From Python 3.0 changelog; The StringIO and cStringIO modules are gone. Instead, import the io module and use io.StringIO or io.BytesIO for text and data respectively. From the Python 3 email documentation it can be seen that io.StringIO should be used instead:
from io
import StringIO
from email.generator
import Generator
fp
= StringIO
()
g
= Generator
(fp, mangle_from_
=True, maxheaderlen
=60
)
g.flatten
(msg
)
text
= fp.getvalue
()
从Python 3.0开始,StringIO和cStringIO模块已经取消。通过import io模块代替,分别使用io.String或io.BytesIO处理文本和数据。从Python 3邮件流文档能看到相关实现StringIO的代码为:
from io
import StringIO
from email.generator
import Generator
fp
= StringIO
()
g
= Generator
(fp, mangle_from_
=True, maxheaderlen
=60
)
g.flatten
(msg
)
text
= fp.getvalue
()
