import ( "net/http" "github.com/go-openapi/runtime" ) func main() { client := http.Client{} request := runtime.ClientRequest{} request.SetQueryParam("key", "value") response, err := client.Do(&request) // Handle response and error }In the above code, the runtime.ClientRequest struct is utilized to set the query parameter "key" with the value "value" using the SetQueryParam method. The resulting HTTP request is then sent using an HTTP client. Overall, the go github.com.go-openapi.runtime package is a helpful tool for developers who need to send HTTP requests with query parameters.
