search

Search serves as a proxy for Google search, and contains the following uniform interfaces in the package.go file:

// Resource identifier
const (
    PkgPath = "github/advanced-go/search/provider"
)

// HttpHandler - HTTP handler endpoint
func HttpHandler(w http.ResponseWriter, r *http.Request) {
    // implementation details	
}

Search also utilizes a resolver for building URI's.

func init() {
  resolver.SetTemplates([]uri2.Pair{{searchPath, "https://www.google.com/search?%v"}})
}

// Perform resolution through expansion
uri := resolver.Build(searchPath, values.Encode())

A controller is configured and used for implementing timeouts and access logging. Access logging is provided by a uniform interface in core/access.

func init() {
	buf, err := fs.ReadFile(f, controllersPath)
	cm, err = controller.NewMap(buf)
}

// Controller apply call 
defer apply(ctx, &newCtx, access.NewRequest(h, http.MethodGet, uri), &resp, googleControllerName, access.StatusCode(&status))()
