import ( "github.com/go-swagger/go-swagger/client" ) func main() { // Create a new client swaggerClient := client.NewHTTPClient("http://example.com", "v1") // Create a new request req := swaggerClient.MyAPI.MyOperation() // Set a query parameter on the request req.SetQueryParam("param1", "value1") // Send the request and handle the response resp, err := req.Execute() // Handle the response or error if err != nil { // Handle the error } else { // Handle the response } }In this example, we are creating a new client using the `client.NewHTTPClient` method and setting the base URL to `"http://example.com"` and API version to `"v1"`. We then create a new request for the `MyOperation` endpoint on the API using `swaggerClient.MyAPI.MyOperation()`. We set a query parameter on the request using the `req.SetQueryParam()` method, passing in the parameter name and value. Finally, we execute the request using `req.Execute()` and handle the response or error. The `SetQueryParam` method is part of the `client.HTTPRequest` struct which is defined in the `github.com/go-swagger/go-swagger/client` package.
