node.js - 从 Node.js 中的 sendGrid 发送电子邮件时出现“UnhandledPromiseRejectionWarning：错误：禁止”

问题描述

我正在按照他们网站上的说明将 sendgrid 与以下代码集成到我的 node.js 项目中

const sgMail = require('@sendgrid/mail')

const sendGridAPIKey = "API key"

sgMail.setApiKey(sendGridAPIKey)

const msg = {
 to: 'agrawalanuj751997@gmail.com',
 from: 'agrawalanuj751997@gmail.com',
 subject:'My first mail from node',
 text:"I'm sending myself an email"
}

sgMail.send(msg)

我的日志中出现以下错误。我尝试了来自多个帐户的多个 API 密钥，但仍然遇到相同的错误。

解决方案

我也面临着类似的问题。我认为他们需要更新文档。send 方法返回一个您尚未处理的承诺，这就是您收到错误的原因。

改变

sgMail.send(msg)

至

sgMail.send(msg).then(() => {
    console.log('Message sent')
}).catch((error) => {
    console.log(error.response.body)
    // console.log(error.response.body.errors[0].message)
})

现在，未处理的 Promise 拒绝错误将消失，并且您将收到错误为什么 Promise 被拒绝。

就像是

发件人地址与已验证的发件人身份不匹配。在解决此错误之前无法发送邮件。访问https://sendgrid.com/docs/for-developers/sending-email/sender-identity/查看发件人身份要求

这是不言自明的。转到指定的链接，它将引导您验证自我身份。完成后，它应该可以正常工作。
