【重复】SendGrid-Python 报错 TypeError: Object of type Email is not JSON serializable

HelloFlask Flask Web 开发实战

import sendgrid
import os
from sendgrid.helpers.mail import *


def send_email(subject, to, body):
    sg = sendgrid.SendGridAPIClient(api_key=os.getenv('SENDGRID_API_KEY'))
    from_email = Email('andyforever0108@outlook.com')
    to_email = Email(to)
    content = Content("text/plain", body)
    mail = Mail(from_email, subject, to_email, content)
    response = sg.client.send.post(request_body=mail.get())

在自己的项目中使用这个函数的时候遇到

TypeError: Object of type Email is not JSON serializable

我用的是 Outlook.com，请问是Outlook.com的格式问题吗？

发帖前建议先搜索：

另外你的标题也太简陋了，下次拜托写一个包含关键信息的标题，比如「sendgrid 发送邮件报错TypeError: Object of type Email is not JSON serializable」。

不好意思，初来乍到

对了，建议用示例程序的依赖文件来一次安装所有依赖：

$ pip install -r requirements.txt

或：

$ pipenv install --dev

这样所有依赖的版本都会对应书里介绍的版本。
