我正在为我的小型培训项目制作联系表单。正在接收电子邮件，但似乎不正确。似乎我是从同一个电子邮件帐户发送给自己的
我正在使用nodemailer和Angular 。
这是sendEmail函数：

async function sendEmail(user,callback){
  const transporter = nodemailer.createTransport({
    host: "smtp.gmail.com",
    port:587,
    service: `gmail`,
    auth:{
      async function sendEmail(data,callback){

const transporter = nodemailer.createTransport({
    host: "smtp.gmail.com",
    port:587,
    service: `gmail`,
    auth:{
        user : `youremailwithoutprovider`,
        pass: `your 3rd party app Google password`
    }
})

 const mailOptions = {
  sender: data.email,
  to: `AUTH USER SHOULD BE HERE`,
  subject: data.subject,
  query: data.query,
  html: `
  <h2>From:</h2>
  <div>${data.email}</div>
  <h2>Subject:</h2>
  <div>${ data.subject}</div>
  <h2>Query:</h2>
  <div>${ data.query}</div>
  `
}

let info = await transporter.sendMail(mailOptions)

callback(info)
}

module.exports = {
  sendEmail
}

这是服务器中的控制器：

emailController.post(`/contact-us`, (req,res) => {
    console.log(`request came`)
    let user = req.body
   

    try {
        sendEmail(user,callback => {
      
        })
    } catch (error) {
        res.status(400).json({error:error.message})
    }

    res.end()
})

这是整个联系我们组件：

import { Component } from '@angular/core';
import { FormBuilder, Validators } from '@angular/forms';
import { Router } from '@angular/router';
import { ContactUsService } from './contact-us.service';

@Component({
  selector: 'app-contact-us',
  templateUrl: './contact-us.component.html',
  styleUrls: ['./contact-us.component.css']
})
export class ContactUsComponent {
  errors: any;
  constructor(private fb: FormBuilder,private emailService: ContactUsService, private router: Router ){}

  contactUs = this.fb.group({
    name: [``,[Validators.required, Validators.minLength(5)]],
    subject: [``, [Validators.required, Validators.maxLength(20)]],
    email: [``,[Validators.email, Validators.required]],
    query: [``, [Validators.required, Validators.minLength(15)]]
  })  

  sendEmail(){
  let user = {
    name : this.contactUs.get(`name`)?.value,
    email : this.contactUs.get(`email`)?.value,
    subject : this.contactUs.get(`subject`)?.value,
    query:  this.contactUs.get(`query`)?.value,
  } 
  this.emailService.sendEmail(user).subscribe({
    

      next: () => this.router.navigate([`/`]),
      error:(err)=>   {
        this.errors = err.error?.error
      }

    })
  
    this.contactUs.reset()
  
  }
}

这是Angular 的服务：

import { HttpClient } from '@angular/common/http';
import { Injectable } from '@angular/core';
import { Router } from '@angular/router';
import { IQuery } from '../interfaces/query';

const API_CONTACT_US_EMAIL = `http://localhost:3000/contact-us`

@Injectable({
  providedIn: 'root'
})
export class ContactUsService {

  query : null | IQuery | undefined
  constructor(private http: HttpClient, private router: Router) { }

  sendEmail(data: {}){
    return this.http.post<IQuery>(`${API_CONTACT_US_EMAIL}`, data)
  }
}

这一切都是工作，表格正在填写正确，电子邮件收到，只是发件人是错误的gmail -这是相同的电子邮件地址。
您可以看到，我在服务器上使用过几次console.log，从它们那里似乎提取了适当的数据，但我认为在nodemailer中发生了一些事情。

request came
 Email sent

我错过了什么？
谢谢
