Question

我正在尝试使用boto3创建预先签名的帖子签名和表单。

 key = str(venuepk) +'/' + str(samplemenuid) + '/${filename}'
            fields = {'acl': 'public-read',
                      'content-type': 'application/PDF'}
            conditions = {'acl': 'public-read',
                      'content-type': 'application/PDF'}
            s3=boto3.client('s3')
            post = s3.generate_presigned_post(
                Bucket = AWS_UPLOAD_BUCKET,
                Key = key,
                Fields = fields,
                Conditions=conditions
            )
            return Response({
                'url': post['url'],
                'fields': post['fields'],
                'samplemenupk': samplemenuid
            })

跟随文档到'T'

https://boto3.readthedocs.io/en/latest/guide/s3.html#generating-presigned-posts

但我一直收到这个错误：

    response = handler(request, *args, **kwargs)

    conditions.append({'bucket': bucket})
AttributeError: 'dict' object has no attribute 'append'

Answer 1

错误是因为python dicts没有附加方法。条件值应该是一个列表，如下所示

conditions = [
    {"acl": "public-read"},
    ["content-length-range", 10, 100]
]

它实际上显示为documentation

中的列表

AttributeError：'dict'对象没有属性'append'boto3生成预签名帖子
