⚡ HTTP/2 Apple Push Notification Service (APNs) push provider for Go — Send push notifications to iOS, tvOS, Safari and OSX apps, using the APNs HTTP/2 protocol.

apns2's Issues

How can i push multiple notifications in one time?

The delay is too long for me while pushing notifications one by one, i am seeking for a way that could push a batch of notifications in a time, is there any suggestions for me?

Install instructions

It would be great if there were detailed install instructions. What is included in the readme is not clear.

What am I supposed to do after running the go get commands?

Apns2 error: dial udp 114.114.114.114:53: i/o timeout

Hi:
when I push apns notice, it return dial udp 114.114.114.114:53: i/o timeout. I think the APNS2 can't connect the Apple's server. How can I fix it?
Below is the error:

Only the first build the push connection has this error.

here is mine code:
func pushApnsAndSaveException(message []byte, client *apns.Client) {
pMsg := pMessage.PushMessage{}
json.Unmarshal(message, &pMsg)

payload := NewPayload()
payload.Alert(pMsg.Content)
payload.Badge(pMsg.Count)
payload.Custom("id", pMsg.Id)
payload.Custom("type", pMsg.Type)
payload.Custom("contentType", pMsg.ContentType)
payload.Sound("sms-received1.caf")

payloadByte, err := json.Marshal(payload)
if err != nil {
    log.Println("json marshal error:", err)
}

log.Println("payload json: ", string(payloadByte))
notification := &apns.Notification{}
notification.DeviceToken = pMsg.Token

notification.Topic = apnsConst.ApnsTopic
notification.Priority = 10
notification.Payload = payloadByte
l4g.Info("payload btye: ", string(payloadByte), ",payload: ", notification.Payload)
res, err := client.Push(notification)
    .........

}

the variable client *apns.Client is global.

Error:net/http: Client Transport of type *http2.Transport doesn't support CancelRequest; Timeout not supported

run demo, throw error:

1. go version go1.5.4 darwin/amd64
2. macOS 10.12.1

go 1.6

when do apns2 support golang 1.6 ？

Thoughts on possible ClientConnPool

Unless I'm misunderstanding something, it would make sense to provide a client pool for APNS connections. It would be helpful for those who use this lib with multiple certificates.

My understanding is the ClientConnPool in the http2 libs cannot be used because the underlying Transport is used across all clients in the pool. That wouldn't work for this lib, as the TLS connection is configured with the Apple certificate for each client's transport.

If this is deemed a good idea and a possibility, I'd be willing to start a PR.

Why I don't get notification when apns2 sends notification successfuly.

hello, i am trying to get notification on my ios app,
apns2 is working fine like this. but my app is not getting notification.

2016/11/27 13:00:12 APNs ID: BA5AED23-31F3-77A6-9E8E-C9C0274ACEE0

of course, I did all things correctly on app side.
I checked my app with other php sample. this is php sample(apns not apns2) url link.
https://www.raywenderlich.com/123862/push-notifications-tutorial

You use
HostDevelopment = "https://api.development.push.apple.com"
HostProduction = "https://api.push.apple.com"

But he uses (php sample)
ssl://gateway.sandbox.push.apple.com:2195

How will I do?
My golang version is 1.7.3
cert.pem is Apple Developer IOS Push Services cert file.
OS: windows 10

Missing Reason consts

Comparing to current https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/CommunicatingwithAPNs.html#//apple_ref/doc/uid/TP40008194-CH11-SW1 these are missing (probably only first is valid for this package):

Client.Timeout exceeded while awaiting headers

in my program, i made 1000 goroutines for concurrency send msg to apple; when i check my log, i find a lot of error returns when i call client.Push, the error is "net/http: request canceled (Client.Timeout exceeded while awaiting headers)"; the timeout setting of the client is 10s:client.HTTPClient.Timeout = time.Duration(10) * time.Second;
i have no idea why this happened, is the timeout setting too short?

Safe for use from concurrent goroutines?

Is the client safe for use from concurrent goroutines?

When the TLS connection was builded?

I write my push operation according with the demo in ReadMe.md, but i am confused with the follwings:

client := apns2.NewClient(cert)
...
res, err := client.Push(notification)

so, when the connection was builded? when the DialTLS (client.HTTPClient.Transport.(*http2.Transport).DialTLS("tcp", "127.0.0:1", nil)) was called ?

Pushkit support?

Hi, I saw in README that this library support Pushkit, but I cannot find the implementation as well as the base url of gateway.push.apple.com for Pushkit send notification. Is there any example or explanation regarding the pushkit implementation?

Production()/Development() is not thread-safe (and more generally ClientManager will have inconsistent results if switching between Development/Production)

1. go version go1.8.3
2. darwin/amd64
3. Called client.Production() / client.Development() on clients return from ClientManager.Get
4. Expected no data race
5. Had "data race detected" from a test, between the line in my code calling client.Production() and apns2/client.go:156 (url := fmt.Sprintf("%v/3/device/%v", c.Host, n.DeviceToken))

Support for testing with a mock apn server

It would be great to support testing with a mock apn server that does not use ssl.

Incorrect thread-id implementation

As @jchambers picked up here #41, the APNs thread-id should be part of the payload and not a header as currently implemented.

apns2 occasionally doesn't send any requests to apple

I have a daemon process that just forwards push notifications to apple using apns2.

A handful of times when the process has started no push notifications were sent to apple. Restarting the apns2 daemon process fixes this. The contents of the apns2 successful and unsuccessful requests are exactly the same.

During the time when delivery of these push notifications failed the devices receive other push notifications. Also during this time the devices are able to directly communicate with the host that the apns2 daemon is running on.

Is there any way to enable detailed trace logging of apns2's http2 communications? For example, was it able to tcp connect, negotiate ssl, or actually send the http request?

Is there any way to enable timeouts of its requests or connection attempts?

it response stautscode=200, means push successful. but my iphone can't received

hi.
when I use it push message to apple's push server, it response stautscode=200, means push successed. but sometings my iphone can't received the push message.
why not 100% received push message by iphone. it's normal or is bug.

it,s my logs.

apns push performance

Hi，when i execute this code(res, err := client.Push(notification)), it cost about 1~3 seconds. but i want push more(probably push 1000 per second). how can i improve the performance. Thanks

certificate.FromPem* cannot parse PKCS#8 format

What did you do?

func main() {
  apnsCert, err := certificate.FromPemFile(os.Args[1], "")

  }
}

What did you expect to see?

A parsed certificate.

What did you see instead?

$ go run main.go testcertificate.pem
Error parsing private key asn1: structure error: tags don't match (2 vs {class:0 tag:16 length:13 isCompound:true}) {optional:false explicit:false application:false defaultValue:<nil> tag:<nil> stringType:0 timeType:0 set:false omitEmpty:false}  @5

What version of Go are you using?

$ go version

Notes

I opened a Stack Overflow question attempting to resolve this. The issue appears to be that sideshow/apns2/certificate assumes the private key to be in PKCS#1 format, whereas openssl pkcs12 generates a file with a private key in PKCS#8 format. I suggest that this lib should be able to parse PKCS#8 format, too.

A possible file descriptor leak in ClientManager?

Please ensure that you are using the latest version of the master branch before filing an issue.

Also make sure to include logs (if applicable) to help reproduce the issue by setting the GODEBUG=http2debug=2 env var.

1. What version of Go are you using? go version
   1.9.2

2. What OS and processor architecture are you using? go env
   linux amd64

3. What did you do?
   Here's my code simulate the situation which reach the MaxAge:

cert, _ := certificate.FromPemFile("cert.pem", "")
manager := apns2.NewClientManager()
manager.MaxAge = time.Second * 5
for {
    resp, err := manager.Get(cert).Production().Push(&apns2.Notification{Topic: apnsTopic, DeviceToken: deviceToken, Payload: payload})
    fmt.Println(resp, err)
    time.Sleep(time.Second * 6)
}

4. What did you expect to see?
   ClientManager create a new client, and the underlying connections of old client should be closed by GC or call client.CloseIdleConnections().

5. What did you see instead?
   netstat and lsof shows that number of open connections keep increasing.

Maybe ClientManager should close idle connections on removing old client?
If do this so, what if another goroutine using the same client while we call client.CloseIdleConnections()?

Add a better connection pool

The default golang http2 connection pool is good but lacks some important features which would be useful for the apns2 library:

• There is currently no way to have a minimum amount of TLS connections open (throughput)
• There is currently no way to have a maximum amount of TLS connections open (avoids exhausing resources). Similarly there is no way to control when connections are opened or closed.
• Connections are currently not opened until the first request is sent - There is currently no way to connect before the first push is sent.
• There is no visibility/stats into how many tcp connections and requests are currently active.
• There is no ability to control pings an keep connections alive from the pool - See issues #19, #45, #51

Ideally we want to write a custom connection pool to address the above issues. It should have reasonable defaults so that no configuration is needed out of the box, but provide the correct settings to customize for those that are using apns2 at scale.

How can I prevent this error?

c.HTTPClient.Do (in c.Push) hanging intermittently

As a preface, I'm reporting this to open a dialog. I think the ultimate problem will be with something I'm doing or a bug deep within the http2 libs of Go.

I've noticed that occasionally the call to c.HTTPClient.Do hangs indefinitely. The problem occurs intermittently and seemingly not because of the certificate used in the connection. Given enough retries (where the connection is remade by making a new handle on apns2.Client), it will succeed without error.

I'm not convinced this is a network issue. It seems something is deadlocking within the http2 libs. I set c.HTTPClient.Timeout to 1 second, which never triggers. Additionally I spin up a timeout goroutine of 3 seconds, which is how I determine that something is hanging, and at which point I attempt a retry. (As a side note, I just realized this may not cleanly kill the connection. Perhaps I should call CloseIdleConnections on the http2 transport?) It doesn't seem to be a network issue. Despite setting GODEBUG=http2debug=2, no http2 logs are outputted.

My sender is massively concurrent, having thousands of goroutines at any moment, but my interpretation is that if it gets to c.HTTPClient.Do, which is documented to be thread-safe, and then hangs, then there is a problem within the http2 libs.

Am I weirdly running out of possible connections or something? Does anyone have thoughts on this?

Missing feedback channel

Is there any feedback channel support for push notification ?

Apple voip push support?

Hi,

Is this library support apple voip push? If yes, can you provide us example how to send this kind of notification?

Thanks !

About apns2 notification's feedback ?

hi, when ios app is reinstalled and device token is changed . but client.Push() push old‘s device token returned 200 status code ? thanks.

Are there plans to add the newly released Token Authentication to the library? If there is work already in progress, when can we expect it to be merged into master and if not, will a PR be welcome?

http2 transport errors

Hi,

Setup as per your readme, substituting notification.DeviceToken and notification.Topic for my own.

I'm getting the following error:

ClientManager for token-based clients?

ClientManager is a great class, it would be nice to have a version of this class (TokenClientManager?) which works for JWT/Auth token based clients. It looks like this could be done without too much effort (make the Get method take a *token.Token, change cacheKey to be based on *token.Token instead of tls.Certificate, make Factory take a *token.Token instead of a tls.Certificate).

Beginner question - how to install and run (Win)

Please ensure that you are using the latest version of the master branch before filing an issue.

Also make sure to include logs (if applicable) to help reproduce the issue by setting the GODEBUG=http2debug=2 env var.

1. What version of Go are you using? go version
   go version go1.8.3 windows/amd64

2. What OS and processor architecture are you using? go env
   windows amd64

3. What did you do?

$ go get github.com/sideshow/apns2/apns2

$ apns2 --help
bash: apns2: command not found

4. What did you expect to see?
   apns2 help section

5. What did you see instead?
   apns2 not found.

First time using go. I expected that go get <> would install package and would add executable to path.

Update

I have found that C:\Users\<myUser>\go\bin contains the apns2.exe. I have added this to the path, and its working

$ apns2

Can I send multi-request on one apns client without any lock？

I was argueing with my colleague wheather I can write code like that

client = apns.NewClient(...)

Can I send push req without lock?
where is the mechanism that make sure the validation of http2 frame on that tcp connection? i am looking for details but haven't got yet

Document ClientManager and concurrent access safety

Can clients be used from multiple goroutines?

Is it recommended to keep an instance of client laying around or just create a new one per batch?

Add more example code and docs

• Document common APNs gotchas and errors (dev/prod gateway etc)
• Examples of how to use with go channels and go routines
• Document Client timeout behaviour (issue #24)
• Document ClientManager and concurrent access safety (issue #44)
• Document Generating correct .pem/p12 certificates (issue #33 and issue #46)

iOS 10 features not supported - e.g. thread-id on aps dictionary.

In payload/builder.go:

type aps struct {
        ...
    ThreadID   string         `json:"thread-id,omitempty"`
}

func (p *Payload) ThreadID(id threadID) *Payload {

How to use proxy server for send apple push notification..

We can send android push notification through proxy using following

transport := &http.Transport{Proxy: http.ProxyURL(proxyUrl)}
client := &http.Client{Transport: transport}
sender := &gcm.Sender{ApiKey: viper.GetString("pushNotification.gcmAPIKey"),Http:client}

but apns2 is using http2 and http2 transport doesn't have any way to set the proxyUrl.

Is it possible to send apple push notification through proxy server?

APNs invalid certificate yields (confusing) connection error

When you try to send data with an invalid certificate, you get this error:

Post https://api.push.apple.com/3/device/_token_goes_here_: http2: Transport: peer server initiated graceful shutdown after some of Request.Body was written; define Request.GetBody to avoid this error

This makes it look like a connection or implementation issue, while it is not.

When looking at the http2 logs, you can see that the gateway is explicitly telling you why they are cutting connection, the certificate is wrong: APNsConnectionCut.txt. The interesting part is: http2: Transport received GOAWAY len=46 LastStreamID=0 ErrCode=NO_ERROR Debug="{"reason":"BadCertificateEnvironment"}"
While it would have been nice from the Gateway to use the usual status error code to tell that the certificate is wrong, it does not. If there is an easy way to read GOAWAY frames to return an error that includes the eventual Debug field from Transport, it would be great to use it. If not, you may archive this report.

1. Version: go1.7.4
2. Env: running on darwin/amd64, same issue with a static binary on linux
3. How-To-Reproduce: posting one silent push notification with an invalid certificate (observed on prod gateway)
4. Observed: client.Push returns a connection/implementation error.
5. Expected: client.Push returns a error that includes the Debug field of the associated Transport when available.

Loading .p12 certificate: ans1: indefinite length found (not DER)

Hello,

I am trying to use the apns2 module but when I try to load the p12 file I get the following error

ans1: indefinite length found (not DER)

I was able to convert the file to .pem using the command line openssl, and it worked but this is not an ideal solution, I need to be able to use the p12 file directly or convert it to pem at runtime. Sadly the openssl bindings do not offer this functionality as of now. Any suggestions?

Can not understand how to generate acceptable pem cert

Hello. Thank you for the lib.

I use this command to convert p12 cer to pem

openssl pkcs12 -in aps.p12 -out aps.pem -nodes -clcerts

Which is works fine when i test it with ruby houston gem.

To test this lib i just use example code from readme, only path to the pem file is changed.

The result is error message

Cert Error:failed to parse PKCS1 private key

Which is referenced to apns2/certificate/certificate.go from this lib.

When it fail i tried to send passphrase as the last param into certificate.FromPemFile without success.

My questions are:

• What is the correct way to generate p12 for this library?
• Why same cert works with ruby lib and dose not with current one?

Thanks in advance.

When i say works fine i mean push notifications are delivered to destination device.

url.Error "unexpected EOF"

apns2 has been working great in production, for the most part. However, occasionally, I see inexplicable "unexpected EOF" errors. The error is a &url.Error{Op:"Post", URL:"https://api.push.apple.com/3/device/<omitted>", Err:(*errors.errorString)(0xc82000a150)}, where the Err property of the url error is "unexpected EOF". The error is not a temporary url.Error, so I assumed it may be an issue with my apns2.Client's connection, which I am keeping open. So when I encounter the error, I remake the client (thus remaking the connection), but the error continues to happen (makes sense, it's a permanent error). I'm just not sure what it could be, exactly.

Any ideas for what this means or how I could debug?

how to check health of the connection?

when i create a new client，how can i check health of it ?
In Apple Privider Api Doc, it said: "You can check the health of your connection using an HTTP/2 PING frame." In your "Push" fuction, you said:
"If the underlying http.Client is not currently connected, this method will attempt to reconnect transparently before sending the notification."
so, did i need do something else to keep alive of the connetion?

Did anyone test the jwt-token-example ? I got "InvalidProviderToken" error

https://github.com/sideshow/apns2#jwt-token-example

my code

func Push2User() {

	authKey, err := token.AuthKeyFromFile("/root/xxxxx/AuthKey_6737ABXXXX.p8")
	if err != nil {
		log.Fatal("token error:", err)
	}

	token := &token.Token{
		AuthKey: authKey,
		KeyID:   "6737ABXXXX",
		TeamID:  "MNLVE7XXXX",
	}

	notification := &apns2.Notification{}
	notification.DeviceToken = "80F3C8FAF0DC85144D192075D2A884FAACC9492A219C90C6CF6FB7460128A7E0"
	notification.Topic = "com.xxxx.xxxx.io"

	payload := payload.NewPayload().Alert("Hello World").Badge(1).Custom("url", "http://xxxx.co")
	notification.Payload = payload

	log.Println(notification)

	// client := apns2.NewTokenClient(token).Production()

	log.Println(token)
	client := apns2.NewTokenClient(token).Development()
	res, err := client.Push(notification)

	if err != nil {
		log.Fatal("Error:", err)
	}

	fmt.Printf("%v %v %v\n", res.StatusCode, res.ApnsID, res.Reason)
}

iOS 10: Notification Mutable?

iOS 10 Adds another key you can set on the payload, mutable-content which can be set to 0 or 1 based on if you wish to intercept the payload and mutate or replace it before the user sees it.

Will need to expand apsn2 to include that and make sure it's support via CLI and payload builder.

I'll put in a PR for this, to follow in the next few days.
