Question

推送通知可以完美地侧面加载到我的iOS手机中。我可以获取令牌并将其成功保存到Google Firestore数据库中并从中调用。调用它发出通知也可以按预期进行。如果我不在应用程序中，则会收到通知。如果我在应用程序中，则我的Notification Listener会运行良好。

在构建到iOS并将独立的应用程序部署到Apple服务器上的TestFlight之后，推送通知不再起作用。

这是我的构建。

这是我的组成部分：

  componentDidMount() {
    this.registerForPushNotifications();
  }

  componentWillUnmount() {
    if (!this.subscription) return;
    this.subscription.remove();
  }

  registerForPushNotifications = async () => {
    const PNToken = await this.props.MainStore.getLocal("PNToken");
    if (!PNToken) {
      try {
        const { status } = await Permissions.getAsync(
          Permissions.NOTIFICATIONS
        );
        let finalStatus = status;
        if (status !== "granted") {
          const { status } = await Permissions.askAsync(
            Permissions.NOTIFICATIONS
          );
          finalStatus = status;
          if (finalStatus !== "granted") {
            throw "Notification permission not granted";
          }
          const token = await Notifications.getExpoPushTokenAsync();
          this.props.MainStore.setPNToken(token);
          this.subscription = Notifications.addListener(
            this.handleNotification
          );
        }
      } catch (err) {
        console.warn("Permissions check error: ", err);
      }
    } else {
      this.props.MainStore.setPNToken(PNToken);
      this.subscription = Notifications.addListener(this.handleNotification);
    }
  };

  handleNotification = notification => {
    const store = this.props.NotificationStore;
    const sortedNotifications = sortMessages([
      ...store.state.notifications,
      { ...notification, read: false }
    ]);
    store.setState({
      notifications: sortedNotifications
    });
  };

Answer 1

我对推有很多沮丧，终于解决了这个问题。 1）在开发人员门户>证书，标识符和配置文件>标识符（您的应用程序）中启用推送通知 2）按照此处所述创建您的APNS密钥文件 https://fluffy.es/p8-push-notification/ 3）删除现有的配置文件 4）expo build：ios --clear-credentials，将您的P8文件上传到expo

Answer 2

从外观上看，您是在向Expo要求新的P8格式时向其提供旧的APNS证书。

您应该能够从Apple会员中心生成一个新的P8文件。

Answer 3

除了在 expo.io 上拥有正确的“Apple Distribution Certificate”、“Apple Provisioning File”和“Apple Push Key”之外，您还必须拥有正确的设备令牌。 >

首先，通过执行 expo credentials:manager 找到您的应用的 ExperienceId 它显示为经验：@user/slug，包标识符：com.xxx.xxx

然后获取您的令牌，如下所示

const token = (
   await Notifications.getExpoPushTokenAsync({
   experienceId: '@user/slug',  // <-- Experience shown above
   })
).data;
console.log('EXPO TOKEN: ', token); // Store this in the backend

将此设备令牌放入 expo 测试工具 (https://expo.io/notifications) 中，看看是否收到通知。

将Expo应用程序部署到Apple商店的TestFlight后，推送通知不起作用
