在C++中，使用WinHttp庫(kù)進(jìn)行HTTP請(qǐng)求時(shí)，可能需要對(duì)服務(wù)器的SSL/TLS證書(shū)進(jìn)行驗(yàn)證

以下是一個(gè)示例代碼，展示了如何在C++中使用WinHttp庫(kù)進(jìn)行安全證書(shū)驗(yàn)證設(shè)置：

#include<Windows.h>
#include <WinHttp.h>
#include<iostream>

int main() {
    // 初始化WinHttp
    HINTERNET hSession = WinHttpOpen(L"MyUserAgent", WINHTTP_ACCESS_TYPE_DEFAULT_PROXY, WINHTTP_NO_PROXY_NAME, WINHTTP_NO_PROXY_BYPASS, 0);
    if (!hSession) {
        std::cerr << "WinHttpOpen failed: "<< GetLastError()<< std::endl;
        return 1;
    }

    // 連接到服務(wù)器
    HINTERNET hConnect = WinHttpConnect(hSession, L"example.com", INTERNET_DEFAULT_HTTPS_PORT, 0);
    if (!hConnect) {
        std::cerr << "WinHttpConnect failed: "<< GetLastError()<< std::endl;
        WinHttpCloseHandle(hSession);
        return 1;
    }

    // 創(chuàng)建請(qǐng)求
    HINTERNET hRequest = WinHttpOpenRequest(hConnect, L"GET", L"/", NULL, WINHTTP_NO_REFERER, WINHTTP_DEFAULT_ACCEPT_TYPES, WINHTTP_FLAG_SECURE);
    if (!hRequest) {
        std::cerr << "WinHttpOpenRequest failed: "<< GetLastError()<< std::endl;
        WinHttpCloseHandle(hConnect);
        WinHttpCloseHandle(hSession);
        return 1;
    }

    // 設(shè)置安全證書(shū)驗(yàn)證選項(xiàng)
    DWORD dwOption = SECURITY_FLAG_IGNORE_UNKNOWN_CA | SECURITY_FLAG_IGNORE_CERT_DATE_INVALID | SECURITY_FLAG_IGNORE_CERT_CN_INVALID | SECURITY_FLAG_IGNORE_CERT_WRONG_USAGE;
    if (!WinHttpSetOption(hRequest, WINHTTP_OPTION_SECURITY_FLAGS, &dwOption, sizeof(dwOption))) {
        std::cerr << "WinHttpSetOption failed: "<< GetLastError()<< std::endl;
        WinHttpCloseHandle(hRequest);
        WinHttpCloseHandle(hConnect);
        WinHttpCloseHandle(hSession);
        return 1;
    }

    // 發(fā)送請(qǐng)求
    if (!WinHttpSendRequest(hRequest, WINHTTP_NO_ADDITIONAL_HEADERS, 0, WINHTTP_NO_REQUEST_DATA, 0, 0, 0)) {
        std::cerr << "WinHttpSendRequest failed: "<< GetLastError()<< std::endl;
        WinHttpCloseHandle(hRequest);
        WinHttpCloseHandle(hConnect);
        WinHttpCloseHandle(hSession);
        return 1;
    }

    // 接收響應(yīng)
    if (!WinHttpReceiveResponse(hRequest, NULL)) {
        std::cerr << "WinHttpReceiveResponse failed: "<< GetLastError()<< std::endl;
        WinHttpCloseHandle(hRequest);
        WinHttpCloseHandle(hConnect);
        WinHttpCloseHandle(hSession);
        return 1;
    }

    // 處理響應(yīng)
    // ...

    // 清理資源
    WinHttpCloseHandle(hRequest);
    WinHttpCloseHandle(hConnect);
    WinHttpCloseHandle(hSession);

    return 0;
}

在這個(gè)示例中，我們?cè)O(shè)置了WINHTTP_OPTION_SECURITY_FLAGS選項(xiàng)，忽略了未知的CA、證書(shū)日期無(wú)效、證書(shū)CN無(wú)效和證書(shū)用途不正確的錯(cuò)誤。這些選項(xiàng)可以根據(jù)實(shí)際需求進(jìn)行調(diào)整。

請(qǐng)注意，這個(gè)示例僅用于演示目的，實(shí)際應(yīng)用中應(yīng)該根據(jù)需要進(jìn)行適當(dāng)?shù)腻e(cuò)誤處理和資源管理。
