:root{--mermaid-font-family:"trebuchet ms",verdana,arial,sans-serif;} RequestAxios static baseApiUrl: string static baseTrackApiUrl: string -instance: AxiosInstance initBaseUrl() get() post() -setupInterceptors() -getOpenID() HttpResponse code: number msg: string data: T HMRouterMgr LoginStorageHandel 二、核心实现详解
2.1 请求初始化系统
export class RequestAxios {// 静态基础URL配置static baseApiUrl: string ;static baseTrackApiUrl: string ;// Axios实例化配置private instance: AxiosInstance axios.create({baseURL: apiProBaseURL,timeout: 10000, // 10秒超时httpAgent: new http.HttpAgent({ keepAlive: true }) // 启用连接池});// 构造器逻辑constructor(requestType: RequestType) {this.setupInterceptors(requestType);this.enableNetworkMonitor(); // 鸿蒙网络状态监听}// 动态端点配置static initBaseUrl(info: initModel) {this.baseApiUrl info.apiUrl;this.baseTrackApiUrl info.trackApiUrl;if (__DEV__) {console.debug(Endpoint Configured: API-${this.baseApiUrl}Track-${this.baseTrackApiUrl});}}
}2.2 拦截器引擎实现
请求拦截管道
private setupInterceptors(requestType: RequestType) {// 请求拦截器this.instance.interceptors.request.use((config: InternalAxiosRequestConfig) {// 网络可达性检测const netHandle connection.getDefaultNetSync();if (netHandle.netId 100) {LogUtil.e(Tag, 网络不可用终止请求);return Promise.reject(new Error(NETWORK_UNAVAILABLE));}// 隐私协议状态检查if (!privacyAuth.getPrivacyAuthInfo()) {LogUtil.e(Tag, 隐私协议未同意);return Promise.reject(new Error(PRIVACY_UNAUTHORIZED));}// 动态端点配置switch (requestType) {case RequestType.api:config.baseURL RequestAxios.baseApiUrl;break;case RequestType.trackApi:config.baseURL RequestAxios.baseTrackApiUrl;break;}// 凭证注入体系const openID this.getOpenID();config.headers {...config.headers,openId: openID,versionCode: AppUtil.getVersionCode(),language: AreaCode.Empty,zone: PreferencesUtil.getSync(StorageConstant.currentZoneStorage, Asia/Shanghai),X-Device-ID: deviceInfo.deviceId // 鸿蒙设备唯一标识};// 特殊接口处理if (config.url?.includes(getSeletedInCountry)) {HMRouterMgr.push({ pageUrl: dialog://NetworkLoadingDialog });}return config;},(error) Promise.reject(error));
}响应处理中枢
// 响应拦截器
this.instance.interceptors.response.use((response: AxiosResponse) {// 关闭全局加载态if (response.config.url?.includes(getSeletedInCountry)) {HMRouterMgr.getPathStack(MAIN_NAVIGATION_ID)?.removeByName(dialog://NetworkLoadingDialog);}// 统一状态码处理const validCodes [200, 505, 205, 0, 201];if (!validCodes.includes(response.data.code)) {LogUtil.e(Tag, 异常状态码:, response.data.code);throw new Error(INVALID_STATUS_CODE:${response.data.code});}return response.data;},(error: AxiosErrorAPIErrorType) {// 异常统一处理HMRouterMgr.removeDialog();const errorInfo {code: error.response?.status || 500,msg: error.response?.data?.msg || 未知错误,config: error.config};// 网络异常特殊处理if (error.message.includes(NETWORK_UNAVAILABLE)) {errorInfo.msg 网络连接不可用;}LogUtil.e(Tag, 请求失败:, errorInfo);return Promise.reject(errorInfo);}
);2.3 凭证管理体系
private getOpenID(): string {// 多级凭证获取策略let openID LoginStorageHandel.openID;if (!openID) {openID PreferencesUtil.getSync(StorageConstant.currentOpenIdStorage, default_openID) as string;// 跨设备ID同步if (openID default_openID) {openID this.generateCrossDeviceID();PreferencesUtil.setSync(StorageConstant.currentOpenIdStorage,openID);}}return openID;
}private generateCrossDeviceID(): string {// 生成跨设备统一标识const deviceHash crypto.createHash(sha256).update(deviceInfo.deviceId).digest(hex);return cross_${deviceHash.substr(0, 16)};
}三、最佳工程实践
3.1 配置管理方案
// 环境配置模板
export const envConfig {production: {apiUrl: https://api.prod.example.com,trackApiUrl: https://track.prod.example.com},staging: {apiUrl: https://api.stage.example.com,trackApiUrl: https://track.stage.example.com}
};// 初始化示例
RequestAxios.initBaseUrl(process.env.NODE_ENV production ? envConfig.production : envConfig.staging
);3.2 异常监控体系
// 错误边界处理
class RequestErrorBoundary {private static reportError(error: Error) {const errorData {timestamp: new Date().toISOString(),deviceInfo: {model: deviceInfo.model,osVersion: deviceInfo.osVersion},errorStack: error.stack};// 异常上报trackApiRequest.post(/errors, errorData);}static wrapRequestT(promise: PromiseT) {return promise.catch((error) {this.reportError(error);throw error;});}
}// 使用示例
RequestErrorBoundary.wrapRequest(apiRequest.getUserInfo(/user)
);四、性能优化策略
4.1 缓存加速方案
const cacheStore new dataCache.Cache({maxAge: 300000, // 5分钟缓存maxSize: 1024 * 1024 // 1MB存储
});async getWithCacheT(url: string) {const cacheKey req_${md5(url)};if (cacheStore.has(cacheKey)) {return cacheStore.get(cacheKey);}const result await this.getT(url);cacheStore.set(cacheKey, result);return result;
}4.2 智能节流控制
private throttleQueue new Mapstring, Promiseany();async throttledGetT(url: string) {if (this.throttleQueue.has(url)) {return this.throttleQueue.get(url);}const promise this.getT(url).finally(() {this.throttleQueue.delete(url);});this.throttleQueue.set(url, promise);return promise;
