retryhttp

The retryhttp package is HTTP client with configurable retry policy.

Example Use

The retryhttp package is identical to what you would do with net/http. Example:

resp, err := retryhttp.Get("/foo")
if err != nil {
    panic(err)
}

Also was added additional methods Do2Bytes and Do2JSON. Example:

var response struct{
	IP string
}
request, err := http.NewRequestWithContext(ctx, http.MethodGet, "http://ip.jsontest.com", nil)
err = retryhttp.Do2JSON(request, &response)
if err != nil {
    panic(err)
}
	
fmt.Println("You ip", response.IP)

Override retry policy

User can override retry policy for client:

prop := func(properties *Properties) {
    properties.Attempts = 10
    properties.Timeout = time.Second
}
client := New(prop)

Override JSON Unmarshal

User can register choice of JSON library into retryhttp or write own. By default retryhttp registers standard encoding/json respectively.

import "github.com/goccy/go-json"

prop := func(properties *Properties) {
    properties.JSONUnmarshal = json.Unmarshal
}
client := New(prop)
