c++ - Microsoft C++ 异常:内存位置的 boost::archive::archive_exception(通过客户端服务器 Boost Udp 解析 vector )

Question

exception: boost::archive::archive_exception at memory location

我发现了这个但没有用，因为他正在为文件做而我只想为 vector 做。

问题:我在服务器端对 vector 进行了序列化，然后解析到客户端，然后我在那里进行反序列化。所以 1/2 记录一切正常。

但是如果我插入超过 2 条记录并通过 vector 解析它，它会在我反序列化数据的客户端给我这个错误:Microsoft C++ 异常:内存位置的 boost::archive::archive_exception

这是我的代码:

服务器端:

通过将 Vector 作为输入来序列化数据

//I think these headers are enough !!!

#include <boost/archive/text_iarchive.hpp>
#include <boost/archive/text_oarchive.hpp>
#include<boost/serialization/vector.hpp>
#include<boost/serialization/map.hpp>

template<class input>
void UdpServer::serializeData(input &vector) { // Here i use vector in parameter
    std::ostringstream archive_stream;
    boost::archive::text_oarchive archive(archive_stream);
    archive << vector;
    sendMessageToClients(archive_stream.str());//sending to client
}

我收到错误的客户端，

#include <boost/archive/text_iarchive.hpp>
#include <boost/archive/text_oarchive.hpp>
#include<boost/serialization/vector.hpp>
#include<boost/serialization/map.hpp>

//this is what i received from the server
size_t const len = m_socket.receive_from(
        boost::asio::buffer(recv_buf), m_sender_endpoint);

    std::string const received_message(recv_buf.data(), len);

std::string archive_data(received_message);// receive from server
        std::istringstream archive_stream(archive_data);
        boost::archive::text_iarchive archive(archive_stream);
        archive >> map;
        displayCarData(map); //i'm passing this to function for printing the values   

我尝试添加 Boost io 二进制库，但错误是: C++超出范围的内存位置 //这是我使用 io 二进制库的尝试

 std::string archive_data(received_message);
            std::istringstream archive_stream(archive_data);
            boost::archive::text_iarchive archive(archive_stream, boost::io::binary);
            archive >> map;
            displayCarData(map);

如有任何帮助，我们将不胜感激

提前致谢

//this is what i received from the server
size_t const len = m_socket.receive_from(
    boost::asio::buffer(recv_buf,1024), m_sender_endpoint);

我想你必须给出尺寸

 boost::asio::buffer(recv_buf,1024), m_sender_endpoint);

在这一行中，也适用于服务器端。
