在Django中加載圖像時的SuspiciousOperation

Question

我正在django中部署Web應用程序，並且有一個頁面從我的靜態文件中加載了一些圖像，該頁面返回以下錯誤：

SuspiciousOperation at /wallet
Attempted access to '/coins/' denied.

我一直在讀，這是因為媒體文件，但是我不明白，因為所有其他靜態文件都正確加載。 我正在使用AWS的s3。

這是我的s3配置文件：

import datetime
import os
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
AWS_ACCESS_KEY_ID = "whatever"
AWS_SECRET_ACCESS_KEY = "whatever"
AWS_STORAGE_BUCKET_NAME = 'xxx'
AWS_S3_CUSTOM_DOMAIN = '%s.s3.us-east-2.amazonaws.com' % AWS_STORAGE_BUCKET_NAME
AWS_S3_OBJECT_PARAMETERS = {
    'CacheControl': 'max-age=86400',
}
AWS_LOCATION = 'static'

STATICFILES_DIRS = [
    os.path.join(BASE_DIR, '../static'),
]
STATIC_URL = 'https://%s/%s/' % (AWS_S3_CUSTOM_DOMAIN, AWS_LOCATION)
STATICFILES_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage'
MEDIA_URL = ''
MEDIA_ROOT = ''

調試模式下的整個錯誤如下：

非常感謝。

Django根據MEDIA_URL自動為媒體文件創建路徑，即/ media /

字段中的值不是以“ /”開頭，並且django認為它是可疑的值/操作，因為如果存在某些技巧，您/黑客應該可以使用系統文件。

嘗試通過Django shell或sql查詢將字段值從'/coins/abc.jpg' 'coins/abc.jpg'手動更改為'coins/abc.jpg' 。

Django默認情況下在后一種模式中創建值
