AWebsocket

WebSocket client (ws:// and wss://) built on top of ACurl.

Header:	#include <AUI/Curl/AWebsocket.h>
CMake:	aui_link(my_target PUBLIC aui::curl)

Detailed Description

Connects on run(). Connection, incoming messages and closing are reported with signals; outgoing messages are sent with writeText and writeBinary (or by using AWebsocket as an IOutputStream, which sends text frames).

auto ws = _new<AWebsocket>("wss://ws.postman-echo.com/raw");
AObject::connect(ws->connected, ws, [&] { ws->writeText("hello"); });
AObject::connect(ws->received, ws, [&](AByteBufferView data) {
    ALogger::info("ws") << AString::fromUtf8(data);
    ws->close();
});
ws->run(); // blocks until closed

run() blocks the calling thread, so use a dedicated thread (or an AThreadPool task) when the UI thread must stay responsive. Signals are emitted on the thread that runs the connection.
