我有一个来自Google开发者控制台的API密钥。 如何在pyton中输入API键值

编辑：尝试了skycrew提供的解决方案，但现在得到的错误是googlemaps不是受支持的API项目

>>> from googlemaps import Client
>>> mapService = Client("AInotqjpmyvA7realBIy-keymA9u0")
>>> directions = mapService.directions('Toronto', 'Montreal')

您需要根据下面的docstring将密钥传递给

客户端（）

函数：

Help on class Client in module googlemaps.client:

class Client(__builtin__.object)
 |  Performs requests to the Google Maps API web services.
 |  
 |  Methods defined here:
 |  
 |  __init__(self, key=None, client_id=None, client_secret=None, timeout=None, connect_timeout=None, read_timeout=None, retry_timeout=60, requests_kwargs=None, queries_per_second=10)
 |      :param key: Maps API key. Required, unless "client_id" and
 |          "client_secret" are set.
 |      :type key: string
 |      
 |      :param client_id: (for Maps API for Work customers) Your client ID.
 |      :type client_id: string
 |      
 |      :param client_secret: (for Maps API for Work customers) Your client
 |          secret (base64 encoded).
 |      :type client_secret: string
 |      
 |      :param timeout: Combined connect and read timeout for HTTP requests, in
 |          seconds. Specify "None" for no timeout.
 |      :type timeout: int
 |      
 |      :param connect_timeout: Connection timeout for HTTP requests, in
 |          seconds. You should specify read_timeout in addition to this option.
 |          Note that this requires requests >= 2.4.0.
 |      :type connect_timeout: int
 |      
 |      :param read_timeout: Read timeout for HTTP requests, in
 |          seconds. You should specify connect_timeout in addition to this
 |          option. Note that this requires requests >= 2.4.0.
 |      :type read_timeout: int
 |      
 |      :param retry_timeout: Timeout across multiple retriable requests, in
 |          seconds.
 |      :type retry_timeout: int
 |      
 |      :param queries_per_second: Number of queries per second permitted.
 |          If the rate limit is reached, the client will sleep for the
 |          appropriate amount of time before it runs the current query.
 |      :type queries_per_second: int
 |      
 |      :raises ValueError: when either credentials are missing, incomplete
 |          or invalid.
 |      :raises NotImplementedError: if connect_timeout and read_timeout are
 |          used with a version of requests prior to 2.4.0.
 |      
 |      :param requests_kwargs: Extra keyword arguments for the requests
 |          library, which among other things allow for proxy auth to be
 |          implemented. See the official requests docs for more info:
 |          http://docs.python-requests.org/en/latest/api/#main-interface
 |      :type requests_kwargs: dict

所以你可以这样做：

mapService = Client("you_key", "your_client_id", "your_client_secret")

我使用它的方式如下，正如前面所说，您需要在客户机类中传递API密钥

你会注意到，在代理背后工作时，我必须传递更多的参数，但如果你不是在这种情况下，就没有必要了

import googlemaps
GOOGLE_MAP_KEY = 'yourkey'
PROXY = {'proxies': {"https": "https://user:password@proxyurl:proxyport/"}}
gmaps = googlemaps.Client(GOOGLE_MAP_KEY, requests_kwargs=PROXY)
results = gmaps.geocode(address=search)

现在，您的错误似乎来自您没有正确注册API的事实。

转到并查看左侧的凭据链接，单击它并添加一个API密钥，您应该进行设置

这对您有效吗？我只尝试了密钥，因为我没有客户端id或客户端机密，只有来自Google的API密钥。我得到一个错误，说这不是一个授权的项目。你能正确使用这个库吗？

import googlemaps
GOOGLE_MAP_KEY = 'yourkey'
PROXY = {'proxies': {"https": "https://user:password@proxyurl:proxyport/"}}
gmaps = googlemaps.Client(GOOGLE_MAP_KEY, requests_kwargs=PROXY)
results = gmaps.geocode(address=search)
