Context

Using Go context with SP client
Gosip client respects native Go Context, you can pass a context on a low level or to a Fluent API to control requests's deadlines, cancellation signals, and other request-scoped values across API boundaries and between processes. 
Low level client
On the low level dealing with the contexts is identical to native approach:
client := &gosip.SPClient{AuthCnfg: auth}
​
var req *http.Request
// Initiate API request
// ...
​
req = req.WithContext(context.Background()) // <- pass a context
​
resp, err := client.Execute(req)
if err != nil {
  fmt.Printf("Unable to request api: %v", err)
  return
}
HTTP Client
While using HTTPClient, context is defined together with request config.
spClient := api.NewHTTPClient(&gosip.SPClient{AuthCnfg: auth})
​
endpoint := auth.GetSiteURL() + "/_api/web?$select=Title"
​
reqConf := &api.RequestConfig{
  Context: context.Background(), // <- pass a context
}
​
data, err := spClient.Get(endpoint, reqConf)
if err != nil {
  log.Fatalf("%v\n", err)
}
​
// spClient.Post(endpoint, body, reqConf) // generic POST
​
// generic DELETE helper crafts "X-Http-Method"="DELETE" header
// spClient.Delete(endpoint, reqConf)
​
// generic UPDATE helper crafts "X-Http-Method"="MERGE" header
// spClient.Update(endpoint, body, reqConf)
​
// CSOM helper (client.svc/ProcessQuery)
// spClient.ProcessQuery(endpoint, body, reqConf)
Fluent API
With Fluent API, context is managed in the same way as in the previous example with the only difference how it is chained to fluent syntax.
config := &api.RequestConfig{
  Context: context.Background(), // <- pass a context
}
​
sp := api.NewSP(client).Conf(config)
​
data, err := sp.Web().Lists().Select("Id,Title").Get()
if err != nil {
	log.Fatalln(err)
}
Conf method can be used almost on any hierarchy level. It's inherited with capability to redefine.
