Question

我的数据参数如下所示：

 data: '{"originfieldTitle":"' + $("#txt-central-name").val() + '","newfieldTitle":"' + $("#txt-local-name").val() + '","originfieldcolumn":"' + $("#txt-central-columnname").val() + '","countryId":"' + $("#business-drop-selected").val() + '"}',

在WCF服务中，mthod看起来像：

 [SharePointPermission(SecurityAction.Demand, ObjectModel = true)]
    [WebInvoke(Method = "POST", UriTemplate = "/SaveMapping", BodyStyle = WebMessageBodyStyle.WrappedRequest, ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json)]
    public PortalResponse SaveMapping(string originfieldTitle, string newfieldTitle, string originfieldcolumn,  string countryId)
    {
    }

但是我在ajax中总是得到错误的请求它会进入错误回调。当我发送一个参数时，我可以在wcf的调试模式下看到数据。任何人都可以建议吗？我认为发送数据时遇到的一些问题可能是逗号。

AJAX

 $.ajax({
                type: "POST",
                url: url,
                data: '{"originfieldTitle":"' + $("#txt-central-name").val() + '","newfieldTitle":"' + $("#txt-local-name").val() + '","originfieldcolumn":"' + $("#txt-central-columnname").val() + '","countryId":"' + $("#business-drop-selected").val() + '"}',
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                async: true,
                processData: false,
                success: function (response) {
                    if (!response.HasError) {
                        StaplesAca.UnLockUi();
                        MappingTableAdvanced.Reload();
                        MappingFeatures.ClearNewFormData();
                    } else {
                        bootbox.alert("Something went wrong. Please try again later! Error: " + response.Message);
                        StaplesAca.UnLockUi();
                    }
                },
                error: function () {
                    bootbox.alert("Something went wrong. Please try again later!");
                    StaplesAca.UnLockUi();
                }
            });

嘿，因为你的接收器有BodyStyle = WebMessageBodyStyle.WrappedRequest 因此它应该是一个包装请求请使用ajax中的数据参数，如下所示：

data: JSON.stringify({originfieldTitle: $("#txt-central-name").val(),newfieldTitle: $("#txt-local-name").val() ,originfieldcolumn: $("#txt-central-columnname").val()
         ,countryId: $("#business-drop-selected").val()}),

带有多个参数的Ajax Post Bad请求
