erlang -- ios apns provider -- erlang 实现

os apns-apple notification server 与第三方provider的通信原理网上已有很多介绍,这里不再介绍,有想了解的大家可以去IOS官网https://developer.apple.com/library/ios/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/Chapters/ApplePushService.html#//apple_ref/doc/uid/TP40008194-CH100-SW1

学习了解.

网上关于IOS apns自己实现的很少,一般是Java或者PHP，目前还有一个用C++实现的,看了看,然后自己想用erlang实现与IOS apns的通信,进过努力实现了,与大家分享.

-define(URL,"gateway.sandbox.push.apple.com").

-define(PORT,2195).

-define(DEVICE_TOKEN,"3bd9dbf509cd92d41a3334d8ab0fcced1a6fc27c7c1bc60324b2bafe1c15cadf").

start() ->

ssl:start(),

case gen_tcp:connect(?URL,?PORT,[binary],infinity) of

{ok,Socket} ->

case ssl:connect(Socket,[{certfile,"./ios_app/PushChatCert.pem"},

{keyfile,"./ios_app/PushChatKey.pem"},

{password,"123456"}],

infinity) of

{ok,SslSocket} ->

io:format("####socket connect:~p~n",["ok"]),

Command = <<0:8>>,

Token = ?DEVICE_TOKEN,

DeviceList = change_16_to_10(Token,[]),

Device = list_to_binary(DeviceList),

io:format("##Device:~p~n",[Device]),

DeviceL = length(DeviceList),

DeviceBin = <<DeviceL:16>>,

Message = "{\"aps\":{\"alert\":\"哈哈我的测试\",\"badge\":4,\"sound\":\"default\"}}",

MessageL = length(Message),

MessageBin = <<MessageL:16>>,

Data = list_to_binary([Command,DeviceBin,Device,MessageBin,Message]),

case ssl:send(SslSocket,Data) of

ok ->

io:format("######send ok!~n");

{error,SReason} ->

io:format("####SReason:send error:~p~n",[SReason])

end;

{error,Reason} ->

io:format("####Reason:~p~n",[Reason])

end;

{error,FRe} ->

io:format("#FRe:~p~n",[FRe])

end.

 

 

change_16_to_10([],L) ->

lists:reverse(L);

change_16_to_10([H,T|Tail],L) ->

First = assci_to_10_type(H),

Second = assci_to_10_type(T),

One = First * 16 + Second,

change_16_to_10(Tail,[One|L]).

 

 

assci_to_10_type(Term) when Term >= $a andalso Term =< $f ->

Term - $a + 10;

assci_to_10_type(Term) when Term >= $A,Term =< $F ->

Term - $A + 10;

assci_to_10_type(Term) when Term >= $0,Term =< $9 ->

Term - $0;

assci_to_10_type(_Term) ->

0.

 

与苹果apns通信的证书怎么来的？参考IOS官方文档.

简单介绍:需要iOS开发者提供给服务端的开发者aps_production.cer从苹果开发者网站下载;

然后在终端中输入下面命令

openssl x509 -in aps_production.cer -inform der -out PushChatCert.pem

得到PushChatCert.pem

双击安装aps_production.cer到钥匙串,在钥匙串中找到刚才安装的推送证书,点开,右键导出秘要,命名为youkey.p12;demo中是PushChatKey.p12

然后在终端中输入下面命令

openssl pkcs12 -nocerts -out PushChatKey.pem -in  PushChatKey.p12

此处需要输入密码,demo中的密码:123456

重复确认密码，得到PushChatKey.pem
