amazon-web-services - HITLayoutParameters如何填写

Question

这是我通过Go向mturk发送请求的方式:

resp_create, err := svc.CreateHIT(&mturk.CreateHITInput{
    Title: aws.String("Title Sample"),
    Reward:   aws.String("1"),
    Description:  aws.String("Sample Desc"),
    HITLayoutId: aws.String("33XXXXXXXXXXXX"),
    HITLayoutParameters: []mturk.HITLayoutParameter{"image_url", "https://nationalinterest.org/sites/default/files/styles/desktop__1260_/public/main_images/fdgtrtttr.jpg?itok=RnfT8ENG"},
    AssignmentDurationInSeconds: aws.Int64(604800),
    LifetimeInSeconds: aws.Int64(604800),
    Keywords:aws.String("image, identification"),
}) 

哪些由于某种原因而失败，如何正确填充 HITLayoutParameters，需要为图像添加 []mturk.HITLayoutParameter参数。我尝试了一些基本 slice 等尝试，但到目前为止没有任何效果。

要进行生产，必须先创建 create a hit，然后在HIT创建过程中将布局参数放在必须插入 image_url和url本身的位置。此项的关键是 HITLayoutParameters，它接受列表类型。

经过几次尝试和错误后，这是如何执行此操作:

resp_create, err := svc.CreateHIT(&mturk.CreateHITInput{
    Title: aws.String("Title Sample"),
    Reward:   aws.String("1"),
    Description:  aws.String("Sample Desc"),
    HITLayoutId: aws.String("35EXXXXXXXXXXXXXXXXXX"),
    HITLayoutParameters: []*mturk.HITLayoutParameter{

        { Name: aws.String("image_url"), Value: aws.String("https://nationalinterest.org/sites/default/files/styles/desktop__1260_/public/main_images/fdgtrtttr.jpg?itok=RnfT8ENG")},

    },
    AssignmentDurationInSeconds: aws.Int64(604800),
    LifetimeInSeconds: aws.Int64(604800),
    Keywords:aws.String("image, identification"),
})
