问题描述
在我的一台机器上,当我使用 google 应用程序引擎或 django 时出现错误.
On one of my machines I have the error when I am working with google apps engine or django.
例如:
app.yaml
app.yaml
application: demas1252c
version: 1
runtime: python
api_version: 1
handlers:
- url: /images
static_dir: images
- url: /css
static_dir: css
- url: /js
static_dir: js
- url: /.*
script: demas1252c.py
demas1252c.py
demas1252c.py
import cgi
import wsgiref.handlers
from google.appengine.ext.webapp import template
from google.appengine.ext import webapp
class MainPage(webapp.RequestHandler):
def get(self):
values = {'id' : 10}
self.response.out.write(template.render('foto.html', values))
application = webapp.WSGIApplication([('/', MainPage)], debug = True)
wsgiref.handlers.CGIHandler().run(application)
foto.html
foto.html
<!DOCTYPE html>
<html lang="en">
<head></head>
<body>some</body>
</html>

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe0 in position 0: ordinal not in range(128)
当我在 django 中处理静态文件(没有 gae)时,我有非常相似的错误(有不同的堆栈).
When I am working with static files in django (without gae) I have very similar error (with different stack).
我试图找到错误的原因并在mimetypes.py中添加了代码:
I tried to find the reason of error and added code to mimetypes.py:
print '====='
print ctype
ctype = ctype.encode(default_encoding) # omit in 3.x!
然后我在控制台中收到下一条消息:
Then I get next messages in my console:
=====

=====
video/x-msvideo
=====

在注册表 HKCR/Mime/Database/ContentType/我有五个带有俄文(西里尔文)字母的键.但是我该如何解决这个错误?
In the registry HKCR/Mime/Database/ContentType/ I have five keys with russian (cyrilic) letters. But how can I fix this error?
推荐答案
这是 mimetypes
中的一个错误,由注册表中的错误数据触发.(рєфшю/AMR
根本不是有效的 MIME 媒体类型.)
This is a bug in mimetypes
, triggered by bad data in the registry. (рєфшю/AMR
is not at all a valid MIME media type.)
ctype
是 _winreg.EnumKey
返回的注册表项名称,mimetypes
期望它是一个 Unicode 字符串,但它不是'吨.与 _winreg.QueryValueEx
不同,EnumKey
返回一个字节字符串(直接来自 Windows API 的 ANSI 版本;_winreg
在 Python 2 中不使用Unicode 接口,即使它返回 Unicode 字符串,所以它永远不会正确读取非 ANSI 字符).
ctype
is a registry key name returned by _winreg.EnumKey
, which mimetypes
is expecting to be a Unicode string, but it isn't. Unlike _winreg.QueryValueEx
, EnumKey
returns a byte string (direct from the ANSI version of the Windows API; _winreg
in Python 2 doesn't use the Unicode interfaces even though it returns Unicode strings, so it'll never read non-ANSI characters correctly).
因此,尝试 .encode
失败,出现 UnicodeDecode Error 在将其编码回 ASCII 之前尝试获取 Unicode 字符串!
So the attempt to .encode
it fails with a UnicodeDecodeError trying to get a Unicode string before encoding it back to ASCII!
try:
ctype = ctype.encode(default_encoding) # omit in 3.x!
except UnicodeEncodeError:
pass
mimetypes
中的这些行应该简单地删除.
These lines in mimetypes
should simply be removed.
预计到达时间:添加到错误跟踪器.
