C++11 implementation of Socket.IO client
By virtue of being written in C++, this client works in several different platforms. The examples folder contains an iPhone, QT and Console example chat client! It depends on websocket++ and is inspired by socket.io-clientpp.
| C++ Client version | Socket.IO server version | |
|---|---|---|
| 1.x / 2.x | 3.x / 4.x | |
2.x (2.x branch) |
YES | YES, with allowEIO3: true |
3.x (master branch) |
NO | YES |
Note: Only the WebSocket transport is currently implemented (no fallback to HTTP long-polling)
** Full overview of API can be seen here **
The APIs are similar to the JS client.
sio::client h;
h.connect("http://127.0.0.1:3000");// emit event name only: h.socket()->emit("login"); // emit text h.socket()->emit("add user", username); // emit binary char buf[100]; h.socket()->emit("add user", std::make_shared<std::string>(buf,100)); // emit message object with lambda ack handler h.socket()->emit("add user", string_message::create(username), [&](message::list const& msg) { }); // emit multiple arguments message::list li("sports"); li.push(string_message::create("economics")); socket->emit("categories", li);
Items in message::list will be expanded in server side event callback function as function arguments.
void OnMessage(sio::event &) { } h.socket()->on("new message", &OnMessage);
h.socket()->on("login", [&](sio::event& ev) { //handle login message //post to UI thread if any UI updating. });
class MessageHandler { public: void OnMessage(sio::event &); }; MessageHandler mh; h.socket()->on("new message",std::bind( &MessageHandler::OnMessage,&mh,std::placeholders::_1));
h.socket("/chat")->emit("add user", username);
