如何在Google App Engine中导入Google Cloud语音识别（python）

我想在我的 Google App Engine python 应用程序上使用 google.cloud 库。自从我在本地安装了这个库以来，我的所有测试都在我的本地工作。我原以为 GAE 默认支持它，但它是不支持.

这是我得到的错误：

from google.cloud import speech
ImportError: No module named cloud

我查看了添加第三方库https://cloud.google.com/appengine/docs/standard/python/tools/using-libraries-python-27

按照说明进行操作后，我遇到了另一个错误。

我很难理解这个。如果您以前做过此操作，请告诉我如何在 GAE 中设置 google.cloud。

正如在另一篇 Stack Overflow 帖子中已经回答的那样在 App Engine Standard 中使用客户端库，GAE Standard 不支持 Google 客户端库，因此您可以选择灵活的应用引擎, a 计算引擎实例或与REST API（它还有一个在 App Engine Standard 中工作的 Python 库）。

如果您特别需要使用google.cloud库，您将必须使用 App Engine 灵活版而不是标准版，但如果您更愿意使用标准环境，下面我通过以下方式分享使用 Cloud Speech API 的示例 App Engine 标准应用程序的代码：Google API Python 客户端库。该库不是 GAE 标准内置的，因此您必须供应商就好像它是第三方库一样。为此，您必须创建lib本地应用程序目录中的文件夹，以及requirements.txt我在下面分享的文件，然后使用命令安装这个库pip install -t lib/ -r requirements.txt.

运行此示例 GAE 应用程序所需的文件：

要求.txt

google-api-python-client

appengine_config.py

from google.appengine.ext import vendor

# Add any libraries install in the "lib" folder.
vendor.add('lib')

app.yaml

runtime: python27
api_version: 1
threadsafe: True

handlers:
- url: /.*
  script: main.app

main.py

import webapp2
from apiclient.discovery import build
from oauth2client.client import GoogleCredentials

class MainPage(webapp2.RequestHandler):
    # Presentation page
    def get(self):
        self.response.headers['Content-Type'] = 'text/plain'
        self.response.write('This is a sample App Engine Standard application working with Cloud Speech API! :)\n\nGo to /speechAPI to transcribe your audio file (you will need to upload it to one of your Cloud Storage buckets)!')

class Recognize(webapp2.RequestHandler):
    # Working with Python API Client Library (NOT NEW CLIENT LIBRARIES)
    def get(self):
        # Add credentials
        credentials = GoogleCredentials.get_application_default()
        service = build('speech', 'v1', credentials=credentials)

        # Methods available in: https://developers.google.com/resources/api-libraries/documentation/speech/v1/python/latest/index.html
        collection = service.speech()

        # Build the data structure JSON-like
        data = {}
        data['audio'] = {}
        data['audio']['uri'] = 'gs://<BUCKET>/<FOLDER>/<FILE>'
        data['config'] = {}
        data['config']['encoding'] = '<ENCODING>'
        data['config']['languageCode'] = '<LANGUAGE_CODE>'
        data['config']['sampleRateHertz'] = <SAMPLE_RATE>

        # Build the request and execute it
        request = collection.recognize(body=data)
        res = request.execute()

        # Webapp2 Response
        self.response.headers['Content-Type'] = 'text/plain'
        self.response.write(res)


app = webapp2.WSGIApplication([
    ('/', MainPage),
    ('/speechAPI', Recognize),
], debug=True)

该应用程序也可以在本地开发服务器中运行，因此您可以使用以下命令对其进行测试dev_appserver.py app.yaml在将其部署到 App Engine 之前。
