.Longitude = "0";
    objIncident2.DeviceID = "";
    var browser = detectBrowser();
    objIncident2.DeviceUsed = browser.toString();

    var objIncident1 = {};
    objIncident1.objIncident = objIncident2;

    //      alert(JSON.stringify(objIncident1));



    Type = "POST";
    Url = "RoadLynkService.svc/SendIncidentReport";
    Data = JSON.stringify(objIncident1);
    ContentType = "application/json; charset=utf-8; charset-uf8;";
    DataType = "json"; ProcessData = true;
    CallService();

}



function CallService() {
    $.ajax({
        async: false,
        type: Type, //GET or POST or PUT or DELETE verb
        url: Url, // Location of the service
        data: Data, //Data sent to server
        contentType: ContentType, // content type sent to server
        dataType: DataType, //Expected data format from server
        processdata: ProcessData, //True or False
        success: function (msg) {//On Successfull service call
            ServiceSucceeded(msg);
        },
        error: ServiceFailed// When Service call fails
    });
}

Wcf 服务代码

 public string SendIncidentReport(IncidentInputParameters objIncident)
    {
        return IncidentManager.InsertIncident(objIncident.StateAbbreviation, objIncident.BannerCode, objIncident.IncidentTypeID,
            objIncident.DrivingSkillID, objIncident.Comment, Convert.ToDecimal(objIncident.Latitude), Convert.ToDecimal(objIncident.Longitude), objIncident.DeviceID, objIncident.DeviceUsed);
    }

在插入事件方法中我写了插入数据库的代码。

事件输入参数Class

 public class IncidentInputParameters
{

    public string StateAbbreviation { get; set; }


    public string BannerCode { get; set; }

    public string IncidentTypeID { get; set; }


    public string DrivingSkillID { get; set; }


    public string Comment { get; set; }


    public string Latitude { get; set; }


    public string Longitude { get; set; }


    public string DeviceID { get; set; }

    public string DeviceUsed { get; set; }
}

谢谢，purna

Answer 1

您必须传递 IncidentInputParameters 的对象。您已经使 objIncident2 成为 objIncident1 的属性，这将使 objIncident1 成为 class 并且 objIncident2 成为属性 class。

所以这将在 c# 中翻译成这样 IncidentInputParameters.Someproperty。您只需将 objIncident2 作为数据传递给 ajax 调用

Data = JSON.stringify(objIncident2);

Answer 2

我找到了答案，只是我们需要指定 crossDomainScriptAccessEnabled="false" 而不是 true

谢谢，
