对于小型站点,使用七牛云存储的免费配额已足够为站点提供稳定、快速的存储服务
七牛云存储已有Python SDK,对它进行简单封装后,就可以直接在Flask中使用了,项目代码见GitHub上Flask-QiniuStorage。
使用示例代码:
from flask import Flask from flask_qiniustorage import Qiniu QINIU_ACCESS_KEY = '七牛 Access Key' QINIU_SECRET_KEY = '七牛 Secret Key' QINIU_BUCKET_NAME = '七牛空间名称' QINIU_BUCKET_DOMAIN = '七牛空间对应域名' app = Flask(__name__) app.config.from_object(__name__) qiniu_store = Qiniu(app) # 或者 # qiniu_store = Qiniu() # qiniu_store.init_app(app) # 保存文件到七牛 @app.route('/save') def save(): data = 'data to save' filename = 'filename' ret, info = qiniu_store.save(data, filename) return str(ret) # 删除七牛空间中的文件 @app.route('/delete') def delete(): filename = 'filename' ret, info = qiniu_store.delete(filename) return str(ret) # 根据文件名获取对应的公开URL @app.route('/url') def url(): filename = 'filename' return qiniu_store.url(filename)
