在 ASP.NET 中使用 SAP Web 服务失败

Question

我正在开发一个 Web 服务，该服务将使用 .NET 在 SAP 中创建订单。现在，当我运行下面的代码时，我没有收到任何错误，也没有创建订单。我希望有人能提供帮助。

    string message = "";

    // create initial connection
    Z_SALESORDER_CREATE createOrder = new Z_SALESORDER_CREATE();

    try
    {
        NetworkCredential cred = new NetworkCredential("password", "username");

        createOrder.Url = "http://saphost:8010/sap/bc/srt/wsdl/bndg_d0823E1C21F1A334DSE0001555D658D08/wsdl11/allinone/ws_policy/document?sap-client=110";
        createOrder.Credentials = cred;
    }
    catch (Exception ex){
        message = "An error occured." + ex.Message;
    }

Answer 1

问题是我需要构建一个数组并将其插入到对象中。见下文。

Bapisdhd1 order_header_in = new Bapisdhd1();
order_header_in.DocType = "OR";
order_header_in.CollectNo = "1109512";
order_header_in.SalesOrg = "10090";
order_header_in.DistrChan = "100";
order_header_in.Division = "000";
order_header_in.DlvBlock = "020";
order_header_in.PurchNoC = "E-COMM ORDER TEST ORDER";
newOrder.OrderHeaderIn = order_header_in;

我还需要一些东西将 zSalesOrderCreate 对象绑定回 Z_SALESORDER_CREATE 方法。

    ZSalesorderCreateResponse res = createOrder.ZSalesorderCreate(newOrder);

虽然我不是 .Net 方面的专家，但这里有一些奇怪的事情。 BapiRet2 不是一个方法，而是一个类，并且 R/3 中有一个同名的结构，通常用于获取有关函数调用执行的信息...

我认为您只是创建了一个变量，该变量将/ 应该包含您的网络服务的答案，并且由于您不调用后者，因此该变量为空...因此空的错误消息...

考虑

Answer 3

您没有收到任何消息，因为您从未致电该服务。代理类 Z_SALESORDER_CREATE 应该有一个具有相同或几乎相同名称的方法，该方法实际上调用服务。 BAPIRET2 只是一个包含服务返回消息的结构。准备调用参数，使用这些参数调用服务方法，然后检查 BAPIRET2 结构以获取结果。
