A cached http client for the KrakenD framework
This package exposes two simple factories capable to create a instances of the proxy.HTTPClientFactory and the proxy.BackendFactory interfaces, respectively, embedding an in-memory-cached http client using the package github.com/gregjones/httpcache. The client will cache the responses honoring the defined Cache HTTP header.
import (
"context"
"net/http"
"github.com/luraproject/lura/v2/config"
"github.com/luraproject/lura/v2/proxy"
"github.com/luraproject/lura/v2/transport/http/client"
"github.com/krakendio/krakend-httpcache/v2"
)
requestExecutorFactory := func(cfg *config.Backend) proxy.HTTPRequestExecutor {
clientFactory := httpcache.NewHTTPClient(cfg, client.NewHTTPClient)
return func(ctx context.Context, req *http.Request) (*http.Response, error) {
return clientFactory(ctx).Do(req.WithContext(ctx))
}
}
You can create your own proxy.HTTPRequestExecutor and inject it into your BackendFactory
