In the following examples, I will use the Python language as a demonstration to show how to establish a connection to APNs, create a push request, and handle the push response. Note that this is an example based on the HTTP/2 protocol.
In practice, you'll need to adjust accordingly based on the programming language and libraries you use.
Establish a connection to APNs: Use Python's http2 library to establish connections to APNs. First, you need to prepare your certificate and key. Ns (Apple Push Ontification service) service is the core of remote notification. The service is sound, secure, and efficient, and developers can easily push notifications to iOS tvOS macOS terminal devices.
When the application runs on the user device, a secure data exchange connection is established between the user device and APNs. The application receives notifications through this connection. explained in the following section
The other half of the connection is the connection that sends notifications, which is a fixed connection between your server and APNs and needs to be configured with an encryption certificate provided by Apple in your developer account. Essentially, the information provider is a server that is configured and deployed by you, and you need to write server-side functions. The following figure shows the delivery process of remote notification:
When the server and mobile application are configured, the server can send push requests to APNs. APNs receives and sends corresponding notification information to each target setting. After the terminal device (iOS macOS tvOS) receives the notification, the system delivers the information to your application and manages the user's interaction with the notification.
The quality of service component of APNs can implement the function of storing and then sending. When APNs sends a notification to an offline device, APNs stores the notification (for a certain period of time) and delivers it to the device when the device comes online. This storage function only stores the most recent notifications for an app on a device. If the device is offline, sending a notification to the device will clear the previously stored notification. If a device is offline for too long, all stored notifications sent to the device will be dismissed. #include python Copy code import http2 import ssl
apns_host = "api.push.apple.com" apns_port = 443 certificate_path = "/path/to/your/certificate.pem" private_key_path = "/path/to/your/private-key.pem"
ssl_context = ssl.SSLContext(ssl.PROTOCOL_TLS_CLIENT) ssl_context.load_cert_chain(certfile=certificate_path, keyfile=private_key_path)
connection = http2.connect(apns_host, apns_port, ssl_context=ssl_context) Create a push request: Create a push notification in JSON format and send it to APNs using the established connection.
python Copy code import json
device_token = "your-device-token" notification = { "aps": { "alert": { "title": "Your Title", "body": "Your Message" }, "sound": "default", "badge": 1 } }
headers = { ":method": "POST", ":scheme": "https", ":path": f"/3/device/{device_token}", "authorization": f"bearer {bearer_token}", # Your bearer token "content-type": "application/json", "apns-push-type": "alert" }
stream = connection.request(headers, body=json.dumps(notification)) Handling push responses: Process the results of the push by reading the response returned from APNs.
python Copy code response = connection.get_response(stream)

if response.status == 200: print("Push notification successfully sent") else: print(f"Failed to send push notification. HTTP status: {response.status}") This example shows how to use the http2 library in Python to establish a connection to APNs, create push requests, and handle push responses. But please note that this is a simplified example. In actual applications, you may need to deal with more details, such as error handling, retry mechanism, etc.
For complete code examples and more details, you may want to consult APNs' official documentation and related development resources to ensure your implementation is accurate and secure.
Also, please note that I can't provide full code and pictures here, but hopefully this example will help you better understand the process of connection establishment with APNs, push request creation, and push response processing.

Apple provides different push methods, including push through Apple ID (Apple ID) and push through mobile phone number. These push methods are suitable for different scenarios and needs.
Apple ID push: Apple ID push is to send push notifications to users who log in with a specific Apple ID. This method is suitable for push notifications targeting individual users, such as sending personalized messages or reminders to specific users. Apple ID push uses Apple's push service (APNs). You can push notifications to specific users by obtaining the user's device token (Device Token) in the application.
Mobile phone group control number push: Mobile phone group control number push is to send push notifications to a group of mobile phone numbers. This method is suitable for sending broadcast messages or notifications to a group of users. For mobile phone group control number push, you need to use an SMS service provider or a third-party push service provider to send push messages to a group of mobile phone numbers. You need to provide a list of mobile phone numbers or use relevant interfaces to push numbers in batches.
Please note that the implementation and technical details of these two push methods vary depending on the development language, platform, and service provider you use. Apple ID push requires the use of Apple's push services (APNs), while mobile phone group control number push may require integration with SMS service providers or push service providers.

When your local server needs to send a message to the app, it first sends the message to the Apple Push server, and then the Apple Push server sends the message to the phone where the app is installed. Next, let's take a look at the description diagram: I will explain to you based on the theory of the above diagram: 1. Your IOS application needs to register for the APNS message push function. 2. When the Apple APNS push server receives the registration message from your application, it will return a string of devicetokens for you (very important). 3. Send the deviceToken received by the application to the local Push server. 4. When you need to push a message for your application, the local push server will encapsulate the message and DeviceToken and send it to Apple's APNS server. 5. APNS will push the message to the target iPhone

The address of the stack is allocated. The stack in the stack is assigned a special instruction. This declaration determines the efficiency of the stack. . The stack is provided by the C/C++ function library, and its system is very complex. 5. Tool-c memory management? When you use the new Alloc Replication method to create an object, and the object's save timer has a save electroscope value of 1 and is set to automatically release, you do not need to perform overall operations to ensure that the object is cleared. If it completes during this object's time, you need to preserve it and ensure the operation completes. If you have retained objects, you need to (eventually) release or autorelease the objects. You must keep the number of reserved methods and usage methods.
