【中文标题】Websocket++ 错误：handle_transport_init 收到错误：TLS 握手失败

【英文标题】：Websocket++ error: handle_transport_init received error: TLS handshake failed

【发布时间】：2020-07-02 19:29:08

【问题描述】：

当我连接到本地主机时，它工作了。但是当我尝试连接到 wss://echo.websocket.org 时，它会说：

[2020-07-03 00:24:19] [connect] 连接成功

[2020-07-03 00:24:20] [error] handle_transport_init 收到错误：TLS 握手失败

[2020-07-03 00:24:20] [失败] WebSocket 连接 174.129.224.73:443 - "" / 0 websocketpp.transport.asio.socket:8 TLS 握手失败

[2020-07-03 00:24:20] [info] asio async_shutdown 错误：asio.ssl:336462231（在初始化时关闭）

我需要做什么才能让它工作？

部分代码：

typedef websocketpp::client<websocketpp::config::asio_tls_client> client;

struct connection_data

    bool status;
    string error;
    
    vector <string> messages;

    client::connection_ptr con;
    websocketpp::lib::shared_ptr<websocketpp::lib::thread> m_thread;
;

struct connection_data m_con;
client cl;

using namespace std;
using websocketpp::lib::placeholders::_1;
using websocketpp::lib::placeholders::_2;
using websocketpp::lib::bind;

typedef websocketpp::config::asio_client::message_type::ptr message_ptr;
typedef websocketpp::lib::shared_ptr<websocketpp::lib::asio::ssl::context> context_ptr; 

void on_message(client* c, websocketpp::connection_hdl hdl, message_ptr msg)

    m_con.messages.push_back(msg->get_payload());


void on_open(client* c, websocketpp::connection_hdl hdl)

    m_con.status = true;


void on_close(client* c, websocketpp::connection_hdl hdl)

    m_con.status = false;
    m_con.con = c->get_con_from_hdl(hdl);
    m_con.messages.clear();
    m_con.error.clear();


context_ptr on_tls_init(const char* hostname, websocketpp::connection_hdl) 
    context_ptr ctx = websocketpp::lib::make_shared<boost::asio::ssl::context>(boost::asio::ssl::context::tlsv13);
    return ctx;


void on_http(client* c, websocketpp::http_handler hdl)

    


void run()

    cout << "Thread enter" << endl;
    cl.run();


DLL void websock_open(char* address)

    string uri = string(address);
    websocketpp::lib::error_code ec;
    try 
        cl.set_access_channels(websocketpp::log::alevel::all);
        cl.clear_access_channels(websocketpp::log::alevel::all);
        
        cl.init_asio();

        // Setting callbacks
        cl.set_message_handler(bind(&on_message, &cl, ::_1, ::_2));
        cl.set_open_handler(bind(&on_open, &cl, ::_1));
        cl.set_close_handler(bind(&on_close, &cl, ::_1));
        cl.set_tls_init_handler(bind(&on_tls_init, string(address).c_str(), ::_1));
        
        m_con.con = cl.get_connection(uri, ec);
        if (ec) 
            m_con.error = "Can't connect: " + ec.message();
        
        cl.connect(m_con.con);
        cout << "connected" << endl;
        m_con.m_thread = websocketpp::lib::make_shared<websocketpp::lib::thread>(&run);
        cout << "Thread created" << endl;
        m_con.status = true;
     catch (websocketpp::exception const & e) 
        cout << e.what() << endl;
    

【参考方案1】：

我解决了这个问题。验证证书时出错。 修复它的代码：

context_ptr on_tls_init(const char* hostname, websocketpp::connection_hdl) 
    context_ptr ctx = websocketpp::lib::make_shared<boost::asio::ssl::context>(boost::asio::ssl::context::tlsv12);
    try 
        ctx->set_options(boost::asio::ssl::context::default_workarounds |
                         boost::asio::ssl::context::no_sslv2 |
                         boost::asio::ssl::context::no_sslv3 |
                         boost::asio::ssl::context::single_dh_use);


        ctx->set_verify_mode(boost::asio::ssl::verify_none);
     catch (std::exception& e) 
        m_con.error = string(e.what());
    
    return ctx;
