查看qt支持的ssl版本和当前支持的网络协议

复制代码

1. //查看当前网络请求支持协议
       
     QStringList zhi=manger->supportedSchemes();
   QString str = zhi.join(" "); // 将各段用":"连接形成新的字符串
            QMessageBox msgBox;
       msgBox.setText("当前手机支持协议:\n"+str);
       msgBox.exec();

    

复制代码

1. // 发送https请求前准备工作;
              network_request->setUrl(QUrl(ui->lineEdit->text()));
       QSslConfiguration conf = network_request->sslConfiguration();
       conf.setPeerVerifyMode(QSslSocket::VerifyNone);
       conf.setProtocol(QSsl::TlsV1SslV3);
       network_request->setSslConfiguration(conf);
   //    network_request->setAttribute(QNetworkRequest::HttpPipeliningAllowedAttribute, true);
     
   
             QNetworkReply *reply =network_manager->get(*network_request);
               QString ssl=QSslSocket::sslLibraryBuildVersionString();
      //QString str = ssl.join(" "); // 将各段用":"连接形成新的字符串
            QMessageBox msgBox;
       msgBox.setText("openssl版本信息:\n"+ssl);
       msgBox.exec();

查看 qt 支持的 ssl 版本和当前支持的网络协议(备用)
    // 查詢Qt支持的版本
bool bSupp = QSslSocket::supportsSsl();
QString buildVersion = QSslSocket::sslLibraryBuildVersionString();QString version = QSslSocket::sslLibraryVersionString();
qDebug() << bSupp << buildVersion << version;
// 查看当前网络请求支持协议
QNetworkAccessManager *accessManager = new QNetworkAccessManager(this);qDebug() << accessManager->supportedSchemes();

SSL 证书认证三种方式
  SSL 证书认证，有以下三种：
// 1. 方法
QSslConfiguration config ;
config.setPeerVerifyMode(QSslSocket::VerifyNone);
config.setProtocol(QSsl::TlsV1);
QNetworkRequest request(req);
request.setSslConfiguration(config);
// 2. 方法
QNetworkRequest request ;
request.setAttribute(QNetworkRequest::HttpPipeliningAllowedAttribute, true);
QNetworkReply* reply = QNetworkAccessManager::createRequest(op, request, outgoingData);reply->ignoreSslErrors();
// 3. 方法
QSslConfiguration config ;
QList<QSslCertificate> certs = QSslCertificate::fromPath("C:\\FiddlerRoot.crt");
config.setCaCertificates(certs);
QNetworkRequest request(req);
request.setSslConfiguration(config);
