GAE google books api

Question

我正在使用Python 2.7.11創建一個GAE應用程序。 這是我構建GAE應用程序的第一個項目，我也是Web開發的新手。 鏈接在這里 。 我正在嘗試訪問Google圖書的API以檢索圖書信息。 在本地部署時，一切都完美無瑕。 我在搜索字段中輸入一本書的名字，我的處理程序飛走了，點擊2個Google API（搜索，然后是音量），解析結果並將其附加到頁面。

當我將我的應用程序部署到GAE時，我收到以下錯誤（帶有堆棧跟蹤）：

   Traceback (most recent call last):

以下是執行API調用的代碼部分。 （這很草率，對不起。我剛剛在清理代碼之前嘗試解決這個問題）。

  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")

根據Google的API文檔，這些API僅訪問公共數據，因此不需要OAuth或API密鑰。 不用說，那沒用。 我添加了我的API密鑰，但仍無效。 我已從開發者控制台啟用了Google Books API。 唯一留給我的是Oauth，但是我的腦袋正在旋轉，試圖閱讀文檔頁面上的頁面，其中一些頁面彼此截然不同，所以我不知道要實現什么。 Web應用程序不需要任何類型的登錄，API請求僅使用公共數據。 謝謝。

有人可以提供幫助嗎？

編輯：這是我從Google控制台日志中提取的從Google返回的日志部分。 第一部分是logging.info所示的確切URL。

對於未來的斗爭者，請務必在您的請求中添加適當的國家/地區字符串

&country=US

Books API使用客戶端的IP地址來對用戶進行地理定位。 由於我們必須遵守來自不同國家/地區的版權法，並且擁有發布商的國家/地區特定權利，因此我們需要知道請求來自哪個國家/地區，以便提供適當的內容。
