IDFTP.connect 函数中有这么一段
if IsSiteZONESupported then begin
if SendCmd('SITE ZONE') = 210 then begin {do not localize}
if LastCmdResult.Text.Count > 0 then begin
LBuf := LastCmdResult.Text[0];
// some servers (Serv-U, etc) use a 'UTC' offset string, ie
// "UTC-300", specifying the number of minutes from UTC. Other
// servers (Apache) use a GMT offset string instead, ie "-0300".
if TextStartsWith(LBuf, 'UTC-') then begin {do not localize}
FTZInfo.GMTOffset := MDTMOffset(Copy(LBuf, 4, MaxInt));
end else begin
FTZInfo.GMTOffset := GmtOffsetStrToDateTime(LBuf);
end;
FTZInfo.FGMTOffsetAvailable := True;
end;
end;
end;使用IDFTP.connect 连接 linux主机时。遇到 LBuf 返回值是UTC-2147483647 ,这时MDTMOffset(Copy(LBuf, 4, MaxInt)); 就会range check error;MDTMOffset函数代码是
function MDTMOffset(const AOffs : String) : TDateTime;
{$IFDEF USE_INLINE} inline; {$ENDIF}
var
LOffs : Integer;
begin
LOffs := IndyStrToInt(AOffs);
{We use ABS because EncodeTime will only accept positve values}
Result := EncodeTime(Abs(LOffs) div 60, Abs(LOffs) mod 60, 0, 0);
if LOffs > 0 then begin
Result := 0 - Result;
end;
end;
EncodeTime的参数类型是word,所以返回值超过65535就肯定出错。为什么会这样,难道都不会遇到会有这种返回值?还是我的INDY10的IDFTP哪里没配置好?
像IDHTTP,,我根据网址获取字符类型的返回值会乱码。。
然后我看了一下它的代码,数据是从WEB服务器返回的是流对象,从流对象转换成字符串这一步出错了。
比如本来我可以:AReturnStr:=Trim(FHttpClient.Get('http://fw.qq.com/ipaddress'))
但在delphi2010的indy10下,我必须得:
FHttpClient.Get('http://fw.qq.com/ipaddress', LStream, []);
LStream.Position := 0;
ZeroMemory(@AnsiArray[0],256);
LStream.ReadBuffer(AnsiArray[0],LStream.Size);
AReturnStr:=AnsiArray;
