美食不分貴賤，用最平凡的原料、最簡單的調料和最普通的手法做出美味的菜肴來才是美食的真谛。
這次，我做的醋溜白菜，近似魯菜的做法，使個這道菜酸甜濃郁、開胃下飯、老少鹹宜。",

接下來，我們開始今天的實戰，首先建立一個項目NutJoke
點選下一步
因為我們要網絡請求
是以我們需要在config.json中配置網絡請求權限
網絡請求的步驟
1、聲明網絡請求權限
在entry下的config.json中module字段下配置權限
"reqPermissions": [
{
"name": "ohos.permission.INTERNET"
}
]
2、支援http明文請求
預設支援https，如果要支援http，在entry下的config.json中deviceConfig字段下配置
"deviceConfig": {"default": {
"network": {
"cleartextTraffic": true
}
}},
3、建立HttpRequest
// 導入子產品
import http from '@ohos.net.http';
// 建立HttpRequest對象
let httpRequest = http.createHttp();
4、發起請求
GET請求（預設為GET請求）
// 請求方式：GET
getRequest() {
// 每一個httpRequest對應一個http請求任務，不可複用
let httpRequest = http.createHttp()
let url = "https://way.jd.com/jisuapi/search?keyword=白菜&num=10&start=0&appkey=7c913be32b690701cd994d804a6d4294"
httpRequest.request(url, (err, data) => {
if (!err) {
if (data.responseCode == 200) {
console.info('=====data.result=====' + data.result)
// 解析資料
//this.content= data.result;
// 解析資料
var cookModel: CookModel = JSON.parse(data.result.toString())
// 判斷接口傳回碼，0成功
if (cookModel.code == 1000) {
// 設定資料
this.future = cookModel.result.result.list.material
this.cookdetail = cookModel.result.result.list
this.isRequestSucceed = true;
console.info('=====data.result===this.content==' + cookModel.result.result.list.material)
} else {
// 接口異常，彈出提示
prompt.showToast({ message: "資料請求失敗" })
prompt.showToast({ message: jokeModel.error_code })
}
} else {
// 請求失敗，彈出提示
prompt.showToast({ message: '網絡異常' })
}
} else {
// 請求失敗，彈出提示
prompt.showToast({ message: err.message })
}
})
}
5、解析資料（簡單示例）
1.網絡請求到的json字元串
