python - 如何从 Google 图书 api 获取作者姓名？

问题描述

当我使用此链接https://www.googleapis.com/books/v1/volumes?q=9780310709626搜索这本书时，我会在详细信息中获得作者姓名。

但是，当我运行我的代码并打印项目时，我看不到作者姓名。我一直在试图弄清楚为什么它没有从数据中显示出来，但我没有看到我的代码有任何问题。

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"])

我的代码输出：

解决方案

与requests图书馆：

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'])

从响应中您可以看到这authors是一个数组。要到达该数组，您需要执行json['items'][0]['volumeInfo']['authors'].

Asitems也是一个数组，这意味着此响应中可能有多个项目。您可能想要编写额外的代码来处理除硬代码之外的其他代码index=0。

请注意，在这种情况下，您可能不知道响应的架构。您应该处理意外行为。对于某些书籍，可能缺少某些键，json['items']可能是空数组，甚至items根本不在响应中。
