Question

我遇到了gsoap客户端c ++调用我的简单wcf服务的问题，该服务公开了：

public double Add(double n1, double n2) {
    double result = n1 + n2;
    return result;
}

以下是我的gsoap客户端测试代码：

BasicHttpBinding_USCORERestaurantService svc;
_ns1__Add         request;
_ns1__AddResponse response;

//svc->endpoint
double n1 = 1.12;
double n2 = 2.32;

request.n1 =&n1;
request.n2= &n2;
svc.soap->keep_alive=1;
int iResult = svc.__ns1__Add(&request, &response); // response result always return 0

我在服务中有一个断点，n1的参数，n2总是0;

以下是我的wsdl文件：

Answer 1

当WCF服务总是在请求Add（int n1，int n2）时返回0时，我遇到同样的问题。经过长时间的工作，我找到了解决方案，我的解决方法是应用gSoap 2.7.16而不是最后的2.8.1_2，它完美无缺。

Answer 2

下班后，我修复了这个问题，如果你使用的是WCF，你需要在你的操作中添加一个属性，例如：

[ServiceContract]
    public interface IMyService
    {
        [OperationContract]
        [XmlSerializerFormat(Style = OperationFormatStyle.Rpc, Use = OperationFormatUse.Literal)]
        long Method1(int a, int b, long c, string d);
     }

所以gsoap可以正确地将参数值发送给服务器。

gsoap2.8客户端和wcf服务（）
