当前业务需要使用django的admin后台进行数据的管理,需要实现文件的上传云端-腾讯云
具体实现:
安装依赖包:pip install cos-python-sdk-v5==1.9.10
自定义一个存储类:
1)继承Django.core.files.storage.Storage
2)重写save方法
3)添加装饰器,方便进行数据库文件的迁移django.utils.deconstruct.deconstructible
demo:
#!/usr/bin/env python# -*- coding: utf-8 -*-
from django.conf import settings
from django.core.files.storage import Storage
from django.utils.deconstruct import deconstructible
from qcloud_cos import CosConfig, CosS3Client
from .common import generate_img_url
secret_id = settings.OSS_QCLOUD_SECRET_ID
secret_key = settings.OSS_QCLOUD_SECRET_KEY
region = settings.OSS_QCLOUD_REGION
bucket = settings.OSS_QCLOUD_BUCKET
token = settings.OSS_QCLOUD_TOKEN
scheme = settings.OSS_QCLOUD_SCEHME
config = CosConfig(Region=region, SecretId=secret_id, SecretKey=secret_key, Token=token, Scheme=scheme)
client = CosS3Client(config)
host = settings.OSS_PREFIX
@deconstructible
class CosStorage(Storage):
def save(self, name, content, max_length=None):
"""
重写save方法
"""
# suffix = name.split('.')[-1]
# key = self.generate_key(suffix)
key = generate_img_url(name)
try:
response = client.put_object(
Bucket=bucket,
Body=content.read(),
Key=key,
StorageClass='STANDARD',
EnableMD5=True
)
except Exception as e:
raise
return host + key
def url(self, name):
return name
配置文件中需要添加配置项:
OSS_QCLOUD_SECRET_ID = 'sercret-id'OSS_QCLOUD_SECRET_KEY = 'secret-key'
OSS_QCLOUD_REGION = '所选区域'
OSS_QCLOUD_BUCKET = '创建的bucket'
OSS_QCLOUD_TOKEN = None
OSS_QCLOUD_SCEHME = 'https'
OSS_NAMESPACE = '可以区分场景'
OSS_PREFIX = 'https://xxx.cos.所选区域.myqcloud.com'
公共方法:
# 生成图片路径def generate_img_url(file_name, scene='default'):
file_ext = file_name.rsplit('.', 1)[-1]
new_file_name = scene + '_' + str(datetime.datetime.today()).replace('-', '').replace(' ', '_').replace(':', '') + '.' + file_ext
namespace = settings.OSS_NAMESPACE
return f'/{namespace}/' + new_file_name
最后添加到model中定义的字段中
file = models.FileField(verbose_name='文件', storage=CosStorage())# 注意:这里使用的FileField 如果是图片的话可以使用ImageField
