为什么boost在这种情况下不创建线程（C2248），以及如何创建它？
|
所以我有这样的代码：
using namespace boost::asio::ip;
using namespace std;
void request_response_loop(boost::asio::ip::tcp::socket& socket)
{
http_request request(socket);
http_response response;
response.body = \"<head></head><body><h1>It Rocks!</h1></body>\";
response.send(socket);
socket.close();
cout << \"connection resolved.\" << endl;
}
void acceptor_loop(){
boost::asio::io_service io_service;
int m_nPort = 12345;
tcp::acceptor acceptor(io_service, tcp::endpoint(tcp::v4(), m_nPort));
cout << \"Waiting for connection...\" << endl;
while(true)
{
try
{
tcp::socket socket(io_service);
acceptor.accept(socket);
cout << \"connection accepted.\" << endl;
boost::thread workerThread2(request_response_loop, socket); // here it does not compile because of C2248
}
catch(exception &e)
{
cerr << e.what() << endl; //\"The parameter is incorrect\" exception
}
}
}
int main()
{
boost::thread workerThread(acceptor_loop);
cin.get();
}
Error 1 error C2248: boost::noncopyable_::noncopyable::noncopyable: \"boost::noncopyable_::noncopyable\" boost\\asio\\basic_io_object.hpp 93

是这里的常用机制：void request_response_loop(boost::shared_ptr<tcp::socket> socket) { http_request request(*socket); http_response response; response.body = \"<head></head><body><h1>It Rocks!</h1></body>\"; response.send(*socket); socket->close(); cout << \"connection resolved.\" << endl; } void acceptor_loop() { boost::asio::io_service io_service; int m_nPort = 12345; tcp::acceptor acceptor(io_service, tcp::endpoint(tcp::v4(), m_nPort)); cout << \"Waiting for connection...\" << endl; while(true) { try { boost::shared_ptr<tcp::socket> socket = boost::make_shared<tcp::socket>(boost::ref(io_service)); acceptor.accept(*socket); cout << \"connection accepted.\" << endl; boost::thread workerThread2(request_response_loop, socket); } catch(exception &e) { cerr << e.what() << endl; } } }恋卡
函数不会等待，因此一旦超出范围，它将立即销毁套接字。 您需要对线程之间传递的变量使用动态或静态生命周期，而永远不要使用自动生命周期。
