Django admin实现图片上传到腾讯云
作者:互联网
官网参考:https://docs.djangoproject.com/zh-hans/3.2/howto/custom-file-storage/
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
