Hi ,
You are right but am new to programming and currently this what i have done.
I have an http server handler that receives the PATCH request and stores
the id and the current time stamp of the request.
But my problem is how to write the worker function to do the clean up every
X seconds.
Code:
func UpdateData(response http.ResponseWriter, request *http.Request) {
var (
localVarHTTPMethod = http.MethodPatch
patchItems model.PatchItem
)
id := config.GetIdFromRequest(request)
if request.Method == localVarHTTPMethod {
err := json.NewDecoder(request.Body).Decode(&patchItems)
if err != nil {
common.WriteError(response, common.ErrBadRequest)
return
}
defer request.Body.Close()
var idtime = make(map[string]string)
delete(idtime, id) // delete if already exist
idtime[id] = time.Now() // store id and time stamp in map
// how do i write a worker to the clean up after every X seconds?
} else {
common.WriteError(response, common.ErrMethodNotAllowed)
return
}
}
