Example Overview

Content Generation
Title
Example Introduction
Returning an HTML Page
Validates the request header and value. Responds if the validation is passed, and rejects if not.
Returning a JSON Object
Generates a JSON object and responds to the client with it.
Access Control
Title
Example Introduction
Authenticating a Request Header
Validates the request header and value. Responds if the validation is passed, and rejects if not.
Protecting Data from Tampering
Calculates the SHA-256 signature of the request body and compares it with the signature generated by the origin server. If they are consistent, it indicates that the content has not been tampered with; otherwise, a 416 status code is returned for response.
Rewriting a m3u8 File and Configuring Authentication
Controls the permissions for .m3u8 and .ts fragment resources.
Custom Referer Rules
Implements custom access control based on the Referer request header.
Remote Authentication
Forwards the request to a specified remote authentication server. Allows access if the validation is passed and denies if not.
HMAC Digital Signature
Uses the Web Crypto API to implement HMAC-SHA256 signature and stores the signature information in the request header, to complete data integrity check or identity authentication in cooperation with the origin server.
Redirect
Title
Example Introduction
Performing Redirect Based on the Request Location
Implements an automatic redirect to the target URL of the client region.
301 Redirect
Implements an automatic and permanent 301 redirect of client requests to the preset website address.
Batch Redirect
Through the predefined redirect mapping table, implements an automatic redirect of specific paths to corresponding URLs.
Obtaining Client Information
Title
Example Introduction
Obtaining Client IP Address
Obtains the client IP address through the rule engine and responds to the client.
Obtaining Client URL Information
Based on the incoming HTTP request, returns the detailed information of the request URL as an HTML page.
Geo Location
Title
Example Introduction
Customization Based on Client Geo Location
Provides customized content based on the country where the client is located.
Obtaining Client Geo Location Information
Responds with the client geo location information, including ASN, country name, country code, region name, region code, city name, longitude, and latitude.
Image Processing
Title
Example Introduction
Adaptive Image Resize
Implements adaptive scaling based on the User-Agent request header.
Image Adaptive WebP
Implements automatic format conversion to WebP based on the Accept request header.
Header Processing
Title
Example Introduction
Modifying a Response Header
Customizes the response headers by adding, modifying, and deleting.
Naming a Downloaded File
Modifies the Content-Disposition information in the response header to change the name of the downloaded file based on the fileName parameter in the request URL.
Cache
Title
Example Introduction
Using the Cache API
Obtains remote resources through the Fetch API and caches resources to EdgeOne edge nodes through the Cache API.
Caching POST Requests
Calculates an SHA-256 signature as the cache key for the POST request body and caches it to an edge node using the Cache API.
Responding in Streaming Mode
Title
Example Introduction
Responding in Streaming Mode
Obtains remote resources and responds to the client in streaming mode.
Merging Resources and Responding in Streaming Mode
Remotely obtains multiple video resources for reading and concatenation in streaming mode, and then responds to the client.
Fetch
Title
Example Introduction
Fetch Remote Resources
Obtains remote resources through the Fetch API and responds to the client.
Cookie
