1. web端读取_constant表中version的信息

// web端读取_constant表中version的信息
async versionCheck() {
  setTimeout(async () => {
    await this.versionCheck();
  }, 10000);
  const versionConstantKey = 'version';
  let data;
  data = (
    await window.jianghuAxios({
      data: {
        appData: {
          pageId: 'allPage',
          actionId: 'getConstantList'
        }
      }
    })
  ).data.appData.resultData;
  const {rows: constantList} = data;
  localStorage.setItem('constantsArray', JSON.stringify(constantList));
  const serverVersionMap = constantList.find(item => item.constantKey === versionConstantKey);
  const serverVersion = JSON.parse(serverVersionMap.constantValue);
  window.serverVersion = serverVersion;
},
// 获取版本号
function getServerVersion() {
  if (window.serverVersion) {
    return JSON.stringify(window.serverVersion);
  }
}

2. APP端，每15秒读取version信息

//代码来源：/jianghuAppBrowser/jianghuBrowser/lib/Utils/LocalStorageUtil.dart
static Future<void> looperGetServerVersion(BuildContext context, String _runningPage) async {
  if(Constants.appId.value == 'browser' && Constants.isLoginPage) {
    return;
  }
  if(RenderKey.controller.value == null) {
    return;
  }
  if (WebViewHandler().complete) {
    String serverVersion = await RenderKey.controller.value!.runJavascriptReturningResult("getServerVersion()");
    if (serverVersion != "null" && serverVersion != "(null)") {
      try {
        Map<String, dynamic> versionMap = Utils.replaceAllJsonString(serverVersion);
        Constants.serverVersion = ServerVersionEntity.fromJson(versionMap);
        Constants.webVersion = Constants.serverVersion.version;
        if (Platform.isAndroid) {
          VersionUtil.updateApp(context);
        }
      } catch (error) {
        print("localStorage serverVersion error: $error");
      }
    }
  }
  if(_runningPage == runningPage) {
    Future.delayed(const Duration(seconds: 15), () async {
      looperGetServerVersion(context, _runningPage);
    });
  }
}

3. 下载并安装app

• 参考：/jianghuAppBrowser/jianghuBrowser/lib/Utils/VersionUtil.dart

• 流程：updateApp -> checkNeedUpdate -> downloadApk -> updateDialogRunUpdateBtn -> downloadImpl -> downloadFile -> installApk
