3.开发过程

安装axios

OpenHarmony三方库中心仓：https://ohpm.openharmony.cn/#/cn/home 项目中执行

ohpm install [@ohos](/user/ohos)/axios

主体业务实现(因实际业务api的返回值不是固定的所以未封装code判断到Util里面，可根据个人情况进行改造)HttpUtil.ets

import axios, { AxiosResponse } from '[@ohos](/user/ohos)/axios';
import ResponseResult from '../common/bean/ResponseResult';
import { http } from '@kit.NetworkKit';
import { Apis } from './Apis';
import Logger from './Logger';
const TAG = ‘[HttpUtil]’;
export class HttpUtil {
public static  request(url: string, params: ESObject = {}, method = http.RequestMethod.GET,
contentType?: string): Promise<ResponseResult> {
axios.defaults.headers[‘Content-Type’] =
contentType || method === http.RequestMethod.POST ? ‘application/json’ : ‘application/x-www-form-urlencoded’;
let responseResult:Promise<AxiosResponse<string>>  =  axios.request({
url,
method,
params
});
let serverData: ResponseResult = new ResponseResult();
return responseResult.then((response: AxiosResponse<string>)=>{
Logger.info(TAG, “网络请求：” + “接口:” + Apis.BASE_Url + url + " 参数: " + JSON.stringify(params) + “返回结果:” + JSON.stringify(response.data));
if (response.status == http.ResponseCode.OK) {
serverData = JSON.parse(JSON.stringify(response.data));
} else {
serverData.resCode = Apis.BASE_ERROR_CODE;
serverData.resMsg = ${<span class="hljs-string"><span class="hljs-string">'网络错误，请联系管理员：'</span></span>}&amp;${response.status};
}
return serverData;
}).catch((e:object) => {
Logger.info(TAG,“网络请求异常：”+ JSON.stringify(e))
serverData.resCode = Apis.BASE_ERROR_CODE;
serverData.resMsg = ‘网络错误，请联系管理员’;
return serverData;
})
}
}

业务调用HomeViewModel.ets(获取banner)

import BannerBean from '../common/bean/BannerBean';
import ResponseResult from '../common/bean/ResponseResult';
import { Apis } from '../utils/Apis';
import { HttpUtil } from '../utils/HttpUtil';
export class HomeViewModel {
getBannerList(): Promise<BannerBean[]> {
return new Promise((resolve: Function, reject: Function) => {
HttpUtil.request(Apis.BASE_Url+Apis.bannerList).then((res: ResponseResult) => {
if (res.resCode == 1) {
resolve(res.data);
} else {
reject(res.resMsg);
}
}).catch((res:object) => {
reject(JSON.stringify(res));
});
});
}
}
export default new HomeViewModel();

ResponseResult.ets

export default class ResponseResult {
  resCode: number |string;
  resMsg: string | Resource;
  data: string | Object | ArrayBuffer | null;
constructor() {
this.resCode = 0;
this.resMsg = ‘’;
this.data = null;
}
}

Logger.ets

import { hilog } from '@kit.PerformanceAnalysisKit';
export class Logger {
private domain: number;
private prefix: string;
private format: string = %{public}s, %{public}s;
constructor(prefix: string) {
this.prefix = prefix;
this.domain = 0xFF00;
}
debug(…args: string[]) {
hilog.debug(this.domain, this.prefix, this.format, args);
}
info(…args: string[]) {
hilog.info(this.domain, this.prefix, this.format, args);
}
warn(…args: string[]) {
hilog.warn(this.domain, this.prefix, this.format, args);
}
error(…args: string[]) {
hilog.error(this.domain, this.prefix, this.format, args);
}
fatal(…args: string[]) {
hilog.fatal(this.domain, this.prefix, this.format, args);
}
isLoggable(level: number) {
hilog.isLoggable(this.domain, this.prefix, level);
}
}
export default new Logger(’[WoNiu]’);
