这是我的脚本，auth_string是正确的，我尝试了这个smtplib.SMTP('smtp.gmail.com:587')和它的工作，imap在我的gmail设置中是活跃的，是的，请帮助我:)

我已经试了3天了，我再也不这样做了:[]
解决方案是我的auth_string是as_base64编码，但imap想要'未编码' auth_string
access_token, expires_in = refresh_authorization(GOOGLE_CLIENT_ID, GOOGLE_CLIENT_SECRET, GOOGLE_REFRESH_TOKEN)auth_string = generate_oauth2_string('---------@gmail.com'， access_token, as_base64=False)
test_imap ('---------@ gmail.com, auth_string)
尝试一步一步:
M = imaplib.IMAP4_SSL('imap.gmail.com')
try:
rv, data = M.login(EMAIL_ACCOUNT, EMAIL_PASSWORD)
except imaplib.IMAP4.error:
print "Login failed."
sys.exit(1)
这将测试IMAP4_SSL与Gmail对您的凭据(没有OAUTH2，所以验证此配置已启用)。
如果这样可以工作，而XOAUTH2不能，那么显然我必须质疑您的声明，即验证字符串是正确的。
例如，您返回的错误似乎指的是mail.google.com的范围，而我期望的是imap.google.com。这是正确的吗?
另外，'XOAUTH2'之后的额外空间是打字错误，还是在原始代码中?这可能会扰乱算法的选择机制。
您可能希望从Google Python XOAUTH2样例代码重新启动并从那里构建。
