没有 api-key 错误信息

【中文标题】没有 api-key 错误信息【英文标题】：no api-key error massage 【发布时间】：2018-08-02 20:35:29 【问题描述】：我尝试了很多方法和很多地方来输入 API 密钥，但在所有情况下，我都会收到错误 no-API-key。该请求在邮递员中工作正常，这意味着密钥工作正常。
我尝试过的地方：
我在这段代码中提到的地方
在快照到道路请求呼叫结束时
在所有请求调用结束时

我认为 api 密钥将作为 GET 参数包含在脚本请求中 【参考方案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>
对于网络服务
https://roads.googleapis.com/v1/speedLimits?parameters&key=YOUR_API_KEY
【讨论】：
以上是关于没有 api-key 错误信息的主要内容，如果未能解决你的问题，请参考以下文章
vs2005 SP1发布网站时发布失败,没有错误信息，没有警告信息。怎么解决啊？
