Question

我已经尝试了许多方法和许多地方输入API密钥，但在所有情况下，我得到错误no-API-key。邮递员的请求工作正常，这意味着密钥可以正常工作。

我试过的地方：

我在此代码中提到的
在对话请求呼叫结束时
在所有请求调用结束时

Answer 1

在加载JS api的脚本中

<script src="https://maps.googleapis.com/maps/api/js?libraries=drawing,places&key=your_api_key"></script>

和Web服务

https://roads.googleapis.com/v1/speedLimits?parameters&key=YOUR_API_KEY

没有api-key错误按摩
