背景
做SEO会涉及很多数据，旁边NB的同事用公司的VPS实现了简单的自动化SEO数据监控系统，用来监控每天的抓取数据，并用formail发送邮件，然后用gmail筛选条件转
mail python
发给我。但后来忽然发现收不到邮件了（可能跟伪造发件邮箱有关），并且有些频道需要自己去设置，于是就打算自己搞一下。formail不会用，python还算会一点，于是就瞅上了smtplib。
代码
其实smtplib很简单，发送常规邮件的核心代码也只有3,4行。完整代码请见：

其实核心代码也就3行，其他都是固定设置：

1 2 3 |
<span class="n">s</span> <span class="o">=</span> <span class="n">smtplib</span><span class="o">.</span><span class="n">SMTP</span><span class="p">(</span><span class="n">host</span><span class="p">,</span> <span class="n">port</span><span class="p">)</span> <span class="n">s</span><span class="o">.</span><span class="n">login</span><span class="p">(</span><span class="n">sender</span><span class="p">,</span> <span class="n">pwd</span><span class="p">)</span> <span class="n">s</span><span class="o">.</span><span class="n">sendmail</span><span class="p">(</span><span class="n">sender</span><span class="p">,</span> <span class="n">receiver</span><span class="p">,</span> <span class="n">msg</span><span class="o">.</span><span class="n">as_string</span><span class="p">())</span> |
另外注意下，如果是使用SSL发送，需要使用SMTP_SSL，其他都是一样的（这是个坑，之前搞了好久都不成功，后来才发现是这个问题）。
升级
当初搞了3个脚本，每个脚本里面都有一坨这些代码，于是想到了封装。只要封装一下，以后再使用的时候只需要import+一行代码就可以了。于是就有了下面的代码：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
<span class="k">def</span> <span class="nf">sm</span><span class="p">(</span><span class="n">receiver</span><span class="p">,</span> <span class="n">title</span><span class="p">,</span> <span class="n">body</span><span class="p">):</span> <span class="n">host</span> <span class="o">=</span> <span class="s">'smtp.163.com'</span> <span class="n">port</span> <span class="o">=</span> <span class="mi">25</span> <span class="n">sender</span> <span class="o">=</span> <span class="s">'alexkh3@163.com'</span> <span class="n">pwd</span> <span class="o">=</span> <span class="s">'XXXXXX'</span> <span class="n">msg</span> <span class="o">=</span> <span class="n">MIMEText</span><span class="p">(</span><span class="n">body</span><span class="p">,</span> <span class="s">'html'</span><span class="p">)</span> <span class="n">msg</span><span class="p">[</span><span class="s">'subject'</span><span class="p">]</span> <span class="o">=</span> <span class="n">title</span> <span class="n">msg</span><span class="p">[</span><span class="s">'from'</span><span class="p">]</span> <span class="o">=</span> <span class="n">sender</span> <span class="n">msg</span><span class="p">[</span><span class="s">'to'</span><span class="p">]</span> <span class="o">=</span> <span class="n">receiver</span> <span class="n">s</span> <span class="o">=</span> <span class="n">smtplib</span><span class="o">.</span><span class="n">SMTP</span><span class="p">(</span><span class="n">host</span><span class="p">,</span> <span class="n">port</span><span class="p">)</span> <span class="n">s</span><span class="o">.</span><span class="n">login</span><span class="p">(</span><span class="n">sender</span><span class="p">,</span> <span class="n">pwd</span><span class="p">)</span> <span class="n">s</span><span class="o">.</span><span class="n">sendmail</span><span class="p">(</span><span class="n">sender</span><span class="p">,</span> <span class="n">receiver</span><span class="p">,</span> <span class="n">msg</span><span class="o">.</span><span class="n">as_string</span><span class="p">())</span> <span class="k">print</span> <span class="s">'The mail named </span><span class="si">%s</span><span class="s"> to </span><span class="si">%s</span><span class="s"> is sended successly.'</span> <span class="o">%</span> <span class="p">(</span><span class="n">title</span><span class="p">,</span> <span class="n">receiver</span><span class="p">)</span> |
这样以后只要import进来，然后sm(receiver, title, body)就OK了。
附表 - 常用邮箱发件服务器及端口
| 邮箱品牌 | 发件服务器 | 非SSL协议端口 | SSL协议端口 |
|---|---|---|---|
| 163 | smtp.163.com | 25 | 465/587 |
| gmail | smtp.gmail.com | - | 465 |
| smtp.qq.com | 25 | 465/587 |
后记
- 好久没发博了，markdown和farbox的语法都忘了，惭愧啊；
- 家里装修，加上工作忙乱，一直没发文；另一方面也不知道写啥，好像忽然没了信心；
- 希望以后能多分享点，虽然很初级，但自己水平就是这样啊；
- 因为没有附件，所以代码部分很简单，如果带了附件，推荐下Envelope，描述里说是
Mailing for human beings(模仿requests)。
