What protocols did you use to obtain data in your last project?

In my last project in Go for data retrieval, I used the following protocols:

• HTTP/HTTPS — the main protocol for interacting with REST API. Used the standard net/http package for sending requests and receiving responses.

• gRPC — a remote procedure call protocol supporting HTTP/2, which allows efficient data exchange between services. Used for internal microservice communication.

• WebSocket — for real-time data reception, for example, to update the UI when data on the server changes.

Example of a simple HTTP GET request in Go:

resp, err := http.Get("https://api.example.com/data")
if err != nil {
    log.Fatal(err)
}
defer resp.Body.Close()
body, err := ioutil.ReadAll(resp.Body)
if err != nil {
    log.Fatal(err)
}
fmt.Println(string(body))

The choice of protocol depends on performance requirements, reliability, and the nature of the data.
