對于小型站點，使用七牛云存儲的免費配額已足夠為站點提供穩定、快速的存儲服務
七牛云存儲已有Python SDK，對它進行簡單封裝后，就可以直接在Flask中使用了，項目代碼見GitHub上Flask-QiniuStorage。
使用示例代碼：
復制代碼代碼如下:
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 = '七牛空間名稱'
QINIU_BUCKET_DOMAIN = '七牛空間對應域名'
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)
# 刪除七牛空間中的文件
@app.route('/delete')
def delete():
filename = 'filename'
ret, info = qiniu_store.delete(filename)
return str(ret)
# 根據文件名獲取對應的公開URL
@app.route('/url')
def url():
filename = 'filename'
return qiniu_store.url(filename)
