                binding="netTcpBinding" bindingConfiguration="netTcpEndpoint"
                contract="FlightInfoService" name="netTcpEndpoint" />
            <endpoint address="net.pipe://webapppro-v11/FlightInfoWebService/FlightInfoService.svc"
                binding="netNamedPipeBinding" bindingConfiguration="netNamedPipeEndpoint"
                contract="FlightInfoService" name="netNamedPipeEndpoint" />
            <endpoint address="http://webapppro-v11/FlightInfoWebService/FlightInfoService.svc"

                contract="FlightInfoService" name="wsHttpBindingConfiguration" />
        </client>
    </system.serviceModel>
</configuration>

当我尝试呼叫服务时：

public async void LoadCities()
{
    _client = new FlightInfoServiceClient(Maquette_MyAirport_Win8.FlightService.FlightInfoServiceClient.EndpointConfiguration.wsHttpBindingConfiguration,"http://servuucs.fr/FlightInfoWebService/FlightInfoService.svc");

    var citiesResponse = await _client.GetAllCitiesAsync(new BaseRequest());
    var  myCities = citiesResponse.Cities;
}

我抓住这个例外：

ERROR: UnAuthorizedAccess description:You are not authorized to access this service

如何设置我的ClientCredentials？

解决方法

正如@Paciv在评论中指出的,你可以通过代码来实现.使用属性 ClientCredentials.Windows设置它们,像这样：

_client.ClientCredentials.Windows.ClientCredential.Domain = "warzone42";
_client.ClientCredentials.Windows.ClientCredential.UserName = "user1428798";
_client.ClientCredentials.Windows.ClientCredential.Password = "p@ssw0rd";

在代码中设置凭据当然是不明智的.如果您没有以上述方式以编程方式设置Windows用户,我相信运行客户端的用户的凭据会被发送(这可能是更典型的情况？).

请注意,如果您在代码中设置凭据,您可能实际上正在寻找UserName authentication.
