Lambda function 无法发送 email with HTML 表单数据

Question

我是 AWS Lambda 的新手，我正在尝试发送一个 email，其中包含使用 AWS SES 在 HTML 表单中提交的详细信息。 我用硬编码值测试了 lambda function，电子邮件工作正常。 下面是初始代码：

# Lambda Function for Contact Forms using AWS SES

import boto3
import datetime

def lambda_handler(event, context):
    client = boto3.client('ses')

    response = client.send_email(
        Destination={
            'BccAddresses': [
            ],
            'CcAddresses': [
                'abc@gmail.com',
            ],
            'ToAddresses': [
                'abc@example.com',
            ],
        },
        Message={
            'Body': {
                'Html': {
                    'Charset': 'UTF-8',
                    'Data': 'This message body contains HTML formatting. It can, for example, contain links like this one: <a class="ulink" href="http://docs.aws.amazon.com/ses/latest/DeveloperGuide" target="_blank">Amazon SES Developer Guide</a>.',
                },
                'Text': {
                    'Charset': 'UTF-8',
                    'Data': 'This is the message body in text format.',
                },
            },
            'Subject': {
                'Charset': 'UTF-8',
                'Data': 'Test email sent at '+datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S'),
            },
        },
        ReplyToAddresses=['xyz@gmail.com',
        ],
        Source='abc@example.com',
    )

我现在正在尝试替换 email 正文中的表单数据（post 方法）。 这是我的新代码：

# Lambda Function for Contact Forms using AWS SES

import boto3
import datetime

def lambda_handler(event, context):
    client = boto3.client('ses')
    error = None

    # Read form values.
    full_name = event.get('fullname')
    email_addr = event.get('emailid')
    subject = event.get('subject')
    msg_body = event.get('msgbody')
    
    # Check form data.
    if not full_name:
        error = 'Full name is required.'
    elif not email_addr:
        error = 'Email address is required.'
    elif not subject:
        error = 'Subject is required.'
    elif not msg_body:
        error = 'Message body is required.'

    if error is None:
        response = client.send_email(
            Destination={
                'BccAddresses': [
                ],
                'CcAddresses': [
                    'abc@gmail.com',
                ],
                'ToAddresses': [
                    'abc@example.com',
                ],
            },
            Message={
                'Body': {
                    'Html': {
                        'Charset': 'UTF-8',
                        'Data': msg_body,
                    },
                    'Text': {
                        'Charset': 'UTF-8',
                        'Data': msg_body,
                    },
                },
                'Subject': {
                    'Charset': 'UTF-8',
                    'Data': subject+' | example.com | '+datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S'),
                },
            },
            ReplyToAddresses=[email_addr,
            ],
            Source='abc@example.com',
        )

上面的代码不会在 Cloud Watch 日志中抛出任何错误，但它也不会传送 email。 我在这里错过了什么？

我无法对其进行完整诊断，但我以某种方式重写了该代码段，使我可以通过更多反馈来调试我的 Lambda。 请记住，lambda 成功并不一定意味着代码已按预期执行，这是来自调用的反馈有助于验证预期行为的地方。

如果最终响应提供 MessageId 和代码 200，接下来我将探索 email 客户端设置。

import boto3
import datetime, json

def lambda_handler(event, context):
    client = boto3.client('ses')

    full_name = event.get('fullname')
    email_addr = event.get('emailid')
    subject = event.get('subject')
    msg_body = event.get('msgbody')

    if None in [full_name, email_addr, subject, msg_body]:
        return {
            "statusCode": 500,
            "body": json.dumps("Error in email variable definitions.")
        }
    

    try:
        response = client.send_email(...)
    except Exception as e:
        return {
            "statusCode": 500,
            "body": json.dumps("Failed to send email: {}".format(e))
        }

    return {
        "statusCode": 200,
        "body": "Email ID: {} sent from Lambda.".format(response.get("MessageId"))
    }
