通過本教程，你將學會如何用PHP創建一個機器人APP,讓它能接受消息.
PHP 環境安裝:
本教程的程序基于PHP 7開發，所以你需要先安裝PHP7.2/PHP7.3與composer, 其中，composer是PHP的包管理系統!
on macOS
brew update
brew install php@7.2
php -r "copy("https://getcomposer.org/installer", "composer-setup.php");"
php -r "if (hash_file("sha384", "composer-setup.php") === "48e3236262b34d30969dca3c37281b3b4bbe3221bda826ac6a9a62d6444cdb0dcd0615698a5cbe587c3f0fe57a54d8f5") { echo "Installer verified"; } else { echo "Installer corrupt"; unlink("composer-setup.php"); } echo PHP_EOL;"
//將PHP安裝到/usr/local/opt/php@7.2/bin 目錄，并取一個簡單的各字：composer
php composer-setup.php --install-dir=/usr/local/opt/php@7.2/bin --filename=composer
php -r "unlink("composer-setup.php");"
如果之前你安裝過php 7.1 或者更舊的php版本，執行brew unlink php@7.1刪除這些鏈接，然后再執行brew link php@7.3將php 7.3鏈接到php.
wenewzha:mixin_labs-php-bot wenewzhang$ brew unlink php@7.1
Unlinking /usr/local/Cellar/php/7.1.23... 24 symlinks removed
wenewzha:mixin_labs-php-bot wenewzhang$ brew link php@7.3
Warning: php@7.3 is keg-only and must be linked with --force
If you need to have this software first in your PATH instead consider running:
echo "export PATH="/usr/local/opt/php@7.3/bin:$PATH"" >> ~/.bash_profile
echo "export PATH="/usr/local/opt/php@7.3/sbin:$PATH"" >> ~/.bash_profile
之后，根據你的系統實際情況，看看php -v能不能執行成功，如果不行，將默認的PATH設置并保存到.bash_profile.
echo "export PATH="/usr/local/opt/php@7.3/bin:$PATH"" >> ~/.bash_profile
echo "export PATH="/usr/local/opt/php@7.3/sbin:$PATH"" >> ~/.bash_profile
source ~/.bash_profile
on Ubuntu
apt update
apt upgrade
//install php 7.2
apt-get install software-properties-common python-software-properties
add-apt-repository -y ppa:ondrej/php
apt-get update
apt-get install php7.2 php7.2-cli php7.2-common
//install composer
php -r "copy("https://getcomposer.org/installer", "composer-setup.php");"
php -r "if (hash_file("sha384", "composer-setup.php") === "48e3236262b34d30969dca3c37281b3b4bbe3221bda826ac6a9a62d6444cdb0dcd0615698a5cbe587c3f0fe57a54d8f5") { echo "Installer verified"; } else { echo "Installer corrupt"; unlink("composer-setup.php"); } echo PHP_EOL;"
//將PHP安裝到/usr/local/opt/php@7.2/bin 目錄，并取一個簡單的各字：composer
php composer-setup.php --install-dir=/usr/local/bin --filename=composer
php -r "unlink("composer-setup.php");"
最新的Composer在這兒Composer
請確保PHP與composer安裝在$PATH包含的目錄之內，直接運行php -v 或 composer -V 就可以檢查出來，如果提示如下，表示安裝正確！
wenewzha:minecraft wenewzhang$ php -v
PHP 7.2.13 (cli) (built: Dec 7 2018 10:41:23) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies

wenewzha:minecraft wenewzhang$ composer -V
Composer version 1.8.0 2018-12-03 10:31:16
如果提示command not found,表示bash沒有在$PATH下找到php,請重復以上的安裝步驟！
wenewzha:mixin_network-nodejs-bot2 wenewzhang$ php -v
-bash: php: command not found
創建你的項目
到你的工作文檔中，創建一個目錄，并取一個名字，比如:mixin_labs-php-bot
mkdir mixin_labs-php-bot
cd mixin_labs-php-bot
轉到新創建的項目目錄下, 執行 composer init, 依提示完成 composer.json的創建,
root@iZj6cbmqen2lqp7l48nfgkZ:~/mixin_labs-php-bot# composer init
Welcome to the Composer config generator
This command will guide you through creating your composer.json config.

本教程引用了 mixin-sdk-php 與 Ratchet pawl, mixin-sdk-php 是一個Mixin Network PHP SDK , Ratchet pawl 是一個WebSocket客戶端.
打開composer.json, 在"require"增加兩行引用:
"require": {
"exinone/mixin-sdk-php": "^1.1",
"ratchet/pawl": "^0.3.3",
},
保存composer.json后，執行 composer install 來下載：
composer install
下載完成后，目錄下會出現一個vendor的子目錄。
root@iZj6cbmqen2lqp7l48nfgkZ:~/mixin_labs-php-bot# ls
composer.json composer.lock vendor
如果你是git克隆的源代碼，直接執行 composer install 來下載依賴包。
創建第一個機器人APP
按下面的提示，到mixin.one創建一個APPtutorial.
生成相應的參數
記下這些生成的參數
它們將用于config.php中.
在項目目錄下，創建config.php,將生成的參數，替換成你的！
config.php
return [
"mixin_id" => "7000101716",
"client_id" => "a1ce2967-a534-417d-bf12-c86571e4eefa",
"client_secret" => "7339866727d24eeec1c4ebb6c634fd25a7b9057ee6d5939cca9b6b9fc15f4d1f",
"pin" => "512772",
"pin_token" => "abRdNq6soRALRG434IgR7WS/qP7LOcpfviqSfWfABdIKyZGLnWXFMrVCHpChIkBRGRAcsUguni0OoNsShddPVL3qoD5fxbF5dRUiRv14urH1Pmdl6zIZdCH159QMr5wLmmSHSGu2AihNkUHUo3bAJsrvOW0nke5y6R5YE/pNNfo=",
"session_id" => "51faabbf-48ff-4df2-898d-e9b318afae35",
"private_key" => <<
需要替換的參數包括： mixin_id, client_id, client_secret, and the pin, pin token, session_id, private key.
經典的Hello world
在項目目錄下創建一個app.php文件，將下面的代碼拷進去：
15
]);
$connector = new RatchetClientConnector($loop,$reactConnector);
class callTraitClass {
use MixinSDKTrait;
public $config;
public function __construct()
{
$config = require(__DIR__."/config.php");
$this->config = $config;
}
}
$callTrait = new callTraitClass();
$Token = $callTrait->getToken("GET", "/", "");
// $connector("ws://127.0.0.1:9000", ["protocol" => "Mixin-Blaze-1"], ["Origin" => "http://localhost",
$connector("wss://blaze.mixin.one", ["protocol" => "Mixin-Blaze-1"],[
"Authorization" => "Bearer ".$Token
])
->then(function(RatchetClientWebSocket $conn) {
$conn->on("message", function(RatchetRFC6455MessagingMessageInterface $msg) use ($conn) {
$jsMsg = json_decode(gzdecode($msg));
print_r($jsMsg);
if ($jsMsg->action === "CREATE_MESSAGE" and property_exists($jsMsg,"data")) {
echo "
Need reply server a receipt!
";
$RspMsg = generateReceipt($jsMsg->data->message_id);
$msg = new Frame(gzencode(json_encode($RspMsg)),true,Frame::OP_BINARY);
$conn->send($msg);
if ($jsMsg->data->category === "PLAIN_TEXT") {
$msgData = sendPlainText($jsMsg->data->conversation_id,
base64_decode($jsMsg->data->data));
$msg = new Frame(gzencode(json_encode($msgData)),true,Frame::OP_BINARY);
$conn->send($msg);
} //end of PLAIN_TEXT
} //end of CREATE_MESSAGE
});
$conn->on("close", function($code = null, $reason = null) {
echo "Connection closed ({$code} - {$reason})
";
});
/* start listen for the incoming message */
$message = [
"id" => Uuid::uuid4()->toString(),
"action" => "LIST_PENDING_MESSAGES",
];
print_r(json_encode($message));
$msg = new Frame(gzencode(json_encode($message)),true,Frame::OP_BINARY);
$conn->send($msg);
// $conn->send(gzencode($msg,1,FORCE_DEFLATE));
}, function(Exception $e) use ($loop) {
echo "Could not connect: {$e->getMessage()}
";
$loop->stop();
});
$loop->run();
function sendPlainText($conversation_id,$msgContent):Array {
$msgParams = [
"conversation_id" => $conversation_id,
"category" => "PLAIN_TEXT",
"status" => "SENT",
"message_id" => Uuid::uuid4()->toString(),
"data" => base64_encode($msgContent),//base64_encode("hello!"),
];
$msgPayButton = [
"id" => Uuid::uuid4()->toString(),
"action" => "CREATE_MESSAGE",
"params" => $msgParams,
];
return $msgPayButton;
}
function generateReceipt($msgID):Array {
$IncomingMsg = ["message_id" => $msgID, "status" => "READ"];
$RspMsg = ["id" => Uuid::uuid4()->toString(), "action" => "ACKNOWLEDGE_MESSAGE_RECEIPT",
"params" => $IncomingMsg];
return $RspMsg;
}
保存，并在終端里執行app.php
php app.php
如果一切正常，提示如下：
wenewzha:mixin_labs-php-bot wenewzhang$ php app.php
a1ce2967-a534-417d-bf12-c86571e4eefa{"id":"4454b6c5-4a89-440c-bd22-7a79cf4954ca","action":"LIST_PENDING_MESSAGES"}stdClass Object
(
[id] => 4454b6c5-4a89-440c-bd22-7a79cf4954ca
[action] => LIST_PENDING_MESSAGES
)
在手機安裝 Mixin Messenger,增加機器人為好友,(比如這個機器人是7000101639) 然后發送消息給它,效果如下!
源代碼解釋
WebSocket是建立在TCP基礎之上的全雙工通訊方式，我們需要建立一個loop循環來維持通迅。
$loop = ReactEventLoopFactory::create();
$reactConnector = new ReactSocketConnector($loop, [
"timeout" => 15
]);
$connector = new RatchetClientConnector($loop,$reactConnector);
機器人APP通過Mixin Messenger服務器來接收用戶發過來的消息，連接服務器，需要Token來驗證用戶的身份,
詳細資料可參考如下鏈接:
Token認證, 接收服務器消息
mixin-sdk-php 實現了令牌Token的生成(getToken), 調用代碼如下：
class callTraitClass {
use MixinSDKTrait;
public $config;
public function __construct()
{
$config = require(__DIR__."/config.php");
$this->config = $config;
}
}
$callTrait = new callTraitClass();
$Token = $callTrait->getToken("GET", "/", "");
連接到服務器，注意協議類型與Token:
$connector("wss://blaze.mixin.one", ["protocol" => "Mixin-Blaze-1"],[
"Authorization" => "Bearer ".$Token
])
向服務器發送"LIST_PENDING_MESSAGES",這樣服務器才會將收到的消息發送給機器人APP.
/* start listen for the incoming message */
$message = [
"id" => Uuid::uuid4()->toString(),
"action" => "LIST_PENDING_MESSAGES",
];
print_r(json_encode($message));
$msg = new Frame(gzencode(json_encode($message)),true,Frame::OP_BINARY);
$conn->send($msg);
增加偵聽 onMessage 接收并分析消息:
->then(function(RatchetClientWebSocket $conn) {
$conn->on("message", function(RatchetRFC6455MessagingMessageInterface $msg) use ($conn) {
$jsMsg = json_decode(gzdecode($msg));
print_r($jsMsg);
if ($jsMsg->action === "CREATE_MESSAGE" and property_exists($jsMsg,"data")) {
echo "
Need reply server a receipt!
";
$RspMsg = generateReceipt($jsMsg->data->message_id);
$msg = new Frame(gzencode(json_encode($RspMsg)),true,Frame::OP_BINARY);
$conn->send($msg);
if ($jsMsg->data->category === "PLAIN_TEXT") {
$msgData = sendPlainText($jsMsg->data->conversation_id,
base64_decode($jsMsg->data->data));
$msg = new Frame(gzencode(json_encode($msgData)),true,Frame::OP_BINARY);
$conn->send($msg);
} //end of PLAIN_TEXT
} //end of CREATE_MESSAGE
});
$conn->on("close", function($code = null, $reason = null) {
echo "Connection closed ({$code} - {$reason})
";
});
Mixin Messenger支持的消息類型很多，具體可到下面鏈接查看: WebSocket消息類型.
每接收到一個消息，需要按消息編號(message_id)給服務器回復一個"已讀"的消息,避免服務器在機器人重新登入后，再次發送處理過的消息！
echo "
Need reply server a receipt!
";
$RspMsg = generateReceipt($jsMsg->data->message_id);
$msg = new Frame(gzencode(json_encode($RspMsg)),true,Frame::OP_BINARY);
$conn->send($msg);
function generateReceipt($msgID):Array {
$IncomingMsg = ["message_id" => $msgID, "status" => "READ"];
$RspMsg = ["id" => Uuid::uuid4()->toString(), "action" => "ACKNOWLEDGE_MESSAGE_RECEIPT",
"params" => $IncomingMsg];
return $RspMsg;
}
