Request Inspection

Similar to using curl -v, it can often be useful to inspect the raw request and response when debugging or understanding the behavior of a server.

the httpr.Inspect option can be used to log the request and response to stdout. This option can be set globally when creating a client or per request

Global

httpc := httpr.NewClient(
  httpr.Inspect(),
)

resp, err := httpc.Get(context.Background(), "https://jsonplaceholder.typicode.com/posts/1")

Per Request

httpc := httpr.NewClient()

resp, err := httpc.Get(context.Background(), "https://jsonplaceholder.typicode.com/posts/1",
  httpr.Inspect(),
)

Output

inspecting a GET request to https://jsonplaceholder.typicode.com/posts/1 will produce the following output:
