 2 | ==============
 3 | 
 4 | A quick and dirty script to mock the new HTTP/2 interface to Apple's push gateway.
 5 | Most requests to this server will return a successful response, however, some of
 6 | them will return a "BadDeviceToken" or an "Unregistered" from time to time.
 7 | 
 8 | # Usage
 9 | ```
10 |   -cert string
11 |     	The path to the certificate (default "cert.pem")
12 |   -key string
13 |     	The path to the certificate key (default "key.pem")
14 |   -port int
15 |     	The port for the mock server to listen to (default 8443)
16 | ```
17 | 
18 | # Getting started
19 | ### Install the Go programming language
20 | See [here](https://golang.org/doc/install). Be sure to install at least version 1.6.
21 | 
22 | ### Generate your self signed certificate
23 | Create a self signed certificate using one of Go's scripts:
24 | ```
25 | $ go run /usr/local/go/src/crypto/tls/generate_cert.go --host clevertap.com
26 | ```
27 | 
28 | ### Start the server
29 | If you created the certificate elsewhere, you'll need to use the
30 | options -cert and -key to specify where the certificate and its key are located.
31 | ```
32 | $ go build go-apns-server.go
33 | $ ./go-apns-server
34 | ```
35 | 
36 | The default port is 8443, which can be changed by passing the -port argument
