15.6.1. 开源yagmail发送邮件 ¶

安装

pip install -U yagmail -i "https://pypi.doubanio.com/simple/"       #使用国内的pip源安装yagmail

使用示例：¶

#!/usr/bin/env python
# -*- coding:utf8 -*-
# auther; 18793
# Date：2020/3/21 9:36
# filename: yagmail01.py

import yagmail

yag = yagmail.SMTP(user='1879324764@qq.com', password="xxxxxxxxx", host='smtp.qq.com', port=25)

content = ['This is the body , and here is just text',
           'You can find an image file adn a pdf file attached.',
           'iphone6_pic.jpg', 'redbooks.pdf']

yag.send("962057147@qq.com", 'This mail come from yagmail', content)
yag.close()

使用上下文管理器优化关闭连接的逻辑，使代码更加清晰易懂。

#!/usr/bin/env python
# -*- coding:utf8 -*-
# auther; 18793
# Date：2020/3/21 9:36
# filename: yagmail02.py

import yagmail

content = ['This is the body , and here is just text',
           'You can find an image file adn a pdf file attached.',
           'iphone6_pic.jpg', 'redbooks.pdf']

with yagmail.SMTP(user='1879324764@qq.com', password="tpuvxqftwjujeaja", host='smtp.qq.com', port=25) as yag:
    yag.send("962057147@qq.com", 'This mail come from yagmail', content)

配置文件信息

[root@k8s-master ~]# cat ~/.emcli.cnf
[DEFAULT]
smtp_server = smtp.qq.com
smtp_port = 25
username = 1879324764@qq.com
password = tpuvxqftwjujeaja

emcli的功能实现 ¶

解析命令行参数¶

def get_argparse():
    parser = argparse.ArgumentParser(description='A email client in terminal')
    parser.add_argument('-s', action='store', dest='subject', required=True, help='specify a subject (must be in quotes if it has spaces)')
    parser.add_argument('-a', action='store', nargs='*', dest='attaches', required=False, help='attach file(s) to the message')
    parser.add_argument('-f', action='store', dest='conf', required=False, help='specify an alternate .emcli.cnf file')
    parser.add_argument('-r', action='store', nargs='*', dest='recipients', required=True, help='recipient who you are sending the email to')
    parser.add_argument('-v', action='version', version='%(prog)s 0.2')
    return parser.parse_args()

解析配置文件内容¶

def get_config_file(config_file):
    if config_file is None:
        config_file = os.path.expanduser('~/.emcli.cnf')
    return config_file


def get_meta_from_config(config_file):
    config = ConfigParser.SafeConfigParser()

    with open(config_file) as fp:
        config.readfp(fp)

    meta = Storage()
    for key in ['smtp_server', 'smtp_port', 'username', 'password']:
        try:
            val = config.get('DEFAULT', key)
        except (ConfigParser.NoSectionError, ConfigParser.NoOptionError) as err:
            logger.error(err)
            raise SystemExit(err)
        else:
            meta[key] = val

    return meta

使用yagmail发送电子邮件¶

def send_email(meta):
    content = get_email_content()
    body = [content]
    if meta.attaches:
        body.extend(meta.attaches)

    with yagmail.SMTP(user=meta.username, password=meta.password,
                      host=meta.smtp_server, port=int(meta.smtp_port)) as yag:
        logger.info('ready to send email "{0}" to {1}'.format(meta.subject, meta.recipients))
        ret = yag.send(meta.recipients, meta.subject, body)

log日志打印的辅助函数¶

import logging


def get_logger(log_level=logging.INFO):
    logger = logging.getLogger(__name__)
    logger.setLevel(log_level)

    formatter = logging.Formatter("%(asctime)s [emcli] [%(levelname)s] : %(message)s", "%Y-%m-%d %H:%M:%S")

    handler = logging.StreamHandler()
    handler.setFormatter(formatter)

    logger.handlers = [handler]

    return logger

使用setuptools打包源码¶

setup.py

#!/usr/bin/env python
# coding: utf-8
from setuptools import setup

setup(
    name='emcli',
    version='0.2',
    author='Mingxing LAI',
    author_email='me@mingxinglai.com',
    url='https://github.com/lalor/emcli',
    description='A email client in terminal',
    packages=['emcli'],
    install_requires=['yagmail'],
    tests_require=['nose', 'tox'],
    entry_points={
        'console_scripts': [
            'emcli=emcli:main',
        ]
    }
)

本机安装和运行

python setup.py install

如果要安装到其他机器上

python setup.py sdist

会在emcli\dist 的目录下生成一个emcli-0.2.tar.gz的文件

使用twine上传到PyPi¶

在Python生态中，工程师已经习惯了使用pip 命令安装软件包。为了让最终用户可以使用pip 命令安装emcli 项目, 我们需要将emcli发布到PyPI(http://pypi.python.org)上。

因此，我们需要在PyPI上注册一个账号。账号注册完成以后,在HOME 目录下创建一个.pypirc文件，并在文件中填人PyPi的用户名和密码：

[pypi]
username:<your username>
password:<your password>

配置好用户名和密码以后，还需要安装一个名为twine的小工具。

是一个将软件包上传到PyPI 上的工具。如下所示：

pip install twine

使用twine将emcli上传到PyPI ：

twine dist/*

上传完成以后，任何人都可以在自己的电脑上使用pip命令安装我们的命令行邮件客户端。
