How could I receive the entire buffer?

I would like to be able to read, or receive, the entire buffer that was sent to the socket.

Currently, this is my way of receiving data from the server.

std::string Client::Receive()
{
    std::string data;
    data.resize(1024);
    m_sock.receive(boost::asio::buffer(data));
    return data;
}

Though if the server sends something larger than 1024 bytes, that won't work. I'd like to overcome this obstacle.

How could I do that?
Thanks a lot!

You can use std::stringstream.

https://ru.cppreference.com/w/cpp/io/basic_stringstream

After reading from socket you could use stringstream::str() function to get string from it.

Use an std::ostream_iterator https://en.cppreference.com/w/cpp/iterator/ostream_iterator

It's essentially a pointer that you can just keep writing to, keep in mind you need an actual stream to store it to
