代碼來自<Flask Web開發 基于Python的Web應用開發實戰>書上的第六章中的示例,github版本是6b,代碼獲取方式如下：

終端輸入：

git clone https://github.com/miguelgrinberg/flasky.git

git checkout 6b

?

測試場景：

發送方是163郵箱

接收方是qq郵箱

?

為了方便運行,hello.py修改如下:

以上的注釋中標注了所有需要修改，以及相對于github上面的代碼而言，需要增加的部分

kilport函數是根據上次運行代碼時的端口關閉進程，這樣運行代碼時就不用手動在終端關閉進程來釋放端口了，方便調試使用。

注意必須是view plain中才能復制以上代碼，因為博客顯示中會把三個引號'''顯示成5個引號'''''

請記得.bashrc中增加上面注釋中提到的四行,然后運行方法是(注意上面的flask_script相關的不能刪除,否則下面的shell上下文環境就沒有了):

?

運行方法如下:

python hello.py shell

>>> from flask.ext.mail import Message
>>> msg = Message('test subject', sender='appleyuchi@163.com', recipients=['XXXXXXx@qq.com'])
>>> msg.body = 'text body'
>>> msg.html = '<b>HTML</b>'
>>> with app.app_context():
...? ? ?mail.send(msg)

?

總結：如果使用的發送和接收郵箱類型不變的話，那么只要修改：

.bashrc中的三處163郵箱+一處qq郵箱+一處163郵箱密碼+

開啟發送端的SMTP+接收端郵箱的POP即可

最終實驗成功的標志是在接收端的qq郵箱里面收到郵件.
