【问题描述】：

我正在开发一个烧录引导程序，它需要从需要身份验证的 http 存储库下载先决条件。那么，我应该如何处理这个请求呢？

谢谢！

【问题讨论】：

您想提示用户输入适当的凭据，还是正在寻找一种（安全地）嵌入凭据的方法？（第二个是不可能的，但最好知道你要走哪条路）
不，不会提示用户输入凭据；我正在寻找指定凭据的方法。方法 Engine.SetDownloadSource() 已经支持，但我不知道如何使用它。参考：stackoverflow.com/questions/13346168/…

【解决方案1】：

知道了！这可以在 OnResolveSource() 事件上实现：

// variable used for authentication
static const LPCWSTR WIXSTDBA_VARIABLE_HTTP_DOWNLOAD_USER = L"HTTPDownloadUserName";
static const LPCWSTR WIXSTDBA_VARIABLE_HTTP_DOWNLOAD_PASS = L"HTTPDownloadPassword";

virtual STDMETHODIMP_(int) OnResolveSource(
    __in_z LPCWSTR wzPackageOrContainerId,
    __in_z_opt LPCWSTR wzPayloadId,
    __in_z LPCWSTR wzLocalSource,
    __in_z_opt LPCWSTR wzDownloadSource
    )
{
    int nResult = IDERROR; // assume we won't resolve source and that is unexpected.

    LPWSTR sczHTTPDwnUserName = NULL;
    LPWSTR sczHTTPDwnPassword = NULL;
    BOOL bUseHTTPAuth = FALSE;

    if (BalStringVariableExists(WIXSTDBA_VARIABLE_HTTP_DOWNLOAD_USER))
    {
        HRESULT hrUsr = BalGetStringVariable(WIXSTDBA_VARIABLE_HTTP_DOWNLOAD_USER, &sczHTTPDwnUserName);
        HRESULT hrPwd = BalGetStringVariable(WIXSTDBA_VARIABLE_HTTP_DOWNLOAD_PASS, &sczHTTPDwnPassword);
        if (SUCCEEDED(hrUsr) && SUCCEEDED(hrPwd)) bUseHTTPAuth = TRUE;
    }

    if (BOOTSTRAPPER_DISPLAY_FULL == m_command.display)
    {
        if (wzDownloadSource)
        {
            if (bUseHTTPAuth)
            {
                HRESULT hr = m_pEngine->SetDownloadSource(wzPackageOrContainerId, wzPayloadId, wzDownloadSource, sczHTTPDwnUserName, sczHTTPDwnPassword);
                nResult = SUCCEEDED(hr) ? IDDOWNLOAD : IDERROR;
            } 
            else
                nResult = IDDOWNLOAD;
        }
        else // prompt to change the source location.
        {
            // related stuff
        }
    }
    else if (wzDownloadSource)
    {
        // If doing a non-interactive install and download source is available, let's try downloading the package silently
        if (bUseHTTPAuth)
        {
            HRESULT hr = m_pEngine->SetDownloadSource(wzPackageOrContainerId, wzPayloadId, wzDownloadSource, sczHTTPDwnUserName, sczHTTPDwnPassword);
            nResult = SUCCEEDED(hr) ? IDRETRY : IDERROR;
        } 
        else
            nResult = IDDOWNLOAD;
    }
    // else there's nothing more we can do in non-interactive mode

    return CheckCanceled() ? IDCANCEL : nResult;
}

你到底在做什么？究竟是如何利用 OnResolveSource 的？
