程序流程如下：
1. 记录下正在运行的IIS相关服务（这样可以避免在步骤3启动原本服务器上并未开启的服务）
2. 停止上述服务
3. 开启上述服务
可以在步骤2和步骤3之间做一些事情。

GetTempFileName注意事项

修改于

调用GetTempFileName获取临时文件名的时候，GetTempFileName函数内部会自动创建这个文件。如果是调用MoveFile将文件移动到这个位置就要注意了，因为MoveFile的目的路径已经存在文件了，移动会失败。解决方法可是先DeleteFile删除文件再MoveFile移动文件，或者使用直接MoveFileEx并指定MOVEFILE_REPLACE_EXISTING参数。

使用iisreset.exe的COM接口操作IIS服务

我在实际情况中发现使用关闭Windows服务的方式重启IIS是有一定概率失败的，很可能是由超时时间导致的。使用COM组件的方式重启IIS就没有这个问题，iisreset.exe使用的就是这个COM接口。

启动、停止Windows服务

#include <windows.h>
#include <iisrsta.h>
const IID IID_IIisServiceControl =
{ 0x0E8FB8620, 0x588F, 0x11D2,
    { 0x9D, 0x61, 0x00, 0xC0, 0x4F, 0x79, 0xC5, 0xFE } };

const GUID CLSID_IisServiceControl =
{ 0x0E8FB8621, 0x588F, 0x11D2,
    { 0x9D, 0x61, 0x00, 0xC0, 0x4F, 0x79, 0xC5, 0xFE } };

int main(int argc, char* argv[])
{
    HRESULT				result;
    int					rc = -1;
    IIisServiceControl*	IisSrvCtrl = nullptr;
    
    result = CoInitializeEx(0, 0);
    if (result != S_OK)
        return 1;
    do
    {
        result = CoCreateInstance(CLSID_IisServiceControl, 
                                  nullptr, 
                                  CLSCTX_LOCAL_SERVER | CLSCTX_REMOTE_SERVER | CLSCTX_INPROC_SERVER, 
                                  IID_IIisServiceControl, 
                                  (LPVOID*)&IisSrvCtrl
        );
        if (result != S_OK)
        {
            rc = 2;
            break;
        }
        //如果IIS服务本身就是关闭状态，调用Stop函数返回的也是S_OK
        result = IisSrvCtrl->Stop(60 * 1000, TRUE);
        if (result != S_OK)
        {
            MessageBoxA(NULL, "关闭服务失败", "", 0);
            rc = 3;
            break;
        }
        //
        MessageBoxA(NULL, "成功关闭IIS服务", "", 0);
        result = IisSrvCtrl->Start(60 * 1000);
        if (S_OK != result)
        {
            MessageBoxA(NULL, "启动服务失败", "", 0);
            rc = 4;
            break;
        }
        rc = 0;
    } while (0);
    CoUninitialize();
    return rc;
}

方案一

#include <boost/archive/iterators/base64_from_binary.hpp>
#include <boost/archive/iterators/binary_from_base64.hpp>
#include <boost/archive/iterators/transform_width.hpp>

bool Base64Encode(const std::string& input, std::string& output) {
    typedef boost::archive::iterators::base64_from_binary<boost::archive::iterators::transform_width<std::string::const_iterator, 6, 8> > Base64EncodeIterator;
    std::stringstream result;
    std::copy(Base64EncodeIterator(input.begin()), Base64EncodeIterator(input.end()), std::ostream_iterator<char>(result));
    size_t equal_count = (3 - input.length() % 3) % 3;
    for (size_t i = 0; i < equal_count; i++) {
        result.put('=');
    }
    output = result.str();
    return output.empty() == false;
}

bool Base64Decode(const std::string& input, std::string& output) {
    typedef boost::archive::iterators::transform_width<boost::archive::iterators::binary_from_base64<std::string::const_iterator>, 8, 6> Base64DecodeIterator;
    std::stringstream result;
    try {
        std::copy(Base64DecodeIterator(input.begin()), Base64DecodeIterator(input.end()), std::ostream_iterator<char>(result));
    }
    catch (...) {
        return false;
    }
    output = result.str();
    return output.empty() == false;
}

方案一有问题，在使用Base64Decode解码的时候，如果输入源的末尾有“=”补位符，那么output的字符串的长度是不对的，不是实际字符串的长度，比实际的字符串长度要长（就是包含补位符的input的字符串应算出来的解码长度）。

方案二

#include <boost/archive/iterators/binary_from_base64.hpp>
#include <boost/archive/iterators/base64_from_binary.hpp>
#include <boost/archive/iterators/transform_width.hpp>
#include <boost/algorithm/string.hpp>

std::string decode64(const std::string &val) {
    using namespace boost::archive::iterators;
    using It = transform_width<binary_from_base64<std::string::const_iterator>, 8, 6>;
    return boost::algorithm::trim_right_copy_if(std::string(It(std::begin(val)), It(std::end(val))), [](char c) {
        return c == '\0';
    });
}

std::string encode64(const std::string &val) {
    using namespace boost::archive::iterators;
    using It = base64_from_binary<transform_width<std::string::const_iterator, 6, 8>>;
    auto tmp = std::string(It(std::begin(val)), It(std::end(val)));
    return tmp.append((3 - val.size() % 3) % 3, '=');
}

方案二没有方案一的那个问题。
