Header request Injector 作成者: JedGBC

The extension allows the user to define rules for modifying HTTP/HTTPS headers (adding, editing, or removing headers) that are automatically applied to network requests matching user-configured URL filters, while displaying the currently active rules in the popup.

Built for developers who need to simulate API clients, test gateway rules, or validate backend behavior with specific headers.

Key features:

• URL filter matching with AND / OR logic
• Optional URL exclude rules
• Custom request headers per configuration
• Global ON/OFF toggle
• Recent match log (method, URL, timestamp, injected headers)
• DevTools helper for quick inspection, commands on console:
• HeaderInjector()
• HeaderInjector('config')
• HeaderInjector('log')
• HeaderInjector.clear / HeaderInjector('log').clear / HeaderInjector('config').clear
• Local storage only (no remote sync or external servers)

How it works:

• You configure filters and headers in the popup
• The extension applies rules in the browser
• Matching requests are logged for debugging

Privacy:

• Data is stored locally in your browser storage
• No analytics, no telemetry, no external data collection

Intended use:

• Development, QA, staging, and local debugging environments
