Python implements SSL sending based on QQ mailbox

1. QQ mailbox SSL sending

Get QQ authorization code

The ssl sending method does not use a mailbox password, but an authorization code. The specific steps are as follows:

Verify secret

Copy the 16-digit authorization code

Two, 163 mailbox non-SSL sending

Non-ssl does not need to obtain the authorization code, just configure the email password directly

Three, the problem

3.1 Python failed to send mail through qq mailbox, SMTP:

Problem description: Use qq account and password SSL to send email, error: (535, b'Login Fail. Please enter your authorization code to login. More information in http://service.mail.qq.com/cgi-bin/ help?subtype=1&&id=28&&no=1001256′)

Solution: Turn on the POP3/SMTP service, get the authorization code, and change the mailbox password of the qq source code to the authorization code

3.2 html attachment changed to .bin file suffix

Problem description: Send an attachment in html format, and receive a file with a .bin suffix, as shown in the figure:

Solution: Change att1["Content-Disposition"] ='attachment; filename="' + "interface test report.html" to att1.add_header('Content-Disposition','attachment', filename='interface test report .html')
