## 交互响应控制器 如果在创建插件的时候勾选了*是否需要响应规则*,则插件创建成功后会自动生成一个RespondController,在RespondController.class.php中会有一个自动生成的wechat方法用于接收微信端消息并进行响应。 例如*聊天机器人*插件,在创建的时候勾选了*是否需要响应规则*,然后在后台响应规则处设置了一个触发关键词*聊天*,那么当用户在微信端发送消息“聊天”的时候,用户的此条微信消息会被分发到聊天机器人插件的RespondController.class.php中的wechat方法进行响应。我们可以这样来进行响应: ~~~ <?php namespace Addons\IdouChat\Controller; use Mp\Controller\ApiController; /** * 聊天机器人响应控制器 * @author 艾逗笔 */ class RespondController extends ApiController { /** * 微信交互 * @param $message array 微信消息数组 * @author 艾逗笔<765532665@qq.com> */ public function wechat($message = array()) { $settings = get_addon_settings('IdouChat'); $settings['enter_tip'] || $settings['enter_tip'] = '你想聊点什么呢'; $settings['keep_time'] || $settings['keep_time'] = 300; $settings['exit_keyword'] || $settings['exit_keyword'] = '退出'; $settings['exit_tip'] || $settings['exit_tip'] = '下次无聊的时候可以再找我聊天哦'; if (!$settings['api_url'] || !$settings['api_key']) { reply_text('机器人聊天接口未填写,暂时不能使用此功能'); exit(); } if ($this->message['MsgType'] == 'voice') { if ($settings['can_voice'] == '1') { $content = $this->message['Recognition']; // 语音识别,直接开启机器人聊天模式 $reply = $this->turingAPI($content); if (is_array($reply)) { return reply_news($reply); } else { return reply_text($reply); } } } else { $content = $this->message['Content']; // 通过消息上下文机制与机器人展开聊天 if (!$this->in_context) { $reply = $settings['enter_tip']; $this->begin_context($settings['keep_time']); // 开启上下文模式 } else { if ($content == $settings['exit_keyword']) { $reply = $settings['exit_tip']; $this->end_context(); } else { $reply = $this->turingAPI($content); $this->keep_context($settings['keep_time']); // 保持消息上下文 } } if (is_array($reply)) { return reply_news($reply); } else { return reply_text($reply); } } } // 图灵机器人 private function turingAPI($keyword) { $settings = get_addon_settings('IdouChat'); $settings['api_url'] || $settings['api_url'] = ''; $settings['api_key'] || $settings['api_key'] = ''; $api_url = $settings['api_url'] . "?key=" . $settings['api_key'] . "&info=" . $keyword; $result = file_get_contents ( $api_url ); $result = json_decode ( $result, true ); if ($_GET ['format'] == 'test') { dump ( '图灵机器人结果:' ); dump ( $result ); } if ($result ['code'] > 40000 && $result['code'] < 40008) { if ($result ['code'] < 40008 && ! empty ( $result ['text'] )) { return '图灵机器人请你注意:' . $result ['text']; } else { return false; } } switch ($result ['code']) { case '100000' : return $result['text']; break; case '200000' : $text = $result ['text'] . ',<a href="' . $result ['url'] . '">点击进入</a>'; return $text; break; case '301000' : foreach ( $result ['list'] as $info ) { $articles [] = array ( 'Title' => $info ['name'], 'Description' => $info ['author'], 'PicUrl' => $info ['icon'], 'Url' => $info ['detailurl'] ); } return $articles; break; case '302000' : foreach ( $result ['list'] as $info ) { $articles [] = array ( 'Title' => $info ['article'], 'Description' => $info ['source'], 'PicUrl' => $info ['icon'], 'Url' => $info ['detailurl'] ); } return $articles; break; case '304000' : foreach ( $result ['list'] as $info ) { $articles [] = array ( 'Title' => $info ['name'], 'Description' => $info ['count'], 'PicUrl' => $info ['icon'], 'Url' => $info ['detailurl'] ); } return $articles; break; case '305000' : foreach ( $result ['list'] as $info ) { $articles [] = array ( 'Title' => $info ['start'] . '--' . $info ['terminal'], 'Description' => $info ['starttime'] . '--' . $info ['endtime'], 'PicUrl' => $info ['icon'], 'Url' => $info ['detailurl'] ); } return $articles; break; case '306000' : foreach ( $result ['list'] as $info ) { $articles [] = array ( 'Title' => $info ['flight'] . '--' . $info ['route'], 'Description' => $info ['starttime'] . '--' . $info ['endtime'], 'PicUrl' => $info ['icon'], 'Url' => $info ['detailurl'] ); } return $articles; break; case '307000' : foreach ( $result ['list'] as $info ) { $articles [] = array ( 'Title' => $info ['name'], 'Description' => $info ['info'], 'PicUrl' => $info ['icon'], 'Url' => $info ['detailurl'] ); } return $articles; break; case '308000' : foreach ( $result ['list'] as $info ) { $articles [] = array ( 'Title' => $info ['name'], 'Description' => $info ['info'], 'PicUrl' => $info ['icon'], 'Url' => $info ['detailurl'] ); } return $articles; break; case '309000' : foreach ( $result ['list'] as $info ) { $articles [] = array ( 'Title' => $info ['name'], 'Description' => '价格 : ' . $info ['price'] . ' 满意度 : ' . $info ['satisfaction'], 'PicUrl' => $info ['icon'], 'Url' => $info ['detailurl'] ); } return $articles; break; case '310000' : foreach ( $result ['list'] as $info ) { $articles [] = array ( 'Title' => $info ['number'], 'Description' => $info ['info'], 'PicUrl' => $info ['icon'], 'Url' => $info ['detailurl'] ); } return $articles; break; case '311000' : foreach ( $result ['list'] as $info ) { $articles [] = array ( 'Title' => $info ['name'], 'Description' => '价格 : ' . $info ['price'], 'PicUrl' => $info ['icon'], 'Url' => $info ['detailurl'] ); } return $articles; break; case '312000' : foreach ( $result ['list'] as $info ) { $articles [] = array ( 'Title' => $info ['name'], 'Description' => '价格 : ' . $info ['price'], 'PicUrl' => $info ['icon'], 'Url' => $info ['detailurl'] ); } return $articles; break; default : if (empty ( $result ['text'] )) { return false; } else { return $result ['text']; } } return true; } } ~~~ 其中,$this->message或者$message数组里面包含了分发到wechat方法的用户消息,包含ToUserName、FromUserName、Content等信息。通过get_addon_settings可以获取插件的配置参数,通过$this->begin_context可以设置消息上下文、通过reply_text可以回复文本消息等。 总而言之。RespondController是用于接收用户通过微信发送来的消息并进行响应的控制器,如果插件的功能需要在微信对话框通过消息的收发来进行交互的话,那么在创建插件的时候就需要选择响应规则,并在微信响应控制器中设计对应的业务逻辑来对用户消息进行响应。
