Onesignal - 如何使用 python 向 android 设备发送推送通知？

Question

I am trying to send a push notifications to all subscribed users.

Depending on onesignal api documentation , the content must be a valid language which i really don't understand!! why i should send the data like as mentioned in the documentation

contents: {"en":"English Text!}

Here is my python code:

import requests
import json

header = {
    "Content-Type": "application/json; charset=utf-8",
    "Authorization": "Basic xxxx"
}

payload = {
            "app_id": "xxxx",
            "included_segments": ["All"],
            "contents":{"en":"notification","ru":"уведомление"}
            "data": {
                "body": "Hello my friend! we added a new post!",
                "fromProjectNumber": "xxxxxx",
                "groupKey": "myapp_grp",
                "groupMessage": "MyApp",
                "largeIcon": "https://example.com/icon.png",
                "lockScreenVisibility": 1,
                "priority": 5,
                "smallIcon": "icon",
                "title": "New post",
            }
        }

req = requests.post("https://onesignal.com/api/v1/notifications", headers=header, data=json.dumps(payload))

I am receiving the notification, but no data shows up, in fact. i am getting only the text in contents.

Finally i recognized that the payload that i am sending is incorrect, this how it should looks like:

payload = {
    "app_id": "xxxx",
    "included_segments": ["All"],
    "contents": {"en": "Lorem ipsum dolor amit falit matit", "ru": "Lorem ipsum dolor amit falit matit"},
    "android_gcm_sender_id": "620941305752",
    "android_group": "myapp_grp",
    "android_group_message": "MyApp",
    "large_icon": "https://img.onesignal.com/n/icon.png",
    "android_visibility": 1,
    "priority": 5,
    "android_sound":"notification",
    "headings": {"en": "New post", "ru": "Мы опубликовали новую статью"}
}

Also, I've found a cool python library for sending push notifications through Onesignal A Python client library for OneSignal API. , this code is working as needed:

payload = {
    "included_segments": ["All"],
    "contents": {"en": "Lorem ipsum dolor amit ", "ru": "Lorem ipsum dolor amit"},
    "android_gcm_sender_id": "XXXX",
    "android_group": "myapp_grp",
    "android_group_message": "MyApp",
    "large_icon": "https://img.onesignal.com/n/icon.png",
    "android_visibility": 1,
    "priority": 5,
    "android_sound":"notification",
    "headings": {"en": "New post NazarNews TV", "ru": "Мы опубликовали новую статью"}
}

# create a onesignal client
onesignal_client = onesignal_sdk.Client(
    app_auth_key="XXXX",
    app_id="XXXX"
)

# create a notification
new_notification = onesignal_sdk.Notification(post_body=payload)

# Send notification
onesignal_response = onesignal_client.send_notification(new_notification)

But i don't know why there is no notification sound!
