Storing boost sockets in vectors

本文关键字：插座 存储      更新时间：2023-10-16

代码如下:我得到以下错误:

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));
代码:

#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，因此不能直接将原始指针压入共享指针的向量。使用下列任意一种:

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，要小心将std和boost转储到全局命名空间中。在两个命名空间中都定义了许多名称(如shared_ptr)，因此这种不加区分的污染很可能导致歧义。
