await multiple sendRequestCoro

[alwaysvitorious]

Hi everyone. I see there is a pull request to implement when_all. Any update on that? I was trying to implement futures with .get() and ended up blocking the client. Is anyone sending multiple requests in parallel and awaiting them all? I am looking for different options to achieve it until when_all is implemented.

drogon::Task<> send_a_request(
...
auto response = co_await http_client->sendRequestCoro(req, 60.0);
co_return ...
...
// how do i start them all concurrently ->
auto req1_result = co_await send_a_request(1);;
auto req2_result = co_await send_a_request(2);;
auto req3_result = co_await send_a_request(3);;

thanks!
