RapidJson与QtJson解析器互操作示例

1、JSON内容

{
   
    "ClassName": "高三",
    "Grade": "3",
    "Student": [
        {
   
            "Name": "张三",
            "ID": "001",
            "Province": "内蒙古"
        },
        {
   
            "Name": "李四",
            "ID": "002",
            "Province": "浙江"
        },
        {
   
            "Name": "王五",
            "ID": "003",
            "Province": "江苏"
        }
    ],
    "Subject": [
        "Mathematic",
        "Physics",
        "Biology",
        "Chemical",
        "Gymnastic"
    ]
}

2、解析代码

#include <QCoreApplication>
#include <QDebug>
#include <string>

#include <QJsonDocument>
#include <QJsonObject>
#include <QJsonArray>
#include <QJsonValue>

#include "rapidjson/document.h"
#include "rapidjson/stringbuffer.h"
#include "rapidjson/prettywriter.h"

/********************************************************
 *
 *              1. 创建QtJson，返回std::string
 *
 * ******************************************************/
std::string MakeQtJson()
{
   
    /* 构建Json数组 */
    QJsonArray subject;
    subject.append("Mathematic");
    subject.append("Physics");
    subject.append("Biology");
    subject.append("Chemical");
    subject.append("Gymnastic");

    /* 构建Json对象 */
    QJsonObject zs;
    zs.insert("ID","001");
    zs.insert("Name",QStringLiteral("张三"));
    zs.insert("Province",QStringLiteral("内蒙古"));

    QJsonObject ls;
    ls.insert("ID","002");
    ls.insert("Name",QStringLiteral("李四"));
    ls.insert("Province",QStringLiteral("浙江"));

    QJsonObject ww;
    ww.insert("ID","003");
    ww.insert("Name",QStringLiteral("王五"));
    ww.insert("Province",QStringLiteral("江苏"));

    /* 构建嵌套Json数组 */
    QJsonArray student;
    student.append(QJsonValue(zx))
