network_interception

Go SDK Network Interception Example

This is a single, minimal example of callback-based response interception with the Go SDK.

It shows one after hook callback that:

• runs only for host=httpbin.org and path=/response-headers
• removes response header X-Upstream
• adds response header X-Intercepted: callback
• fully replaces the response body with {"msg":"from-callback"}

Run

From the repository root:

go run ./examples/go/network_interception

The example uses matchlock from PATH by default. If you want to override the binary path, set:

export MATCHLOCK_BIN=/path/to/matchlock

What To Expect

The command output should include:

• response body {"msg":"from-callback"}
• header X-Intercepted: callback
• final line: OK: callback hook intercepted and mutated the response

The program exits with an error if those expectations are not met.
