GAE 谷歌图书 api答案

【问题描述】：

我正在使用 Python 2.7.11 制作一个 GAE 应用程序。这是我第一个构建 GAE 应用程序的项目，我也是 Web 开发的新手。 Link here。我正在尝试访问 Google Book 的 API 以检索图书信息。在本地部署时，一切都完美无缺。我在搜索字段中输入一本书的名字，我的处理程序飞走，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):

这是我执行 API 调用的代码部分。（很草率，抱歉。我在清理代码之前一直在尝试解决这个问题）。

  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 仅用于访问公共数据，因此不需要 OAuth 或 API 密钥。不用说，那没有用。我添加了我的 API 密钥，但仍然无法正常工作。我已经从开发者控制台启用了 Google Books API。留给我的唯一东西是 Oauth，但我头晕目眩，试图阅读一页又一页的文档，其中一些文档彼此大不相同，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。谢谢。

有人可以帮忙吗？

编辑：这是我从 Cloud Console 日志中提取的从 Google 返回的日志部分。第一部分是确切的 URL，如 logging.info 所示。

【问题讨论】：

您能否提供来自 Google Book API 的完整响应？
谢谢，请尝试在您的查询字符串中添加&country=US（或您所在的国家/地区）。
哇，成功了。好心疼！这几天一直困扰着我。我不记得在原籍国的文件中阅读需要在那里，但也许我错过了一些东西。非常感谢！

【解决方案1】：

对于未来的奋斗者，请确保在您的请求中添加适当的国家/地区字符串

&国家=美国

Books API 使用客户端的 IP 地址来定位用户。由于我们必须遵守各个国家/地区的版权法，并拥有发布商针对特定国家/地区的权利，因此我们需要了解请求来自哪个国家/地区，以便提供适当的内容。
