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

Question

推送通知可以完美地侧载到我的 iOS 手机上。我可以获取令牌并成功将其保存到我的 Google Firestore 数据库中并从中调用它。调用它以发送通知也可以按预期工作。如果我不在应用程序中，我会收到通知。如果我在应用程序中，我的通知侦听器运行良好。

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

这是我的作品。

这是我的组件：

  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 push 最终解决了这个问题感到非常沮丧。 1) 在 Developer portal > Certificates, Identifiers & Profiles > Identifier (of your app) 中启用推送通知 2) 如此处所述创建您的 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，上传你的P8文件到expo

Answer 2

从外观上看，当 Expo 要求新的 P8 格式时，您正在向它提供旧的 APNS 证书。

您应该能够从 Apple 会员中心生成新的 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。 p>

首先，通过执行expo credentials:manager找到你应用的experienceId 它显示为 经验：@user/slug，包标识符：com.xxx.xxx

然后按如下方式获取您的令牌

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），看看是否收到通知。
