javascript - Bot Framework [Node.js] Bot 不匹配单词

Question

我在将 bot.customAction 用于简单的 QnA 对象时遇到问题，预期结果是发送“我一如既往地很棒，但感谢您的询问!”如果用户发送“Fine and you?”、“Well and you?”、“Good and you?”，我尝试了以下 2 个选项

第一个选项:

bot.customAction({
    matches: /^Fine and you$|^Good and you$|^Well and you$/i,
    onSelectAction: (session, args, next) => {
        session.send("I'm wonderful as always, but thanks for asking!");
    }
});

第二个选项:

bot.customAction({
    matches: "Fine and you?"|"Good and you?"|"Well and you?",
    onSelectAction: (session, args, next) => {
        session.send("I'm wonderful as always, but thanks for asking!");
    }
});

在第一个选项中，匹配项只识别没有问号“?”的准确单词

[BotFramework Emulator] Word recognized without the question mark "?"

在第二个选项中没有任何反应，只是开始 waterfall 对话

[BotFramework Emulator] Second option is ignored by bot and start the waterfall conversation

感谢您的宝贵时间!

Answer 1

简答

bot.customAction({
    matches: /^Fine and you|^Good and you|^Well and you/i,
    onSelectAction: (session, args, next) => {
        session.send("I'm wonderful as always, but thanks for asking!");
    }
});

第一个选项

在正则表达式中，^ 代表字符串的开头，$ 代表字符串的结尾。因此，当您的正则表达式是 /^Fine and you$/ 时，您匹配的是 Fine and you，开头或结尾没有额外的内容。

要解决此问题，您需要使正则表达式更加灵活。

/^Fine and you\??$/ 'Fine and you' with optional问号

/^Fine and you/ 任何以 'Fine and you' 开头，后面有任何其他内容的字符串(Fine and you foobar blah blah 也会匹配)

第二个选项

bot.customAction({
    matches: "Fine and you?"|"Good and you?"|"Well and you?",
    onSelectAction: (session, args, next) => {
        session.send("I'm wonderful as always, but thanks for asking!");
    }
});

在此示例中，您使用的是 bitwise OR运算符 (|)

表达式 "Fine and you?"|"Good and you?"|"Well and you?" 将解析为 0，因此这段代码实际上正在运行

bot.customAction({
    matches: 0,
    onSelectAction: (session, args, next) => {
        session.send("I'm wonderful as always, but thanks for asking!");
    }
});

您应该改用第一个示例中提供的正则表达式的修改版本。
