Question

因此，我尝试遵循此教程： https://www.c-sharpcorner.com/article/socket-programming-in-cpp-using-boost-asio-tcp-server-and-client/

但是我在第4行using ip::tcp上遇到错误，错误是“标识符ip未定义”

我将Visual Studio 2019与WSL一起使用，我做了一些挖掘工作，并且在我的boost / asio / ip / tcp.hpp文件中也存在一些错误。在typedef basic_endpoint<tcp> endpoint;行上，出现错误，指出basic_endpoint不是模板。

希望你们能有所帮助。

#include <iostream>  
#include <boost/asio.hpp>

using namespace boost::asio;
using ip::tcp;
using std::string;
using std::cout;
using std::endl;

string read_(tcp::socket& socket) {
    boost::asio::streambuf buf;
    boost::asio::read_until(socket, buf, "\n");
    string data = boost::asio::buffer_cast<const char*>(buf.data());
    return data;
}

void send_(tcp::socket& socket, const string& message) {
    const string msg = message + "\n";
    boost::asio::write(socket, boost::asio::buffer(message));
}

int main() {
    boost::asio::io_service io_service;

    //listen for new connection  
    tcp::acceptor acceptor_(io_service, tcp::endpoint(tcp::v4(), 1234));

    //socket creation  
    tcp::socket socket_(io_service);

    //waiting for the connection  
    acceptor_.accept(socket_);

    //read operation  
    string message = read_(socket_);
    cout << message << endl;

    //write operation  
    send_(socket_, "Hello From Server!");
    cout << "Servent sent Hello message to Client!" << endl;
    return 0;
}

为什么会出现“标识符IP未定义”错误？使用boost :: asio
