利用voip push實(shí)現(xiàn)類似微信(QQ)電話連續(xù)響鈴效果

前言

本文大部分參考 iOS利用voip push實(shí)現(xiàn)類似微信(QQ)電話連續(xù)響鈴效果 有興趣的可以多參考它下
自己代碼：gitHubDemo

最近客戶要求需要做出類似微信的 視頻拉起的呼叫的功能，開始使用的是mqtt的方式來(lái)發(fā)起的消息拉起，

結(jié)果：發(fā)現(xiàn) app退到后臺(tái)、或者app殺死了，就不會(huì)收到了（也就拉起不了了）

試了：APNs的方式,結(jié)果APNs根本實(shí)現(xiàn)不了連續(xù)通知，而且它也不會(huì)實(shí)現(xiàn)像本地通知那樣會(huì)有連續(xù)響鈴的效果（微信一般大概30s左右）

為了實(shí)現(xiàn)類似微信的方式，最終：我們通過(guò) voip的方式來(lái)實(shí)現(xiàn)app的視頻的拉起

  • 說(shuō)明

    • VoIP 推送基于pushKit框架
    • 好處：
      • 只有當(dāng)VoIP發(fā)生推送時(shí)，設(shè)備才會(huì)喚醒，從而節(jié)省能源。
      • VoIP推送被認(rèn)為是高優(yōu)先級(jí)通知，并且毫無(wú)延遲地傳送。
      • VoIP推送可以包括比標(biāo)準(zhǔn)推送通知提供的數(shù)據(jù)更多的數(shù)據(jù)。
      • 如果收到VoIP推送時(shí)，您的應(yīng)用程序未運(yùn)行，則會(huì)自動(dòng)重新啟動(dòng)。
      • 即使您的應(yīng)用在后臺(tái)運(yùn)行，您的應(yīng)用也會(huì)在運(yùn)行時(shí)處理推送。

  • voip的集成

    • 在Xcode中開啟VoIP推送
    voip_01.jpeg

  • 在Apple Developer創(chuàng)建VoIP證書


    voip_02.jpeg

  • 跟APNs證書不同，VoIP證書不區(qū)分開發(fā)和生產(chǎn)環(huán)境，VoIP證書只有一個(gè)，生產(chǎn)和開發(fā)都可用同一個(gè)證書。另外有自己做過(guò)推送的應(yīng)該都知道服務(wù)器一般集成的.pem格式的證書，所以還需將證書轉(zhuǎn)成.pem格式，后面會(huì)介紹怎么轉(zhuǎn)換.pem證書。
    導(dǎo)入framework:PushKit.framework

  • Objective-C代碼集成，導(dǎo)入頭文件.

    #import <PushKit/PushKit.h>

  • 設(shè)置代理

    PKPushRegistry *pushRegistry = [[PKPushRegistry alloc] initWithQueue:dispatch_get_main_queue()];
pushRegistry.delegate = self;
pushRegistry.desiredPushTypes = [NSSet setWithObject:PKPushTypeVoIP];

  • 代理方法

    //應(yīng)用啟動(dòng)此代理方法會(huì)返回設(shè)備Token 、一般在此將token上傳服務(wù)器
- (void)pushRegistry:(PKPushRegistry *)registry didUpdatePushCredentials:(PKPushCredentials *)credentials forType:(NSString *)type{
}

//當(dāng)VoIP推送過(guò)來(lái)會(huì)調(diào)用此方法，一般在這里調(diào)起本地通知實(shí)現(xiàn)連續(xù)響鈴、接收視頻呼叫請(qǐng)求等操作

使用：
在appdelegate.m里面
導(dǎo)入 #import "TalkVideoManager.h"

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {  
  ......
    //配置voIP
    [[TalkVideoManager sharedClient] initWithSever];
    return YES;
}

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{
   NSLog(@"點(diǎn)擊了本地通知進(jìn)來(lái)了---%@",notification.userInfo);
   [[TalkVideoManager sharedClient] cancleCall];
   
   .......//處理數(shù)據(jù)
}

說(shuō)白了：就是通過(guò)voip發(fā)的消息回調(diào)，來(lái)進(jìn)行發(fā)送本地通知，然后點(diǎn)擊本地通知，再做相應(yīng)的數(shù)據(jù)邏輯處理。

  • 建立本地測(cè)試環(huán)境(自己搭建一個(gè)簡(jiǎn)單的測(cè)試環(huán)境先測(cè)試通，然后再與服務(wù)器對(duì)接)

    • 制作.pem格式證書

      1、將之前生成的voip.cer SSL證書雙擊導(dǎo)入鑰匙串
2、打開鑰匙串訪問(wèn)，在證書中找到對(duì)應(yīng)voip.cer生成的證書，右鍵導(dǎo)出并選擇.p12格式,這里我們命名為voippush.p12,這里導(dǎo)出需要輸入密碼(隨意輸入，別忘記了)。
3、目前我們有兩個(gè)文件，voip.cer SSL證書和voippush.p12私鑰，新建文件夾命名為VoIP、并保存兩個(gè)文件到VoIP文件夾。
4、把.cer的SSL證書轉(zhuǎn)換為.pem文件，打開終端命令行cd到VoIP文件夾、執(zhí)行以下命令
openssl x509 -in voip.cer  -inform der -out VoiPCert.pem
5、把.p12私鑰轉(zhuǎn)換成.pem文件，執(zhí)行以下命令（這里需要輸入之前導(dǎo)出設(shè)置的密碼）
openssl pkcs12 -nocerts -out VoIPKey.pem -in voippush.p12
6、再把生成的兩個(gè).pem整合到一個(gè).pem文件中
cat VoiPCert.pem VoIPKey.pem > ck.pem
最終生成的ck.pem文件一般就是服務(wù)器用來(lái)推送的。

    • 新建php文件（保存名字為push.php）

      <?php

// Put your device token here (without spaces):
$deviceToken = '這里填寫手機(jī)注冊(cè)的devideToken';
    
$passphrase = '這里填寫導(dǎo)出p12文件的密碼';

// Put your alert message here:
$message = '要推送的內(nèi)容';
$info =  array("id"=>"1","address"=>"IANA"); //自己寫的一個(gè)info字典（自己后臺(tái)可以自定義）

////////////////////////////////////////////////////////////////////////////////

$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', 'ck.pem'); //這里的ck.pem需要和導(dǎo)出的證書名字要一致
stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);
stream_context_set_option($ctx, 'ssl', 'verify_peer', false);

// Open a connection to the APNS server
//ssl://gateway.sandbox.push.apple.com:2195（測(cè)試環(huán)境）
//ssl://gateway.push.apple.com:2195（生產(chǎn)環(huán)境）
$fp = stream_socket_client('ssl://gateway.sandbox.push.apple.com:2195', $err,$errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);

if (!$fp)
    exit("Failed to connect: $err $errstr" . PHP_EOL);

echo 'Connected to APNS' . PHP_EOL;

// Create the payload body
$body['aps'] = array(
    'content-available' => '1',
    'alert' => $message,
    'sound' => 'weixin.m4a',
    'badge' => 0,
    'info'=> $info,
    );

// Encode the payload as JSON
$payload = json_encode($body);

// Build the binary notification
$msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload)) . $payload;

// Send it to the server
$result = fwrite($fp, $msg, strlen($msg));

if (!$result)
    echo 'Message not delivered' . PHP_EOL;
else
    echo 'Message successfully delivered' . PHP_EOL;

// Close the connection to the server
fclose($fp);   
?>

    • 推送測(cè)試

      • 將ck.pem 文件和push.php 放在同一個(gè)文件夾下（必須）

      • 一般測(cè)試VoIP推送的穩(wěn)定性最好是通過(guò)Hoc證書打包在生產(chǎn)環(huán)境中測(cè)試

      • 打開terminal ，cd到 push.php 文件目錄下

      • 輸入：php push.php (不出意外就可以收到推送啦)

        voip_03.png

  • 補(bǔ)充點(diǎn)（摘錄 iOS利用voip push實(shí)現(xiàn)類似微信(QQ)電話連續(xù)響鈴效果）

    • 當(dāng)app要上傳App Store時(shí)，請(qǐng)?jiān)趇Tunes connect上傳頁(yè)面右下角備注中填寫你用到VoIP推送的原因，附加上音視頻呼叫用到VoIP推送功能的demo演示鏈接，演示demo必須提供呼出和呼入功能，demo我一般上傳到優(yōu)酷。
    • 經(jīng)過(guò)大量測(cè)試，VoIP當(dāng)應(yīng)用被殺死（雙擊劃掉）并且黑屏大部分情況都能收到推送，很小的情況會(huì)收不到推送消息，經(jīng)測(cè)試可能跟手機(jī)電量消耗還有信號(hào)強(qiáng)弱有關(guān)。 再?gòu)?qiáng)調(diào)一遍，測(cè)試穩(wěn)定性請(qǐng)?jiān)谏a(chǎn)環(huán)境測(cè)試。
