使代码一次取一个数字并嵌入其中

Question

I'm trying to use an API in my code that downloads media from Instagram posts.

The response passed by the API is as follows:

 { post1: { url: 'download url', type: 'media type' }, post2: { url: 'download url', type: 'media type' } }

post1, post2, and so on depending on the number of posts on that link (up to 10 posts).

i would like it to query and get the url of each of them.

 var resultsMedia = await apis.insta_post(link)

I tried

 resultsMedia.post[i].url

(i refers to a for function I tried, for var i = 1; ...) and I was not successful.

I would like to know how I could make the resultsMidia.post take one number at a time example: resultsMedia.post1.url, resultsMedia.post2.url, resultsMedia.post3.url, and so on.

(resultsMedia refers to the API call, post refers to the api response, and url is a parameter also present in the API response)

Answer 1

You can try this:

const postCount=Object.keys(resultsMedia).length;
for (let i = 1;i<=postCount;i++){
   console.log(resultsMedia[`post${i}`])
}

Answer 2

You can iterate using Object.entries() :

 const response = { post1: { url: 'download url 1', type: 'media type' }, post2: { url: 'download url 2', type: 'media type' } } Object.entries(response).forEach(([post, data]) => { console.log('---------------') console.log('Post:', post) console.log('Post number:', +post.replace('post', '')) console.log('Data:', data) console.log('Data url:', data.url) console.log('---------------') })
