我尝试创建一个lambda函数来发送电子邮件。问题是我无法在Lambda上获取电子邮件模板路径。我收到的错误是:
“ errorMessage”:“ ENOENT:没有这样的文件或目录,请打开'/var/task/email_template.ejs'”
service.js:
export const generateEmail = async (subject, text, email) => {
try {
const pathName = process.env.LAMBDA_TASK_ROOT
? path.resolve(process.env.LAMBDA_TASK_ROOT, 'email_template.ejs')
: path.resolve(__dirname, 'email_template.ejs')
const data = await ejs.renderFile(pathName, {
name: 'John Doe'
})
return {
from: '"Service" <no-reply.service@ses.com>',
to: email,
subject: subject,
text: text,
html: data
}
} catch (err) {
throw err
}
}
sendMail.js
exports.handler = async (event, context, callback) => {
if (event.httpMethod === 'POST' && event.body) {
const req = JSON.parse(event.body)
const { name, email } = req
if (!email.match(/^[^@]+@[^@]+$/)) {
console.log('Not sending: invalid email address', body.email)
return callback(null, {
statusCode: 400,
body: JSON.stringify({
error_code: 'invalid_email',
message: 'Cannot send. Your email is invalid'
})
})
}
const config = {
accessKeyId: process.env.ACCESS_KEY,
secretAccessKey: process.env.SECRET_KEY
}
const transporter = nodemailer.createTransport(ses(config))
const mailOptions = await generateEmail('Hello ✔', 'Hello world', email)
try {
await transporter.sendMail(mailOptions)
return callback(null, {
statusCode: 204
})
} catch (err) {
return callback(null, {
statusCode: 400,
body: JSON.stringify({
error_code: 'general_error',
message: 'Please try again later',
full_error: err
})
})
}
}
return callback(null, {
statusCode: 400,
body: JSON.stringify({
error_code: 'missing_parameters',
message: 'Please provide your name and email'
})
})
}
generateEmail函数在本地完美运行,但不适用于lambda函数。
任何帮助将不胜感激,谢谢!

我终于找到了答案。 原因是因为在webpack构建时,它会忽略我的email_template.ejs文件。
因此,我将此行添加到webpack.config.js中,以使其存在于zip输出中,并且效果很好。
uri_duration = 90
s3Client = boto3.client('s3')
url = s3Client.generate_presigned_url('get_object', Params =
{'Bucket': bucket,
'Key': filekey'}, ExpiresIn = uri_duration)
