hi bro

when the feature can be used?
i use the code in local. sending to firebase is successful, but the ios app no response.
show me the code.
can you help me to change?

Thanks!

package main

import (
	"context"
	firebase "firebase.google.com/go/v4"
	"firebase.google.com/go/v4/messaging"
	"fmt"
	"google.golang.org/api/option"
	"log"
	"os"
	"time"
)

func main() {
	println(os.Getwd())
	// 使用下载的服务账户密钥文件路径
	opt := option.WithCredentialsFile("./mePlus/to_firebase_ios/serviceAccountKey.json")
	app, err := firebase.NewApp(context.Background(), nil, opt)
	if err != nil {
		log.Fatalf("error initializing app: %v\n", err)
	}

	ctx := context.Background()
	client, err := app.Messaging(ctx)
	if err != nil {
		log.Fatalf("error getting Messaging client: %v\n", err)
	}
	now := time.Now()
	unixTime := time.Unix(1546304, 0)
	fcmOptions := new(messaging.APNSFCMOptions)
	fcmOptions.AnalyticsLabel = "test-live-activity"
	message := &messaging.Message{
		APNS: &messaging.APNSConfig{
			Headers: map[string]string{
				"apns-priority": "10",
				//"apns-topic":     "", // 必须添加的实时活动主题头
				"apns-push-type": "liveactivity", // 标识为实时活动推送
			},
			Payload: &messaging.APNSPayload{
				Aps: &messaging.Aps{
					Alert: &messaging.ApsAlert{
						Title: "123",
						Body:  "123",
					},
					//Sound:          "default",
					StaleDate:      &unixTime,
					Event:          messaging.LiveActivityEventStart,
					Attributes:     map[string]interface{}{},
					AttributesType: "MissedEnergy",
					ContentState:   map[string]interface{}{},
					DismissalDate:  &unixTime,
					Timestamp:      &now,
				},
			},
			FCMOptions:        fcmOptions,
			LiveActivityToken: "80a8a14077cc0e4392fbb5f4ae7bb329dbf0af5b8b384c5d1baba0a78b3227be3dbeba200dbfa150b8705f9364b0f5204d92267d82c093315911f9c9ed35be76a0c004c140c340d18644b2b7a513fd09",

	}

	// 发送消息
	response, err := client.Send(ctx, message)
	if err != nil {
		log.Fatalf("error sending message: %v\n", err)
	}

	// 打印响应
	fmt.Printf("成功发送消息: %s\n", response)
}

HI Guys,
Please let us know when this pr will be merged, we also have dependency on this.
If possible then can we prioritised this pr

@lahirumaramba Hi, I have a request regarding for code review of this 👀

The live_activity_token has to be defined in the same layer as the headers.
Therefore, using the current SDK, it's not possible to update LiveActivity remotely from the backend side. (the other hand, the payload can be resolved by using CustomData )

Please, code review if possible would be greatly appreciated 🙋🏼

[jonathanedey]

Hi @morikuni, Thanks for getting started on this. Could you remove the extra fields added and limit to just LiveActivityToken field. Thanks!

[morikuni]

@jonathanedey I’ve removed all the extra fields and now only include the LiveActivityToken. Could you review it again?

[jonathanedey]

Thanks again @morikuni for the contribution!

[Mickey0811]

As per review feedback, removed all extra Live Activity fields from Aps struct:

• Removed StaleDate, ContentState, Timestamp, Event, DismissalDate, AttributesType, and Attributes fields
• Removed LiveActivityEvent type and constants
• Updated tests to only test LiveActivityToken field
• Kept only the essential LiveActivityToken field in APNSConfig as requested

Why was this change reverted? How can I pass fields like Event and ContentState through an HTTP request

Or how should I construct the request parameters for LiveActivity? I see that currently there is only a type APNSPayload
struct {
Aps *Aps json:"aps,omitempty"
CustomData map[string]interface{} json:"-"
}
It seems that this struct cannot pass the aforementioned parameters out

@morikuni @jonathanedey

Has your issue been resolved? After sending the liveActivity request, does the iOS app respond

@xiaotuotuo321

[jonathanedey]

Hi @Mickey0811,

These fields can be set using the Aps struct's CustomData field:

&messaging.Message{
	Token: "test-token",
	APNS: &messaging.APNSConfig{
		LiveActivityToken: "live-activity-token",
		Payload: &messaging.APNSPayload{
			Aps: &messaging.Aps{
				CustomData: map[string]interface{}{
					"event": "start",
					"content-state": map[string]interface{}{
						"demo": 1,
					},
				},
			},
		},
	},
},

If that's not what you're seeing, could you please open a new issue and include as many details as you can (or even a minimal repro) so we can take look.
