import ( "encoding/json" "fmt" "github.com/rackspace/gophercloud" ) func main() { // create a new ServiceClient endpoint := "https://api.com/some/endpoint" client, err := gophercloud.NewServiceClient(endpoint) if err != nil { panic(err) } // create a payload to send data := map[string]string{ "name": "John Doe", "age": "30", } payload, err := json.Marshal(data) if err != nil { panic(err) } // make a POST request to the endpoint resp, err := client.Post(endpoint, payload) if err != nil { panic(err) } defer resp.Body.Close() // print the response body body, err := ioutil.ReadAll(resp.Body) if err != nil { panic(err) } fmt.Println(string(body)) }In this example, we create a new ServiceClient by specifying the endpoint URL. We then create a JSON payload to send and use the Post method to make a POST request to the endpoint. Finally, we print the response body.
