How to improve the static resource access speed of Python website through CDN acceleration technology?

With the development of the Internet, the demand for website access speed is getting higher and higher, especially for access to static resources. In order to improve user experience and website performance, using CDN (content delivery network) acceleration technology has become a common choice. This article will introduce how to improve the static resource access speed of Python websites through CDN acceleration technology, and provide you with specific code examples.

CDN is a distributed network architecture that improves resource access speed by storing static resources of the website (such as images, CSS and JavaScript files, etc.) on node servers closer to the user. and response time. The following are some Python-based CDN acceleration technology practices.

1. Use the CDN of a cloud service provider: Cloud service providers such as Alibaba Cloud, Tencent Cloud and Qiniu Cloud all provide powerful CDN services. You can upload your static resources to a cloud storage bucket, and then configure a CDN acceleration domain name to achieve acceleration. The following is a code example using Alibaba Cloud CDN:

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)

2. Using Python's CDN acceleration library: In addition to using the cloud service provider's CDN, you can also use Python's CDN acceleration library to achieve this. CDN acceleration. For example, we can use the Falcon library to provide web services and use the CDNUrlRewrite middleware to implement CDN acceleration. The following is a code example using the Falcon library:

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())

3. Use a custom CDN acceleration method: If you want to control the CDN acceleration process more flexibly, you can customize the CDN acceleration method. The following is a code example for implementing custom CDN acceleration through Nginx and Python's Flask framework:

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()

Through the above method, you can easily use CDN acceleration technology to improve static resource access on Python websites speed. No matter which method you choose to use, you'll get a better user experience and faster website responsiveness for your users. Hope this article helps you!
