js中JSON与QS的异同点

js中JSON与QS的异同点

相同点

• 二者可以进行序列化与反序列化；
• 二者都有相同的方法：序列化：stringify() 反序列化：parse()

不同点

• JSON.stringify()方法是将对象转化为JSON格式
• qs.stringify()方法是将对象转化为url格式
• JSON.parse()方法是将JSON数据转化为对象
• qs.parse()方法是将字符串转化为对象

实践出真知：

let par = {start: '2018-12-1T02:00:00Z',stop: '2018-12-2T02:00:00Z',step: '60',epoch: '2018-12-1T02:00:00Z',SemimajorAxis: '6711000',element: {Eccentricity: '0.01',Inclination: '43',ArgumentOfPerigee: '10',RAAN: '20',MeanAnomaly: '30',},propagatorType: '0',orbitDataType: '0'  
};const jsonS = JSON.stringify(par);console.log(jsonS);// {"start":"2018-12-1T02:00:00Z","stop":"2018-12-2T02:00:00Z","step":"60","epoch":"2018-12-1T02:00:00Z","element":{"SemimajorAxis":"6711000","Eccentricity":"0.01","Inclination":"43","ArgumentOfPerigee":"10","RAAN":"20","MeanAnomaly":"30"},"propagatorType":"0","orbitDataType":"0"}const jsonP = JSON.parse(jsonS);console.log(jsonP);// {start: "2018-12-1T02:00:00Z", stop: "2018-12-2T02:00:00Z", step: "60", epoch: "2018-12-1T02:00:00Z", element: {…}, …}const qsS = qs.stringify(par);console.log(qsS);// start=2018-12-1T02%3A00%3A00Z&stop=2018-12-2T02%3A00%3A00Z&step=60&epoch=2018-12-1T02%3A00%3A00Z&element%5BSemimajorAxis%5D=6711000&element%5BEccentricity%5D=0.01&element%5BInclination%5D=43&element%5BArgumentOfPerigee%5D=10&element%5BRAAN%5D=20&element%5BMeanAnomaly%5D=30&propagatorType=0&orbitDataType=0const qsP = qs.parse(qsS);console.log(qsP)// {start: "2018-12-1T02:00:00Z", stop: "2018-12-2T02:00:00Z", step: "60", epoch: "2018-12-1T02:00:00Z", element: {…}, …}
