新建一个工程。选择如图。

继续输入服务名

然后就生成对应的单元。

增加linux 平台。

完善对应的单元代码

{ Invokable implementation File for Txaliontest which implements Ixaliontest }
 
unit xaliontestImpl;
 
interface
 
uses Soap.InvokeRegistry, System.Types, Soap.XSBuiltIns, xaliontestIntf;
 
type
 
  { Txaliontest }
  Txaliontest = class(TInvokableClass, Ixaliontest)
  public
 
    function echoname(const Value:string):string; stdcall;
    function sumall(const Value:integer):integer; stdcall;
 
  end;
 
implementation
 
{ Txaliontest }
 
function Txaliontest.echoname(const Value: string): string;
begin
   result:='你好'+value;
end;
 
function Txaliontest.sumall(const Value: integer): integer;
var
  i:integer;
  isumall:integer;
begin
  isumall:=;
  for i :=  to value do
   isumall:=isumall+i;
 
  result:=isumall;
end;
 
initialization
{ Invokable classes must be registered }
   InvRegistry.RegisterInvokableClass(Txaliontest);
end.

{ Invokable interface Ixaliontest }
 
unit xaliontestIntf;
 
interface
 
uses Soap.InvokeRegistry, System.Types, Soap.XSBuiltIns;
 
type
 
  { Invokable interfaces must derive from IInvokable }
  Ixaliontest = interface(IInvokable)
  ['{20590E4A-BF8C-41AE-A630-94D2DD38EEE1}']
 
    { Methods of Invokable interface must not use the default }
    { calling convention; stdcall is recommended }
      function echoname(const Value:string):string; stdcall;
    function sumall(const Value:integer):integer; stdcall;
  end;
 
implementation
 
initialization
  { Invokable interfaces must be registered }
  InvRegistry.RegisterInterface(TypeInfo(Ixaliontest));
 
end.

编译本工程。出错了？

不要害怕，这是因为linux 上apache的引用没有加入。我们确认apache 已经在linux上安装成功。

那么我们在IDE 里面处理一下。

记住设以上的地方为True, 允许未定义的引用。

现在重新编译

OK 了

现在的任务就是在发布这个apache 模块。

这一块的内容请参照前面的文章。

配置文件如图：

启动apache.

在浏览器里面输入对应的地址，就可以显示webservice 的接口信息了。

好了，服务端搞定了。我们做一个客户端来调用一下这个服务。

直接建一个vcl application .

然后选择WDSL 导入器。

输入对应的地址。

系统会生成对应的接口文件

在主窗体放两个按钮。

implementation
 
{$R *.dfm}

begin

end;

end;
