使用Azure存储SDK使用Django（并且完全取消对Django的存储器依​​赖） [英] Using Azure Storage SDK with Django (and removing dependency on django-storages entirely)

问题描述

有没有人有使用 Azure的存储直接与Django的？我问，因为我目前正在建立的Azure云存储为我的Django应用程序（托管在Azure虚拟机与Ubuntu OS）和 Django的货仓似乎并不与Azure存储SDK接口正确（已知问题：<一href=\"http://stackoverflow.com/questions/33151766/using-azure-as-a-storage-backend-for-django-using-django-storages\">see这里）。此修复程序上市给我的Django的版本对我来说是行不通为＆lt; 1.6.2。

Does anyone have any tips on using azure-storage directly with Django? I ask because currently I'm trying to set up Azure Cloud Storage for my Django app (hosted on Azure VM with Ubuntu OS), and django-storages doesn't seem to be interfacing with Azure Storage SDK correctly (known issue: see here). The fix listed there won't work for me given my Django version is < 1.6.2.

因此​​我需要直接与Django中使用Azure的存储。有没有人设置？我需要保存图片和的MP3 的云存储。

Thus I'll need to use Azure-storage directly with Django. Has anyone set that up before? I need to save images and mp3s on the Cloud Storage.

目前，在我的models.py，我有：

Currently, in my models.py, I have:

def upload_to_location(instance, filename):
    try:
        blocks = filename.split('.') 
        ext = blocks[-1]
        filename = "%s.%s" % (uuid.uuid4(), ext)
        instance.title = blocks[0]
        return os.path.join('uploads/', filename)
    except Exception as e:
        print '%s (%s)' % (e.message, type(e))
        return 0

class Photo(models.Model):
    description = models.TextField(validators=[MaxLengthValidator(500)])
    submitted_on = models.DateTimeField(auto_now_add=True)
    image_file = models.ImageField(upload_to=upload_to_location, null=True, blank=True )

然后 Django的货仓和博托拿剩下的事情。然而，当我勾Django的存储器与Azure的云存储，我得到以下错误：

And then django-storages and boto take care of the rest. However, when I hook django-storages up with Azure Cloud Storage, I get the following error:

Exception Value:      
'module' object has no attribute 'WindowsAzureMissingResourceError'

Exception Location:     
/home/mhb11/.virtualenvs/myvirtualenv/local/lib/python2.7/site-packages/storages/backends/azure_storage.py in exists, line 46

而code的相关片段是：

And the relevant snippet of the code is:

def exists(self, name):
    try:
        self.connection.get_blob_properties(
            self.azure_container, name)
    except azure.WindowsAzureMissingResourceError:
        return False
    else:
        return True

似乎对Azure的容器连接失败。在我的settings.py，我有：

Seems that the connection to the Azure container is failing. In my settings.py, I have:

    DEFAULT_FILE_STORAGE = 'storages.backends.azure_storage.AzureStorage'
    AZURE_ACCOUNT_NAME = 'photodatabasestorage'
    AZURE_ACCOUNT_KEY = 'something'
    AZURE_CONTAINER = 'somecontainer'

如前所述，我需要完全绕过Django的存储器解决方案，仅仅依靠Azure存储SDK来完成这项工作。

As described earlier, I need a solution that bypasses django-storages entirely, and just relies on Azure Storage SDK to get the job done.

的注：向我要了解更多信息的情况下，你需要它的

推荐答案

我们可以直接使用 Azure-在Django的存储蟒蛇SDK应用就像普通的Python应用程序使用SDK。你可以参考<一个href=\"https://azure.microsoft.com/en-us/documentation/articles/storage-python-how-to-use-blob-storage/\"相对=nofollow>入门官方指南。

We can directly use Azure-Storage python SDK in the Django apps just like using the sdk in common python applications. You can refer to official guide for getting started.

下面是在Django应用程序测试code片断：

Here is the test code snippet in the Django app:

def putfiles(request):
blob_service = BlobService(account_name=accountName, account_key=accountKey)
PROJECT_ROOT = path.dirname(path.abspath(path.dirname(__file__)))
try:
    blob_service.put_block_blob_from_path(
            'mycontainer',
            '123.jpg',
            path.join(path.join(PROJECT_ROOT,'uploads'),'123.jpg'),
            x_ms_blob_content_type='image/jpg'
    )
    result = True
except:
    print(sys.exc_info()[1])
    result = False
return HttpResponse(result)


def listfiles(request):
    blob_service = BlobService(account_name=accountName, account_key=accountKey)
    blobs = []
    result = []
    marker = None
    while True:
        batch = blob_service.list_blobs('mycontainer', marker=marker)
        blobs.extend(batch)
        if not batch.next_marker:
            break
        marker = batch.next_marker
    for blob in blobs:
        result.extend([{'name':blob.name}])
    return HttpResponse(json.dumps(result))
