http retry round tripper library

[mmat...@gmail.com]

Can someone recommend a http retry round tripper library? 

I searched multiple projects none is doing what I want.

The closest is https://github.com/hashicorp/go-retryablehttp but it's a full client, I'm tempted to port it to http.RoundTripper.

Thanks

Does this meet your needs?

https://github.com/One-com/gone/tree/master/http/vtransport

The docs could be better, I admit.

it's shouldn't be difficult to adapt it to an http.RoundTripper yourself

potentially there are some details/considerations missing in this implementation tho?

type Adapter struct {

retryable *retryablehttp.Client

}

func (a Adapter) RoundTrip(r *http.Request) (*http.Response, error) {

var body io.ReadSeeker

if r.Body != nil {

defer r.Body.Close()

b, err := ioutil.ReadAll(r.Body)

if err != nil {

return nil, err

}

body = bytes.NewReader(b)

}

req, err := retryablehttp.NewRequest(r.Method, r.URL.String(), body)

if err != nil {

return nil, err

}

req.Header = r.Header

return a.retryable.Do(req)

}

you could also copy the body w/ `io.Copy`
