Some Common API examples

Create Client
    client, err := minio.NewV2(Url, AccessKey, SecretKey, true)
    if err != nil {
    	log.Fatalln(err)
    }
	
Create Bucket	and List buckets
    err = client.MakeBucket("bucketName", "")
    if err != nil {
    	log.Fatalln(err)
    }
    buckets, err := client.ListBuckets()
    if err != nil {
    	log.Fatalln(err)
    }
    for _, bucket := range buckets {
    	log.Println(bucket)
    }
List Objects and Delete All Objects In Bucket
    doneCh := make(chan struct{})
    defer close(doneCh)
    var objectNames []string
    for object := range s3Client.ListObjects(MyBucket, "", true, doneCh) {
  		if object.Err != nil {
  			fmt.Println(object.Err)
  			return
  		}
  		objectNames = append(objectNames, object.Key)
  	}
  	var wg sync.WaitGroup
  	for _, name := range objectNames {
  		wg.Add(1)
  		go func(name string) {
  			defer wg.Done()
  			err = s3Client.RemoveObject(MyBucket, name)
  			if err != nil {
  				log.Fatalln(err)
  			}
  			log.Println("Success", name)
  		} (name)
  	}
  	wg.Wait()
GetObject
    reader, err := client.GetObject(MyBucket, MyObject)
  	if err != nil {
  		log.Fatalln(err)
  	}
  	defer reader.Close()
  
  
  	localFile, err := os.Create("/Users/raunak.agarwal/Desktop/text3.txt")
  	if err != nil {
  		log.Fatalln(err)
  	}
  	defer localFile.Close()
  
  	stat, err := reader.Stat()
  	if err != nil {
  		log.Fatalln(err)
  	}
  
  	if _, err := io.CopyN(localFile, reader, stat.Size); err != nil {
  		log.Fatalln(err)
  	}
