折腾：
后，突然想到，Python中估计会有MIME方面的库的：
估计给定文件名后缀，就可以得到MIME
搜：
python MIME lib
看起来很好用：
1 2 3 | >>> import mime>>> mime.MimeType.fromName('myfile.png')<MimeType: image/png> |
->
mime库看起来也还可以。
1 2 3 4 5 6 | # For MIME types>>> import magic>>> mime = magic.Magic(mime=True)>>> mime.from_file("testdata/test.pdf")'application/pdf'>>> |
抽空去试试。
这样就不用自己手动整理出：
后缀名 对应的MIME type了。
先去安装：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | ➜ 英语资源 pip install mimeCollecting mime Downloading mime-0.1.0.tar.gzCollecting future (from mime) Downloading future-0.16.0.tar.gz (824kB) 100% |████████████████████████████████| 829kB 757kB/sBuilding wheels for collected packages: mime, future Running setup.py bdist_wheel for mime ... done Stored in directory: /Users/crifan/Library/Caches/pip/wheels/ad/c5/51/fb656ef3fd92b30ea9821aa57e4f106232aeb7debfd7d6b11e Running setup.py bdist_wheel for future ... done Stored in directory: /Users/crifan/Library/Caches/pip/wheels/c2/50/7c/0d83b4baac4f63ff7a765bd16390d2ab43c93587fac9d6017aSuccessfully built mime futureInstalling collected packages: future, mimeSuccessfully installed future-0.16.0 mime-0.1.0 |
然后去试试效果：
结果代码：
1 2 3 4 | import mimefileMimeType = mime.MimeType.fromName(curAudioFullFilename)logging.info("fileMimeType=%s", fileMimeType) |
出错：
1 2 3 4 5 6 7 8 9 10 | Traceback (most recent call last): File "/Applications/PyCharm.app/Contents/helpers/pydev/pydevd.py", line 1668, in <module> main() File "/Applications/PyCharm.app/Contents/helpers/pydev/pydevd.py", line 1662, in main globals = debugger.run(setup['file'], None, None, is_module) File "/Applications/PyCharm.app/Contents/helpers/pydev/pydevd.py", line 1072, in run pydev_imports.execfile(file, globals, locals) # execute the script File "/Users/crifan/dev/dev_root/company/xxx/projects/mongodb/saveLocalData/pymongoTest.py", line 70, in <module> fileMimeType = mime.MimeType.fromName(curAudioFullFilename)AttributeError: 'module' object has no attribute 'MimeType' |
而写代码期间，也发现了：
结果：
1 | fileMimeType = mime.MIMETypes.load_from_file(curAudioFullFilename) |
错误：
1 2 3 4 5 6 7 8 9 10 11 12 13 | 2018/03/29 05:57:12 LINE 59 INFO ottoTheCatFile=NoneTraceback (most recent call last): File "/Applications/PyCharm.app/Contents/helpers/pydev/pydevd.py", line 1668, in <module> main() File "/Applications/PyCharm.app/Contents/helpers/pydev/pydevd.py", line 1662, in main globals = debugger.run(setup['file'], None, None, is_module) File "/Applications/PyCharm.app/Contents/helpers/pydev/pydevd.py", line 1072, in run pydev_imports.execfile(file, globals, locals) # execute the script File "/Users/crifan/dev/dev_root/company/xxx/projects/mongodb/saveLocalData/pymongoTest.py", line 70, in <module> fileMimeType = mime.MIMETypes.load_from_file(curAudioFullFilename) File "/usr/local/lib/python2.7/site-packages/mime/mime_types.py", line 49, in load_from_file __parsing_error(type_file, index, line, RuntimeError)NameError: global name '_MIMETypes__parsing_error' is not defined |
再去试试：
发现这个也是：
pip install mime
靠，两个mime都是一样的名字啊
算了，根据：
的“python-mime – A proper MIME type library for Python”
去安装：
python-mime
1 2 3 4 | ➜ 英语资源 pip install python-mimeCollecting python-mime Could not find a version that satisfies the requirement python-mime (from versions: )No matching distribution found for python-mime |
找不到。
放弃。
继续用：
1 | fileMimeType = mime.Types.of(curAudioFullFilename)[0].content_type |
结果可以了：
1 | audio/mpeg |
【总结】
最后是去用：
的库：
1 | pip install mime |
后，用：
1 2 3 | import mimefileMimeType = mime.Types.of(curAudioFullFilename)[0].content_type |
即可从文件名：
‘。。。/音频/Lots of Hearts.mp3′
中提取出来：
‘audio/mpeg’
