在做 requests.get () 請求時出現 Cannot connect to proxy 的錯誤。

錯誤信息為：

Traceback (most recent call last): ?File "C:\Python38\lib\site-packages\requests\adapters.py", line 489, in send ? ?resp = conn.urlopen( ?File "C:\Python38\lib\site-packages\urllib3\connectionpool.py", line 785, in urlopen ? ?retries = retries.increment( ?File "C:\Python38\lib\site-packages\urllib3\util\retry.py", line 592, in increment ? ?raise MaxRetryError(_pool, url, error or ResponseError(cause)) urllib3.exceptions.MaxRetryError: HTTPSConnectionPool(host='cn.bing.com', port=443): Max retries exceeded with url: /HPImageArchive.aspx?format=js&idx=0&n=1 (Caused by ProxyError('Cannot connect to proxy.', FileNotFoundError(2, 'No such file or directory'))) During handling of the above exception, another exception occurred: Traceback (most recent call last): ?File "f:/Project/api/main.py", line 45, in <module> ? ?get_bing_daily_img() ?File "f:/Project/api/main.py", line 39, in get_bing_daily_img ? ?api_rets = requests.get(api_url, verify=False) ?File "C:\Python38\lib\site-packages\requests\api.py", line 73, in get ? ?return request("get", url, params=params, **kwargs) ?File "C:\Python38\lib\site-packages\requests\api.py", line 59, in request ? ?return session.request(method=method, url=url, **kwargs) ?File "C:\Python38\lib\site-packages\requests\sessions.py", line 587, in request ? ?resp = self.send(prep, **send_kwargs) ?File "C:\Python38\lib\site-packages\requests\sessions.py", line 701, in send ?File "C:\Python38\lib\site-packages\requests\adapters.py", line 559, in send ? ?raise ProxyError(e, request=request) requests.exceptions.ProxyError: HTTPSConnectionPool(host='cn.bing.com', port=443): Max retries exceeded with url:

解決方案：

在進行 requests.get (url) 方法調用前，請設置目標 url 的代理過濾， 例如：

os.environ['NO_PROXY'] = "cn.bing.com"?

api_rets = requests.get(api_url, verify=False)
