比如伺服器上存有一段json資料。

{
"ret": 200,
"data": {
"name": "飛雲指令碼圈",
"url": "http://www.feiyunjs.com"
},
"msg": ""
}

我們要獲取其中的name值。

//此程式碼由飛雲指令碼圈原創（www.feiyunjs.com）
//介面採用PhalApi開發
let url = "http://news.feiyunjs.com/phalapi/public/";
let res = http.post(url, {
"service": "App.Zllgcimei.Imei",
"imei": device.getIMEI(),
 
"imei_tag": "測試標籤",
"whos": "feiyun",
});

let appName;
let html = res.body.string(); //取頁面html原始碼
// log(html)
let json = JSON.parse(html);
if (json.ret == "200") {
appName = json.data.name
} else {
log("請求失敗!")
}

log(appName)
