的Python的Youtube API客戶端警告

Question

TLDR，使用google-api-python-client，它給了我一些警告，

WARNING:googleapiclient.discovery_cache:file_cache is unavailable when using oauth2client >= 4.0.0 
Traceback (most recent call last): 
    File "/home/user/.virtualenvs/tmp/lib/python3.6/site-packages/googleapiclient/discovery_cache/__init__.py", line 36, in autodetect 
    from google.appengine.api import memcache 
ModuleNotFoundError: No module named 'google' 

我想隱藏起來。我如何隱藏它們？

詳細

我使用google-api-python-client==1.6.2執行使用YouTube data API搜索。在這種情況下，我不需要OAuth，所以除了google-api-python-client之外我沒有安裝任何東西。

當我運行我的代碼時，我得到了一個很長的警告與幾個回溯。我的應用程序仍在運行，因爲我仍然可以使用curl命中服務器並獲得結果。

WARNING:googleapiclient.discovery_cache:file_cache is unavailable when using oauth2client >= 4.0.0

During handling of the above exception, another exception occurred:

這裏是我的代碼，

my_package/main.py

from my_package.server import app 

HOST = 'localhost' 
PORT = 8100 
app.run(HOST, PORT) 

my_package/server.py

from flask import Flask, request 
from flask_restful import Resource, Api 
from logging import info 
from my_package.youtube import YouTube 


app = Flask(__name__) 
api = Api(app) 

yt_client = YouTube() 


class Search(Resource): 
    def get(self, query): 
     info("Handling `get` request for the resource 'Search'.") 
     return yt_client.search(query) 

api.add_resource(Search, '/search/<string:query>') 


if __name__ == '__main__': 
    info('Application starting.') 
    app.run(debug=True) 

my_package/youtube.py

from logging import info 
import apiclient as google 


class YouTube: 
    MAX_RESULTS = 25 

    def __init__(self): 
     info('Creating a YouTube API instance.') 
     self.API_KEY = 'MY_API_KEY' 
     self.youtube = google.discovery.build('youtube', 'v3', 
               developerKey=self.API_KEY) 

    def search(self, query): 
     info(f"Performing a search for '{query}'") 
     results = self.youtube.search().list(
      q=query, 
      part='snippet', 
      maxResults=self.MAX_RESULTS 
     ).execute() 

     return results.get('items', [])

Answer 1

設置cache_discovery參數在構建呼叫假。

google.discovery.build('youtube','v3',developerKey=self.API_KEY, 
         cache_discovery=False) 

這將阻止導入正在記錄警告的cache.discovery模塊。
