解决方法
我已经编写了这个例子,只用一个HTTP GET,与Indy 10,希望它与Indy 9一起工作：
uses
{...} IdHTTP,IdComponent;
type
TFormMain = class(TForm)
{...}
private
{...}
procedure HttpWork(ASender: TObject; AWorkMode: TWorkMode; AWorkCount: Int64);
end;
{...}
procedure TFormMain.Button1Click(Sender: TObject);
var
Http: TIdHTTP;
MS: TMemoryStream;
begin
Http := TIdHTTP.Create(nil);
try
MS := TMemoryStream.Create;
try
Http.OnWork:= HttpWork;
Http.Get('http://live.sysinternals.com/ADExplorer.exe',MS);
MS.SaveToFile('C:\ADExplorer.exe');
finally
MS.Free;
end;
finally
Http.Free;
end;
end;
procedure TFormMain.HttpWork(ASender: TObject; AWorkMode: TWorkMode; AWorkCount: Int64);
var
Http: TIdHTTP;
ContentLength: Int64;
Percent: Integer;
begin
Http := TIdHTTP(ASender);
ContentLength := Http.Response.ContentLength;
if (Pos('chunked',LowerCase(Http.Response.TransferEncoding)) = 0) and
(ContentLength > 0) then
begin
Percent := 100*AWorkCount div ContentLength;
MemoOutput.Lines.Add(IntToStr(Percent));
end;
end;
