如何从 Google 图书 api 中获取作者姓名？

Question

When I search for the book using this link https://www.googleapis.com/books/v1/volumes?q=9780310709626 I get the author name in the details

However when I run my code and print items I don't see the author name. I've been trying to figure out why it the data doesn't show but I don't see any problem with my code

print(searchBooks("9780310709626"))
def getBooks(id):
      url = "https://www.googleapis.com/books/v1/volumes?q=isbn:"
       resp = url(api + id)
       data = json.load(resp)
       print(data["items"])

code output

Answer 1

With the requests library:

import requests

url = 'https://www.googleapis.com/books/v1/volumes?q=9780310709626'
resp = requests.get(url)
json = resp.json()

print(json['items'][0]['volumeInfo']['authors'])

From the response you can see that authors is an array. To reach that array you will need to do json['items'][0]['volumeInfo']['authors'] .

As items is also an array, meaning that there could be multiple items in this response. You might want to write extra code to deal with that other than hard-code index=0 .

Note that in this case, you probably won't know the schema of the response. You should handle unexpected behaviors . For some certain books maybe some keys are missing, json['items'] could be an empty array, or even items is not in the response at all.
