Expo SDK 39 推送通知不起作用

Question

谁能看到我在这里做错了什么？我升级到 expo SDK 39 并且推送通知停止工作。我已经调试了几天，似乎无法弄清楚。我可以看到令牌和消息正确输入，并且我可以看到 EXPO 在设置下具有通知访问权限。在 EXPO 之前，我能够使用推送通知运行测试，所以不确定 SDK v 39 出了什么问题。任何帮助将不胜感激。

用户发送聊天消息时运行的函数

const handleMessageSend = (msg) => {
    const index = messages.length ? messages[messages.length - 1].index + 1 : 0;
    const chat = {
      key: uid,
      index,
      receiver: [match.id],
      ...msg[0],
    };
    addChat(chat);
    setMessages([chat].concat(messages));
    let matchExpoToken = match.info.pushNotificationToken;
    if (matchExpoToken != "") {
      let messageBody = user.infoData.fullName + " sent you a new message";
      PushNotifications(matchExpoToken, messageBody);
    }
};

PushNotifications.js

// import * as Notifications from "expo-notifications"; //I have tried both of the imports with no luck
// import { Notifications, Permissions } from "expo";

const PushNotifications = async (matchExpoToken, messageBody) => {
  console.log("matchExpoToken", matchExpoToken, messageBody);
  const message = {
    to: matchExpoToken,
    sound: "default",
    title: "New Message",
    body: messageBody,
    data: { data: "new message" }, //todo: what is this "data"?
    _displayInForeground: true,
  };

  const response = await fetch("https://exp.host/--/api/v2/push/send", {
    method: "POST",
    headers: {
      Accept: "application/json",
      "Accept-encoding": "gzip, deflate",
      "Content-Type": "application/json",
    },
    body: JSON.stringify(message),
  });    
};

export default PushNotifications;

Answer 1

首先，您应该运行 expo install expo-notifications，因为 SDK 39 的正确版本是 expo-notifications@~0.7.2

如果如您所说，消息正在通过，那么我不能 100% 确定问题出在哪里，但如果我不得不猜测的话，它可能在您的通知侦听器 (addNotificationReceivedListener) 中的某个地方。最好的办法是查看the example from the docs 并从那里调试

编辑：实际上，如果这仅在 android 上，那么我认为另一个问题可能是您忘记在 app.json 文件中设置 useNextNotificationsApi 值：

{
  "expo": {
    ...
    "android": {
      ...
      "useNextNotificationsApi": true,
    }
  }
}
