Flask中怎么实现电子邮件发送

在Flask中实现电子邮件发送可以使用Python的smtplib库。下面是一个简单的例子：

from flask import Flask, request
import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart

app = Flask(__name__)

def send_email(subject, message, to_email):
    from_email = 'your_email@example.com'
    password = 'your_password'

    msg = MIMEMultipart()
    msg['From'] = from_email
    msg['To'] = to_email
    msg['Subject'] = subject

    msg.attach(MIMEText(message, 'plain'))

    server = smtplib.SMTP('smtp.example.com', 587)
    server.starttls()
    server.login(from_email, password)
    text = msg.as_string()
    server.sendmail(from_email, to_email, text)
    server.quit()

@app.route('/send_email', methods=['POST'])
def send_email_route():
    data = https://www.yisu.com/ask/request.get_json()'subject']
    message = data['message']
    to_email = data['to_email']

    send_email(subject, message, to_email)

    return 'Email sent successfully!'

if __name__ == '__main__':
    app.run()

在上面的例子中，我们定义了一个send_email函数来发送电子邮件。然后我们在Flask应用中创建了一个路由/send_email，通过POST请求发送邮件的主题、内容和收件人邮箱地址。当接收到请求时，我们调用send_email函数发送电子邮件。
