访问设置
设置访问凭据时，有两个选项：
选项1：
生成访问凭据并将其直接添加到django设置中。 如果使用amazon s3，您还需要创建一个iam策略，该策略授予 允许将新创建的凭据上载到您的存储桶。 记住用your_bucket_name替换实际的bucket。
{"Version":"2012-10-17","Statement":[{"Effect":"Allow","Action":["s3:GetObject","s3:PutObject","s3:PutObjectAcl","s3:ListMultipartUploadParts","s3:AbortMultipartUpload"],"Resource":"arn:aws:s3:::YOUR_BUCKET_NAME/*"}]}
选项2：
使用ec2实例配置文件及其附加的iam角色（仅限aws）
您需要确保除了

CORS设置
你需要在你的水桶上加上一个cors保险单。注意etag头是 重要，因为它用于多部分上传。有关更多信息，请参见 here。 记住在下面的示例中交换掉yourdomain.com，包括port if 在当地发展。
如果使用数字海洋空间，则必须通过api/s3cmd上传cors配置
cli（因为您不能添加ExposeHeader规则）。见

urlpatterns=[...url(r'^s3direct/',include('s3direct.urls')),...]
如果需要，请运行python manage.py collectstatic。
在django admin中使用
型号.py
fromdjango.dbimportmodelsfroms3direct.fieldsimportS3DirectFieldclassExample(models.Model):video=S3DirectField(dest='example_destination')
以自定义形式使用小部件
表格.py
fromdjangoimportformsfroms3direct.widgetsimportS3DirectWidgetclassS3DirectUploadForm(forms.Form):images=forms.URLField(widget=S3DirectWidget(dest='example_destination'))
*可选。您可以通过覆盖模板s3direct/templates/s3direct widget.tpl修改小部件的HTML
