使用CInternetSession和CHttpFile提取网页源码

来源:转载

程序界面:

为编辑框添加一个对应的变量:m_sUrl,再为Button1添加点击事件,主要代码如下:

void CGetHtmlCodeDlg::OnButton1(){ CString sHtml; UpdateData(); GetHtmlCode(m_sUrl, sHtml); WritetoFile(sHtml); MessageBox("提取网页源码完成");} void CGetHtmlCodeDlg::GetHtmlCode(const CString url, CString &html){ CInternetSession session; CHttpFile * file = NULL; try { file = (CHttpFile *)session.OpenURL(url); if(file) { CString line; while(file->ReadString(line) != NULL) { html += line + "/n"; } file->Close(); } } catch (CInternetException* e) { e->Delete(); html = "CInternet Exception"; } file = NULL; session.Close();} BOOL CGetHtmlCodeDlg::WritetoFile(const CString& sValue){ CString sFile = GetExePath() + "//1.html"; CStdioFile file; if(file.Open(sFile, CFile::modeCreate | CFile::modeWrite | CFile::modeNoTruncate)) { file.SeekToEnd(); // 移动文件指针到末尾 file.WriteString(sValue); file.Close(); } return FALSE;} CString CGetHtmlCodeDlg::GetExePath(){ char sFileName[256] = {0}; CString sPath = _T(""); GetModuleFileName(AfxGetInstanceHandle(), sFileName, 255); sPath.Format("%s", sFileName); int pos = sPath.ReverseFind('//'); if(pos != -1) sPath = sPath.Left(pos); else sPath = _T(""); return sPath;}
