QT解析嵌套JSON表达式

QT5开发环境集成了解析JSON表达式的库。使用很方便。

友情提示一下，好像在QT4环境里。须要到官网下载相关的库文件才干使用解析功能。话不多说，上代码

1、在pro文件里增加

QT += script

#include <QtScript/QScriptEngine>

比如须要解析的JSON表达式为：

解析代码为：

void MainWindow::replyFinished(QNetworkReply * reply)
{
    QByteArray data = reply->readAll();
    QString str(data);
    QMessageBox::information(this, "reslut", str);

    QScriptEngine engine;
    QScriptValue sc = engine.evaluate("value=" + str);

    if(sc.property("errorCode").toString()!= "0")
    {
        QMessageBox::information(this, "错误", "查询出现错误，请又一次查询！");
        return ;
    }

    //外层JSOM表达式，翻译结果
    this->ui->outEdit->setText(sc.property("translation").toString());

    //第二层JSON表达式。网络延伸
    QScriptValue subsc = sc.property("web");
    QScriptValue subsc1 = subsc.property(0);
    QScriptValue subsc2 = subsc.property(1);
    QScriptValue subsc3 = subsc.property(2);
    this->ui->extendEdit->setText(subsc1.property("key").toString()+":");
    this->ui->extendEdit->append(subsc1.property("value").toString());
    this->ui->extendEdit->append(subsc2.property("key").toString()+":");
    this->ui->extendEdit->append(subsc2.property("value").toString());
    this->ui->extendEdit->append(subsc3.property("key").toString()+":");
    this->ui->extendEdit->append(subsc3.property("value").toString());
}
