Delphi解析FTP地址的方法

 procedure TForm1.FTPAnalysis(S:string;var UserName,Password,IP,FileName:String;var DirList:TStringList); var i,j:integer; strAuthorization,strAddr,strDirFile:string; //授权信息 begin UserName:= 'anonymous'; Password:= 'test@test.com'; IP := ''; strAddr := Copy(S,7,length(S)-6); //取得ftp://之后的部分 //S 格式必须是类似ftp://rec:ooo@192.168.76.11/20050418/abcdef.vox， //或ftp://192.168.76.11/...... i := Pos('@',S); if(i>0) then begin strAuthorization := Copy(S,7,i-7); //只取帐号密码字段 j:=Pos(':',strAuthorization); if(j<1)then exit; UserName := Copy(strAuthorization,1,j-1); PassWord := Copy(strAuthorization,j+1,length(strAuthorization)-j); end; i := Pos('@',strAddr); j:=Pos('/',strAddr); if(j>0) then IP := Copy(strAddr,i+1,j-i-1);//获得IP地址 strDirFile := Copy(strAddr,j+1,length(strAddr)-j); DirList.Delimiter := '/'; DirList.DelimitedText := strDirFile;//获得目录列表 FileName := DirList[DirList.count-1];//最后部分为文件名 DirList.Delete(DirList.Count-1); end;
