我正在尝试向某人发送电子邮件。我在控制台中打印成功消息,并且我的代码可以正常工作并成功发送电子邮件,但是当我在代理中将其作为消息打印时,它在响应之前显示为不可用。这是我的代码:

function sendEmail(agent){
//get email and name and message and subject

  console.log("Email befor getting: " +fetchedEmail);
  getEmail(agent.parameters.name).then(function(){
    console.log("the email is fetched: "+fetchedEmail);

    const nodemailer = require('nodemailer');
    const transporter = nodemailer.createTransport({
      service: 'gmail',
      auth: {
        user: '*********@gmail.com',
        pass: '*******************'
      }
    });
    var mailOptions = {
      from: '*******@gmail.com',
      to: fetchedEmail, //receiver email 
      subject: agent.parameters.subject,
      text: agent.parameters.message
    };


    return createMessage(mailOptions,transporter).then(()=>{
      console.log("email sent successfully");//this message printed on console
      agent.add(`email sent successfully`);// this not printed in agent

    }).catch(()=>{
      agent.add(`fail`);
    });




  });
}// end of send email

function createMessage(mailOptions,transporter){
return new Promise((resolve,reject)=>{
  // i promise to send email
  transporter.sendMail(mailOptions, function (error, info) {
        if (error) {
          console.log("there is error");
          reject(error);
        } else {
          console.log("success");// printed on console
          resolve('Email sent: ' + info.response);
        }
      });



});


}//end of create message

问题是您正在使用Promises执行异步功能(对getEmail()createMessage()的调用),但是您没有从sendEmail()本身返回Promise。

如果您正在执行异步功能,则Dialogflow库要求返回一个Promise,以便Intent Handler调度程序知道您正在执行异步功能。

对于您来说,最简单的方法是从getEmail().then()链中返回Promise。因此,更改这样的行应该有效:

return getEmail(agent.parameters.name).then(function(){
