Question

我试图通过使用C ++来连接echo.websocket.org来使用安全的websocket。它适用于 https://www.websocket.org/echo.html

的javascript

我的解决方案是使用Poco库，我的代码如下所示。

Poco::Net::initializeSSL();

Poco::Net::Context context(Poco::Net::Context::CLIENT_USE, "", "", "", Poco::Net::Context::VERIFY_RELAXED, 9, false, "ALL:!ADH:!LOW:!EXP:!MD5:@STRENGTH");

Poco::Net::HTTPSClientSession Client("echo.websocket.org", 443, &context);

Poco::Net::HTTPRequest request(Poco::Net::HTTPRequest::HTTP_GET, "/?encoding=text", Poco::Net::HTTPMessage::HTTP_1_1);
request.set("origin", "https://www.websocket.org");
Poco::Net::HTTPResponse response;

try
{
    Poco::Net::WebSocket webSocket(Client, request, response);

    std::string str = "Hello!";

    char receiveBuff[256];

    int len = webSocket.sendFrame(str.data(), str.size(), Poco::Net::WebSocket::FRAME_TEXT);
    std::cout << "Sent bytes " << len << std::endl;
    int flags = 0;

    int rlen = webSocket.receiveFrame(receiveBuff, 256, flags);
    std::cout << "Received bytes " << rlen << std::endl;
    std::cout << receiveBuff << std::endl;

    webSocket.close();
}
catch (std::exception &e)
{
    std::cout << "Exception " << e.what();
}

但我使用此代码获得SSL Exception。请问有人帮帮我吗？感谢
