c# - 使用 WCF 端点时出现 400 错误请求响应

Question

尝试使用 HttpClient 向本地 iis 托管的 WCF 服务的端点发出请求时，我收到 400 Bad Request 响应。该调用在 .NET Core 微服务中实现，如下所示：

    private static readonly HttpClient client = new HttpClient();
    
    public async Task<ActionResponse> SomeAction(ActionRequest request, ShoppingCart shoppingCart) {

        //non-related code
 
        var requestObject = new WcfServiceRequest() {
            OrderData = shoppingCart.Order,
            VoucherCode = request.VoucherCode,
            Check = request.Check,
            Identifier = shoppingCart.Order.Identifier,
            DontGenerateNewOrdernumber = true
        };
    
        var requestContent = JsonConvert.SerializeObject(requestObject, settings);
        HttpResponseMessage serviceResponse = await client.PostAsync(new Uri("http://localhost/SomeApplicationServicePortal/Services/WcfPortalService.svc/web/SomeEndpoint"), 
        new StringContent(requestContent, Encoding.UTF8, "application/json"));

       //more non-related code

    }

另一方面，合同如下：

[DataContract]
public class WcfServiceRequest {
    [DataMember]
    public string Identifier { get; set; }
    [DataMember]
    public Order OrderData { get; set; }
    [DataMember]
    public Client ClientData { get; set; }
    [DataMember]
    public string VoucherCode { get; set; }
    [DataMember]
    public bool Check;
    [DataMember]
    public bool ExistingOrder;
    [DataMember]
    public bool DontGenerateNewOrdernumber { get; set; }
}

此刻我不知道该怎么做。如果有人帮助我解决这个问题，我将非常感激。

编辑：

其 web.config 文件中包含的 WCF serviceModel 如下：
