harmonyOS HTTP数据请求能用类

通用类

import http from '@ohos.net.http';// 调试开关
const Test: boolean = true;// API 地址
const Url: string = Test ? 'http://api.林.cn/' : 'http://api.林.cn/';export function request(api: string, method: string, data: any, token: string = ''): Promise<any> {return new Promise((resolve, reject) => {// 构建完整的 URLconst url = Url + api;// 创建 http 模块实例const httpRequest = http.createHttp();// 根据 'method' 参数确定请求方法const requestMethod = getRequestMethod(method);// 要添加的额外标头const customHeaders = {'Content-Type': 'application/json','Authorization': token // 在这里添加您的自定义标头};// 发起 HTTP 请求const promise = httpRequest.request(url,{method: requestMethod,extraData: data,connectTimeout: 60000, // 60 秒readTimeout: 60000,header: { ...customHeaders } // 扩展自定义标头});// 处理 Promise 的解析promise.then((responseData) => {if (responseData.responseCode === http.ResponseCode.OK) {resolve(responseData); // 使用响应数据解析 Promise} else {console.error('错误 - 响应代码: ' + responseData.responseCode);reject(new Error('HTTP 请求失败，响应代码为 ' + responseData.responseCode));}}).catch((error) => {console.error('错误: ' + JSON.stringify(error));reject(error); // 使用错误拒绝 Promise});});
}// 辅助函数，将方法字符串映射到 http.RequestMethod
function getRequestMethod(method: string): http.RequestMethod {switch (method.toLowerCase()) {case 'get':return http.RequestMethod.GET;case 'post':return http.RequestMethod.POST;case 'put':return http.RequestMethod.PUT;case 'delete':return http.RequestMethod.DELETE;// 针对其他 HTTP 方法需要添加更多的情况default:throw new Error(`不支持的 HTTP 方法: ${method}`);}
}

调用方式


import { request } from '../tools/httpUtils';
@Entry //入口
@Component  //装饰
struct Index {@State message: string = '啾啾救援' //双向绑定build() {Row() {Column() {Image("http://www.jjsos.cn/images/menu_logo.png").width(300).interpolation(ImageInterpolation.High)Text(this.message).fontSize(50).fontWeight(FontWeight.Bold)Button('确定').fontSize(30).backgroundColor("#000").onClick(()=>{this.message="JJSOS"})TextInput({placeholder:'用户名'}).type(InputType.PhoneNumber)TextInput({placeholder:'密码'}).type(InputType.Password)Button('确定登陆').onClick(()=>{const requestData = {"type": "1","username": "13176630659","password": "123456"};const  authToken:string=""const apiEndpoint = 'v2/auth/get-access-token';request(apiEndpoint, 'post', requestData, authToken).then((responseData) => {// 这时写代码 console.log('Response:', responseData);// Perform actions based on the response}).catch((error) => {// Handle errorsconsole.error('Error:', error);// Perform error-specific actions});})}.width('100%').backgroundColor("#aaa")}.height('100%').backgroundColor("#aaa")}
}function authToken(apiEndpoint: string,arg1: string,requestData: { type: string; username: string; password: string; },authToken: any) {
