如何通过CDN加速技术提高Python网站的静态资源访问速度？

import oss2
from aliyunsdkcdn.request.v20180510 import AddCdnDomainRequest
from aliyunsdkcore.client import AcsClient

# 创建OSS存储桶
auth = oss2.Auth('<Your Access-key ID>', '<Your Access-key Secret>')
bucket_name = '<Your bucket name>'
endpoint = '<Your bucket endpoint>'
bucket = oss2.Bucket(auth, endpoint, bucket_name)

# 上传静态资源
local_file = '<Your local static file path>'
bucket.put_object_from_file('<Your remote file path>', local_file)

# 添加CDN域名
client = AcsClient('<Your Access-key ID>', '<Your Access-key Secret>', '<Your region ID>')
request = AddCdnDomainRequest.AddCdnDomainRequest()
request.set_DomainName('<Your CDN domain>')
request.set_Sources('[{"content": "%s"}]' % '<Your remote file path>')
response = client.do_action_with_exception(request)

import falcon
from falcon_cdn import CDNUrlRewrite

# 创建Falcon应用
app = falcon.API(middleware=[CDNUrlRewrite()])

# 创建资源处理器
class StaticResource:
    def on_get(self, req, resp):
        resp.body = 'Hello, World!'
        resp.status = falcon.HTTP_200

# 添加路由
app.add_route('/static', StaticResource())

from flask import Flask, request, send_from_directory

app = Flask(__name__)

# 实现自定义CDN加速
@app.route('/static/<path:filename>', methods=['GET'])
def get_static_file(filename):
    # 获取CDN节点服务器的IP
    cdn_ip = request.headers.get('X-Real-IP')
    
    # 判断请求是否来自CDN节点服务器
    if cdn_ip:
        static_dir = '/path/to/cdn/static/files'
    else:
        static_dir = '/path/to/local/static/files'

    return send_from_directory(static_dir, filename)

if __name__ == '__main__':
    app.run()
