将升压套接字存储在向量中[关闭]

这是代码。我收到以下错误：

In member function ‘void socks4Server::listener(int)’:
sock4.cpp:16:49: error: no matching function for call to ‘std::vector<boost::shared_ptr<boost::asio::basic_stream_socket<boost::asio::ip::tcp>>>::push_back(boost::asio::ip::tcp::socket*)’ sockets.push_back(new tcp::socket(io_service));         

Code:

#include <iostream>
#include <vector>
#include <boost/asio.hpp>
#include <boost/thread/thread.hpp>
using boost::asio::ip::tcp;
using namespace boost;
using namespace std;

class socks4Server{
public:
    boost::asio::io_service io_service;
    bool online;

    void listener(int port){
        tcp::acceptor accept(io_service,tcp::endpoint(tcp::v4(),port));
        vector<shared_ptr<tcp::socket> > sockets;
        while(online){
            sockets.push_back(new tcp::socket(io_service));
            cout<<"new socket thing";
        }
    }

    socks4Server(int port){
        online=true;
        std::thread listen(&socks4Server::listener,this,port);
        listen.detach();
    }
};

int main(){
    socks4Server server(8080);
}

没有从原始指针到共享指针的隐式转换，因此您不能直接将原始指针推送到共享指针向量上。使用以下其中一项：

sockets.push_back(shared_ptr<tcp::socket>(new tcp::socket(io_service)));
sockets.push_back(make_shared<tcp::socket>(io_service));
sockets.emplace_back(new tcp::socket(io_service));  // C++11 or later

另外，倾倒两者时要小心std and boost进入全局命名空间。有很多名称（例如shared_ptr) 在两个命名空间中都定义了，因此这种不加区别的污染很可能会导致歧义。
