#帮助文档https://github.com/sendgrid/sendgrid-python

1、注册
https://sendgrid.com/注册账号，选择语言类型，创建api-keys。
2、开发环境keys值设定
把创建的keys值放进去。开发环境的shell
Mac
Update the development environment with your SENDGRID_API_KEY (more info here), for example:
echo "export SENDGRID_API_KEY='YOUR_API_KEY'" > sendgrid.env
echo "sendgrid.env" >> .gitignore
source ./sendgrid.env
Sendgrid also supports local environment file .env. Copy or rename .env_sample into .env and update SENDGRID_API_KEYwith your key.
Windows
Temporarily set the environment variable(accesible only during the current cli session):
set SENDGRID_API_KEY=YOUR_API_KEY
Permanently set the environment variable(accessible in all subsequent cli sessions):
setx SENDGRID_API_KEY "YOUR_API_KEY"
Install Package
pip install sendgrid
3、测试代码
# using SendGrid's Python Library
# https://github.com/sendgrid/sendgrid-python
import sendgrid
import os
from sendgrid.helpers.mail import *
def verification():
sg = sendgrid.SendGridAPIClient(apikey=os.environ.get('SENDGRID_API_KEY'))
from_email = Email("604603701@qq.com")
to_email = Email("18804928235@163.com")
subject = "Sending with SendGrid is Fun"
content = Content("text/plain", "and easy to do anywhere, even with Python")
mail = Mail(from_email, subject, to_email, content)
response = sg.client.mail.send.post(request_body=mail.get())
print(response.status_code)
print(response.body)
print(response.headers)
if __name__ == '__main__':
verification()
# import sendgrid
# import os
# sg = sendgrid.SendGridAPIClient(apikey=os.environ.get('SENDGRID_API_KEY'))
# data = {
# "personalizations": [
# {
# "to": [
# {
# "email": "test@example.com"
# }
# ],
# "subject": "Sending with SendGrid is Fun"
# }
# ],
# "from": {
# "email": "test@example.com"
# },
# "content": [
# {
# "type": "text/plain",
# "value": "and easy to do anywhere, even with Python"
# }
# ]
# }
# response = sg.client.mail.send.post(request_body=data)
# print(response.status_code)
# print(response.body)
# print(response.headers)
4、Plan
Plan分为三类：
1）、email api
2）、marketing campaigns（营销活动）
3）、email api 和marketing campaigns（两者一起）
5、SMTP
简单邮件传输协议(Simple Mail Transfer Protocol,SMTP) 是在Internet传输email的事实标准
