I'm following a tutorial on integrating a Go backend with Flutter from this YouTube video. Despite following the instructions closely, I'm unable to retrieve data from the backend into my Flutter application. The tutorial's author suggested printing the HTTP status code using response.statusCode to debug, but I'm unsure how to implement this in Go.
Context:
I'm relatively new to Go and working on a project that involves setting up a backend service for a Flutter app. The goal is to send and receive data between the Flutter frontend and the Go backend. While testing, I encountered issues with data retrieval and was advised to check the HTTP status code to diagnose the problem.
Code:
package main
import (
"encoding/json"
"fmt"
"log"
"net/http"
"github.com/gorilla/mux"
)
type Tasks struct {
ID string `json:"id"`
TaskName string `json:"task_name"`
TaskDetail string `json:"detail"`
Date string `json:"date"`
}
var tasks []Tasks
func allTasks() {
// Code for initializing tasks omitted for brevity
}
func homePage(w http.ResponseWriter, r *http.Request) {
fmt.Println("I am home page")
}
func getTasks(w http.ResponseWriter, r *http.Request) {
w.Header().Set("Content-Type", "application/json")
json.NewEncoder(w).Encode(tasks)
}
// Other handlers omitted for brevity
func handleRoutes() {
router := mux.NewRouter()
// Routes setup omitted for brevity
log.Fatal(http.ListenAndServe(":3306", router))
}
func main() {
allTasks()
handleRoutes()
}
What I've Tried:
- I verified that the routes are correctly set up and that the server is running without errors.
- I attempted to log the output in the Flutter app to check if the data is received but found no useful information.
Question:
How can I modify my Go code to print the HTTP status code when making requests? I believe understanding how to log these status codes correctly will help me debug the connectivity issue with my Flutter front end.
