【问题描述】：

我使用 SendGrid，我知道我的 SendGrid-API 密钥正在通过从终端检查来工作。 我在 SendGrid 发件人身份中验证了我的电子邮件。

curl -i --request POST \
--url https://api.sendgrid.com/v3/mail/send \
--header 'Authorization: Bearer MY-API-KYE_HERE' \
--header 'Content-Type: application/json' \
--data '"personalizations": ["to": ["email": "[e-mail]"]],"from": "email": "[e-mail]","subject": "SendGrid Test!","content": ["type": "text/plain", "value": "Howdy!"]'

我收到一封电子邮件。

它也适用于本地主机。

但是当我使用以下代码部署到 Vercel 时，它不会发送任何电子邮件。

import sgMail from '@sendgrid/mail'
import dotenv from 'dotenv'
dotenv.config()

const host = process.env['HOST_URL']
const email_from = process.env['EMAIL_FROM']
const SENDGRID_API_KEY = process.env['SENDGRID_API']

export const sendGridConfirmationEmail = async (name, email, confirmationCode) => 
  await sgMail.setApiKey(SENDGRID_API_KEY)
  const msg = 
    to: email,
    from: `$email_from`,
    subject: "Please confirm your account",
    text: `Email Confirmation: Hello $name.
    Please confirm your email by clicking on the following link.
    Click here, $host/auth/confirm/$confirmationCode`,
    html:`<h1>Email Confirmation</h1>
    <h2>Hello $name</h2>
    <p>Please confirm your email by clicking on the following link.</p>
    <a href=$host/auth/confirm/$confirmationCode> Click here</a>
    </div>`,
  
  await sgMail
    .send(msg)
    .then(() => 
      console.log('Email sent')
    )
    .catch((error) => 
      console.error(error)
    )

我也尝试了以下方法，但也没有用。

export const sendGridConfirmationEmail = async (name, email, confirmationCode) => 
   await fetch(SENDGRID_API, 
     method: 'POST',
     headers: 
       'Content-Type': 'application/json',
       Authorization: `Bearer $SENDGRID_API_KEY`
     ,
     body: JSON.stringify(
       personalizations: [
         
           to: [
             
               email
             
           ],
           subject: 'Demo success :)'
         
       ],
       from: 
         email: email_from,
         name: 'Test SendGrid'
       ,
       content: [
         
           type: 'text/html',
           value: `Congratulations <b>$name</b>, you just sent an email with sendGrid. $confirmationCode`
         
       ]
     )
 );

如何使用 SendGrid 从 Vercel 发送电子邮件？

【问题讨论】：

一个函数的 Vercel 超时为 5 秒，可能是它在完成执行之前被丢弃，因此无法发送电子邮件

【参考方案1】：

我解决了这个问题。

当我调用sendGridConfirmationEmail时，我需要使用await。

export const post = async ( body ) => 
...

 if (mail_method === "sendgrid") 
    await sendGridConfirmationEmail(
      body.name,
      body.email,
      token
    );
      console.log('SendGrid registration is emailed.')
  
...
