在C++中,有几个流行的WebSocket库可以用于实现WebSocket客户端和服务器
websocketpp
库:websocketpp
是一个高性能的C++ WebSocket库,支持Boost.Asio库。要实现自动重连,你需要在连接断开时捕获相应的事件,并在适当的时候尝试重新连接。
首先,安装websocketpp
库:
git clone https://github.com/zaphoyd/websocketpp.git
cd websocketpp
mkdir build
cd build
cmake ..
make install
然后,创建一个名为websocket_client.cpp
的文件,包含以下内容:
#include<iostream>
#include <websocketpp/config/asio_no_tls_client.hpp>
#include <websocketpp/client.hpp>
typedef websocketpp::client<websocketpp::config::asio_client> client;
using websocketpp::lib::placeholders::_1;
using websocketpp::lib::placeholders::_2;
using websocketpp::lib::bind;
class WebSocketClient {
public:
WebSocketClient() : m_reconnecting(false) {
m_client.clear_access_channels(websocketpp::log::alevel::all);
m_client.clear_error_channels(websocketpp::log::elevel::all);
m_client.init_asio();
m_client.set_open_handler(bind(&WebSocketClient::on_open, this, _1));
m_client.set_close_handler(bind(&WebSocketClient::on_close, this, _1));
m_client.set_fail_handler(bind(&WebSocketClient::on_fail, this, _1));
}
void connect(const std::string &uri) {
websocketpp::lib::error_code ec;
client::connection_ptr con = m_client.get_connection(uri, ec);
if (ec) {
std::cout << "Could not create connection: " << ec.message()<< std::endl;
return;
}
m_client.connect(con);
}
void run() {
m_client.run();
}
private:
void on_open(websocketpp::connection_hdl hdl) {
std::cout << "Connected to server"<< std::endl;
m_reconnecting = false;
}
void on_close(websocketpp::connection_hdl hdl) {
std::cout << "Connection closed"<< std::endl;
if (!m_reconnecting) {
m_reconnecting = true;
m_client.get_io_service().post(bind(&WebSocketClient::reconnect, this));
}
}
void on_fail(websocketpp::connection_hdl hdl) {
std::cout << "Connection failed"<< std::endl;
if (!m_reconnecting) {
m_reconnecting = true;
m_client.get_io_service().post(bind(&WebSocketClient::reconnect, this));
}
}
void reconnect() {
std::cout << "Reconnecting..."<< std::endl;
connect("ws://your-websocket-server-uri");
}
client m_client;
bool m_reconnecting;
};
int main() {
WebSocketClient client;
client.connect("ws://your-websocket-server-uri");
client.run();
return 0;
}
编译并运行示例:
g++ websocket_client.cpp -o websocket_client -lwebsocketpp -lpthread -lboost_system
./websocket_client
这个示例将连接到指定的WebSocket服务器,并在连接断开时尝试自动重连。请确保将your-websocket-server-uri
替换为实际的WebSocket服务器URI。
