Overview
--------
The HTTP client functionality is DEPRECATED and will be removed from future releases. See [Restless](https://github.com/Corvusoft/restless) for an alternative implementation.
Example
-------
```C++
#include <memory>
#include <future>
#include <cstdio>
#include <cstdlib>
#include <restbed>
using namespace std;
using namespace restbed;
void print( const shared_ptr< Response >& response )
{
fprintf( stderr, "*** Response ***\n" );
fprintf( stderr, "Status Code: %i\n", response->get_status_code( ) );
fprintf( stderr, "Status Message: %s\n", response->get_status_message( ).data( ) );
fprintf( stderr, "HTTP Version: %.1f\n", response->get_version( ) );
fprintf( stderr, "HTTP Protocol: %s\n", response->get_protocol( ).data( ) );
for ( const auto header : response->get_headers( ) )
{
fprintf( stderr, "Header '%s' > '%s'\n", header.first.data( ), header.second.data( ) );
}
auto length = response->get_header( "Content-Length", 0 );
Http::fetch( length, response );
fprintf( stderr, "Body: %.*s...\n\n", 25, response->get_body( ).data( ) );
}
int main( const int, const char** )
{
auto request = make_shared< Request >( Uri( "http://www.corvusoft.co.uk:80/?query=search%20term" ) );
request->set_header( "Accept", "*/*" );
request->set_header( "Host", "www.corvusoft.co.uk" );
auto response = Http::sync( request );
print( response );
auto future = Http::async( request, [ ]( const shared_ptr< Request >, const shared_ptr< Response > response )
{
fprintf( stderr, "Printing async response\n" );
print( response );
} );
future.wait( );
return EXIT_SUCCESS;
}
```
