#鸿蒙通关秘籍#在HarmonyOS应用中怎样发送网络请求？

在HarmonyOS中发送网络请求，就像是你在网上购物，你需要告诉商家你要买什么，然后等待商家发货。我们通常使用Network Kit来发送HTTP请求：

import { http } from '@kit.NetworkKit';
import { BusinessError } from '@kit.BasicServicesKit';

let httpRequest = http.createHttp();
httpRequest.request("https://api.example.com/data", {
  method: http.RequestMethod.GET,
  expectDataType: http.HttpDataType.JSON,
}).then((err, data) => {
  if (!err) {
    console.log('Received data:', data.result);
  } else {
    console.error('Request failed:', err);
  }
  httpRequest.destroy();
}).catch((err) => {
  console.error('Request failed:', err);
  httpRequest.destroy();
});
