课程简介
创建一个接受消息的机器人
通过本教程，你将学会如何用PHP创建一个机器人APP,让它能接受消息.
PHP 环境安装:
本教程的程序基于PHP 7开发，所以你需要先安装PHP7.2/PHP7.3与composer, 其中，composer是PHP的包管理系统!
on macOS
brew update brew install [email protected] 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;" //将PHP安装到/usr/local/opt/[email protected]/bin 目录，并取一个简单的各字：composer php composer-setup.php --install-dir=/usr/local/opt/[email protected]/bin --filename=composer php -r "unlink('composer-setup.php');"
如果之前你安装过php 7.1 或者更旧的php版本，执行brew unlink [email protected]删除这些链接，然后再执行brew link [email protected]将php 7.3链接到php.
wenewzha:mixin_labs-php-bot wenewzhang$ brew unlink [email protected] Unlinking /usr/local/Cellar/php/7.1.23... 24 symlinks removed wenewzha:mixin_labs-php-bot wenewzhang$ brew link [email protected] Warning: [email protected] 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/[email protected]/bin:$PATH"' >> ~/.bash_profile echo 'export PATH="/usr/local/opt/[email protected]/sbin:$PATH"' >> ~/.bash_profile
之后，根据你的系统实际情况，看看php -v能不能执行成功，如果不行，将默认的PATH设置并保存到.bash_profile.
echo 'export PATH="/usr/local/opt/[email protected]/bin:$PATH"' >> ~/.bash_profile echo 'export PATH="/usr/local/opt/[email protected]/sbin:$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;"
//将PHP安装到/usr/local/opt/[email protected]/bin 目录，并取一个简单的各字：composer
php composer-setup.php --install-dir=/usr/local/bin --filename=composer
php -r "unlink('composer-setup.php');"最新的Composer在这儿Composer
请确保PHP与composer安装在$PATH包含的目录之内，直接运行php -v 或 composer -V 就可以检查出来，如果提示如下，表示安装正确！
wenewzha:minecraft wenewzhang$ php -v
PHP 7.2.13 (cli) (built: Dec 7 2018 10:41:23) ( NTS )

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没有在$PATH下找到php,请重复以上的安装步骤！
wenewzha:mixin_network-nodejs-bot2 wenewzhang$ php -v -bash: php: command not found
创建你的项目
到你的工作文档中，创建一个目录，并取一个名字，比如:mixin_labs-php-bot
mkdir mixin_labs-php-bot cd mixin_labs-php-bot
转到新创建的项目目录下, 执行 composer init, 依提示完成 composer.json的创建,
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. Package name (<vendor>/<name>) [user/mixin_labs-php-bot]: Description []: PHP 7 bot for Mixin Messenger Author [, n to skip]: JimmyZhang <[email protected]> Minimum Stability []: Package Type (e.g. library, project, metapackage, composer-plugin) []: License []: Define your dependencies. Would you like to define your dependencies (require) interactively [yes]? no Would you like to define your dev dependencies (require-dev) interactively [yes]? no { "name": "user/mixin_labs-php-bot", "description": "PHP 7 bot for Mixin Messenger", "authors": [ { "name": "JimmyZhang", "email": "[email protected]" } ], "require": {} } Do you confirm generation [yes]? yes
本教程引用了 mixin-sdk-php 与 Ratchet pawl, mixin-sdk-php 是一个Mixin Network PHP SDK , Ratchet pawl 是一个WebSocket客户端.
打开composer.json, 在"require"增加两行引用:
"require": {
"exinone/mixin-sdk-php": "^1.1",
"ratchet/pawl": "^0.3.3",
},保存composer.json后，执行 composer install 来下载：
composer install
下载完成后，目录下会出现一个vendor的子目录。
root@iZj6cbmqen2lqp7l48nfgkZ:~/mixin_labs-php-bot# ls composer.json composer.lock vendor
如果你是git克隆的源代码，直接执行 composer install 来下载依赖包。
创建第一个机器人APP
按下面的提示，到mixin.one创建一个APPtutorial.
生成相应的参数
记下这些生成的参数
它们将用于config.php中.
在项目目录下，创建config.php,将生成的参数，替换成你的！

经典的Hello world
在项目目录下创建一个app.php文件，将下面的代码拷进去：
<?php
require __DIR__ . '/vendor/autoload.php';
use ExinOne\MixinSDK\Traits\MixinSDKTrait;
use ExinOne\MixinSDK\MixinSDK;
use Ramsey\Uuid\Uuid;
use Ratchet\RFC6455\Messaging\Frame;
$loop = \React\EventLoop\Factory::create();
$reactConnector = new \React\Socket\Connector($loop, [
'timeout' => 15
]);
$connector = new \Ratchet\Client\Connector($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(Ratchet\Client\WebSocket $conn) {
$conn->on('message', function(\Ratchet\RFC6455\Messaging\MessageInterface $msg) use ($conn) {
$jsMsg = json_decode(gzdecode($msg));
print_r($jsMsg);
if ($jsMsg->action === 'CREATE_MESSAGE' and property_exists($jsMsg,'data')) {
echo "\nNeed reply server a receipt!\n";
$RspMsg = generateReceipt($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})\n";
});
/* 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()}\n";
$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 $RspMsg;
}保存，并在终端里执行app.php
php app.php
如果一切正常，提示如下：
wenewzha:mixin_labs-php-bot wenewzhang$ 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
)在手机安装 Mixin Messenger,增加机器人为好友,(比如这个机器人是7000101639) 然后发送消息给它,效果如下!
源代码解释
WebSocket是建立在TCP基础之上的全双工通讯方式，我们需要建立一个loop循环来维持通迅。
$loop = \React\EventLoop\Factory::create();
$reactConnector = new \React\Socket\Connector($loop, [
'timeout' => 15
]);
$connector = new \Ratchet\Client\Connector($loop,$reactConnector);机器人APP通过Mixin Messenger服务器来接收用户发过来的消息，连接服务器，需要Token来验证用户的身份,
详细资料可参考如下链接:
Token认证, 接收服务器消息
mixin-sdk-php 实现了令牌Token的生成(getToken), 调用代码如下：
class callTraitClass {
use MixinSDKTrait;
public $config;
public function __construct()
{
$config = require(__DIR__.'/config.php');
$this->config = $config;
}
}
$callTrait = new callTraitClass();
$Token = $callTrait->getToken('GET', '/', '');连接到服务器，注意协议类型与Token:
$connector('wss://blaze.mixin.one', ['protocol' => 'Mixin-Blaze-1'],[
'Authorization' => 'Bearer '.$Token
])向服务器发送"LIST_PENDING_MESSAGES",这样服务器才会将收到的消息发送给机器人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);增加侦听 onMessage 接收并分析消息:
->then(function(Ratchet\Client\WebSocket $conn) {
$conn->on('message', function(\Ratchet\RFC6455\Messaging\MessageInterface $msg) use ($conn) {
$jsMsg = json_decode(gzdecode($msg));
print_r($jsMsg);
if ($jsMsg->action === 'CREATE_MESSAGE' and property_exists($jsMsg,'data')) {
echo "\nNeed reply server a receipt!\n";
$RspMsg = generateReceipt($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})\n";
});Mixin Messenger支持的消息类型很多，具体可到下面链接查看: WebSocket消息类型.
每接收到一个消息，需要按消息编号(message_id)给服务器回复一个"已读"的消息,避免服务器在机器人重新登入后，再次发送处理过的消息！
echo "\nNeed reply server a receipt!\n";
$RspMsg = generateReceipt($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;
}完成
现在你的机器人APP运行起来了，你打算如何改造你的机器人呢？
