Question

我正在使用Java为IOS发送firebase推送通知。下面是我的代码。

    public class SendNotifi {
    public final static String AUTH_KEY_FCM = "AIzaSyBgF...............";
    public final static String API_URL_FCM = "https://fcm.googleapis.com/fcm/send";
    // userDeviceIdKey is the device id you will query from your database     
    public static void pushFCMNotification(String userDeviceIdKey) throws     Exception{

    String authKey = AUTH_KEY_FCM;   // You FCM AUTH key
    String FMCurl = API_URL_FCM;     

    URL url = new URL(FMCurl);
    HttpURLConnection conn = (HttpURLConnection) url.openConnection();

    conn.setUseCaches(false);
    conn.setDoInput(true);
    conn.setDoOutput(true);

    conn.setRequestMethod("POST");
    conn.setRequestProperty("Authorization","key="+authKey);
    conn.setRequestProperty("Content-Type","application/json");

    JSONObject json = new JSONObject();
    json.put("to",userDeviceIdKey.trim());
    JSONObject info = new JSONObject();

    info.put("title", "Notificatoin Title - IOS");   // Notification title
    info.put("body", "Hello Test notification - IOS"); // Notification body
    info.put("badge", "1"); 
    json.put("notification", info);
    json.put("priority", "high");

    System.out.println("json : " +json);

    OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
    wr.write(json.toString());
    wr.flush();

    BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
    String inputLine;
    StringBuffer response = new StringBuffer();

    while ((inputLine = in.readLine()) != null) {
        response.append(inputLine);
    }
    in.close();

    System.out.println(response.toString());
    }
    public static void main(String main[])
    {
        try {
            SendNotifi.pushFCMNotification("e_0k8MPAXpI:APA91bFrz3MkWS0V9E_PJMGwtFppYhR6ap9rD53nB-Wxkosij1jDDuPDXRw__l4tzOOsGaEm_j02a20oJGLimKvTuZSqRs6aTcbizTMuYMp6_1jB4U7RCl2A_NdWEHIMlaAl6YN1o_Hv");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

IOS无法正常工作。

我在回复中获得了确认成功，但我没有在IOS中获得任何推动力。

提前致谢。

首先，我要提到 FCM 有两种类型的消息有效负载。通知和数据。请参阅此处的文档

通过 Firebase 通知控制台发送通知时，它将被视为通知负载。但是，如果您添加自定义数据，它会将其作为自定义键值对添加到负载中。

例如，在您的帖子中，FCM 负载应如下所示：

{
    "notification": {
    "body": "Some one invited you.",
    "title": "Friend request notification",
    "mutable-content": true,
    "icon": "myicon",
    "sound": "tri-tone"
},
"data": {
    "category": "provider-body-panel",
    "mutable-content": true,
    "click_action": "provider-body-panel"
    }
}
   "registration_ids": ["<REGISTRATION_TOKEN_HERE>"],
   "priority": "high"
}

怎么了？ mutable-content 应该是 mutable_content（注意下划线）并且应该与通知处于同一级别。（这个我可能误解了，但是）FCM 没有类别参数，click_action 已经对应它。请参阅此处的文档了解参数。

目前无法在使用 Firebase 通知控制台时设置 click_action 和 mutable_content 的值。您必须自己构建有效负载，如下所示：

 {
        "to": "<REGISTRATION_TOKEN_HERE>",
        "mutable_content" : true,
        "notification": {
            "body" : "Some one invited you.",
            "title": "Friend request notification",
            "click_action" : "provider-body-panel"
        }
    }

然后从您自己的应用服务器发送它。您也可以使用 Postman 或 cURL 来执行此操作。

这对我有用，希望你也是。
