Node.js 使用sendgrid未处理PromisejectionWarning

我被困了很长一段时间，现在我得到了这个错误，上面写着UnhandledPromisejectionWarning，这不是我在表单控制器中捕捉到的错误

npm版本

@sendgrid/mail:“^6.4.0”

当我尝试使用邮递员正文发送电子邮件时：

（节点：1504）未处理的PromisejectionWarning:未处理的承诺拒绝。此错误源于在没有catch块的异步函数中抛出，或者拒绝未使用.catch（）处理的承诺。要在未处理的承诺拒绝时终止节点进程，请使用CLI标志

--unhandled rejections=strict

（请参阅）。（拒绝id:2）

这个对象是我从捕捉错误中得到的

电子邮件表单控制器

const sgMail = require('@sendgrid/mail'); // SENDGRID_API_KEY
sgMail.setApiKey(process.env.SENDGRID_API_KEY);

    exports.contactForm = (req, res) => {
        const { email, name, message } = req.body;
        // console.log(req.body);
    
        const emailData = {
            to: process.env.EMAIL_TO,
            from: email,
            subject: `Contact form - ${process.env.APP_NAME}`,
            text: `Email received from contact from \n Sender name: ${name} \n Sender email: ${email} \n Sender message: ${message}`,
            html: `
                <h4>Email received from contact form:</h4>
                <p>Sender name: ${name}</p>
                <p>Sender email: ${email}</p>
                <p>Sender message: ${message}</p>
                <hr />
                <p>This email may contain sensetive information</p>
            `
        };
    
        sgMail.send(emailData).then(sent => {
            return res.json({
                success: true
            }).catch(error=>{
                console.log('error',error)
            })
        
        });
    };
    
    exports.contactAssignmentAuthorForm = (req, res) => {
        const { authorEmail, email, name, message } = req.body;
        // console.log(req.body);
    
        let maillist = [authorEmail, process.env.EMAIL_TO];
    
        const emailData = {
            to: maillist,
            from: email,
            subject: `Someone messaged you from ${process.env.APP_NAME}`,
            text: `Email received from contact from \n Sender name: ${name} \n Sender email: ${email} \n Sender message: ${message}`,
            html: `
                <h4>Message received from:</h4>
                <p>name: ${name}</p>
                <p>Email: ${email}</p>
                <p>Message: ${message}</p>
                <hr />
                <p>This email may contain sensetive information</p>
         
            `
        };
    
        sgMail.send(emailData).then(sent => {
            return res.json({
                success: true
            }).catch((error) => {
                console.log('error', error);
            });
        });
    };

表单验证程序

const { check } = require('express-validator');

exports.contactFormValidator = [
    check('name')
        .not()
        .isEmpty()
        .withMessage('Name is required'),
    check('email')
        .isEmail()
        .withMessage('Must be valid email address'),
    check('message')
        .not()
        .isEmpty()
        .isLength({ min: 15 })
        .withMessage('Message must be at least 20 characters long')
];

您在错误的行中使用catch，

res.json

不需要

catch

块。将catch块连接到

sendgrid。然后使用如下方法

    sgMail.send(emailData).then(sent => {
        return res.json({
            success: true
        })
    }).catch(error=>{
       console.log('error',error)
    })

另外，不要在公共场合发布这样的API密钥，它们不需要理解您的代码。
按照本指南sendgrid.com/docs/ui/sending email/sender verification解决了问题。您需要验证您的发件人才能完成此操作。
仍然无法解决同一问题，sendgrid中是否有任何配置我应该关心设置->Api键->我创建了一个，并复制了它，就是说，有两个地方你必须做相同的事情（catch block），你更新了这两个地方吗（即在
contactAssignmentAuthorForm
和
contactForm
功能中？我只是在经过大量研究后更新了代码，我认为他们更新了身份验证的方式，它需要一些配置[链接]我查看了，似乎首先您必须创建发件人的身份和API密钥，并将特定IP地址的列表添加到列表中才能成功发送电子邮件。您可以使用
error.response.body
记录错误响应正文，以详细查看错误。
    sgMail.send(emailData).then(sent => {
        return res.json({
            success: true
        })
    }).catch(error=>{
       console.log('error',error)
    })
