Name

Asio HTTP Clients Pool.

Description

HTTP clients pool for bulk requests in asynchronous mode. This code is part of the TMS software.

Usage

• Simple example

  // declare asio thread pool and client http pool
  using namespace tms;
  static boost::asio::thread_pool io(4);
  static http_client_pool pool(io.get_executor(), 4);
  
  // process http get request
  pool.enqueue<http_string_body>("exemple.com", "80", "/test", nullopt, [](http_error err, http_stage stage, http_string_response&& resp){
      std::cout << "http ";
      if (stage >= http_stage_read) {
          std::cout << resp.result_int() << " " << resp.reason();
      }
      if (err) {
          std::cout << " error[" << err << "] " << err.message();
      }
      std::cout << " body[len: " << resp.body().size() << "]"
  });
      

Additional

• Simple asynchronous timer with loop mode
• Universal URI parser template for char/wchar_t and std::string/std:string_view/boost::string_view

  uri_t<wchar_t> uri;
  
  // parse and apply only submitted parts
  uri.parse(L"///test?params");
  uri.parse(L"guest:demo@exemple.com");
  uri.parse(L"https:///temp");
  
  // ignore arguments, but apply 443 port by https prefix
  uri.set_defaults(L"http", L"localhost"); 
  
  // check result
  if (uri.str() != L"https://guest:demo@exemple.com:443/temp?params") {
      throw std::runtime_error("uri parse/split algoritms failed");
  };
