利用python自动发邮件

#coding:utf-8
import smtplib
from email.mime.text import MIMEText
from email.header import Header
from email.utils import parseaddr, formataddr
import requests
import time



cityname = '南宁'
#key为聚合平台注册的api接口
key = '*******************'
#发送邮件
sender = '2574******@qq.com'
#接受邮件
receiver = '9801*****@qq.com'
#pswd为发送邮件账号开启smtp服务获得的短匙，不是密码，需要去邮箱设置
pswd = '************'

#通过聚合平台api获得天气预报
def get_weather():
    url = 'http://v.juhe.cn/weather/index?format=2&cityname={cityname}&key={key}'
    data = requests.get(url.format(cityname=cityname,key=key)).json()
    if data['resultcode'] == '200':
        return "今天温度为{temp},{weather},{wind} \n{advice} \n明天的气温为{ttemp}\
        ,{tweather}".format(temp=data['result']['today']['temperature'],
                            weather=data['result']['today']['weather'],
                            wind=data['result']['today']['wind'],
                            advice=data['result']['today']['dressing_advice'],
                            ttemp=data['result']['future'][1]['temperature'],
                            tweather=data['result']['future'][1]['weather'])
    else:
        return "对不起，没有找到该城市的天气数据。"

#发送邮件
def send_email(str):
    message = MIMEText(str,'plain','utf-8')
    message['From'] = Header('每日推送','utf-8').encode()
    message['To'] = Header('you','utf-8').encode()
    message['Subject'] = Header('带给你每天不一样的问候','utf-8').encode()
    smtp_obj = smtplib.SMTP_SSL('smtp.qq.com',465)
    smtp_obj.login(sender,pswd)
    smtp_obj.sendmail(sender,[receiver],message.as_string())

send_email(str)

 

期间遇到一些问题

1,邮箱设置，获得短匙，开始用的邮箱密码一直不对，需要开启以下两个服务

2,使用SMTP_SSL协议，服务器地址为smtp.qq.com

3,发送邮件成功后自动到接收邮件的垃圾箱，百度了下好像没什么解决办法，自己试了下，在垃圾箱中设置这不是垃圾邮件，以后发的邮件就都正常了。
