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 php@7.2
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('sha384', 'composer-setup.php') === '93b54496392c062774670ac18b134c3b3a95e5a5e5c8f1a9f115f203b75bf9a129d5daa8ba6a13e2cc8a1da0806388a8') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
//将 PHP 安装到 /usr/local/opt/php@7.2/bin 目录，并取一个简单的各字：composer
php composer-setup.php --install-dir=/usr/local/opt/php@7.2/bin --filename=composer
php -r "unlink('composer-setup.php');"

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') === '93b54496392c062774670ac18b134c3b3a95e5a5e5c8f1a9f115f203b75bf9a129d5daa8ba6a13e2cc8a1da0806388a8') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
//将 PHP 安装到 /usr/local/opt/php@7.2/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');"

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 )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies
    with Zend OPcache v7.2.13, Copyright (c) 1999-2018, by 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 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]:

{
   "name": "user/mixin_labs-php-bot",
   "description": "PHP 7 bot for Mixin Messenger",
   "authors": [
       {
           "name": "JimmyZhang",
           "email": "zhangjingping@mixin.one"
       }
   ],
   "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 APP

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！

config.php

return [

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

好担心这玩意被注入一下


那真是损失几个亿
