uniapp生成app包引导用户开启通知权限和热更新

引导用户开启通知权限

export function setPermissions() {
  // #ifdef APP-PLUS 
  if (plus.os.name == 'Android') {
    var main = plus.android.runtimeMainActivity();
    var pkName = main.getPackageName();
    var uid = main.getApplicationInfo().plusGetAttribute("uid");
    var NotificationManagerCompat = plus.android.importClass("android.support.v4.app.NotificationManagerCompat");
    if (NotificationManagerCompat == null) {
      NotificationManagerCompat = plus.android.importClass("androidx.core.app.NotificationManagerCompat");
    }
    var areNotificationsEnabled = NotificationManagerCompat.from(main).areNotificationsEnabled();
    if (!areNotificationsEnabled) {
      uni.showModal({
        title: '通知权限开启提醒',
        content: '您还没有开启通知权限，无法接受到消息通知，请前往设置！',
        showCancel: true,
        confirmText: '去设置',
        confirmColor: '#36d',
        cancelText: '暂不',
        cancelColor: '#999',
        success: function (res) {
          if (res.confirm) {
            var Intent = plus.android.importClass('android.content.Intent');
            var Build = plus.android.importClass("android.os.Build");
            if (Build.VERSION.SDK_INT >= 26) {
              var intent = new Intent('android.settings.APP_NOTIFICATION_SETTINGS');
              intent.putExtra('android.provider.extra.APP_PACKAGE', pkName);
            } else if (Build.VERSION.SDK_INT >= 21) {
              var intent = new Intent('android.settings.APP_NOTIFICATION_SETTINGS');
              intent.putExtra("app_package", pkName);
              intent.putExtra("app_uid", uid);
            } else {
              intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
              var uri = Uri.fromParts("package", mainActivity.getPackageName(), null);
              intent.setData(uri);
            }
            main.startActivity(intent);
          }
        }

      });
    }
  } else if (plus.os.name == 'iOS') {
    var isOn = undefined;
    var types = 0;
    var app = plus.ios.invoke('UIApplication', 'sharedApplication');
    var settings = plus.ios.invoke(app, 'currentUserNotificationSettings');
    if (settings) {
      types = settings.plusGetAttribute('types');
      plus.ios.deleteObject(settings);
    } else {
      types = plus.ios.invoke(app, 'enabledRemoteNotificationTypes');
    }
    plus.ios.deleteObject(app);
    isOn = (0 != types);
    if (isOn == false) {
      uni.showModal({
        title: '通知权限开启提醒',
        content: '您还没有开启通知权限，无法接受到消息通知，请前往设置！',
        showCancel: true,
        confirmText: '去设置',
        confirmColor: '#36d',
        cancelText: '暂不',
        cancelColor: '#999',
        success: function (res) {
          if (res.confirm) {
            var app = plus.ios.invoke('UIApplication', 'sharedApplication');
            var setting = plus.ios.invoke('NSURL', 'URLWithString:', 'app-settings:');
            plus.ios.invoke(app, 'openURL:', setting);
            plus.ios.deleteObject(setting);
            plus.ios.deleteObject(app);
          }
        }
      });
    }
  }
  // #endif 
}

热更新包

	//安装热更新
	onMounted(() => {
		//#ifdef APP-PLUS
		let baseInfo = uni.getAppBaseInfo();
		plus.runtime.getProperty(plus.runtime.appid, widgetInfo => {
			getApp().globalData.version = widgetInfo.version;
			let param_data = {
				version: widgetInfo.version, //版本号
				os_name: plus.os.name, //应用名称
				appid: baseInfo.appId,
			};
			uni.request({
				url: '*****', //接口判断是否为新版本
				data: param_data,
				success: result => {
					var data = result.data.data;
					if (data.status && data.url) {
						if (widgetInfo.version != result.data.data.versions) {
							uni.showModal({
								title: '发现新版本',
								content: '确认下载更新',
								success: res => {
									if (res.confirm) {
										//当用户确定更新，执行更新
										doUpData(data);
									}
								},
							});
						}
					}
				},
			});
		});
		//#endif
	})
//更新方法
function doUpData(data) {
	uni.showLoading({
		title: '更新中……',
	});
	console.log('test')
	uni.downloadFile({
		url: data.url,
		success: downloadResult => {
			uni.hideLoading();
			if (downloadResult.statusCode == 200) {
				uni.showModal({
					title: '',
					content: '更新成功，确定现在重启吗？',
					confirmText: '重启',
					confirmColor: '#EE8F57',
					success: function(res) {
						if (res.confirm) {
							plus.runtime.install(
								//安装
								downloadResult.tempFilePath, {
									force: true,
								},
								function(res) {
									plus.runtime.restart();
								}
							);
						}
					},
				});
			}
		},
	});
}

然后点击这个打包给后端


注意:这个版本号每次打包 必须修改
