python使用magic模块进行文件类型识别方法

>>> import magic>>> magic.from_file("testdata/test.pdf")'PDF document, version 1.2'>>> magic.from_buffer(open("testdata/test.pdf").read(1024))'PDF document, version 1.2'>>> magic.from_file("testdata/test.pdf", mime=True)'application/pdf'

>>> f = magic.Magic(uncompress=True)>>> f.from_file('testdata/test.gz')'ASCII text (gzip compressed data, was "test", last modified: Sat Jun 2821:32:52 2008, from Unix)'

>>> f = magic.Magic(mime=True, uncompress=True)>>> f.from_file('testdata/test.gz')'text/plain'
