python - LookupError：未知编码：-

问题描述

我一直收到此错误，不知道如何解决。有任何想法吗？

填充物，因为我必须添加更多细节并且不知道要写什么所以忽略这个

import smtplib, ssl
from email.message import EmailMessage
import mysql.connector


mydb = mysql.connector.connect(
  host='localhost',
  database='notgettingthis',
  user='neitherthis',
  password='verynicepass'
)

cursor = mydb.cursor(buffered=True)

food1m = "SELECT * FROM thing WHERE fhfhfhf='e' ORDER BY RAND() LIMIT 4;"
cursor.execute(thing)
thing1 = cursor.fetchone()[1]
thing2 = cursor.fetchone()[1]
thing3 = cursor.fetchone()[1]
thing4 = cursor.fetchone()[1]


msg1 = EmailMessage()
msg1.set_content("""blablablablablablablabla:

-""", str(thing1), """
-""", str(thing2), """
-""", str(thing3), """
-""", str(thing4)
)
msg1["Subject"] = "subject"
msg1["From"] = "example@gmail.com"
msg1["To"] = "exampple@gmail.com"

context = ssl.create_default_context()
with smtplib.SMTP("smtp.example.com", port=587) as smtp:
    smtp.starttls(context=context)
    smtp.login(msg1["From"], "pass")
    smtp.send_message(msg1)

完整的错误和回溯：

    lines = string.encode(charset).splitlines()
LookupError: unknown encoding:

标签： python

解决方案

该set_content方法感知所有这些：

"""blablablablablablablabla:

-""", str(thing1), """
-""", str(thing2), """
-""", str(thing3), """
-""", str(thing4)

作为单独的参数，因为它们用逗号分隔。我假设您想将所有这些连接在一起的参数发送到msg参数（请参阅this）。

改变

msg1.set_content("""blablablablablablablabla:

-""", str(thing1), """
-""", str(thing2), """
-""", str(thing3), """
-""", str(thing4)
)

至

msg1.set_content("""blablablablablablablabla:

-""" + str(thing1) + """
-""" + str(thing2) + """
-""" + str(thing3) + """
-""" + str(thing4)
)
