### 开通QQ邮箱的POP3/SMPT协议 ###

打开qq邮箱点击设置，之后点击账户，往下翻，如图。

找到POP3/IMAP/SMTP/Exchange/CardDAV/CalDAV服务，点击开启，开启后会出现一个**授权码**，发送邮件时会用到。

### 安装 ###

发送电子邮件需要安装flask-mail，可以使用pip命令来下载安装。

pip install flask-mail

### 相关配置 ###

app.config["MAIL_SERVER"] = "smtp.qq.com"
    app.config["MAIL_PORT"] = 465  # 设置邮箱端口为465
    app.config["MAIL_USE_SSL"] = True  # QQ邮箱需要开启SSL
    app.config["MAIL_USERNAME"] = "13214213@qq.com"	#发送者邮箱
    app.config["MAIL_PASSWORD"] = ""    #开启POP3/IMAP/SMTP/Exchange/CardDAV/CalDAV服务返回的授权码

### 发送邮件 ###

上述都配置好了之后，定义一个视图函数，编写发送邮件方法，代码如下：

from flask import Flask
    from flask_mail import Mail, Message
    
    app = Flask(__name__)
    
    app.config["MAIL_SERVER"] = "smtp.qq.com"
    app.config["MAIL_PORT"] = 465  # 设置邮箱端口为465
    app.config["MAIL_USE_SSL"] = True  # QQ邮箱需要开启SSL
    app.config["MAIL_USERNAME"] = "xxxxx@qq.com"
    app.config["MAIL_PASSWORD"] = ""    #授权码
    
    mail = Mail(app)
    
    @app.route("/email")
    def emailDemo():
        """
        Message发送邮件信息， sender为发送者邮箱， recipients为接受者邮箱
        """
        message = Message("测试邮件标题122", sender=app.config["MAIL_USERNAME"], recipients=["xxxxxx@qq.com"])
        message.body = "测试邮件的内容122"
    
        # 添加附件
        with app.open_resource("E:\python\Demo.doc") as doc:
            # attach("文件名", "类型", 读取文件）
            message.attach("Demo.doc", 'application/octet-stream', doc.read())
    
        send_email(message)
        return "发送成功"
    
    # 发送邮件
    def send_email(msg):
        with app.app_context():
            mail.send(msg)
    
    if __name__ == "__main__":
        app.run()

运行效果如下
