I’m consuming a Google Books API and I’m trying to return a search result with multiple books. Here’s what I’m doing:
def lookup(search): """Look up search for books.""" # Contact API try: url = f'https://www.googleapis.com/books/v1/volumes?q={search}&key=myAPIKey' response = requests.get(url) response.raise_for_status() except requests.RequestException: return None # Parse response try: search = response.json() return { "totalItems": int(search["totalItems"]), "title": search["items"][0]['volumeInfo']['title'], "authors": search["items"][0]['volumeInfo']['authors'], } except (KeyError, TypeError, ValueError): return None
Of course, this only returns one result. However, if I try to call it this way:
"title": search["items"]['volumeInfo']['title']
It doesn’t return anything.
Example of JSON to be consumed.
How do I receive all results?
Another ‘problem’ that I’ve been facing is how to get a thumbnail of that same JSON, because apparently it doesn’t work:
"thumbnail": search["items"][1]['volumeInfo']['imageLinks']['thumbnail']

You need to iterate through the response get the values. You can change your try: to the following and this will give lists of titles and authors. If you want something different you can adapt it.
try: search = response.json() titles = [] authors = [] for itm in search['items']: titles.append(itm['volumeInfo']['title']) authors.append(itm['volumeInfo']['authors']) return { "totalItems": int(search["totalItems"]), "title": titles, "authors": authors, }
Thumbnails captured like this:
thumbnails = [] for itm in search['items']: thumbnails.append(itm['volumeInfo']['imageLinks']['thumbnail'])
