错误的变量数据类型？

Question

我有 class，它打算从 Git 提交中获取用户名和他的电子邮件：

class BitbucketData(object):

    def get_user_name(self):

        proc = subprocess.Popen("git --no-pager show -s --format='%an'", stdout=subprocess.PIPE)
        committer_name = proc.stdout.read()

        if committer_name:
            return committer_name

    def get_user_email(self):

        proc = subprocess.Popen("git --no-pager show -s --format='%aE'", stdout=subprocess.PIPE)
        committer_email = proc.stdout.read()

        if committer_email:
            return committer_email

然后它用于为用户发送通知（底部是工作版本 - 没有变量 - 所有 sender 和 receiver 数据都明确设置，而不是在变量中 - 他们在这里评论）：

class Services(object):


    def sendmail(self, event):

        repo = BitbucketData()

        #to_address = repo.get_user_email()
        #to_address = 'user@domain.com'
        #to_name = repo.get_user_name()
        #to_name = 'Test user'

        subject = 'Bamboo build and deploy ready'
        sender = 'Bamboo agent <user@domain.com>'

        text_subtype = 'plain'
        message = """
        Hello, {}.

        Your build ready.
        Link to scenario: URL
        Link to build and deploy results: {})

        """.format('Test user', os.environ['bamboo_resultsUrl'])

        msg = MIMEText(message, text_subtype)
        msg['Subject'] = subject
        msg['From'] = sender
        msg['To'] = 'Test user <user@domain.com>'

        smtpconnect = smtplib.SMTP('outlook.office365.com', 587)
        smtpconnect.set_debuglevel(1)
        smtpconnect.starttls()
        smtpconnect.login('user@domain.com', 'password')
        smtpconnect.sendmail('user@domain.com', 'user@domain.com', msg.as_string())
        smtpconnect.quit()

        print('Mail sent')

        print(repo.get_user_email())

问题是 - 如果我使用来自变量的数据（例如 to_address = 'user@domain.com' 或使用 BitbucketData() class 和 to_address = repo.get_user_email() - 我从 Office365 服务器：

...
reply: '250 2.1.0 Sender OK\r\n'
reply: retcode (250); Msg: 2.1.0 Sender OK
send: "rcpt TO:<'user@domain.com'>\r\n"
reply: '501 5.1.3 Invalid address\r\n'
reply: retcode (501); Msg: 5.1.3 Invalid address
...
  File "C:\Python27\lib\smtplib.py", line 742, in sendmail
    raise SMTPRecipientsRefused(senderrs)
smtplib.SMTPRecipientsRefused: {"'user@domain.com'\n": (501, '5.1.3 Invalid address')}

当使用变量时，代码如下所示：

class Services(object):


    def sendmail(self, event):

        repo = BitbucketData()

        to_address = repo.get_user_email()
        #to_address = 'user@domain.com'
        to_name = repo.get_user_name()
        #to_name = 'Test user'
        from_address = 'user@domain.com'

        subject = 'Bamboo build and deploy ready'
        sender = 'Bamboo agent <user@domain.com>'

        text_subtype = 'plain'
        message = """
        Hello, {}.

        Your build ready.
        Link to scenario: URL
        Link to build and deploy results: {})

        """.format(to_name, os.environ['bamboo_resultsUrl'])

        msg = MIMEText(message, text_subtype)
        msg['Subject'] = subject
        msg['From'] = sender
        msg['To'] = to_name

        smtpconnect = smtplib.SMTP('outlook.office365.com', 587)
        smtpconnect.set_debuglevel(1)
        smtpconnect.starttls()
        smtpconnect.login('user@domain.com', 'password')
        smtpconnect.sendmail(from_address, to_address, msg.as_string())
        smtpconnect.quit()

        print('Mail sent')

        print(repo.get_user_email())

我（或 Microsoft SMTP...）在这里做错了什么？

UPD

def sendmail(self, event):

    repo = BitbucketData()
    print(repr(repo.get_user_email()))
    ...

给我：

...
Creating new AutoEnv config
"'user@domain.com'\n"
send: 'ehlo pc-user.kyiv.domain.net\r\n'

您似乎从 git 命令中收到以下输出 -

"'user@domain.com'\n"

您直接将其传递给 smtpconnect，这是导致问题的原因，因为这不是有效的电子邮件地址。您可能需要从中获取实际的字符串。获得它的一种方法是为此使用 ast.literal_eval() 函数。示例 -

>>> import ast
>>> e = ast.literal_eval("'user@domain.com'\n")
>>> print(e)
user@domain.com

从 get_user_email() 函数返回电子邮件时需要执行此操作。很可能 committer_name 也有这个问题，所以你可能也想这样做。

来自 ast.literal_eval() 的文档 -

ast.literal_eval(node_or_string)

Safely evaluate an expression node or a Unicode or Latin-1 encoded string containing a Python literal or container display. The string or node provided may only consist of the following Python literal structures: strings, numbers, tuples, lists, dicts, booleans, and None.
