苹果远程推送实现笔记（iOS）_app

1.准备工作（developer.apple.com里面完成）

前提有开发证书ios-dev.cer(iOS Development) 发布用到证书ios-dist.cer(iOS Distribution)

在Identifiers页面点+，添加bundle ID ，例如“com.xxx.yyy”,在配置页面下拉到Push Notifications，勾上，然后右边看到edit链接，点edit会d窗，提示添加证书（用keychain生成一份push. certSigningRequest）,相应导入certSigningRequest文件，这样就可以得到两个证书aps_development.cer（开发用到）和aps.cer（发布用到）

在Profiles页面点+，生成两份配置 push-dev（开发）和push-appstore（发布）其中的identify就选上面那个“com.xxx.yyy”对应的项

在Keys页面点+，随便填个名字，勾选“Apple Push Notifications service (APNs)”,点continue，然后下载保存好，文件名暂定叫push.p8 里面也有一个key ID 假设是“SP12345678”

2. Xcode代码

在AppDelegate.m中加入

#import

在- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions方法里面注册通知

[UIApplication sharedApplication].applicationIconBadgeNumber=0;
  /*
   identifier：行为标识符，用于调用代理方法时识别是哪种行为。
   title：行为名称。
   uiusernotificationactivationmode：即行为是否打开app。
   authenticationrequired：是否需要解锁。
   destructive：这个决定按钮显示颜色，yes的话按钮会是红色。
   behavior：点击按钮文字输入，是否d出键盘
   */
  
  UNNotificationAction *action1 = [UNNotificationAction actionWithIdentifier:@"action1" title:@"foreground action" options:UNNotificationActionOptionForeground];
  UNNotificationAction *action2 = [UNNotificationAction actionWithIdentifier:@"action2" title:@"authentication required" options:UNNotificationActionOptionAuthenticationRequired];
  
  UNNotificationCategory *category1 = [UNNotificationCategory categoryWithIdentifier:@"category1" actions:@[action2,action1] intentIdentifiers:@[@"action1",@"action2"] options:UNNotificationCategoryOptionCustomDismissAction];
    
  [[UNUserNotificationCenter currentNotificationCenter] setNotificationCategories:[NSSet setWithObjects:category1, nil]];
  [[UNUserNotificationCenter currentNotificationCenter] requestAuthorizationWithOptions:UNAuthorizationOptionBadge|UNAuthorizationOptionSound|UNAuthorizationOptionAlert completionHandler:^(BOOL granted, NSError * _Nullable error) {
    NSLog(@"completionhandler");
  }];
  
    
  [[UIApplication sharedApplication] registerForRemoteNotifications];
  
  [UNUserNotificationCenter currentNotificationCenter].delegate = self;

再添加两个相应函数：

- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *) error {
    NSLog(@"Registfail%@",error);
}
-(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken{
    NSLog(@"%@",deviceToken);//这里的Token就是我们设备要告诉服务端的Token码，
		unsigned char buffer[1024]={0};
		NSMutableString *mstr = [NSMutableString string];
  for (int i=0; i

 
 
3. PHP服务器实现： 
https://api.sandbox.push.apple.com/3/device/{device-token}  ||dev 开发 
https://api.push.apple.com/3/device/{device-token}   || pub 发布 
添加 header: 
content-type: application/json
apns-topic: com.wancaiinfo.yunzhan365app
apns-priority: 10
apns-push-type: alert
authorization: bearer $jwt 
   //badge = 6;   //显示在icon里面的数值 
body: 
{“aps":{"alert":{"title":"title test","body":"content test"},"badge":6,"sound":"default"}} 
 
其中$jwt = $header.$claims.$signCode 
 
$header=Base64('{ "alg": "ES256", "kid": "SP12345678(上面提到的key ID)” }') 结果要替换+为-，/为_;   暂时定义这个函数名JWTBASE64。 
 
$claims = JWTBASE64('{ "iss": “(teamId 开发组ID，自己developer.apple.com上找)”, "iat": (时间戳)}’); 
 
$signCode= JWTBASE64(sign($header.$claims));  签名后的数据还是要JWTBASE64一把。 
 
sign签名函数可以使用JWT库做到，目前使用加密方法是ES256 
 
4.手动测试（将下面的代码改好，保存为push_test,运行 “chomd +x push_test”加运行权限） 
 
#!/bin/bash

# Get curl with HTTP/2 and openssl with ECDSA: 'brew install curl-openssl'
curl=/usr/bin/curl
openssl=/opt/local/bin/openssl

# --------------------------------------------------------------------------
deviceToken={这里填写在-(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken拿到的deviceToken字符串}

authKey="./push.p8"   #（p8文件）
authKeyId=SP12345678 #（key ID）
teamId=Sxxxxxxxxx  # (开发组ID)
bundleId=com.xxx.yyyy  #（Bundle ID）
#endpoint=https://api.development.push.apple.com
endpoint=https://api.sandbox.push.apple.com

read -r -d '' payload <<-'EOF'
{
   "aps": {
      "alert": {
         "title": " test for title",
         "body": "testing ...."
      }
   }
}
EOF

# --------------------------------------------------------------------------

base64() {
   $openssl base64 -e -A | tr -- '+/' '-_' | tr -d =
}

sign() {
   printf ""| $openssl dgst -binary -sha256 -sign "$authKey" | base64
}

time=$(date +%s)
header=$(printf '{ "alg": "ES256", "kid": "%s" }' "$authKeyId" | base64)
claims=$(printf '{ "iss": "%s", "iat": %d }' "$teamId" "$time" | base64)
jwt="$header.$claims.$(sign $header.$claims)"

$curl --verbose \
   --header "content-type: application/json" \
   --header "authorization: bearer $jwt" \
   --header "apns-topic: $bundleId" \
   --header "apns-push-type: alert" \
   --data "$payload" \
   $endpoint/3/device/$deviceToken
 
//----------------后续----------------- 
在真机测试是遇到 
You've implemented -[ application:didReceiveRemoteNotification:fetchCompletionHandler:], but you still need to add "remote-notification" to the list of your supported UIBackgroundModes in your Info.plist. 
这个应该是要在项目工程里面"Signing &Capabilities"点+右边的“Capability”,选择“Background Modes”,然后勾上"Remote notifications".
