rester

Library for simple REST calls GET, POST, PUT, DELETE without worrying about nitty gritties. You could chose to make the calls with periodic retry, exponential backoff, or just once.

Install

go get github.com/govindamurali/rester

Usage

Initialize request and response structs

  type Request struct{
    SomeReqData string `json:"some_req_data"`
  }
  
  type Response struct{
    SomeRespData string `json:"some_resp_data"`
  }

Initialize request and response variables

  request:= Request{SomeReqData: "some value"}
  response:= Response{}	

Initialize request methods

  postRequest := rester.PostRequest(url, request, &response, customHeaders, customTransport)
  getRequest := rester.GetRequest(url, &response, nil, nil)    
  putRequest :=  rester.PutRequest(url, request, &response, nil, nil)   
  deleteRequest := rester.DeleteRequest(url, request, &response, customHeaders, customTransport)

Make the call

  httpResponse,err := postRequest.Once()
  httpResponse,err := getRequest.WithConstantRetry(maxTimeOutInSeconds)
  httpResponse,err := putRequest.WithExponentialRetry(maxTimeOutInSeconds)

Miscellaneous

• You'll be able to get the response in the response variable & httpStatus in httpResponse variable
• customHeaders are optional. Will use defaultHeaders when nil
• customTransport is optional. Will use defaultTransport when nil. Tip - Use newrelic agent transport to get metrics tracked on newrelic.
