发布了Wininet库忽略Https证书文章之后有朋友问我如果使用WINHTTP发起忽略证书的方法,
下列粘出代码可以看到跟Wininet是一样的不在过多赘述不懂的朋友可以看我发的链接说明。C发起Https请求

}
WINHTTP使用TLS协议版本
详细很多朋友使用WINHTTP是为了在低版本系统运行比如WIN7或2008这些系统使用TLS 1.0/1.1
无法使用Wininet库的TLS 1.2因此使用WINHTTP下面粘出代码是低版本修改了TLS的库代码#include Windows.h
#include Winhttp.h
#include stdio.h#pragma comment(lib, winhttp.lib)#define TRANSFER_SIZE 1024bool PerformHttpRequest() {HINTERNET hSession WinHttpOpen(L, WINHTTP_ACCESS_TYPE_DEFAULT_PROXY, WINHTTP_NO_PROXY_NAME, WINHTTP_NO_PROXY_BYPASS, 0);if (!hSession) {return false;}// 设置要使用的协议 TLS 1.1,需要注意服务端也需要支持TLS 1.1否则无法使用DWORD dwFlags WINHTTP_FLAG_SECURE_PROTOCOL_TLS1_1;if (!WinHttpSetOption(hSession, WINHTTP_OPTION_SECURE_PROTOCOLS, dwFlags, sizeof(dwFlags))) {WinHttpCloseHandle(hSession);return false;}//lpszServerName 是IP或者域名LPCWSTR lpszServerName L192.168.99.99;//nServerPort 端口INTERNET_PORT nServerPort 443;HINTERNET hConnect WinHttpConnect(hSession, lpszServerName, nServerPort, 0);if (!hConnect) {WinHttpCloseHandle(hSession);return false;}HINTERNET hRequest WinHttpOpenRequest(hConnect, LGET, L/Login, NULL, WINHTTP_NO_REFERER, WINHTTP_DEFAULT_ACCEPT_TYPES, WINHTTP_FLAG_SECURE);if (!hRequest) {WinHttpCloseHandle(hConnect);WinHttpCloseHandle(hSession);return false;}BOOL bResult WinHttpSendRequest(hRequest, WINHTTP_NO_ADDITIONAL_HEADERS, 0, WINHTTP_NO_REQUEST_DATA, 0, 0, 0);if (!bResult GetLastError() ERROR_WINHTTP_SECURE_FAILURE) {//忽略所有异常Https CA证书问题// SECURITY_FLAG_IGNORE_ALL_CERT_ERRORS 也可以DWORD dwFlags SECURITY_FLAG_IGNORE_UNKNOWN_CA |SECURITY_FLAG_IGNORE_CERT_WRONG_USAGE |SECURITY_FLAG_IGNORE_CERT_CN_INVALID |SECURITY_FLAG_IGNORE_CERT_DATE_INVALID;WinHttpSetOption(hRequest, WINHTTP_OPTION_SECURITY_FLAGS, dwFlags, sizeof(dwFlags));bResult WinHttpSendRequest(hRequest, WINHTTP_NO_ADDITIONAL_HEADERS, 0, WINHTTP_NO_REQUEST_DATA, 0, 0, 0);}if (!bResult) {WinHttpCloseHandle(hRequest);WinHttpCloseHandle(hConnect);WinHttpCloseHandle(hSession);return false;}bResult WinHttpReceiveResponse(hRequest, NULL);if (!bResult) {WinHttpCloseHandle(hRequest);WinHttpCloseHandle(hConnect);WinHttpCloseHandle(hSession);return false;}wchar_t szBuff[TRANSFER_SIZE];DWORD dwReadSize;bResult WinHttpQueryHeaders(hRequest, WINHTTP_QUERY_RAW_HEADERS_CRLF, WINHTTP_HEADER_NAME_BY_INDEX, szBuff, dwReadSize, WINHTTP_NO_HEADER_INDEX);if (!bResult) {WinHttpCloseHandle(hRequest);WinHttpCloseHandle(hConnect);WinHttpCloseHandle(hSession);return false;}wprintf(L%ws\n, szBuff);DWORD dwBytesAvailable;bResult WinHttpQueryDataAvailable(hRequest, dwBytesAvailable);if (!bResult) {WinHttpCloseHandle(hRequest);WinHttpCloseHandle(hConnect);WinHttpCloseHandle(hSession);return false;}if (dwBytesAvailable TRANSFER_SIZE) {wprintf(LData too long %d /b\n, GetLastError(), dwBytesAvailable);WinHttpCloseHandle(hRequest);WinHttpCloseHandle(hConnect);WinHttpCloseHandle(hSession);return false;}DWORD dwBytesRead;ZeroMemory(szBuff, TRANSFER_SIZE);bResult WinHttpReadData(hRequest, szBuff, dwBytesAvailable, dwBytesRead);if (!bResult) {WinHttpCloseHandle(hRequest);WinHttpCloseHandle(hConnect);WinHttpCloseHandle(hSession);return false;}printf(%s\n, szBuff);WinHttpCloseHandle(hRequest);WinHttpCloseHandle(hConnect);WinHttpCloseHandle(hSession);return true;
}int main() {if (PerformHttpRequest()) {return 0;}else {return 1;}
}
