接下来，我们开始今天的实战，首先创建一个项目NutJoke
点击下一步
因为我们要网络请求
所以我们需要在config.json中配置网络请求权限
网络请求的步骤
1、声明网络请求权限
在entry下的config.json中module字段下配置权限
“reqPermissions”: [
{
“name”: “ohos.permission.INTERNET”
}
]
2、支持http明文请求
默认支持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、创建HttpRequest
// 导入模块
import http from @ohos.net.http;
// 创建HttpRequest对象
let httpRequest = http.createHttp();
4、发起请求
GET请求（默认为GET请求）
// 请求方式：GET
getRequest() {
// 每一个httpRequest对应一个http请求任务，不可复用
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)
// 解析数据
//this.content= data.result;
// 解析数据
var cookModel: CookModel = JSON.parse(data.result.toString())
// 判断接口返回码，0成功
if (cookModel.code == 1000) {
// 设置数据
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 {
// 接口异常，弹出提示
prompt.showToast({ message: “数据请求失败” })
prompt.showToast({ message: jokeModel.error_code })
}
} else {
// 请求失败，弹出提示
prompt.showToast({ message: 网络异常 })
}
} else {
// 请求失败，弹出提示
prompt.showToast({ message: err.message })
}
})
}
5、解析数据（简单示例）
1.网络请求到的json字符串
