如果给你一组json数据，需要将它的所有变量声明为一个结构体，也许简单的json数据你能做到，也很乐意做，但你给一组复杂的json数据就不知如何着手做了。为了解决这个痛点，我开发了这款软件，可以将一组json数据转化为结构体定义，同时，还可以转换为解析json的Qt代码，帮助你省去解析json的时间，非常高效。nice!

效果如下：
图1转为结构体

图2转为解析json代码

json数据

复制代码

{
"code": "200",
"updateTime": "2020-06-30T22:00+08:00",
"fxLink": "http://hfx.link/2ax1",
"now": {
"obsTime": "2020-06-30T21:40+08:00",
"temp": "24",
"feelsLike": "26",
"icon": "101",
"text": "??",
"wind360": "123",
"windDir": "???",
"windScale": "1",
"windSpeed": "3",
"humidity": "72",
"precip": "0.0",
"pressure": "1003",
"vis": "16",
"cloud": "10",
"dew": "21"
},
"refer": {
"sources": [
"QWeather",
"NMC",
"ECMWF"
],
"license": [
"commercial license"
]
}
}

生成结构体代码

复制代码

struct Now
{
QString cloud;
QString dew;
QString feelsLike;
QString humidity;
QString icon;
QString obsTime;
QString precip;
QString pressure;
QString temp;
QString text;
QString vis;
QString wind360;
QString windDir;
QString windScale;
QString windSpeed;
Now()
{
cloud = "10";
dew = "21";
feelsLike = "26";
humidity = "72";
icon = "101";
obsTime = "2020-06-30T21:40+08:00";
precip = "0.0";
pressure = "1003";
temp = "24";
text = "??";
vis = "16";
wind360 = "123";
windDir = "???";
windScale = "1";
windSpeed = "3";
}
};
struct Refer
{
QStringList license;
QStringList sources;
Refer()
{
license << "commercial license";
sources << "QWeather";
sources << "NMC";
sources << "ECMWF";
}
};
struct Undefined
{
QString code;
QString fxLink;
Now now;
Refer refer;
QString updateTime;
Undefined()
{
code = "200";
fxLink = "http://hfx.link/2ax1";
updateTime = "2020-06-30T22:00+08:00";
}
};

生成解析json代码

复制代码

QString jsonText = "";
auto filePath = QString("D:/TestCode/build-Json2Code-Desktop_Qt_5_15_2_MinGW_64_bit-Release/2.json");//请补充json文件路径
QFile file(filePath);
if(file.open(QFile::ReadOnly))
{
auto data = file.readAll();
file.close();
jsonText = QString::fromUtf8(data);
}
QJsonParseError error;
auto doc = QJsonDocument::fromJson(jsonText.toUtf8(),&error);
if(error.error == QJsonParseError::NoError)
{
Undefined mUndefined;
auto rootObject = doc.object();
mUndefined.code = rootObject.value("code").toString();
mUndefined.fxLink = rootObject.value("fxLink").toString();
mUndefined.updateTime = rootObject.value("updateTime").toString();
auto nowObject = rootObject.value("now").toObject();
mUndefined.now.cloud = nowObject.value("cloud").toString();
mUndefined.now.dew = nowObject.value("dew").toString();
mUndefined.now.feelsLike = nowObject.value("feelsLike").toString();
mUndefined.now.humidity = nowObject.value("humidity").toString();
mUndefined.now.icon = nowObject.value("icon").toString();
mUndefined.now.obsTime = nowObject.value("obsTime").toString();
mUndefined.now.precip = nowObject.value("precip").toString();
mUndefined.now.pressure = nowObject.value("pressure").toString();
mUndefined.now.temp = nowObject.value("temp").toString();
mUndefined.now.text = nowObject.value("text").toString();
mUndefined.now.vis = nowObject.value("vis").toString();
mUndefined.now.wind360 = nowObject.value("wind360").toString();
mUndefined.now.windDir = nowObject.value("windDir").toString();
mUndefined.now.windScale = nowObject.value("windScale").toString();
mUndefined.now.windSpeed = nowObject.value("windSpeed").toString();
auto referObject = rootObject.value("refer").toObject();
auto licenseArray = referObject.value("license").toArray();
for (int i = 0; i < licenseArray.size(); i++)
{
mUndefined.refer.license[i] = licenseArray.at(i).toString();
}
auto sourcesArray = referObject.value("sources").toArray();
for (int i = 0; i < sourcesArray.size(); i++)
{
mUndefined.refer.sources[i] = sourcesArray.at(i).toString();
}
}
