You can greatly simplify your code by using a proper struct for your JSON unmarshaling: type Request struct { URL string `json:”url”` Params map[string]interface{} `json:”params”` Type string `json:”type”` } Then you can unmarshal it more simply as so: request := &Request{} if err := json.Unmarshal([]byte(j), &request); err != nil { panic(err) } And access the … Read more
Here is an example with marshal and unmarshal using your object definition package main import ( “encoding/json” “fmt” ) type MyObject struct { ID string `json:”id”` Name string `json:”name”` Planets map[string]int `json:”planets”` } func main() { aa := &MyObject{ ID: “123”, Name: “pepe”, Planets: map[string]int{ “EARTH”: 3, “MARS”: 4, }, } // Marshal out, err … Read more
tick is a channel in Go. If you look at the docs, tick should send something to the channel once each time interval, which is specified by time.Duration(1000/config.Samplerate) * time.Millisecond in your code. <-tick just waits for that time interval to pass. i keeps track of how many seconds pass, so every time it ticks, … Read more

The answer which I was looking is how to get the country code by passing the phone number only, this is the solution which is working perfectly. num, err := phonenumbers.Parse(“+123456789”, “”) if err != nil { fmt.Println(err.Error()) } regionNumber := phonenumbers.GetRegionCodeForNumber(num) countryCode := phonenumbers.GetCountryCodeForRegion(regionNumber) fmt.Println(countryCode) Thank you Yacacov for the hint 😉 solved Golang … Read more
You have to declare your channel variable outside the loop if you want to re-use it in each iteration (errors and context omitted for brevity): package main import “fmt” func main() { var pipeline Pipeline pipeline.Steps = append(pipeline.Steps, AddBang{}, AddBang{}, AddBang{}, ) src := make(chan Message) pipe := src for _, s := range pipeline.Steps … Read more

From the below information provided by you: when I iterate over it and return the values they return [hello] [world] It seems that your currentMap actually stores string slices []string as values, behind the interface{} type. Assuming that above line means that you see this when printing the map using fmt.Println(), or similar functions. map[first:[hello] … Read more
