谷歌矩阵 API 的 REQUEST_DENIED

Question

我不明白我做错了什么。我的 API 已启用。

这是我的代码：

# importing required libraries
import requests, json

# enter your api key here
api_key = 'API KEY'

# Take source as input
source = 'h4n1g1'

# Take destination as input
dest = 'h4n1p8'

# url variable store url 
url = 'https://maps.googleapis.com/maps/api/distancematrix/json?'

# Get method of requests module
# return response object
r = requests.get(url + 'origins = ' + source +
                 '&destinations = ' + dest +
                 '&key = ' + api_key)

# json method of response object
# return json format result
x = r.json()

# by default driving mode considered

# print the value of x
print(x)

Google 距离 API 工作正常，但矩阵 API 不行。

删除等号之前的那些空格，如果我在你那里我也会删除等号之后的空格。

r = requests.get(url + 'origins=' + source +
             '&destinations= ' + dest +
             '&key=' + api_key)
