How to send json-file to the address?
-
I took the example code, and it says so:
SslEchoClient::SslEchoClient(const QUrl &url, QObject *parent) : QObject(parent) { connect(&m_webSocket, &QWebSocket::connected, this, &SslEchoClient::onConnected); connect(&m_webSocket, QOverload<const QList<QSslError>&>::of(&QWebSocket::sslErrors), this, &SslEchoClient::onSslErrors); m_webSocket.open(QUrl(url)); }There are signals and slots, I create an object of this class, but it does not connect. Why?
@Mikeeeeee said in How to send json-file to the address?:
QWebSocket::sslErrors
why the overload ? as far as I can see
sslErrorshas no alternatives to QList<QSslErrors> -
Tried to start an example "SslEchoClient", but it irzhe does not connect and does not display error messages.
In my project I connected the status output to the button:#include "mainwindow.h" #include "ui_mainwindow.h" MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow) { ui->setupUi(this); myUrl = "wss://ws.binaryws.com/websockets/v3?app_id=xlY2chJRk0XoSL5"; myWebSocket.open(QUrl(myUrl)); qDebug()<<myWebSocket.isValid()<<myWebSocket.state(); } MainWindow::~MainWindow() { delete ui; } void MainWindow::on_testButton_clicked() { qDebug()<<myWebSocket.isValid()<<myWebSocket.state()<<myWebSocket.error(); }Debug return:
false QAbstractSocket::UnconnectedState QAbstractSocket::UnknownSocketError
false QAbstractSocket::UnconnectedState QAbstractSocket::UnknownSocketError
false QAbstractSocket::UnconnectedState QAbstractSocket::UnknownSocketError
false QAbstractSocket::UnconnectedState QAbstractSocket::UnknownSocketErrorWhy can't I even use the example "SslEchoClient" to connect to the websocket?

@Mikeeeeee DO YOU HAVE ANY ERRORS WHEN TRYING TO CONNECT? After calling myWebSocket.open(QUrl(myUrl).
Did you connect a slot to https://doc.qt.io/qt-5/qwebsocket.html#error-1 as I suggested?
Is your onSslErrors called? -
I did, but debag doesn't say it was a error:
myUrl = "wss://ws.binaryws.com/websockets/v3?app_id=xlY2chJRk0XoSL5"; myWebSocket.open(QUrl(myUrl)); //myWebSocket qDebug()<<myWebSocket.isValid()<<myWebSocket.state(); connect(&myWebSocket, QOverload<QAbstractSocket::SocketError>::of(&QWebSocket::error), [=](QAbstractSocket::SocketError error){ qDebug()<<"i have error";});Example "SslEchoClient" also no message, means no error, but the websocket is not connected.

If I use the program with GitHub, I get an error: "WebSocket::processHandshake: Unhandled http status code 301"
Please tell me why and how to fix it?@Mikeeeeee If you use Google to search for "http 301" you will find https://en.wikipedia.org/wiki/HTTP_301 which tells you that 301 status code means "Moved Permanently is used for permanent URL redirection". What URL are you using?
