接下來，我們開始今天的實戰(zhàn)，首先創(chuàng)建一個項目NutJoke

點擊下一步

因為我們要網(wǎng)絡(luò)請求

所以我們需要在config.json中配置網(wǎng)絡(luò)請求權(quán)限

網(wǎng)絡(luò)請求的步驟

1、聲明網(wǎng)絡(luò)請求權(quán)限

在entry下的config.json中module字段下配置權(quán)限

"reqPermissions": [

{

"name": "ohos.permission.INTERNET"

}

]

2、支持http明文請求

默認(rèn)支持https，如果要支持http，在entry下的config.json中deviceConfig字段下配置

"deviceConfig": {"default": {

"network": {

"cleartextTraffic": true

}

}},

3、創(chuàng)建HttpRequest

// 導(dǎo)入模塊

import http from '@ohos.net.http';

// 創(chuàng)建HttpRequest對象

let httpRequest = http.createHttp();

4、發(fā)起請求

GET請求（默認(rèn)為GET請求）

?

// 請求方式：GET

getRequest() {

// 每一個httpRequest對應(yīng)一個http請求任務(wù)，不可復(fù)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)

// 解析數(shù)據(jù)

//this.content= data.result;

// 解析數(shù)據(jù)

var cookModel: CookModel = JSON.parse(data.result.toString())

// 判斷接口返回碼，0成功

if (cookModel.code == 1000) {

// 設(shè)置數(shù)據(jù)

?

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: "數(shù)據(jù)請求失敗" })

prompt.showToast({ message: jokeModel.error_code })

}

?

} else {

// 請求失敗，彈出提示

prompt.showToast({ message: '網(wǎng)絡(luò)異常' })

}

} else {

// 請求失敗，彈出提示

prompt.showToast({ message: err.message })

}

})

}

5、解析數(shù)據(jù)（簡單示例）
