我可以在flask app中使用mailto并发送表单吗？

from flask import Flask, request, render_template
import urllib.parse

app = Flask(__name__)

@app.route('/', methods=['GET', 'POST'])
def index():
    if request.method == 'POST':
        # 获取表单字段的值
        name = request.form.get('name')
        email = request.form.get('email')
        message = request.form.get('message')

        # 构建mailto URI
        mailto_uri = f"mailto:someone@example.com?subject={urllib.parse.quote('新消息')}&body={urllib.parse.quote(f'姓名：{name}\n邮箱：{email}\n消息：{message}')}"
        
        # 重定向到mailto URI
        return redirect(mailto_uri)

    return render_template('index.html')

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