I am working on the part of the project where people can click on a book from the search results page, which will then take them to the specific book's page.

I am getting this error:

json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

Traceback looks like:

obj, end = self.scan_once(s, idx)
During handling of the above exception, another exception occurred:

return self.wsgi_app(environ, start_response)

response = self.handle_exception(e)

reraise(exc_type, exc_value, tb)

raise value

response = self.full_dispatch_request()

rv = self.handle_user_exception(e)

reraise(exc_type, exc_value, tb)

raise value

rv = self.dispatch_request()

return self.view_functions[rule.endpoint](**req.view_args)

return f(*args, **kwargs)

output = json.loads(binary) # This is the only section of code I had a hand in writing

return _default_decoder.decode(s)

obj, end = self.raw_decode(s, idx=_w(s, 0).end())

raise JSONDecodeError("Expecting value", s, err.value) from None

Some iterations of the code I have tried include:

    response = requests.get("https://www.goodreads.com/book/review_counts.json", params={"key": key, "isbns": isbn})
    source = response.read()
    data = json.loads(source)
    reviews_count = jsonResponse["books"][0]["reviews_count"]
    average_rating = jsonResponse["books"][0]["average_rating"]
    response = requests.get("https://www.goodreads.com/book/review_counts.json", params={"key": key, "isbns": isbn})
    binary = response.content
    output = json.loads(binary)
    reviews_count = output["books"][0]["reviews_count"]
    average_rating = output["books"][0]["average_rating"]

as well as trying the books.reviews_count format. I (think) I tried to convert the json object to a python object, but that didn't seem to work either.

I'm looking to get the reviews_count and average_rating so I can show it on the book info page (ex: "this book has 4.32 stars based on 356,900 reviews").

I am thinking I am unable to select the part of the json object I want, and I simply don't know the proper formatting. Does that sound right, or have I made a mistake somewhere else?

I had trouble with this part as well and I finally did it like this:

res = requests.get("https://www.goodreads.com/book/..................)

goodinfo = res.json()

scratch = goodinfo["books"]

reviews_count = scratch[0]["work_ratings_count"]

average_rating = scratch[0]["average_rating"]

  • It seems to work when I do a separate test.py run... prints all the information I want! However, it is causing issues in the bigger application.py. Thanks for the tip!
