熟悉么?反正我是烦透了!不管他是个什么玩意,暂且把它叫做度娘的防御机制。它很烦?跳过它!怎么跳?看代码:

procedure DeleteIECache(httpStr: string); // 清理IE缓存,IE.cookies
var 
  lpEntryInfo: PInternetCacheEntryInfo;  
  hCacheDir: LongWord;  
  dwEntrySize: LongWord;  
  cachefile: string;  
begin 
  dwEntrySize := 0;
  FindFirstUrlCacheEntry(nil, TInternetCacheEntryInfo(nil^), dwEntrySize);  
  GetMem(lpEntryInfo, dwEntrySize);  
  if dwEntrySize > 0 then
    lpEntryInfo^.dwStructSize := dwEntrySize;
  hCacheDir := FindFirstUrlCacheEntry(nil, lpEntryInfo^, dwEntrySize);
  if hCacheDir <> 0 then 
  begin 
    repeat 
      if (lpEntryInfo^.CacheEntryType) and (NORMAL_CACHE_ENTRY) = NORMAL_CACHE_ENTRY then
        cachefile := pchar(lpEntryInfo^.lpszSourceUrlName);
      if pos(httpStr, cachefile) > 0 then    //清除特定网站的cookies.例如baidu.com
        DeleteUrlCacheEntry(pchar(cachefile)); //执行删除操作  
      FreeMem(lpEntryInfo, dwEntrySize);
      dwEntrySize := 0;
      FindNextUrlCacheEntry(hCacheDir, TInternetCacheEntryInfo(nil^), dwEntrySize);  
      GetMem(lpEntryInfo, dwEntrySize);  
      if dwEntrySize > 0 then 
        lpEntryInfo^.dwStructSize := dwEntrySize;  
    until not FindNextUrlCacheEntry(hCacheDir, lpEntryInfo^, dwEntrySize);  
  end;  
  FreeMem(lpEntryInfo, dwEntrySize);  
  FindCloseUrlCache(hCacheDir);  
end;
 
procedure TForm1.Button1Click(Sender: TObject);
begin
  DeleteIECache(Edit1.Text);
end;

  熟悉么?只要百度过"delphi 删除cookies"  都应该看到过,不错,我抄来的。仅几句代码,就可以去掉度娘的衣杉(风韵犹存呐!口水)!

但是我要总结的是:我是个SB,对,是这样的。上面的代码在百度知道里面存了N年,我也看到过N次,但是我不相信他,反而去用那些一长串的代码,觉得长才专业,网上转那些无用代码的相当多,实际上没用!

好了,再给我这种菜鸟说一句:先调用DeleteIECache('baidu.com');再用个从爱好的webbrowser.go() 或者 idhttp.get() 或者......(本人真菜,不知道还有什么了)
