1、邮件发送  mailsend.py
```
#_*_ coding:utf-8 _*_
import  smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
 
class Sendmail:
 
    local_hostname = ['xxxx']
    msg = MIMEMultipart('related')
 
    def __init__(self,smtp_server,mail_user,mail_pass):
        self.smtp_server = smtp_server
        self.mail_user = mail_user
        self.mail_pass = mail_pass
 
    def mess(self,theme,message):
        Sendmail.msg['Subject'] = theme  # 邮件主题
        html_msg = '''
                <html><head><body>
                <p>%s</p>
                </body></head></html>
            ''' % message
        html = MIMEText(html_msg, 'html', 'utf-8')
        Sendmail.msg.attach(html)
 
    def files(self,path=None,filenames=None):
        if path == None and filenames == None:
            pass
        else:
            files = path + filenames
            att = MIMEText(open(files, 'rb').read(), 'base64', 'utf-8')
            att["Content-Type"] = 'application/octet-stream'
            att["Content-Disposition"] = 'p_w_upload; filename=%s' % filenames
            Sendmail.msg.attach(att)
 
    def send(self,receiver):
        smtp = smtplib.SMTP()
        smtp.connect(self.smtp_server)
        smtp.ehlo(self.local_hostname)  # 使用ehlo指令向smtp服务器确认身份
        smtp.starttls()  # smtp连接传输加密
        smtp.login(self.mail_user, self.mail_pass)
        smtp.sendmail(self.mail_user, receiver, Sendmail.msg.as_string())
        smtp.quit()
if __name__ == "__main__":
    pass
```

2、python flask web框架实现一个http接口
```
#!/usr/bin/env python
#_*_ coding:utf-8 _*_
from flask import Flask,request
import json
from mailsend import Sendmail
app = Flask(__name__)
@app.route('/sendmail' , methods=['GET', 'POST'])
def index():
    if request.method == 'POST':
        jsondata = request.get_data()
        data = json.loads(jsondata)
        s,e,f,r= data['smtpserver'],data['emailsubject'],data['filepath'],data['receivesuser']
        email = Sendmail(s['server'],s['mailuser'],s['mailpasswd'])
        email.mess(e['subject'],e['mess'])
        email.files(f['path'],f['files'])
        print '邮件正在发送...'
        email.send(r['receiver'])
        return '邮件发送成功'
    else:
        return '<h1>只接受post请求！</h1>'
if __name__ =='__main__':
    app.run(debug=True,host='0.0.0.0')
```

3、调用这个接口发送邮件（不管是什么语言调用这个http接口，只要是传送json数据格式即可）
```
#_*_ coding:utf-8 _*_
#POST方式发送邮件数据到smtp http转发接口
import urllib2
import json
def http_post():
    url = 'http://192.168.89.8:5000/sendmail'
    data = {'smtpserver': {'server': 'mail.xxxxx.com', 'mailuser': 'txxtixnrxn@xrxdp.com', 'mailpasswd': '1qaz#EDC'},
            'emailsubject': {'subject': '这次测试做的很晚', 'mess': '现在好困'},
            'filepath': {'path': '/etc/', 'files': 'passwd'},
            'receivesuser': {'receiver': '23456723@qq.com'}}
    headers = {'Content-Type': 'application/json'}
    req = urllib2.Request(url=url, headers=headers, data=json.dumps(data))
    response = urllib2.urlopen(req)
    return response.read()
resp = http_post()
print resp
```
