如何使用cpprestsdk设置websocket SSL连接？

#include <cpprest/ws_client.h>
#include <cpprest/http_client.h>
#include <cpprest/filestream.h>
#include <iostream>

using namespace web;
using namespace web::websockets;
using namespace web::http;
using namespace concurrency::streams;

int main(int argc, char* argv[])
{
    // 初始化 SSL 上下文
    utility::string_t ssl_cert = U("path_to_your_ssl_certificate.pem");
    utility::string_t ssl_key = U("path_to_your_ssl_private_key.pem");

    http_client_config config;
    config.set_validate_certificates(true);
    config.set_ssl_context(ssl_context::create_client(ssl_cert, ssl_key));

    // 创建 WebSocket 客户端
    uri_builder builder(U("wss://your_server_address"));
    websockets::client::websocket_client client(builder.to_uri(), config);

    // 连接成功回调
    client.set_message_handler([](const websocket_incoming_message& msg)
    {
        ucout() << "Received message: " << msg.extract_string().get() << std::endl;
    });

    // 连接失败回调
    client.set_close_handler([](const websocket_close_status& status, const utility::string_t& reason)
    {
        ucout() << "Connection closed: " << status << " - " << reason << std::endl;
    });

    // 连接到 WebSocket 服务器
    client.connect().then([&client]()
    {
        ucout() << "Connected to WebSocket server" << std::endl;
        return client.send(websocket_outgoing_message(U("Hello, WebSocket!")));
    }).then([&client]()
    {
        ucout() << "Message sent" << std::endl;
        return client.close(websocket_close_status::normal_closure, U("Goodbye!")).then([&client]()
        {
            ucout() << "Connection closed" << std::endl;
        });
    }).wait();

    return 0;
}
