Fiber Client

Easy-to-use HTTP client based on fasthttp (inspired by resty and axios)

Features section describes in detail about Resty capabilities

Features

The characteristics have not yet been written.

  • GET, POST, PUT, DELETE, HEAD, PATCH, OPTIONS, etc.
  • Simple and chainable methods for settings and request
  • Request Body can be string, []byte, map, slice
    • Auto detects Content-Type
    • Buffer processing for files
    • Native *fasthttp.Request instance can be accessed during middleware and request execution via Request.RawRequest
    • Request Body can be read multiple time via Request.RawRequest.GetBody()
  • Response object gives you more possibility
    • Access as []byte by response.Body() or access as string by response.String()
  • Automatic marshal and unmarshal for JSON and XML content type
    • Default is JSON, if you supply struct/map without header Content-Type
    • For auto-unmarshal, refer to -
      • Success scenario Request.SetResult() and Response.Result().
      • Error scenario Request.SetError() and Response.Error().
      • Supports RFC7807 - application/problem+json & application/problem+xml
    • Provide an option to override JSON Marshal/Unmarshal and XML Marshal/Unmarshal

Usage

The following samples will assist you to become as comfortable as possible with Fiber Client library.

// Import Fiber Client into your code and refer it as `client`.
