Question

我试图在烧瓶内使用sendmail发送一些电子邮件 - 但回来的错误信息有点神秘。

from flask.ext.sendmail import Message
from flask.ext.sendmail import Mail

mail = Mail()
mail.init_app(app)
msg = Message("Hello".encode('utf-8'), sender="xxx@xxx.com".encode('utf-8'), recipients="xxx@xxx.com".encode('utf-8'))
msg.body = "testing"
msg.html = "testing"
mail.send(msg)

问题出现在mail.send（msg）。以下是完整的跟踪：

TypeError: 'str' does not support the buffer interface

可能的罪魁祸首在哪里？

Answer 1

看一下这个例子

>>> 'c' in b'val'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'str' does not support the buffer interface

你得到的是同样的错误，所以不要对你正在使用的str值进行编码。

TypeError：＆＃39; str＆＃39;使用flask sendmail时不支持缓冲区接口
