如何在使用boto3创建账号后，自动通过邮件邀请IAM用户？

import boto3
from botocore.exceptions import ClientError

iam_client = boto3.client('iam')

def create_iam_user(username):
    try:
        response = iam_client.create_user(UserName=username)
        return response['User']['Arn']
    except ClientError as e:
        print(e.response['Error']['Message'])

def send_invitation_email(username, email):
    try:
        response = iam_client.create_login_profile(
            UserName=username,
            PasswordResetRequired=True
        )
        response = iam_client.create_access_key(UserName=username)
        access_key_id = response['AccessKey']['AccessKeyId']
        secret_access_key = response['AccessKey']['SecretAccessKey']
        
        # 发送包含访问凭证的邀请邮件
        # 这里可以使用自己喜欢的邮件发送方式，比如SMTP或者第三方邮件服务商的API
        # 邮件内容可以包含访问凭证的信息和登录链接等
        # 以下代码仅作示例
        email_subject = 'Invitation to AWS IAM'
        email_body = f'Access Key ID: {access_key_id}\nSecret Access Key: {secret_access_key}\n\nPlease use the following link to login: https://console.aws.amazon.com/iam/'
        send_email(email, email_subject, email_body)
        
        return access_key_id, secret_access_key
    except ClientError as e:
        print(e.response['Error']['Message'])

import smtplib
from email.mime.text import MIMEText

def send_email(to_email, subject, body):
    from_email = 'your_email@example.com'
    smtp_server = 'smtp.example.com'
    smtp_port = 587
    smtp_username = 'your_smtp_username'
    smtp_password = 'your_smtp_password'
    
    msg = MIMEText(body)
    msg['Subject'] = subject
    msg['From'] = from_email
    msg['To'] = to_email
    
    try:
        server = smtplib.SMTP(smtp_server, smtp_port)
        server.starttls()
        server.login(smtp_username, smtp_password)
        server.sendmail(from_email, to_email, msg.as_string())
        server.quit()
        print('Email sent successfully!')
    except Exception as e:
        print('Failed to send email:', str(e))

username = 'new_user'
email = 'new_user@example.com'

user_arn = create_iam_user(username)
if user_arn:
    access_key_id, secret_access_key = send_invitation_email(username, email)
    print('IAM user created successfully!')
    print('Access Key ID:', access_key_id)
    print('Secret Access Key:', secret_access_key)
