就是在Type Library里,输出参数定义为VARIANT *
ASP里调用就是定义个变量传进去就行了
例如D里定义这么个对象
THttpRequest = class(TAutoObject, IHttpRequest)
public
//在Type Library里,类型分别为BSTR,BSTR,VARIANT_BOOL,VARIANT *,VARIANT *,VARIANT *,VARIANT *,VARIANT *
//前三个输入参数,类型可以不为VARIANT *,后5个输出参数,一定得用VARIANT *
procedure Get(const Address, URL: WideString; Redirect: WordBool;
out Status, Data, ConnectTime, GetTime, MD5: OleVariant); safecall;
end;
脚本语言调用:
Dim o
Dim IPaddress, url, autoRedirect
Dim i,s,t1,t2,md5
autoRedirect = true
set o = CreateObject("HttpTest.HttpRequest"
url = "http://dldn.icast.cn/icast/mv/samsung/44611/title.swf"
IPaddress = "222.73.237.48"
o.Get IPaddress, url, autoRedirect, i, s, t1, t2, md5
