Howdy there!!!
Usually when we want to integrate with cache (let's say Redis), we usually have to do many changes in our code. What if, we just inject the cache to the HTTP client. So we don't have to create many changes in every line of our code to support the cache features? With only less than 10 line of code, you can got a complete implementations of HTTP Cache based on RFC 7234
This package is used for caching your http request results from the server. Example how to use can be seen below.
You can file an Issue. See documentation in Godoc
go get -u github.com/bxcodec/httpcacheExample how to use more details can be seen in the sample folder: /sample
Short example:
// Inject the HTTP Client with httpcache
client := &http.Client{}
_, err := httpcache.NewWithInmemoryCache(client, time.Second*60)
if err != nil {
log.Fatal(err)
}
// And your HTTP Client already supported for HTTP Cache
// To verify you can run a request in a loop
for i:=0; i< 10; i++ {
startTime := time.Now()
req, err := http.NewRequest("GET", "https://bxcodec.io", nil)
if err != nil {
log.Fatal((err))
}
res, err := client.Do(req)
if err != nil {
log.Fatal(err)
}
fmt.Printf("Response time: %vms\n", time.Since(startTime).Microseconds())
fmt.Println("Status Code", res.StatusCode)
}
// See the response time, it will different on each request and will go smaller.- See the issues
- pquerna/cachecontrol for the Cache-Header Extraction
- bxcodec/gothca for in-memory cache. *Notes: if you find another library that has a better way for inmemm cache, please raise an issue or submit a PR
