SuspiciousOperation使用SORL縮略圖

我有訪問和操縱代表用戶的幾個服務器的文件系統（例如/ FS01，/ FS02等）一個Django web應用程序。我想向用戶展示這些文件系統上的圖像縮略圖，並認爲sorl-thumbnail是實現它的方式。SuspiciousOperation使用SORL縮略圖

看來，雖然這些圖像必須在MEDIA_ROOT爲SORL-縮略圖創建縮略圖。我MEDIA_ROOT是/Users/me/Dev/MyProject/myproj/media，所以此工程：

path = "/Users/me/Dev/MyProject/myproj/media/pipe-img/magritte-pipe-large.jpg" 
try: 
    im = get_thumbnail(path, '100x100', crop='center', quality=99) 
except Exception, e: 
    exc_type, exc_obj, exc_tb = sys.exc_info() 
    print "Failed getting thumbnail: (%s) %s" % (exc_type, e) 
print "im.url = %s" % im.url

它創建縮略圖並打印im.url，如我所期待。但是，當我改變path到：

path = "/fs02/dir/ep340102/foo/2048x1024/magritte-pipe-large.jpg"

它失敗：

Failed getting thumbnail: (<class 'django.core.exceptions.SuspiciousOperation'>) 
Attempted access to '/fs02/dir/ep340102/foo/2048x1024/magritte-pipe-large.jpg' denied.

有沒有辦法解決這個問題的方法嗎？我可以使用sorl-thumbnail創建縮略圖，因爲我想在這些其他文件系統下創建縮略圖（例如/ fs01，/ fs02，/ fs03等）？有更好的方法嗎？

更新。以下是完整的堆棧跟蹤：

我認爲你應該使用相對路徑'settings.MEDIA_ROOT'代替絕對路徑。但是完整的堆棧跟蹤對於做出準確的答案會很有用。 – jpic 2013-02-11 21:21:08

我只是爲了說明目的而包括實際路徑。我可以將'path'設置爲'os.path.join（settings.MEDIA_ROOT，「pipe-img/magritte-pipe-large.jpg」）'。好主意 - 我現在將添加完整的堆棧跟蹤。 – mobopro 2013-02-11 21:44:26

嘗試''pipe-img/magritte-pipe-large.jpg「'而不是'os.path.join（settings.MEDIA_ROOT，」pipe-img/magritte-pipe-large.jpg「）''。我認爲它會自動生成絕對路徑。 – jpic 2013-02-12 09:02:36

的SuspiciousOperation是FileSystemStorage.path（）位置：

def path(self, name): 
try: 
    path = safe_join(self.location, name) 
except ValueError: 
    raise SuspiciousFileOperation("Attempted access to '%s' denied." % name) 
return os.path.normpath(path)

它起源於safe_join（）具有這種測試：

if (not normcase(final_path).startswith(normcase(base_path + sep)) and 
...

這意味着計算出的文件名必須存在於配置的縮略圖存儲器中。默認情況下，settings.THUMBNAIL_STORAGE是settings.DEFAULT_FILE_STORAGE，它是將文件存儲在settings.MEDIA_ROOT中的FileSystemStorage。

您應該能夠通過定義存儲類用於縮略圖不同的存儲路徑：

from django.core.files.storage import FileSystemStorage 

class ThumbnailStorage(FileSystemStorage): 
    def __init__(self, **kwargs): 
     super(ThumbnailStorage, self).__init__(
      location='/fs02', base_url='/fs02')

然後在settings.py

THUMBNAIL_STORAGE = 'myproj.storage.ThumbnailStorage'

您還需要確保東西在服務/ fs02在該URL：

if settings.DEBUG: 
    patterns += patterns('', 
     url(r'^fs02/(?P<path>.*)$', 'django.views.static.serve', 
      {'document_root': '/fs02'}))

請注意，您的縮略圖將被創建爲/ fs 02 /緩存/ ...每默認THUMBNAIL_PREFIX

我最終走了一個不同於sorl-thumbnail的方向，但是當我有這個答案的時候，我會用它。看起來很對我！ – mobopro 2013-08-29 15:36:00

用下面的命令得到了什麼？

ls -la /fs02/dir/ep340102/foo/2048x1024/

不，我確定文件是可以訪問的......'-rw-rw-rw- @ 1 dylan staff 82222 Feb 6 06:28 magritte-pipe-large.jpg'。我一直在挖掘storage.py代碼，並認爲我有一個想法是什麼。更多... – mobopro 2013-02-12 04:26:08

ls -la/fs02？我有一個文件可以訪問的情況下，但不是其目錄的鏈接... – 2013-02-12 05:46:56

我做到了通過提供一個絕對的URL，而不是像這樣：

from sorl.thumbnail import get_thumbnail 
from django.contrib.staticfiles.storage import staticfiles_storage 

image_url = staticfiles_storage.url('image.jpg') 
thumbnail = get_thumbnail(image_url, '100x100')
