Usage

single task

func TestSingle(t *testing.T) {
    task := gex.NewTask("https://wx2.sinaimg.cn/large/008h3uCply1gtumw52q7aj31nj27enk8.jpg")
    task.SetTimeout(time.Second * 10)
    err := task.Do(context.TODO())
    if err == nil {
        println(humanize.IBytes(uint64(task.Result().Transfer())))
        println(task.Result().Transfer())
    }
}

batch tasks

func TestMany(t *testing.T) {
    t1 := gex.NewTask("https://wx2.sinaimg.cn/large/008h3uCply1gtumw52q7aj31nj27enk8.jpg")
    t2 := gex.NewTask("https://wx1.sinaimg.cn/large/002MwiQagy1gwmv16ypycj60dcatwe8102.jpg")
    
    var bat gex.Batch
    
    bat.Add(t1, t2)
    bat.Run()
    
    t.Log(t1.Result())
    t.Log(t2.Result().Err)
    t.Log(t2.Result().Time())
}
