MFC如何将多张图片上传到 http://169.254.1.10:8090/api/v1/~bali/ABC0123456789

MFC可以通过使用WinINet API来实现HTTP上传文件。以下是一个基本示例代码，可以上传多张图片到指定的URL：

#include <afxinet.h>

void PostFilesToUrl(const CString& strUrl, const CStringArray& arrFilePaths)
{
    HINTERNET hInternet = InternetOpen(_T("MFC WinINet"), INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, 0);
    if (!hInternet)
        return;

    HINTERNET hConnect = InternetConnect(hInternet, _T("169.254.1.10"), 8090, NULL, NULL, INTERNET_SERVICE_HTTP, 0, 0);
    if (!hConnect)
    {
        InternetCloseHandle(hInternet);
        return;
    }

    HINTERNET hRequest = HttpOpenRequest(hConnect, _T("POST"), _T("/api/v1/~bali/ABC0123456789"), NULL, NULL, NULL, 0, 0);
    if (!hRequest)
    {
        InternetCloseHandle(hConnect);
        InternetCloseHandle(hInternet);
        return;
    }

    CString strBoundary = _T("----Boundary-") + COleDateTime::GetCurrentTime().Format(_T("%Y%m%d%H%M%S"));

    CString strContentType = _T("multipart/form-data; boundary=");
    strContentType += strBoundary;

    CString strHeaders = _T("Content-Type: ");
    strHeaders += strContentType;

    if (!HttpSendRequest(hRequest, strHeaders, strHeaders.GetLength(), NULL, 0))
    {
        InternetCloseHandle(hRequest);
        InternetCloseHandle(hConnect);
        InternetCloseHandle(hInternet);
        return;
    }

    DWORD dwBytesWritten = 0;

    for (int i = 0; i < arrFilePaths.GetCount(); i++)
    {
        CString strFilePath = arrFilePaths[i];
        CString strFileName = strFilePath.Right(strFilePath.GetLength() - strFilePath.ReverseFind('\\') - 1);

        CString strHeader = _T("\r\n--") + strBoundary + _T("\r\n");
        strHeader += _T("Content-Disposition: form-data; name=\"file\"; filename=\"");
        strHeader += strFileName + _T("\"\r\n");
        strHeader += _T("Content-Type: application/octet-stream\r\n\r\n");

        HANDLE hFile = CreateFile(strFilePath, GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);
        if (hFile == INVALID_HANDLE_VALUE)
            continue;

        DWORD dwFileSize = GetFileSize(hFile, NULL);

        if (!HttpWriteFile(hRequest, strHeader, strHeader.GetLength(), &dwBytesWritten, NULL))
        {
            CloseHandle(hFile);
            continue;
        }

        char* pBuffer = new char[dwFileSize];
        DWORD dwBytesRead = 0;

        if (!ReadFile(hFile, pBuffer, dwFileSize, &dwBytesRead, NULL))
        {
            CloseHandle(hFile);
            delete[] pBuffer;
            continue;
        }

        if (!HttpWriteFile(hRequest, pBuffer, dwFileSize, &dwBytesWritten, NULL))
        {
            CloseHandle(hFile);
            delete[] pBuffer;
            continue;
        }

        delete[] pBuffer;

        CloseHandle(hFile);
    }

    CString strFooter = _T("\r\n--") + strBoundary + _T("--\r\n");

    HttpWriteFile(hRequest, strFooter, strFooter.GetLength(), &dwBytesWritten, NULL);

    InternetCloseHandle(hRequest);
    InternetCloseHandle(hConnect);
    InternetCloseHandle(hInternet);
}

使用示例：

CStringArray arrFilePaths;
arrFilePaths.Add(_T("C:\\image1.jpg"));
arrFilePaths.Add(_T("C:\\image2.jpg"));

PostFilesToUrl(_T("http://169.254.1.10:8090/api/v1/~bali/ABC0123456789"), arrFilePaths);

这将上传`C:\image1.jpg`和`C:\image2.jpg`两张图片到指定URL。注意修改URL和文件路径为你自己的。
