如何在 django 中使用 twilio sendgrid 安排 email？

Question

我目前正在構建一個應用程序，其中包含 email 發送給多個用戶，我可以這樣做，但我想添加一個計划為 email 的功能，例如我正在使用sent_at方法，如下所示：-

設置.py

EMAIL_FROM = 'EMAIL'
EMAIL_API_CLIENT ='XXXXXXXX'

視圖.py

import json
from sendgrid import SendGridAPIClient
from django.conf import settings

message = Mail(from_email=settings.EMAIL_FROM,
               to_emails=selectedphone,
               subject=subject,
               html_content=editor)
message.extra_headers = {'X-SMTPAPI': json.dumps({'send_at': 
                         FinalScheduleTime})}
sg = SendGridAPIClient(settings.EMAIL_API_CLIENT)
response = sg.send(message)
if response.status_code == 202:
     emailstatus = "Accepted"
elif .....
else.....

我也試過message.extra_headers = {'SendAt':FinalScheduleTime}但它也不起作用。

Answer 1

這里的 FinalScheduleTime 是日期時間 object。 sendgrip api 根據文檔接受 UNIX 時間戳。 你可以在這里查看

因此，要將您的日期時間 object 轉換為 unix 時間戳，您可以使用 python 的時間模塊。

scheduleTime = int(time.mktime(FinalScheduleTime.timetuple()))

此外，將 message.extra_headers 替換為 message.send_at。

因此，您的最終代碼將如下所示：

import json
import time
from sendgrid import SendGridAPIClient
from django.conf import settings

message = Mail(from_email=settings.EMAIL_FROM,
               to_emails=selectedphone,
               subject=subject,
               html_content=editor)


scheduleTime = int(time.mktime(FinalScheduleTime.timetuple()))
message.send_at = scheduleTime

sg = SendGridAPIClient(settings.EMAIL_API_CLIENT)
response = sg.send(message)
if response.status_code == 202:
     emailstatus = "Accepted"
elif .....
else.....
