William Lallemand 33b0d095cc MINOR: httpclient: implement a simple HTTP Client API ... This commit implements a very simple HTTP Client API. A client can be operated by several functions: - httpclient_new(), httpclient_destroy(): create and destroy the struct httpclient instance. - httpclient_req_gen(): generate a complete HTX request using the the absolute URL, the method and a list of headers. This request is complete and sets the HTX End of Message flag. This is limited to small request we don't need a body. - httpclient_start() fill a sockaddr storage with a IP extracted from the URL (it cannot resolve an fqdm for now), start the applet. It also stores the ptr of the caller which could be an appctx or something else. - hc->ops contains a list of callbacks used by the HTTPClient, they should be filled manually after an httpclient_new(): * res_stline(): the client received a start line, its content will be stored in hc->res.vsn, hc->res.status, hc->res.reason * res_headers(): the client received headers, they are stored in hc->res.hdrs. * res_payload(): the client received some payload data, they are stored in the hc->res.buf buffer and could be extracted with the httpclient_res_xfer() function, which takes a destination buffer as a parameter * res_end(): this callback is called once we finished to receive the response.		2021-08-18 17:36:32 +02:00
