.NET Core如何调SAP接口-.NET Core如何调WebService接口

情况说明

客户提供一个SAP接口，接口通过浏览器可以打开查看，如下图：

接口开发

连接接口服务

上述情况，SAP接口已就绪，现在开始开发接口调用。首先，创建 .NET Core Web项目，然后如下图，连接接口服务。

创建访问接口的服务

访问方法

接口访问服务 SAPWebSevice 完整代码

            var wsUrl = _appSetting.SAPSetting.InstoreEndpointUrl;
            var endpoint = new EndpointAddress(wsUrl);

            // 创建调用接口的工厂，注意这里泛型只能传入接口
            var factory = new ChannelFactory<ZMES_GOODSMVTChannel>(binding, endpoint);

            callClient = factory.CreateChannel();
            callClient.OperationTimeout = new TimeSpan(0, 20, 0);
