Delphi 的 WSDL 导入问题

Question

我正在尝试使用路透社网络服务，但在构建示例程序以访问该网络服务时出现错误。我正在使用 Delphi 2010，wsdl 位于 https://hosted.datascopeapi.reuters.com/datascopeapi/v1/extractionservice.asmx?wsdl。

导入 WSDL 后，接口定义为：

     ExtractionService = interface(IInvokable)
  ['{CD3DF44F-6D8E-C594-D58C-6A258701D678}']

下面定义的初始化似乎定义正确，但每当它引用 ExtractionService 时我都会收到错误消息，就好像导入没有正确定义 IInvokable 接口一样，但我看不出有什么不正确的地方。第一个错误在针对 Typeinfo(ExtractionService) 的 registerinterface 行上显示（E2089 无效类型转换），每当引用 ExtractionService 时都会显示其他错误。

Answer 1

TypeInfo 是 System unit 中的函数。

我检查了我使用 wsdl 的应用程序，TypeInfo 从系统单元中用作函数。请尝试在您的代码中重构由 Delphi 生成的 TypeInfo class 或将系统单元名称添加到所有 TypeInfo铸造使其成为系统单元的功能。

InvRegistry.RegisterInterface(TypeInfo(ExtractionService), 'http://reuters.com/datascopeselect/ExtractionService/v1/', 'UTF-8');

改成这样

InvRegistry.RegisterInterface(System.TypeInfo(ExtractionService), 'http://reuters.com/datascopeselect/ExtractionService/v1/', 'UTF-8');

我试过第二种方式，编译成功。
