}封装一个HttpUtil
对外开放一个httpRequestGet和httpRequestPost用于get和post请求 import { http } from kit.NetworkKit;
import ResponseResult from ./ResponseResult;/*** Initiate an HTTP GET request to the specified URL.*/
export function httpRequestGet(url: string) {return httpRequest(url, http.RequestMethod.GET);
}/*** Initiate an HTTP POST request to the specified URL.*/
export function httpRequestPost(url: string, newsData: string) {return httpRequest(url, http.RequestMethod.POST, newsData);
}/*** Initiates an HTTP request to a given URL.** param url URL for initiating an HTTP request* param method Request method.* param extraData Additional data of the request.* returns Returns {link ResponseResult}.*/
function httpRequest(url: string, method: http.RequestMethod, params?: string): PromiseResponseResult {let httpRequest http.createHttp();let responseResult httpRequest.request(url, {method: method,header: {Content-Type: application/json},extraData: params});let serverData new ResponseResult();// Processes the data and returns.return responseResult.then((value: http.HttpResponse) {if (value.responseCode 200) {// Obtains the returned data.let result ${value.result};let resultJson: ResponseResult JSON.parse(result);if (resultJson.code 000000) {serverData.data resultJson.data;}serverData.code resultJson.code;serverData.msg resultJson.msg;} else {serverData.msg Network request failed, please try later!${value.responseCode};}return serverData;}).catch(() {serverData.msg Network request failed, please try later!;return serverData;});
}ResponseResult为服务端返回的基本结构 export default class ResponseResult {/*** Code returned by the network request: success, fail.*/code: string;/*** Message returned by the network request.*/msg: string | Resource;/*** Data returned by the network request.*/data: string | Object | ArrayBuffer;constructor() {this.code ;this.msg ;this.data ;}}
