我的发展使我能够发送电子邮件。如果我尝试向一张收据发送电子邮件，那没有问题。但是，如果我尝试将同一封电子邮件发送给多个收据，那么我会出错。我不想向多张收据发送电子邮件，我要向每张收据发送一封电子邮件。
我遇到的错误是：
File "/home/josecarlos/Workspace/python/reports/reports/pregame.py",line 22,in __init__
self.send_mail(subject,message,fileName)
File "/home/josecarlos/Workspace/python/reports/reports/report.py",line 48,in send_mail
message = mail.create_message()
File "/home/josecarlos/Workspace/python/reports/com/mail/mail.py",line 100,in create_message
message.attach(MIMEText(self.params["message"],"plain"))
File "/usr/lib/python3.6/email/mime/text.py",line 34,in __init__

要发送电子邮件，我将使用以下方法：
def send_mail(self,subject,fileName):
args = self.params["destiny"]
if self.params["competition"] == COMPETITIONS.LF1 or self.params["competition"] == COMPETITIONS.LF2:
data = SearchData(args,"subscriptors.emails=")
else:
data = SearchDataFIBA(args,"subscriptors.emails=")
emails = data.get_result().getData()
for item in emails:
print(f"Enviamos informe a la cuenta: {item['email']}")
params = {
"from" : "basketmetrics@gmail.com","to" : item["email"],"subject": subject,"message" : message,"fileName" : fileName,"routeFile" : f"output/reports/{self.params['destiny']}/"
}
mail = Mail(params)
message = mail.create_message()
service = mail.get_service()
mail.send_message(service,"basketmetrics@gmail.com",message)
我的应用程序可以安全访问Google帐户。
我不知道如何在没有电子邮件的情况下连续发送超过一封电子邮件
仅发送一封电子邮件的问题。
我做错什么了吗？
编辑我：
要重现该错误，可以使用以下测试代码对其进行测试：
import unittest
import os
from com.mail.mail import Mail
class TestSendMail(unittest.TestCase):
def setUp(self) -> None:
os.chdir(os.path.abspath(os.path.join(os.path.dirname( __file__ ),'..')))
def test_send_mail(self):
message = "¡¡¡Hola!!!\n\nOs enviamos el informe pre partido previo a vuestro próximo partido.\n\nSaludos,\n\nBasketmetrics.com"
subject = "Informe pre partido"
fileName = "name_of_the_file"
emails = [{"email" : "receipt1@gmail.com"},{"email" : "receipt2@gmail.com"}]
for item in emails:
print(f"Enviamos informe a la cuenta: {item['email']}")
params = {
"from" : "sender@gmail.com","routeFile" : "route to the file"
}
mail = Mail(params)
message = mail.create_message()
service = mail.get_service()
mail.send_message(service,"sender@gmail.com",message)
此外，您还必须为自己的值和您自己的Google帐户的文件certificate.json文件更改一些值
编辑II：
我发现它在哪里产生错误，但为什么呢？当我第二次调用班级邮件时出现问题。在那一刻，我将一些参数传递给带有params变量的构造函数。在该变量中，我传递消息的文本。此消息是在循环外部创建的。
如果我在构造函数的params [“ message”]中读取了接收Mail类的邮件的前120个字符：
def __init__(self,params):
'''
:param params: It's a dictionary with these keys:
from: Email account from the email is sended
to: Email account who will receive the email
subject: Subject of the email
message: Message of the email.
game: Next games
'''
self.params = params
print(f"message received: {params['message'][:120]}")
我第一次有了message变量的内容：
message received: ¡¡¡Hola!!!
Os enviamos el informe pre partido previo a vuestro próximo partido.
Saludos,Basketmetrics.com
但是第二次，我应该收到相同的文本！！！但我收到一个错误：
Error
Traceback (most recent call last):
File "/usr/lib/python3.6/unittest/case.py",line 59,in testPartExecutor
yield
File "/usr/lib/python3.6/unittest/case.py",line 605,in run
testMethod()
File "/home/josecarlos/Workspace/python/reports/test/test_send_mail.py",line 26,in test_send_mail
mail = Mail(params)
File "/home/josecarlos/Workspace/python/reports/com/mail/mail.py",line 27,in __init__
print(f"message received: {params['message'][:120]}")
TypeError: unhashable type: 'slice'
如果我阅读所有消息，没有任何限制或字符。我第一次收到可变消息的内容。但是第二次，我收到了一个很大的字符串os字符，这是一个小例子：
lGWFBVZzhQc3pDNWdiNmhnMW1odDZHcmlFZWsyClZvTTBRT1R2dXpWaWlyZkpleS9mZXhtR3V3V2hTV0JjWERtSUNnWENTQVJ1QjdrN1Nzd3BrZ0c1Rkl3MXVDMmNyZk95ZUhySVM1dHQKSUh2T1YvWW1Pd2YzL3B2WEpLaEMza
为什么我收到此字符串而不是message变量的值？
我已经检查过，如果我将消息变量放在for循环内，而不是在循环外...有效！我收到两封邮件！！！
但是，此解决方案没有用，因为我想重用我的代码，并且需要通过变量传递一些值。
那么，为什么第二次我没有收到message变量的值，却收到一长串字符？
如何解决此错误？为什么会发生此错误？
编辑III：
第一次检查我在Mail的构造函数中收到的值的类型是“字符串”：
typeof: <class 'str'>
但是第二次是“ dict”：
typeof: <class 'dict'>
检查self.params [“ message”]的键是：
keys: dict_keys(['raw'])
我一无所知... params [“ message”]可能具有message变量的值，而第二次params [“ message”]却已将其类型修改为raw吗？
编辑IV：
我从...修改了消息变量的内容。
message =“”
致...
message =“” Hola !!! 0x0a0x0aOs enviamos el informatione part part previo previo a vuestropróximopartido.0x0a0x0aSaludos，0x0a0x0aBasketmetrics.com“
但是它不起作用。我有同样的错误。
修改V：
我修改了消息变量的内容。现在，我要发送的不是HTML，而是纯文本。
message = """\
<html>
<head></head>
<body>
<p>
Hi,this is a test!!!
</p>
<p>
Best regards!!!
</p>
</body>
</html>
"""
要发送此消息，您必须在Mail类的create_message方法中修改此指令：
message.attach（MIMEText（self.params [“ message”]，“普通”））
对此：
message.attach（MIMEText（self.params [“ message”]，“ html”））
然后...我也有同样的错误！
我不知道该怎么办...
编辑VI：
最后一次尝试...我修改了消息的文本，删除了诸如“”或“
所以，我的消息变量现在是：
message = "Hello"
我再次修改了电子邮件的格式，从“ html”更改为“普通”
然后...我的第二封电子邮件中有相同的错误！！
这真令人沮丧...：（（（（（（（
