golang parses HAR files

What is Har?

https://w3c.github.io/web-performance/specs/HAR/Overview.html

Feature

  • supports standard HAR-1.2 content parsing
  • replay HTTP request based on har content stub content
  • supports HTTP synchronous requests and asynchronous concurrent requests
  • file import and export
  • can be embedded in HTTP services to present data
  • other conversion help functions, etc

Use restriction

  • golang version >= 1.9
