The message class now behaves like a pair with respect to the construction of the body and headers. Additional constructors allow construction of just the body portion from a tuple, leaving the headers default constructed. Previous constructors are removed as they were a notational convenience for assembling HTTP/1 requests and responses. They are not necessary as this library aims at library writers and not end users.

Beast provides implementations of the HTTP and WebSocket protocols
|
|
built on top of Boost.Asio and other parts of boost.
|
|
|
|
Requirements:
|
|
|
|
* Boost
|
|
* C++11 or greater
|
|
* OpenSSL (optional)
|
|
|
|
Example WebSocket program:
|
|
```C++
|
|
#include <beast/to_string.hpp>
|
|
#include <beast/websocket.hpp>
|
|
#include <boost/asio.hpp>
|
|
#include <iostream>
|
|
#include <string>
|
|
|
|
int main()
|
|
{
|
|
// Normal boost::asio setup
|
|
std::string const host = "echo.websocket.org";
|
|
boost::asio::io_service ios;
|
|
boost::asio::ip::tcp::resolver r(ios);
|
|
boost::asio::ip::tcp::socket sock(ios);
|
|
boost::asio::connect(sock,
|
|
r.resolve(boost::asio::ip::tcp::resolver::query{host, "80"}));
|
|
|
|
// WebSocket connect and send message using beast
|
|
beast::websocket::stream<boost::asio::ip::tcp::socket&> ws(sock);
|
|
ws.handshake(host, "/");
|
|
ws.write(boost::asio::buffer("Hello, world!"));
|
|
|
|
// Receive WebSocket message, print and close using beast
|
|
beast::streambuf sb;
|
|
beast::websocket::opcode op;
|
|
ws.read(op, sb);
|
|
ws.close(beast::websocket::close_code::normal);
|
|
std::cout << to_string(sb.data()) << "\n";
|
|
}
|
|
```
|
|
|
|
Example HTTP program:
|
|
```C++
|
|
#include <beast/http.hpp>
|
|
#include <boost/asio.hpp>
|
|
#include <iostream>
|
|
#include <string>
|
|
|
|
int main()
|
|
{
|
|
// Normal boost::asio setup
|
|
std::string const host = "boost.org";
|
|
boost::asio::io_service ios;
|
|
boost::asio::ip::tcp::resolver r(ios);
|
|
boost::asio::ip::tcp::socket sock(ios);
|
|
boost::asio::connect(sock,
|
|
r.resolve(boost::asio::ip::tcp::resolver::query{host, "http"}));
|
|
|
|
// Send HTTP request using beast
|
|
beast::http::request_v1<beast::http::empty_body> req;
|
|
req.method = "GET";
|
|
req.url = "/";
|
|
req.version = 11;
|
|
req.headers.replace("Host", host + ":" + std::to_string(sock.remote_endpoint().port()));
|
|
req.headers.replace("User-Agent", "Beast");
|
|
beast::http::prepare(req);
|
|
beast::http::write(sock, req);
|
|
|
|
// Receive and print HTTP response using beast
|
|
beast::streambuf sb;
|
|
beast::http::response_v1<beast::http::streambuf_body> resp;
|
|
beast::http::read(sock, sb, resp);
|
|
std::cout << resp;
|
|
}
|
|
```
