HomeBackend DevelopmentPython TutorialPython Web框架Flask中使用百度云存储BCS实例

对于部署在百度应用引擎BAE上的项目,使用百度云存储BCS(Baidu Cloud Storage)是不错的存储方案。

百度云存储已有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-BCS。

使用示例代码:

代码如下:


from flask import Flask
from flask_bcs import BCS
 
BCS_HOST = 'BCS HOST'
BCS_ACCESS_KEY = 'BCS Access Key'
BCS_SECRET_KEY = 'BCS Secret Key'
BCS_BUCKET_NAME = 'BCS Bucket Name'
 
app = Flask(__name__)
app.config.from_object(__name__)
bcs = BCS(app)
# 或者
# bcs = BCS()
# bcs.init_app(app)
 
# 保存文件到BCS
@app.route('/save')
def save():
    data = 'data to save'
    filename = 'filename'
    allow_referers = ['http://*.duapp.com/*', 'http://zhangxc.com/*']
    # 不设置allow_referers为完全public
    ret = bcs.save(data, filename, allow_referers)
    return str(ret)
 
# 删除BCS中的文件
@app.route('/delete')
def delete():
    filename = 'filename'
    ret = bcs.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 bcs.url(filename)

In Python 3, two lists can be connected through a variety of methods: 1) Use operator, which is suitable for small lists, but is inefficient for large lists; 2) Use extend method, which is suitable for large lists, with high memory efficiency, but will modify the original list; 3) Use * operator, which is suitable for merging multiple lists, without modifying the original list; 4) Use itertools.chain, which is suitable for large data sets, with high memory efficiency.

Using the join() method is the most efficient way to connect strings from lists in Python. 1) Use the join() method to be efficient and easy to read. 2) The cycle uses operators inefficiently for large lists. 3) The combination of list comprehension and join() is suitable for scenarios that require conversion. 4) The reduce() method is suitable for other types of reductions, but is inefficient for string concatenation. The complete sentence ends.

Python is an interpreted language, but it also includes the compilation process. 1) Python code is first compiled into bytecode. 2) Bytecode is interpreted and executed by Python virtual machine. 3) This hybrid mechanism makes Python both flexible and efficient, but not as fast as a fully compiled language.
