GAE google books api

标签： python api google-app-engine google-books

我正在使用Python 2.7.11制作GAE应用。这是我构建GAE应用程序的第一个项目，我也是Web开发的新手。 Link here。我正在尝试访问Google图书的API以检索图书信息。在本地部署时，一切都完美无瑕。我在搜索字段中输入了一本书的名字，我的处理程序飞了，点击2个Google API（搜索，然后是音量），解析结果并将其附加到页面。

当我将我的应用程序部署到GAE时，我收到以下错误（带有堆栈跟踪）：

   Traceback (most recent call last):

以下是执行API调用的代码部分。 （它非常草率，抱歉。我在清理代码之前一直试图解决这个问题。）

  headers = {'Accept': 'application/json'}      
  book = Book(parent=books_key)
  book.name = self.request.get('name')
  googleBookSearch = "https://www.googleapis.com/books/v1/volumes?q="
  googleBookVol = "https://www.googleapis.com/books/v1/volumes/ID"
  escapedBookName = urllib.quote(book.name)
  apiCall = googleBookSearch + escapedBookName + "&" + api_key2
  request = Request(apiCall, headers=headers)
  response_body = urlopen(request).read()
  parsed_book = json.loads(response_body)
  if parsed_book['totalItems'] != 0:
    volumeID = parsed_book['items'][0]['id']
    googleBookVol = googleBookVol.replace("ID", volumeID)
    googleBookVol = googleBookVol + "?" + api_key2
    logging.info(googleBookVol)
    request = Request(googleBookVol, headers=headers)
    response_body = urlopen(request).read()
    response_body = json.loads(response_body)
    book.name = response_body['volumeInfo']['title']
    pageCount = response_body['volumeInfo']['pageCount']
    book.pages = int(pageCount)
    bookCover = response_body['volumeInfo']['imageLinks']['smallThumbnail']
    book.cover = str(bookCover)
    book.published = str(response_body['volumeInfo']['publishedDate'])
    book.author = str(response_body['volumeInfo']['authors'][0])
    book.put()
    self.redirect("/books")

根据Google的API文档，这些API仅访问公共数据，因此不需要OAuth或API密钥。不用说，那不起作用。我已经添加了我的API密钥，但仍然没有用。我已从开发者控制台启用了Google Books API。唯一留给我的是Oauth，但是我的脑袋正在旋转，试图阅读文档页面上的页面，其中一些页面彼此截然不同，所以我不知道要实现什么。 Web应用程序不需要任何类型的登录，API请求仅使用公共数据。感谢。

有没有人可以提供帮助？

编辑：这是我从Google控制台日志中提取的从谷歌回来的日志部分。第一部分是确切的URL，如logging.info。

对于未来的挣扎者，请务必在请求中添加相应的国家/地区字符串

&country=US

  

Books API使用客户端的IP地址对用户进行地理定位。由于我们必须遵守各国的版权法，并且拥有发布商的国家/地区特定权利，因此我们需要知道请求所在的国家/地区，以便提供适当的内容。
