Cherrypy文件上传非ASCII文件名乱码问题解决

Cherrypy 版本： 18.0.1

由于某些特殊原因(可能是与标准兼容的问题)，Cherrypy对上传文件的原文件名使用 ISO-8859-1 编码方式解码，导致非 ASCII 的文件名显示为乱码。

解决的方式也很简单，只需要对文件名使用 ISO-8859-1 编码然后在使用 UTF-8 重新解码即可。

以下是一个完整的例子：

 1 from os import makedirs
 2 from os.path import dirname, join as pathjoin, exists as pathexists
 3 from cherrypy import expose, quickstart, request, config
 4 
 5 HERE = dirname(__file__)
 6 UPLOAD_FOLDER = pathjoin(HERE, 'uploads')
 7 
 8 
 9 def repaire_filename(filename):
10     return filename.encode('ISO-8859-1').decode('utf-8', 'replace')
11 
12 
13 def save_uploadfiles(files, folder=UPLOAD_FOLDER):
14     if not pathexists(folder):
15         makedirs(folder)
16     if not isinstance(files, list):
17         files = [files]
18     for upload in files:
19         if not upload.filename:
20             continue
21         basename = repaire_filename(upload.filename)
22         filename = pathjoin(folder, basename)
23         with upload.file as upload_file, open(filename, 'wb') as to_save:
24             while True:
25                 buf = upload_file.read(8192)
26                 if not buf:
27                     break
28                 to_save.write(buf)
29 
30 
31 @expose
32 def index(upload_files=None):
33     if request.method == 'POST':
34         save_uploadfiles(upload_files)
35     return '''
36 <form method="POST" enctype="multipart/form-data">
37 <div><input name="upload_files" type="file" /></div>
38 <div><input name="upload_files" type="file" /></div>
39 <div><input name="upload_files" type="file" /></div>
40 <input type="submit" />
41 </form>
42 '''

46     quickstart(index)
