php - Laravel Botman 问题 - 嵌套在 botman 类中后无法调用同一类的函数

Question

我正在尝试在 laravel 中使用 Botman 中的本机按钮和问题功能，但是我很难理解如何在不使用静态函数的情况下链接函数。我让它在一切都是静态功能的地方工作，但是我想使用收集到的所有信息来发送电子邮件。

    // initialization function
     public function handle()
     {
         $botman->hears("{message}", function($botman, $message) {
                $this->selectHelpQuery($botman);
         });
     }

     // ask question function 
     public function selectHelpQuery($botman)
     {
         $question = Question::create("How can i help you, would you like to know about the following:")
                ->fallback("Unable to help at this time, please try again later")
                ->callbackId("choose_query")
                ->addButtons([
                    Button::create("button1")->value("val1"),
                    Button::create("button2")->value("val2"),
                ]);
          $botman->ask($question, function (Answer $answer, $botman) {
              // Detect if button was clicked:
              if ($answer->isInteractiveMessageReply()) {
                  if($answer->getValue() == "val1") 
                  {
                      $this->contactFollowUp($botman); //** not working
                  } else {
                      $this->contactNoFollowUp($botman); //** not working
                  }
              }
          });
      }

// other functions.....

但是，没有将contactFollowUp()函数声明为静态并使用类名访问它BotManController::contactFollowUp($botman)但是如果我这样做，我在访问和设置用于其他函数的数据时会遇到问题。具体来说，我得到一个 Method contactFollowUp 不存在错误。

因此，在找到一些 github 代码示例后，我设法解决了这个问题。这与 botman 框架的结构方式有关。要实现链接对话，您必须使用 botman 框架中的一个函数来调用startConversation()这个函数，您需要引用bot该函数，该函数来自扩展基类 Conversation。所以你需要一个入口点，然后是你想要链接的对话，如下所示： *注意，每个对话都需要 run() 的默认入口点。

//BotManController.php
<?php

    namespace App\Http\Controllers\Chatbot;

    use App\Http\Controllers\Controller;
    use BotMan\BotMan\BotMan;
    use Illuminate\Http\Request;
    use BotMan\BotMan\Messages\Incoming\Answer;
    use BotMan\BotMan\Messages\Outgoing\Actions\Button;
    use BotMan\BotMan\Messages\Outgoing\Question;

    class BotManController extends Controller
    {
        /**
         * start the conversation on intitlization
         */
        public function handle()
        {
            $botman = app("botman");
            $botman->hears("{message}", function($botman, $message) {
                $botman->startConversation(new BotManStart);
            });
            $botman->listen();
        }
    }

然后

// BotManStart.php    
<?php

    namespace App\Http\Controllers\Chatbot;

    use BotMan\BotMan\BotMan;
    use Illuminate\Http\Request;
    use BotMan\BotMan\Messages\Incoming\Answer;
    use BotMan\BotMan\Messages\Outgoing\Actions\Button;
    use BotMan\BotMan\Messages\Outgoing\Question;
    use BotMan\BotMan\Messages\Conversations\Conversation;

    class BotManStart extends Conversation
    {
        public function run()
        {
            $this->selectHelpQuery();
        }

        public function selectHelpQuery()
        {
            $question = Question::create("How can i help you, would you like to know about the following: ")
                ->fallback("Unable to help at this time, please try again later")
                ->callbackId("choose_query")
                ->addButtons([
                    Button::create("Button 1")->value("button1"),
                    Button::create("Button 2")->value("button2"),
                ]);
            $this->ask($question, function (Answer $answer) {
                if ($answer->isInteractiveMessageReply()) {
                    switch ($answer->getValue()) {
                        case "button1":
                            $this->bot->startConversation(new BotManConversation1());
                            break;
                        case "button2":
                            $this->bot->startConversation(new BotManConversation2());
                            break;
                    }
                }
            });
        }
    }
