What is Charles Proxy?
Charles is an HTTP proxy, HTTP monitor, and web debugging proxy application. It sits between a machine and the Internet as a forward proxy, letting developers view all HTTP and SSL/HTTPS traffic passing through. This includes requests, responses, and HTTP headers containing cookies and caching information.
Why use it in the API Lifecycle?
- Traffic Recording: Records all HTTP and HTTPS traffic between the machine and the Internet.
- Content Inspection: Displays the contents of HTTP requests, responses, cookies, and headers.
- SSL/HTTPS Support: Functions as an SSL/HTTPS proxy to inspect encrypted traffic.
- Network Throttling: Allows simulation of slower internet connection speeds for testing.
- Traffic Statistics: Provides statistics for network activity.
Best Practices
- Utilize Charles for observing and modifying traffic during mobile application testing workflows.
- Employ Charles to debug HTTP connections specifically for mobile devices.
- Analyze application store XML data by proxying traffic through Charles.
- Debug Flash/server interactions by monitoring traffic flows in Charles.
