.Net Core 调用WebService

业务描述:

  SAP系统的开发人员提供了一个根据订单号获取SAP订单的WebService。此WebService与之前的WebService有点不同,需要输入用户名及密码。

  WSDL地址:
    http://gwsapdev03.greatwall.com.cn:8000/sap/bc/srt/wsdl/bndg_EB1D857C0E8C9DF18A1F00155DF0731F/wsdl11/allinone/ws_policy/document?sap-client=830
  SOAP地址:

    http://gwsapdev03.greatwall.com.cn:8000/sap/bc/srt/rfc/sap/zws_wms_get_prdorder_data/830/zws_get_prdorder_data/zws_get_prdorder_data

  注:直接在浏览器里输入地址后会弹出输入用户名及密码的对话框。

解决思路:

  1:由于.Net Core 无法直接添加服务引用(报错),于是准备用Vs2012 ASP.Net 项目先添加服务应用,生成Reference.cs后再拷贝到.Net Core项目中来

  2:在VS2012先调用通过

  3:由于添加服务引用时,Web.config文件中会生成一些配置文件( <system.serviceModel>),需删除这部分配置代码再调试通过。

  4:最后在.Net Core 项目中调试通过。

开始:

步骤一:

  用WSDL地址添加时,提示了3次输入用户名和密码,输入后添加服务引用成功。

  用SOAP地址添加服务引用,提示错误(验证不通过)。忽略之

步骤二:开始在VS2012种写测试代码(写完感觉挺简单的,麻烦的在后面)

.Net Core 调用WebService
 protected void btnOk_Click(object sender, EventArgs e)
        {
            GreatwallSapWebService.ZWS_WMS_GET_PRDORDER_DATAClient client = new GreatwallSapWebService.ZWS_WMS_GET_PRDORDER_DATAClient();
            GreatwallSapWebService.ZwmsGetPrdorderDataRequest request = new GreatwallSapWebService.ZwmsGetPrdorderDataRequest();
            request.IPrdorder = "1179209";
            client.ClientCredentials.UserName.UserName = "WMSRFC";
            client.ClientCredentials.UserName.Password = "Wmsrfc*2020";
            Task<GreatwallSapWebService.ZwmsGetPrdorderDataResponse> responseTask = client.ZwmsGetPrdorderDataAsync(request);
            GreatwallSapWebService.ZwmsGetPrdorderDataResponse response = responseTask.Result;
        }

步骤三: 删除掉Web.config <system.serviceModel> 这个节点,继续写测试代码

配置文件:httpsTransport 删除掉S,生成出来时,运行会报错。

 <system.serviceModel>
    <bindings>
      <customBinding>
        <binding name="ZWS_GET_PRDORDER_DATA" >
          <textMessageEncoding messageVersion="Soap11" />
          <httpTransport authenticationScheme="Basic" />
        </binding>
      </customBinding>
    </bindings>
    <client>
      <endpoint address="http://gwsapdev03.greatwall.com.cn:8000/sap/bc/srt/rfc/sap/zws_wms_get_prdorder_data/830/zws_get_prdorder_data/zws_get_prdorder_data"
        binding="customBinding" bindingConfiguration="ZWS_GET_PRDORDER_DATA"
        contract="GreatwallSapWebService.ZWS_WMS_GET_PRDORDER_DATA"
        name="ZWS_GET_PRDORDER_DATA" />
    </client>
  </system.serviceModel>

可以看出这个配置信息下有个customBinding 节点,后面的代码思路就是用代码的方式替代配置项的方式。

这块走了点弯路,一开始时通过错误提示在百度上查,然后不断地尝试。浪费了一些时间。

且由于多次连接不成功后,导致SAP提供的那个账号被锁住了(一开始还没发现),于是就有个OK和error按钮。

没点一次Error按钮就再点一次OK按钮,来保证账号不被锁住。(这些都是题外话)

 

注:可以跟踪已调试通过(第一个方法),看看Client 这个变量里。见下图:

            HttpTransportBindingElement httpTransport = new HttpTransportBindingElement();
            httpTransport.AuthenticationScheme = System.Net.AuthenticationSchemes.Basic;
            TextMessageEncodingBindingElement textMessageEncoding = new TextMessageEncodingBindingElement();
            textMessageEncoding.MessageVersion = MessageVersion.Soap11;
            
            SynchronizedCollection<BindingElement> coll = new SynchronizedCollection<BindingElement>();
            coll.Add(textMessageEncoding); 
            coll.Add(httpTransport);

            System.ServiceModel.Channels.CustomBinding myBinding = new System.ServiceModel.Channels.CustomBinding(coll);
            EndpointAddress address = new EndpointAddress("http://gwsapdev03.greatwall.com.cn:8000/sap/bc/srt/rfc/sap/zws_wms_get_prdorder_data/830/zws_get_prdorder_data/zws_get_prdorder_data");

            GreatwallSapWebService.ZWS_WMS_GET_PRDORDER_DATAClient client = new GreatwallSapWebService.ZWS_WMS_GET_PRDORDER_DATAClient(myBinding, address);
          
            GreatwallSapWebService.ZwmsGetPrdorderDataRequest request = new GreatwallSapWebService.ZwmsGetPrdorderDataRequest();
            request.IPrdorder = "1179209";
            client.ClientCredentials.UserName.UserName = "WMSRFC";
            client.ClientCredentials.UserName.Password = "Wmsrfc*2020";

            Task<GreatwallSapWebService.ZwmsGetPrdorderDataResponse> responseTask = client.ZwmsGetPrdorderDataAsync(request);
            GreatwallSapWebService.ZwmsGetPrdorderDataResponse response = responseTask.Result;
          
        }

步骤三:拷贝到.Net Core 项目中
