I'm trying to use Postman to create and test Apple Notifications in my iOS app.
For a reason I don't get, requests I send from Postman to either https://api.development.push.apple.com/3/device/<token-device> or https://api.push.apple.com/3/device/<token-device> fail without getting any HTTP response.
What I've done so far:
1 - created and exported a APNS certificate from my developer.apple.com account (as explained there).
2 - converted this .p12 certificate with a recent version of openssl (1.0.2l) to a .pem cert and key like this:
openssl pkcs12 -in apns.p12 -out apns.crt.pem -clcerts -nokeys
openssl pkcs12 -in apns.p12 -out apns.key.pem -nocerts -nodes
3 - configured Postman (Preferences > certificates) to use these .pem files for both Provider API urls (dev and prod)
4 - setup a POST request to those Provider API endpoint for my device token with a apns-topic header that has my bundle id for value, and a HTTP body like this:
{
"aps" : {
"alert" : {
"title" : "Game Request",
"body" : "Bob wants to play poker"
}
}
}
It fails with "Could not get any response, blablabla".
If I check what happens it the Postman console, I see:
POST https://api.development.push.apple.com/3/device/12340e529f85a145b567736e7fd84c9d7e42a43a3c343ec378c2ff071011e4 06:18:08.236
Error: Parse Error
Client Certificate:

pemPath:"/Users/thomas/wksp_myproj/apns.crt.pem"

Postman-Token:"99615df2-b2aa-4a51-8d15-8ce27f4e8ca9"

Also, when I test with openssl as explained there:
openssl s_client -connect api.development.push.apple.com:443 -cert apns.pem -debug -showcerts -CAfile GeoTrust_Global_CA.pem
I get a lot of outputs with at the end:
HTTP/2 client preface string missing or corrupt. Hex dump for received bytes: 0aread from 0x7f9445c215c0 [0x7f9446015c03] (5 bytes => 0 (0x0))

What's going wrong?
