[Cppcms-users] socket communication example

[adi.fatol <adi...@ar...>]

Hello all,

I am a PHP developer and I want make a few tests using the cppcms 
framework. I know C/C++ but I have little experience using it.
I use an "echo server" written in PHP, you can find it here: 
http://php.net/manual/en/sockets.examples.php.
I want to send a message to the server. For this I use this function I 
have implemented:

     void send_msg(const char *msg) {

         booster::aio::stream_socket socket_;
         booster::system::error_code err;
         int w_bytes, r_bytes;

         booster::aio::endpoint ep("127.0.0.1", 10000);

         std::cout << "connecting..." << std::endl;

         socket_.open(booster::aio::family_type::pf_inet, err);
         std::cout << "open error: " << err.value() << std::endl;

         socket_.connect(ep, err);
         std::cout << "connection error: " << err.value() << std::endl;

         try {
             w_bytes = socket_.write(booster::aio::buffer(msg, 
sizeof(msg)), err);
             std::cout << "written bytes: " << w_bytes << std::endl;

         } catch (booster::system::system_error write_err) {
             std::cout << "Exception raised: " << write_err.code() << '\n';
         }

socket_.shutdown(booster::aio::stream_socket::how_type::shut_rdwr);

         socket_.close();
     }

I get no error on socket connect, but the problem is that I always get 
returned that 4 bytes were written and the php server crashes with the 
error: "Connection reset by peer".
The server works ok in other instances, as I am able to connect to it 
using telnet and I get the messages echoed.
I think the issue is that I don't understand very well how to use the 
sockets from booster library and I would kindly ask you for an link 
where I can see a simple example or if you can provide some tips. Also, 
I have looked at the echo_server example but it's quite complicated and 
I want to test a simple client initially.

Thank you,
