我已经尝试了两个多小时，试图找出这个数据库出了什么问题。我已经尝试了一切。从重新安装服务器、重新启动进程、重新启动等等。尝试连接时它一直给我这个错误：

const serverSelectionError = new ServerSelectionError();
                               ^

        maxWireVersion: 0,
        roundTripTime: -1, …

当我尝试在项目中包含任何单标头库（此处我使用HTTPRequest）时，它不断向我显示 LNK2019 错误。

这是我的代码：

#include "HTTPRequest.hpp"

void main()
{
    http::Request request{ "http://test.com/test" };
    const auto response = request.send("GET");
    std::cout << std::string{ response.body.begin(), response.body.end() } << '\n';
}

这是我的项目设置的问题吗，因为这些库应该是单个 h/hpp 文件？
