Astxx: action для команды QueueStatus (+пример)

Логическое продолжение для этой статьи, команда для получения состояния очереди.

Подкатом реализация и пример использования команд QueuePause и QueueStatus, какие эвенты получаются смотрите в документации((тут или тут, вторая ссылка более полная, но на буржуйском, хотя кого это пугает? :wink:))

Пример

Пример основан на event-test.cc, что идёт вместе с astxx.

#include <astxx/manager.h>
#include <vector>
#include <string>
#include <iostream>

#include "queue_status.h"
#include "queue_pause.h"

void print_event(astxx::manager::message::event e) 
{
   //std::cout << e.format();
   std::cout << e["Paused"] << "<br/>n";
}

int main(int argc, char** argv) 
{
   std::vector<std::string> args(argv, argv + argc);

   if (args.size() != 4) 
   {
      std::cerr << "Usage: " << args[0] << " [host] [username] [secret]<br/>n";
      return 1;
   }

   try 
   {
      namespace manager = astxx::manager;
      namespace action = astxx::manager::action;

      manager::connection connection(args[1]);
      std::cout << "Connected to " << connection.name() << " v" << connection.version() << std::endl;

      boost::signals::scoped_connection c1 = connection.register_event("QueueMember", print_event);
      //boost::signals::scoped_connection c2 = connection.register_event("Queue", print_event);

      action::login login(args[2], args[3]);
      login(connection);

      action::queue_pause qpause("SIP/3008", true);
      manager::message::response resp = qpause(connection);
      std::cout << resp.format();

      action::queue_status qstatus("SIP/3008");
      resp = qstatus(connection);
      std::cout << resp.format();

      action::queue_pause qpause2("SIP/3008", false);
      resp = qpause2(connection);
      std::cout << resp.format();

      action::queue_status qstatus2("SIP/3008");
      resp = qstatus2(connection);
      std::cout << resp.format();


      for (;;) 
      {
         connection.wait_event();
         connection.pump_messages();
         connection.process_events();
      }
      return 0;
   }
   catch (const std::exception& e) 
   {
      std::cerr << "Exception: " << e.what() << std::endl;
   }
   return 1;
}

Собственно что тут происходит: * создаём подключение * регистрируем обработчик для эвента QueueMember (смотрим токи на AMI) * логинимся * ставим мембера в паузу и спрашиваем его состояние * убираем паузу и опять спрашиваем его состояние * в цикле обрабатываем приходящие эвенты
