Lambda function 无法发送 email with HTML 表单数据

Question

I am new to AWS Lambda and I am trying to send an email with details submitted in an HTML form using AWS SES.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。 I tested out the lambda function with hard coded values and the emails worked fine.我用硬编码值测试了 lambda function，电子邮件工作正常。 Below is the initial code: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',
    )

I am now trying to replace the form data (post method) in the email body.我现在正在尝试替换 email 正文中的表单数据（post 方法）。 This is my new code: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',
        )

The above code does not throw any error in the Cloud Watch logs but it does not deliver the email also.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。 What am I missing here?我在这里错过了什么？

Following is the cloud watch log:以下是云监视日志：

I can't diagnose in it's entirety, but I've re-written the snippet in a way the allows me to debug my Lambda's with a little more feedback.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。 Keep in a mind, a lambda succeeding doesn't necessarily mean the code was executed as you expect it to, which is where feedback from the invocation helps validate expected behavior.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。

If the final response provides a MessageId and a code of 200, I would explore the email client settings next.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"))
    }
