[英]Push Notification not received - AWS SNS and Expo
I am trying to use AWS SNS to send my push notifications.我正在尝试使用 AWS SNS 发送我的推送通知。 I am just testing for now.
我现在只是在测试。 I have already created the platform and the endpoint in SNS.
我已经在 SNS 中创建了平台和端点。 When I send a push notification from the SNS console I received it without a problem.
当我从 SNS 控制台发送推送通知时,我毫无问题地收到了它。 This is how I am sending it from there:
这就是我从那里发送它的方式:
{"GCM": "{ \"notification\": {\"title\": \"Test\", \"body\": \"It works\" } }"}
Now, I am trying to send push notifications programmatically using the Javascript SDK, but I can't get it to work correctly.现在,我正在尝试使用 Javascript SDK 以编程方式发送推送通知,但我无法使其正常工作。 I am testing the app on my real Android phone.
我正在我的真实 Android 手机上测试该应用程序。 Which connects to my server app hosted locally.
它连接到我在本地托管的服务器应用程序。 When the app opens, I press a button that sends an http request to my local server app, which then tries to send the push notification.
当应用程序打开时,我按下一个按钮,向我的本地服务器应用程序发送一个 http 请求,然后它会尝试发送推送通知。
What is strange is that I get the message that the push notification was sent, but I never receive it on my phone:奇怪的是,我收到推送通知已发送的消息,但我从未在手机上收到它:
Push notification sent successfully!!!! {
ResponseMetadata: { RequestId: 'XXX-5913-996f-b8ec0c010eac' },
MessageId: 'XXX-5308-98e3-0689b03df4b7'
}
This is the code that I have in my local server app:这是我在本地服务器应用程序中的代码:
module.exports.sendPushNotification = () => {
var sns = new AWS.SNS({ apiVersion: '2010-03-31', region: 'us-east-1'});
var params = {
Message: `{
"GCM": "{ \"notification\": {\"title\": \"Test\", \"body\": \"It works\" } }"
}`,
TargetArn: "######My Device ARN#######"
};
sns.publish(params, function(err, data) {
if (err) {
console.log("There was an error sending the push notification----> ", err)
} // an error occurred
else{
console.log("Push notification sent successfully!!!! ", data);
} // successful response
});
}
I have tried to change the formatting of the Message and still nothing.我试图更改消息的格式,但仍然没有。 What am I doing wrong?
我究竟做错了什么?
Thanks to a person called "Jitesh Prajapati" who gave me the answer to this on Facebook. This is how it works:感谢一个叫“Jitesh Prajapati”的人,他在 Facebook 上给了我这个问题的答案。它是这样工作的:
var sns = new AWS.SNS({ apiVersion: '2010-03-31', region: 'us-east-1'})
let notification = JSON.stringify({
'notification': {
'title': "Notification Title",
'body': "Your message goes here",
'data': {}
}
});
var params = {
Message: JSON.stringify({
GCM: notification
}),
MessageStructure: "json",
TargetArn: "### Your target ARN ###"
};
sns.publish(params, function(err, data) {
if (err) {
console.log("There was an error sending the push notification----> ", err)
} // an error occurred
else{
console.log("Push notification sent successfully!!!! ", data);
} // successful response
});
