针对浏览器 Web 组件清除缓存相关,具体实现如下 code 实例所示:

/*公共方法类*/
export class PublicUtils {/*获取缓存大小*/static async getCacheSize(): Promise<number> {try {let bundleStats = await storageStatistics.getCurrentBundleStats()let size = bundleStats.cacheSize / 1024 / 1024return Math.round(size)} catch (e) {console.error(`[PublicUtils] - 获取缓存大小: ErrorCode: ${e.code},  Message: ${e.message}`);return 0}}/*清除 Web 浏览器缓存(单个 Web 组件) Rom & Ram*/static clearWebCache(webView: web_webview.WebviewController, state: boolean): string {if (webView) {if (state) { // Rom & Ram: 本地 loc 和 缓存try {webView.removeCache(true);return '浏览器缓存清除成功';} catch (error) {let e: business_error.BusinessError = error as business_error.BusinessError;console.error(`[PublicUtils] - 清除缓存: ErrorCode: ${e.code},  Message: ${e.message}`);return '浏览器缓存清除失败:' + e.message;}} else { // Ram: 仅缓存try {webView.removeCache(false);return '浏览器缓存清除成功';} catch (error) {let e: business_error.BusinessError = error as business_error.BusinessError;console.error(`[PublicUtils] - 清除缓存: ErrorCode: ${e.code},  Message: ${e.message}`);return '浏览器缓存清除失败:' + e.message;}}} else {return '浏览器缓存清除失败: 无效的组件';}}
}

import { PublicUtils } from '../utils/PublicUtils'// 获取缓存
PublicUtils.getCacheSize().then((res) => {console.log('[获取缓存]: ', res)this.detail = res.toString()
})// 清除缓存
PublicUtils.clearWebCache(this.webView, state);
