美食不分贵贱,用最平凡的原料、最简单的调料和最普通的手法做出美味的菜肴来才是美食的真谛。

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
在entry下的config.json中module字段下配置权限
"reqPermissions": [
{
"name": "ohos.permission.INTERNET"
}
]
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
}
}},
// 导入模块
import http from '@ohos.net.http';
// 创建HttpRequest对象
let httpRequest = http.createHttp();
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 })
}
})
}
