Google 道路 API - HTTP 错误 403：禁止访问

Question

上下文和问题：

我正在尝试使用网站上描述的 Google Roads API. When I try to execute the basic example 提取某些道路的速度限制，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

而且我已经尝试过这些网站上给出的建议：

我的 API 键工作正常。如果我使用 Google Directions API 提取数据，它工作得很好：

# 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 is still active and the API 已启用。

额外的细节：

这是完整的错误：

Answer 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，我建议您直接联系 Google。

Answer 2

在查阅文档一段时间后，我发现这是一个许可证问题。限速功能似乎是 Roads API 试用版唯一不可用的功能：
