背景和问题:

我正在尝试使用Google Roads API 提取某些道路的速度限制。当我尝试执行网站上描述的basic example 时,我收到错误HTTPError: HTTP Error 403: Forbidden。我正在使用以下代码:

# Import libraries
import urllib.request as req

# Extract road data
key = 'my_key'
mounted_url = 'https://roads.googleapis.com/v1/speedLimits?path=38.75807927603043,-9.03741754643809|38.6896537,-9.1770515|41.1399289,-8.6094075&key=' + key 
response = req.urlopen(mounted_url)

我尝试过的:

我已经检查了API troubleshooting section 和几个类似的问题:

Getting a 403 - Forbidden for Google Service Account 403 Forbidden Error from google API javascript client 403 Forbidden response Google API Google Drive API 403 Forbidden

我已经尝试过这些网站上给出的建议:

我的 API 密钥工作正常。如果我使用Google Directions API 提取数据,它工作得非常好:
# Extract directions data
mounted_url = 'https://maps.googleapis.com/maps/api/directions/json?origin=Disneyland&destination=Universal+Studios+Hollywood&key=' + key
response = req.urlopen(mounted_url)
我的trial 仍处于活动状态,API 已启用。

【问题讨论】:

对密钥有什么限制吗? 【参考方案1】:

您的代码没有问题。

您提供的代码与我用于执行相同测试的代码完全匹配。

您访问该 API 的权限存在帐户问题。如果您无法在设置中找到问题,建议您直接与 Google 联系。

【讨论】:

谢谢@Emerson,你是对的。这似乎是一个许可证问题。我现在正在努力。【参考方案2】:

浏览了一段时间文档后,我发现这是一个许可证问题。速度限制功能似乎是 Roads API 试用版唯一不可用的功能:
