Question

我编写了一个C ++程序来验证Windows用户，当没有包含Poco Library（Event）时，它可以无缝地工作。我有一个无限的while循环（while（true）），当没有来自serer应用程序的请求时需要暂停。套接字读取在一个单独的线程中独立运行。

编译器：MingW 7.2

C ++标准：C ++ 14

包管理器：Msys2

架构：x64

我收到错误：

如果我删除#include <Poco/Event.h>程序正常运行而没有错误。

如果我添加#define POCO_WIN32_UTF8，我必须将LogonUser替换为LogonUserW。添加#define POCO_WIN32_UTF8时遇到的最大问题是我在::GetLastError()收到错误，说找不到功能。

LoginUser用法：

if(password.length() == 0)
        logonReturnVal = LogonUser(userName.c_str(), domain.c_str(), NULL, LOGON32_LOGON_NETWORK, LOGON32_PROVIDER_DEFAULT, &token);
    else
        logonReturnVal = LogonUser(userName.c_str(), domain.c_str(), password.c_str(), LOGON32_LOGON_NETWORK, LOGON32_PROVIDER_DEFAULT, &token);

:: GetLastError（）用法：

string Error::GetLastErrorAsString(void)
{
    //Get the error message, if any.
    DWORD errorMessageID = ::GetLastError();
    if(errorMessageID == 0)
        return string(); //No error message has been recorded

    LPSTR messageBuffer = nullptr;
    size_t size = FormatMessageA(FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM | FORMAT_MESSAGE_IGNORE_INSERTS,
                                 NULL, errorMessageID, MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), (LPSTR)&messageBuffer, 0, NULL);

    string message(messageBuffer, size);

    //Free the buffer.
    LocalFree(messageBuffer);

    return message;
}

问题是我在Poco/Event.h之前加入了windows.h。在包含导致问题的标题之前，Poco/Event.h需要定义#define POCO_WIN32_UTF8。

通过在定义windows.h之前加入#define POCO_WIN32_UTF8来解决问题，而Poco/Event.h又在包含tColor之前定义了。{/ p>

包含Poco-Library时，Windows套接字和身份验证构建失败
