Qt QNetworkReply连接已关闭

Question

我尝试在c++中对url https://...执行post方法，但收到连接关闭错误。

我发现，如果我使用另一个url，比如https://www.google.gr，我的代码就能正常工作。

如果我删除端口8181，我会得到错误：server replied:not found。

我的代码是

static const char *REQUEST_URL="https://...";
static const char *USER = "....";
static const char *PASSWORD = "....";

MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
    ui->setupUi(this);
    finishedexecuted=0;
    QByteArray postData;
    postData.append("username=...");
    postData.append("password= ...");
    m_network = new QNetworkAccessManager(this);
    QNetworkRequest request;
    request.setHeader(QNetworkRequest::ContentTypeHeader, "application/json");
    QUrl url=QUrl(REQUEST_URL);
    request.setUrl(url);
    QSslConfiguration config = request.sslConfiguration();        
    QList<QSslCertificate> certs = 
                          QSslCertificate::fromPath("pistopoiitiko.crt");
    config.setCaCertificates(certs);        
    request.setSslConfiguration(config);
    QNetworkReply *reply = m_network->post(request,postData);

    downloadTime.start();
    QObject::connect(reply, SIGNAL(downloadProgress(qint64,qint64)),
                     SLOT(slotSetProgress(qint64,qint64)));
    QObject::connect(m_network, SIGNAL(finished(QNetworkReply *)),
                     SLOT(slotRequestFinished(QNetworkReply *)));

    connect(m_network, 
            SIGNAL(sslErrors(QNetworkReply *, const QList<QSslError> &)),
            this, 
            SLOT(sslError(QNetworkReply*, const QList<QSslError> &)));
    } 

void MainWindow::sslError(QNetworkReply* reply, 
                           const QList<QSslError> &errors )
{...}

void MainWindow::slotRequestFinished(QNetworkReply *reply)
{
 ...
    if (reply->error() > 0) {
    m_label->setText("Error number = " + reply->errorString());
   }
 ...
}

void MainWindow::slotSetProgress(qint64 received, qint64 total)
{...}

有什么想法吗？

Answer 1

我用这段代码克服了这个问题。

QSslConfiguration config = QSslConfiguration::defaultConfiguration();
config.setProtocol(QSsl::SslV3);

然后，我收到了ssl错误，这些错误是我传递的，并带有ignoresslerrors()
