问题描述
我有一个脚本，它定期向收件人列表发送报告.一切正常，直到今天凌晨 4 点，当我检查收件箱并没有收到报告时.
I have a script which sends periodically reports to a list of recipients. Everything worked fine until today 4 am, when I checked my inbox and the reports didn't come.
通过调试代码:
import smtplib
username="my.user.account@gmail.com"
password="my.correct.password"
server=smtplib.SMTP('smtp.gmail.com',587)
server.ehlo()
server.starttls()
server.ehlo()
server.login(username,password)
#if login worked, it should send a message, but it is not working, so I will suppress this part
server.quit()
我收到以下(旧的)结果:
I receive the following (old known) result:

我尝试过的事情
允许安全性较低的应用程序(如 https://www.google.com/settings/security/lesssecureapps):自从我创建帐户以来，此标志已设置为 true.
Allow less secure apps (as indicated in https://www.google.com/settings/security/lesssecureapps): This flag was set to true since I created the account.
禁用验证码(如 https://accounts.google.com/DisplayUnlockCaptcha 中所示):多次访问此 URL.没有运气.
Disable Captcha (as indicated in https://accounts.google.com/DisplayUnlockCaptcha): Visited this URL several times. No luck.
通过浏览器登录:在任何计算机上通过任何 Internet 浏览器登录时，它都可以正常工作，尽管在第一次我必须插入发送到帐户的辅助电话的代码.
Login via browser: It works fine, when logging via any Internet Browser from any computer, although in the first times I had to insert a code sent to the account's recovery phone.
我遇到了其他可以尝试的方法，但我不确定它是否可行:
I came across other things I could try, but I am not sure it could work:
- 特定应用密码
- Oauth2
- 更改或重置密码
我可能会尝试 oauth2，但它需要更改我的代码，由于服务器中的一些限制，我想避免这种情况.
I will probably try oauth2, however it would require a change in my code, which I want to avoid due to some restrictions in the server.
推荐答案
我已经使用 Google Gmail API 解决了这个问题.谷歌似乎已经阻止或限制了通过未知设备登录我的帐户，因为我只能通过浏览器登录，并且在我确认了电话号码和短信发送的代码之后.
I have solved this using the Google Gmail API. It seems Google has either blocked or limited logins for my account through unknown devices, as I could login only via the browser and after I confirmed the telephone number and an code sent by SMS.
所以我决定放弃使用 smtplib 并使用 Google 用于 Gmail 的 API 实现访问:https://developers.google.com/api-client-library/python/https://developers.google.com/gmail/api/guides/sending
So I decided to give up using smtplib and implemented the access using the API Google uses for Gmail: https://developers.google.com/api-client-library/python/ https://developers.google.com/gmail/api/guides/sending
希望这对遇到此问题的其他人有所帮助.
Hope this helps other who had trouble with this issue.
