func main() {

router := mux.NewRouter()

router.HandleFunc("/", handlePostFile)

log.Fatal(http.ListenAndServe(":8080", router))

}

func handlePostFile(w http.ResponseWriter, r http.Request) {

// Parse multipart form and store files to disk

if err := r.ParseMultipartForm(32 << 20); err != nil {

http.Error(w, "Cannot parse multipart form", http.StatusBadRequest)

return

}

file, handler, err := r.FormFile(r.PostFormValue("filename"))

if err != nil {

http.Error(w, "Cannot retrieve file", http.StatusBadRequest)

return

}

f, err := os.OpenFile("./uploads/"+handler.Filename, os.O_WRONLY|os.O_CREATE, 0666)

if err != nil {

http.Error(w, "Cannot save file", http.StatusInternalServerError)

return

}

defer f.Close()

if _, err = io.Copy(f, file); err != nil {

http.Error(w, "Cannot copy file to disk", http.StatusInternalServerError)

return

}

fmt.Fprintf(w, "File %q uploaded successfully", handler.Filename)

}

func main() {

ctx := context.Background()

// Replace "your-bucket-name" with the name of your bucket

bucketName := "your-bucket-name"

// Initialize client

client, err := cloudstorage.NewClient(ctx)

if err != nil {

fmt.Println(err)

return

}

// Upload file

f := client.Bucket(bucketName).Object("my-file.txt")

wr := f.NewWriter(ctx)

if _, err := wr.Write([]byte("Hello, world!")); err != nil {

fmt.Println(err)

return

}

if err := wr.Close(); err != nil {

fmt.Println(err)

return

}

fmt.Printf("File uploaded to %s", f.GCSObject.MediaLink)

}
