Question

我正在尝试使用websocket库在C ++中实现poco客户端。

根据我的理解，首先是创建到目标服务器的套接字连接，并发送http请求和升级连接到websocket。

在poco库中，Poco::Net:::HTTPClientSession有方法：

setProxy
setProxyCredentials
setProxyHost
setProxyPort

等

我使用这些方法来渗透代理，相对于客户端控制台，它显示它已连接并将请求发送到服务器，而在服务器控制台没有收到任何信息。当我从客户端捕获数据包跟踪时，观察到与代理服务器而不是目标服务器建立的连接。

Git hub项目https://github.com/hannon235/socket.io-poco/tree/master/socket.io-poco

提供的示例代码

小队（清除操作系统）代理正在使用中。

我在论坛中阅读代理设置需要更改或openssl / https需要使用。当我尝试使用安全连接时，数据包跟踪显示与目标服务器建立的连接但消息未到达服务器。我不确定连接消息的安全性如何发送到服务器。

我想知道websocket如何与代理安全连接。

示例代码如下。

int main()
{
    //create a c++ Poco logger to use and set its channel to the windows console
    //this is the same logger instance that the library will hook into
    Logger *logger = &(Logger::get("SIOClientLog"));
    logger->setChannel(new WindowsConsoleChannel());

    //Establish the socket.io connection
    //JS: var socket = io.connect("localhost:3000")
    //SIOClient *sio = SIOClient::connect("https://myserver:8004"); this also not working
    SIOClient *sio = SIOClient::connect("http://myserver:8004");

    //Create a target and register object its method onUpdate for the Update event
    TestTarget *target = new TestTarget();
    sio->on("Update", target, callback(&TestTarget::onUpdate));

    //setup is now complete, messages and events can be send and received
    logger->information("sio setup complete\n");

    logger->information("emitting test event\n");

    sio->emit("hello", "[{\"name\":\"myname\",\"type\":\"mytype\"}]");

    //wait for user input to move to next section of code
    //socket receiving occurs in another thread and will not be halted
    logger->information("Press ENTER to continue...");
    std::cin.get();

    //disconnecting the default socket with no endpoint will also disconnect all endpoints
    sio->disconnect();

    logger->information("Press ENTER to quit...");
    std::cin.get();

    return 0;
}

修改握手功能如下：

bool SIOClientImpl::handshake() {
    UInt16 aport = _port;

    _session = new HTTPClientSession(_host, aport);
    _session->setProxy("192.168.60.2",8080);
    _session->setProxyCredentials("user1","user1");
    _session->setKeepAlive(TRUE);

    HTTPRequest req(HTTPRequest::HTTP_GET,"/socket.io/1",HTTPMessage::HTTP_1_1);
    req.setKeepAlive(TRUE);

    HTTPResponse res;

    try {
        _session->sendRequest(req);
    } catch (std::exception &e) {
        return false;
    }

    std::istream& rs = _session->receiveResponse(res);
    std::cout << res.getStatus() << " " << res.getReason() << std::endl;

    ....
}

带代理的websocket无法正常工作
