AWS Lambda无法通过AWS SES发送电子邮件

我已验证以下内容

  1. AWS SES不在沙盒中。我可以通过控制台将电子邮件发送到未经验证的电子邮件ID。
  2. 我的Lambda函数具有一个角色,可以完全访问SES和Lambda(因为其最初的基本测试提供了完整的权限)

以下是AWS文档中的基本代码,仅对我的电子邮件ID进行了硬编码。但是我无法收到任何电子邮件。 lambda代码成功运行,但是我没有收到电子邮件。

import json
import os
import boto3
from botocore.exceptions import ClientError
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.application import MIMEApplication

print('Loading function')


def lambda_handler(event, context):
    print("Received event: " + json.dumps(event, indent=2))
    #print("value1 = " + event['key1'])
    #print("value2 = " + event['key2'])
    #print("value3 = " + event['key3'])
    #return event['key1']  # Echo back the first key value
    #raise Exception('Something went wrong')
    SENDER = "[redacted email]"
    RECIPIENT = event['email']
    CONFIGURATION_SET = "ConfigSet"
    AWS_REGION = "us-east-2"
    SUBJECT = "Contact Us Form Details"
    # The email body for recipients with non-HTML email clients.
BODY_TEXT = "Hello,\r\nPlease see the attached file for a list of customers to contact."

# The HTML body of the email.
BODY_HTML = """\
<html>
<head></head>
<body>
<h1>Hello!</h1>
<p>Please see the attached file for a list of customers to contact.</p>
</body>
</html>
"""

# The character encoding for the email.
CHARSET = "utf-8"

# Create a new SES resource and specify a region.
client = boto3.client('ses',region_name='us-east-2')

# Create a multipart/mixed parent container.
msg = MIMEMultipart('mixed')
# Add subject, from and to lines.
msg['Subject'] = "Contact Us Form Details" 
msg['From'] ="[redacted email]" 
msg['To'] = "[redacted email]"

# Create a multipart/alternative child container.
msg_body = MIMEMultipart('alternative')

# Encode the text and HTML content and set the character encoding. This step is
# necessary if you're sending a message with characters outside the ASCII range.
textpart = MIMEText(BODY_TEXT.encode(CHARSET), 'plain', CHARSET)
htmlpart = MIMEText(BODY_HTML.encode(CHARSET), 'html', CHARSET)

# Add the text and HTML parts to the child container.
msg_body.attach(textpart)
msg_body.attach(htmlpart)

# Define the attachment part and encode it using MIMEApplication.
#att = MIMEApplication(open(ATTACHMENT, 'rb').read())

# Add a header to tell the email client to treat this part as an attachment,
# and to give the attachment a name.
#att.add_header('Content-Disposition','attachment',filename=os.path.basename(ATTACHMENT))

# Attach the multipart/alternative child container to the multipart/mixed
# parent container.
msg.attach(msg_body)

# Add the attachment to the parent container.
#msg.attach(att)
print(msg)
try:
    #Provide the contents of the email.
    response = client.send_raw_email(
        Source="[redacted email]",
        Destinations=[
            "[redacted email]"
        ],
        RawMessage={
            'Data':msg.as_string(),
        },
        #ConfigurationSetName=CONFIGURATION_SET
    )
# Display an error if something goes wrong. 
except ClientError as e:
    print(e.response['Error']['Message'])
else:
    print("Email sent! Message ID:"),
    print(response['MessageId'])

如果您的代码确实是您向我们显示的内容,那么它之所以没有发送电子邮件,是因为您的一半代码没有被执行。

def lambda_handler(event, context):
    print("Received event: " + json.dumps(event, indent=2))
    #print("value1 = " + event['key1'])
    #print("value2 = " + event['key2'])
    #print("value3 = " + event['key3'])
    #return event['key1']  # Echo back the first key value
    #raise Exception('Something went wrong')
    SENDER = "[redacted email]"
    RECIPIENT = event['email']
    CONFIGURATION_SET = "ConfigSet"
    AWS_REGION = "us-east-2"
    SUBJECT = "Contact Us Form Details"
    # The email body for recipients with non-HTML email clients.
BODY_TEXT = "Hello,\r\nPlease see the attached file for a list of customers to contact."

AWS Lambda执行该功能时,它将调用lambda_handler()。按照Python格式,它将执行所有缩进的行,因为它们是函数的一部分。这包括您的print()语句。

但是,从BODY_TEXT = ...行开始,没有缩进。这意味着该代码是“ main”程序的一部分,而是lambda_handler()函数的 not 部分。它将在首次实例化Lambda容器时执行,但在触发函数时 not 会执行。

底线:如果这是您的实际代码,则需要修复缩进。

如果执行lambda时没有收到任何错误,则很可能您没有使用SES API。根据我在代码中看到的内容,您缺少访问密钥ID和秘密访问密钥。尝试按以下方式配置Boto客户端:

client = boto3.client(
    'ses',
    region_name=region,
    aws_access_key_id='aws_access_key_string',
    aws_secret_access_key='aws_secret_key_string'
)

还要确保将lambda部署在与SES相同的区域中。我看到您正在使用us-east-2。 我在文档中看到的另一个差异是,在AWS官方文档中,Destinations实际上是Destination。尝试不使用“ s”。 您还可以粘贴lambda的cloudwatch日志吗?我看到它应该在成功时显示消息ID。是吗?
