Title: Asynchronous http request?

Hello, thanks for open source, I learned a lot.

There is currently a thorny problem. My program receives external input. Each input corresponds to an http request. The server response is relatively slow. Synchronous requests will cause the program io to block for 500ms. There may be other requests to process during these 500ms. Or other operations need to be performed, so I hope that the http request operation is asynchronous.

Asynchronous means that I hope that my http request function can return immediately. When the http request returns data (json will be returned after 500ms), the returned json data will be processed through the pre-registered callback.

The desired function signature is this:

void http_request(const std::string & request_url, const std::string & header, std::function<void<const rapidjson::Document>> & func) {
}

There has been some research before, but the coding power is insufficient and has not been solved. It should be implemented using coroutines + http network operations. I wonder if you can give me some guidance? grateful

ps. Pay more attention to performance and speed

那就用协程呗 https://github.com/tboox/tbox/blob/master/src/demo/coroutine/stream.c

Then use coroutine https://github.com/tboox/tbox/blob/master/src/demo/coroutine/stream.c
