变量名 | 类 型 | 静态 | 数组 | 备 注 | hSession | 整数型 | | | hFile | 整数型 | | | buffer | 字节集 | | | len | 整数型 | | | null | 文本型 | | | retVal | 字节集 | | |
hSession = API_InternetOpen (null, #INTERNET_OPEN_TYPE_PRECONFIG, null, null, 0 )如果真 (hSession ≠ #NULL )hFile = API_InternetOpenUrl (hSession, “http://img4.imgtn.bdimg.com/it/u=360413299,291033693&fm=116&gp=0.jpg”, null, 0, #INTERNET_FLAG_RELOAD, 0 )如果真 (hFile ≠ #NULL )buffer = 取空白字节集 (512 )循环判断首 ()API_InternetReadFile (hFile, buffer, 512, len )retVal = retVal + buffer 循环判断尾 (len > 0 )API_InternetCloseHandle (hFile )API_InternetCloseHandle (hSession)返回 (retVal)|
QueryFileSize | 整数型 | | |
hRequest | 整数型 | | | |
buffer = 取空白文本 (127 )API_HttpQueryInfo (hRequest, #HTTP_QUERY_CONTENT_LENGTH, buffer, 127, 0 )返回 (到整数 (buffer ))
#include <windows.h> #include <wininet.h> #pragma comment (lib, "Wininet.lib") DWORD QueryFileSize (HANDLE hFile) { DWORD len = 127; LPSTR str = new CHAR[len]; ZeroMemory (str, len); HttpQueryInfo (hFile, HTTP_QUERY_CONTENT_LENGTH, str, &len, 0); return atoi (str); } VOID HttpReadFile () { HANDLE hSession = InternetOpen (NULL, INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, NULL); if (hSession != NULL) { HANDLE hFile = InternetOpenUrl (hSession, "http://wwww.baidu.com", NULL, NULL, INTERNET_FLAG_RELOAD, NULL); if (hFile != NULL) { DWORD len; LPBYTE buffer = new BYTE[512]; do { InternetReadFile (hFile, buffer, 512, &len); RtlZeroMemory (buffer, len); } while (len > 0); } } }
源码很短直接贴.打包比较费劲
