不一致的签名不匹配Amazon S3与django管道，s3boto和存储 [英] Inconsistent SignatureDoesNotMatch Amazon S3 with django-pipeline, s3boto and storages

问题描述

我有2个文件由django-pipeline和s3boto：master.css和master.js一起编译。它们在我的存储区中设置为公共。但是，当我访问它们时，有时会使用master.css，有时候它会与SignatureDoesNotMatch错误。与master.js相同。 Chrome不会发生这种情况。我可能会缺少什么？

编辑：现在也可以在Chrome上发生。

解决方案

发生在我身上...
几个小时找到，但我最终想到了。
证明如果正确的签名是：

ssCNsAOxLf5vA80ldAI3M0CU2％2Bw =

然后AWS将不接受：

ssCNsAOxLf5vA80ldAI3M0CU2 + w =​​

其中唯一的区别是将％2B翻译成'+ '。

S3BotoStorage实际上正确地产生它，但编码发生在url方法的最后一行的CachedFilesMixin（ return unquote（final_url） code>）。
为了解决这个问题，我派生了一个新的CachedFilesMixin来消除损坏（我应该提到我不知道为什么这个unquote首先存在，所以撤消它可能会导致其他问题）

  class MyCachedFilesMixin（CachedFilesMixin）：
 def url（self，* a，** kw）：
s = super 
s = s.encode（'utf-8'，'ignore'）
方案（*），
如果isinstance（s，unicode） ，netloc，path，qs，anchor = urlparse.urlsplit（s）
 path = urllib.quote（path，'/％'）
 qs = urllib.quote_plus（qs，'：& ）
 return urlparse.urlunsplit（（scheme，netloc，path，qs，anchor））
  

我在哪里使用代码，我发现这里。 p>



希望这有帮助...

I have 2 files compiled by django-pipeline along with s3boto: master.css and master.js. They are set to "Public" in my buckets. However, when I access them, sometimes master.css is served, sometimes it errs with SignatureDoesNotMatch. The same with master.js. This doesn't happen on Chrome. What could I be missing?

EDIT: It now happens on Chrome too.

解决方案

Happened to me too... Took a few hours to find, but I figured it out eventually. Turns out that if the right signature is :

ssCNsAOxLf5vA80ldAI3M0CU2%2Bw=

Then AWS will NOT accept:

ssCNsAOxLf5vA80ldAI3M0CU2+w=

Where the only difference is the translation of %2B to '+'.

S3BotoStorage actually yields it correctly but the encoding happens on CachedFilesMixin in the final line of the url method (return unquote(final_url)). To fix it, I derived a new CachedFilesMixin to undo the "damage" (I should mention that I don't know why this unquote exists in the first place, so undoing it might cause other problems)

class MyCachedFilesMixin(CachedFilesMixin):
def url(self, *a, **kw):
    s = super(MyCachedFilesMixin, self).url(*a, **kw)
    if isinstance(s, unicode):
        s = s.encode('utf-8', 'ignore')
    scheme, netloc, path, qs, anchor = urlparse.urlsplit(s)
    path = urllib.quote(path, '/%')
    qs = urllib.quote_plus(qs, ':&=')
    return urlparse.urlunsplit((scheme, netloc, path, qs, anchor))

Where I used the code I found here.

Hope this helps...
