所以，在找到一些github代码示例后，我已经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，你必须使用botman框架中名为startConversation()的函数来调用它，你需要引用扩展基类Conversation中的bot。因此，您需要一个入口点，然后是您想要链接到的对话，如下所示：* 注意，您将需要每个会话的默认入口点run（）。

//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;
                    }
                }
            });
        }
    }
