错误代码：
class SendFileMailThread(threading.Thread):
"""
异步发送带附件的邮件
"""
def __init__(self, subject, content, recipient_list, file_dict_list=None):
"""
:param subject:
:param content:
:param recipient_list:
:param file_dict_list: [{
"fileName": "",
"filePath": ""
}]
"""
self.read_config = ReadConfig()
self.subject = subject
self.content = content
self.from_email = self.read_config.get_email("EMAIL_HOST_USER")
self.recipient_list = recipient_list
self.file_dict_list = file_dict_list
threading.Thread.__init__(self)
def run(self):
subject = self.subject,
message = self.content,
from_email = self.from_email, # 发件人
recipient_list = self.recipient_list, # 收件人
html_message = self.content,
msg = EmailMultiAlternatives(subject=subject, body=content, from_email=from_email, to=recipient_list)
msg.attach_alternative(content=content, mimetype="text/html")
# add attachment
if self.file_dict_list:
for file_ in self.file_dict_list:
file_name = os.path.basename(file_["fileName"])
# 对文件进行编码处理
b = make_header([(file_name, 'utf-8')]).encode('utf-8')
with open(file_["filePath"], "rb") as fp:
msg.attach(b, fp.read()) # 传入文件名和附件
msg.send()
代码运行后一直报错：
/xxx/xxx/python3.9/site-packages/django/core/mail/message.py", line 96, in sanitize_address
nm, address = addr
ValueError: not enough values to unpack (expected 2, got 1)
最后发现原因是：在def run(self)中， 下列代码赋值后，全都变成了tuple类型。
PS：复制的时候把逗号也复制了，导致赋值错误。
subject = self.subject,
message = self.content,
from_email = self.from_email, # 发件人
recipient_list = self.recipient_list, # 收件人
html_message = self.content,
正确代码：去掉逗号，或者直接用self赋值
