问题： Delphi调用Https Webservice的问题
描述: 工具是Delphi2006
现状，使用WSDL Importer产生文件并调用相关方法，以前做成应用程序，使用正常，数据接收，以及发送数据到服务器都没有问题，由于项目需要，将原来的应用程序改成windows服务程序，用http的webservice进行测试一切正常，但是把webservice地址切换成https的就不行了，
返回错误信息：
服务器返回的信息无效或不可识别 - URL:http://（这里是webservice地址，把https解析成http了） - SOAPAction:""
请问这是什么原因，或者可以用其它什么方式调用https的webservice
