在鸿蒙HarmonyOS 5中使用DevEco Studio实现企业微信功能

1. 开发环境准备

1. ​​安装DevEco Studio 3.1+​​：

   • 从华为开发者官网下载最新版DevEco Studio
   • 安装HarmonyOS 5.0 SDK

2. ​​项目配置​​：

   // module.json5
   {"module": {"requestPermissions": [{"name": "ohos.permission.INTERNET"},{"name": "ohos.permission.READ_MEDIA"},{"name": "ohos.permission.NOTIFICATION"}],"abilities": [{"name": "EntryAbility","type": "page","backgroundModes": ["dataTransfer"]}]}
   }

2. 企业微信核心功能实现

2.1 登录认证模块

// src/main/ets/model/WeComAuth.ts
import http from '@ohos.net.http';
import { Preferences } from '@ohos.data.preferences';export class WeComAuth {private static readonly CORP_ID = 'your_corp_id';private static readonly AGENT_ID = 'your_agent_id';private static readonly REDIRECT_URI = 'entry://com.your.app/auth';static async login(): Promise<boolean> {const httpRequest = http.createHttp();try {const response = await httpRequest.request(`https://open.work.weixin.qq.com/wwopen/sso/qrConnect?appid=${this.CORP_ID}&agentid=${this.AGENT_ID}&redirect_uri=${encodeURIComponent(this.REDIRECT_URI)}`,{ method: 'GET' });if (response.responseCode === 302) {const authCode = this.extractAuthCode(response.header['Location']);return this.exchangeToken(authCode);}return false;} catch (err) {console.error(`Login failed: ${err.code}, ${err.message}`);return false;}}private static async exchangeToken(authCode: string): Promise<boolean> {// 实现token交换逻辑}
}

2.2 消息列表页面

// src/main/ets/pages/MessageList.ets
import { WeComMessage } from '../model/WeComMessage';@Entry
@Component
struct MessageList {@State messages: Array<WeComMessage> = [];private timer: number = 0;aboutToAppear() {this.loadMessages();this.timer = setInterval(() => this.loadMessages(), 60000); // 每分钟刷新}aboutToDisappear() {clearInterval(this.timer);}async loadMessages() {try {this.messages = await WeComMessage.getRecentMessages();} catch (err) {console.error(`Load messages failed: ${err}`);}}build() {List({ space: 10 }) {ForEach(this.messages, (msg: WeComMessage) => {ListItem() {MessageItem({ message: msg })}}, (msg) => msg.id.toString())}.onScrollIndex((start: number) => {if (start > this.messages.length - 5) {this.loadMoreMessages();}})}
}

2.3 单聊/群聊页面

// src/main/ets/pages/ChatPage.ets
import { WeComChat } from '../model/WeComChat';@Entry
@Component
struct ChatPage {@State messages: Array<WeComMessage> = [];@State inputText: string = '';private chatId: string;build() {Column() {// 消息列表List({ space: 5 }) {ForEach(this.messages, (msg) => {ListItem() {if (msg.isSelf) {RightMessage({ message: msg })} else {LeftMessage({ message: msg })}}})}.layoutWeight(1)// 输入区域Row() {TextInput({ text: this.inputText }).onChange((value: string) => {this.inputText = value;}).layoutWeight(1)Button('发送').onClick(() => {if (this.inputText.trim()) {this.sendMessage();}})}.height(60).padding(10)}}async sendMessage() {try {await WeComChat.sendTextMessage(this.chatId, this.inputText);this.inputText = '';this.loadMessages();} catch (err) {console.error(`Send message failed: ${err}`);}}
}

3. 企业微信API封装

// src/main/ets/api/WeComApi.ts
import http from '@ohos.net.http';
import { WeComToken } from '../model/WeComToken';export class WeComApi {private static readonly BASE_URL = 'https://qyapi.weixin.qq.com/cgi-bin';static async get<T>(endpoint: string, params?: Record<string, string>): Promise<T> {const token = await WeComToken.getAccessToken();const httpRequest = http.createHttp();let url = `${this.BASE_URL}${endpoint}?access_token=${token}`;if (params) {url += '&' + Object.entries(params).map(([k, v]) => `${k}=${encodeURIComponent(v)}`).join('&');}try {const response = await httpRequest.request(url, { method: 'GET' });const result = JSON.parse(response.result as string);if (result.errcode !== 0) {throw new Error(`WeCom API Error: ${result.errmsg}`);}return result as T;} catch (err) {console.error(`API request failed: ${err}`);throw err;}}static async post<T>(endpoint: string, data: object): Promise<T> {// 类似GET方法的实现，使用POST请求}
}

4. 通知功能实现

// src/main/ets/utils/NotificationUtil.ts
import notification from '@ohos.notification';export class NotificationUtil {static showMessageNotification(sender: string, content: string) {try {notification.publish({id: 1,contentType: notification.ContentType.NOTIFICATION_CONTENT_BASIC_TEXT,content: {title: `新消息: ${sender}`,text: content,additionalText: '来自企业微信'}});} catch (err) {console.error(`Show notification failed: ${err}`);}}static cancelAll() {notification.cancelAll();}
}

5. 数据持久化

// src/main/ets/data/WeComStorage.ts
import { Preferences } from '@ohos.data.preferences';export class WeComStorage {private static readonly PREFERENCES_NAME = 'wecom_storage';private static preferences: Preferences | null = null;static async getInstance(): Promise<Preferences> {if (!this.preferences) {this.preferences = await Preferences.getPreferences(globalThis.abilityContext, this.PREFERENCES_NAME);}return this.preferences;}static async saveUserInfo(userInfo: object): Promise<void> {const prefs = await this.getInstance();await prefs.put('user_info', JSON.stringify(userInfo));await prefs.flush();}static async getUserInfo(): Promise<object | null> {const prefs = await this.getInstance();const userInfoStr = await prefs.get('user_info', '');return userInfoStr ? JSON.parse(userInfoStr) : null;}
}

6. 企业微信UI组件库

6.1 消息气泡组件

// src/main/ets/components/MessageBubble.ets
@Component
export struct MessageBubble {private message: WeComMessage;build() {Column() {Text(this.message.sender).fontSize(14).fontColor('#888888')Text(this.message.content).padding(10).backgroundColor(this.message.isSelf ? '#95EC69' : '#FFFFFF').borderRadius(8).margin({ top: 5 })Text(this.message.time).fontSize(12).fontColor('#AAAAAA').align(Alignment.End).margin({ top: 5 })}.width('80%').alignItems(this.message.isSelf ? HorizontalAlign.End : HorizontalAlign.Start)}
}

6.2 通讯录联系人组件

// src/main/ets/components/ContactItem.ets
@Component
export struct ContactItem {private contact: WeComContact;build() {Row() {Image(this.contact.avatar).width(50).height(50).borderRadius(25).margin({ right: 10 })Column() {Text(this.contact.name).fontSize(18)Text(this.contact.department).fontSize(14).fontColor('#888888')}.layoutWeight(1)Image($r('app.media.ic_arrow_right')).width(20).height(20)}.padding(10).width('100%')}
}

7. 企业微信主界面架构

// src/main/ets/MainPage.ets
@Entry
@Component
struct MainPage {@State currentTab: number = 0;build() {Tabs({ barPosition: BarPosition.End }) {TabContent() {MessageList()}.tabBar('消息')TabContent() {ContactList()}.tabBar('通讯录')TabContent() {Workbench()}.tabBar('工作台')TabContent() {MePage()}.tabBar('我')}.barMode(BarMode.Fixed).barWidth('100%').barHeight(60)}
}
