about HTTP request crashes bug

[zzl-010]

#383
hello all:

     now have a bug of HTTP get request crashes.
     when request style is: GET /%NETHOOD%/ HTTP/1.1

     I used one curl command test found crashes caused by the GET /%NETHOOD%/
     follow the demo:
            curl -w'\n' -v -X GET '127.0.0.1:9086/%NETHOOD%/'
     The program crashes after the curl request，and When I debugged with GDB, I found it in a source file of method：restbed::Uri::decode()
     I'd like you to take care of this problem and hopefully handle the % symbol and decoding in HTTP requests in a friendly way
     Thanks to everyone！

the example code :
void get_method_handler( const shared_ptr< Session > session )
{
session->close( 200,"hello " );
}
int main( const int, const char** )
{
auto resource = make_shared< Resource >( );
resource->set_path( "/resource" );
resource->set_method_handler( "GET", get_method_handler );
auto settings = make_shared< Settings >( );
settings->set_port( 9086);
settings->set_default_header( "Connection", "close" );
Service service;
service.publish( resource );
service.start( settings );
return EXIT_SUCCESS;
}
