小编mar*_*era的帖子

我正在尝试连接到使用SSL的Web服务.我正在使用QNX IDE Momentics在C++中使用Blackberry 10.我正在尝试的连接如下:

网址:"https:// movilapi ...."

码:

networkAccessManager = new QNetworkAccessManager(this);
    bool res = connect(networkAccessManager, SIGNAL(finished(QNetworkReply*)),
            this, SLOT(requestFinished(QNetworkReply*)));

    Q_ASSERT(res);
    Q_UNUSED(res);

    QNetworkRequest request = QNetworkRequest(QUrl(url));
    request.setRawHeader("User-Agent", "bb-phone/20120910");
    request.setRawHeader("Content-Type", "application/json");
    request.setRawHeader("Content-Length", postDataSize);

    QSslConfiguration sslConfig = request.sslConfiguration();
    sslConfig.setPeerVerifyMode(QSslSocket::VerifyNone);
    sslConfig.setProtocol(QSsl::TlsV1);
    request.setSslConfiguration(sslConfig);

        networkAccessManager->post(request, outData);

无论我试图达到哪种服务,我总是得到同样的错误.响应是: SSL握手失败

我是QML和QML信号的新手,我遇到了这个我自己无法解决的愚蠢问题.我正在触发一个onTouch信号并执行两次,产生一个双重响应,崩溃了我的应用程序.

这是我的QML代码:

//LabelKey.qml

import bb.cascades 1.0

Container {

    property string labelText: "#"
    property real width: 153.3
    property real height: 102.5
    property int labelPosX: 60
    property int labelPosY: 25
    property int labelTextFontWidth: 45
    property string imgSrc: "asset:///images/keyboard_button.png"

    layout: AbsoluteLayout {
    }
    preferredWidth: width
    preferredHeight: height
    objectName: "contTecla"
    id: contTecla
    ImageView {
        objectName: "imgTecla"
        id: imgTecla1
        imageSource: imgSrc
        preferredWidth: width
        preferredHeight: height
        onTouch: {
            textFieldKey.text = textFieldKey.text + labelTecla.text;
        }
    }
    Label {
        objectName: "labelTecla"
        id: labelTecla
        text: labelText
        textStyle …

这是任何语言中最愚蠢的事情,但我仍然坚持如何在QML中做到这一点.

如何在QML中更改Label的文本值？我错过了什么..

我的代码如下:

Container {
  objectName: "formContainer"
  id: formContainer

  property alias text1: labelTest.text

  onCreationCompleted: {
      Qt.labelTest = labelTest;
      Qt.text1 = formContainer.text1;
  }

  Label {
      id: labelTest
      text: "test"
  }

  TextField {
      id: textFieldPass
      onFocusedChanged: {
             if (focused) {
                     Qt.myFunction();
             }
      }
   }

    function myFunction(){
       //Enter successfuly to the function
       console.log("Qt.labelTest.text:" + Qt.labelTest.text);  //Output: undefined
       Qt.labelTest.text = "Y U NO change!";  //Does nothing
       Qt.text1 = "Y U NO change!";           //Does nothing  
    }
 }

我不确定为什么不工作.即使使用别名属性,文本也会拒绝更改.我将不胜感激任何帮助.

感谢致敬.
