我有以下逻辑：
服务器端进行地点搜索网络服务调用并获取有效的唯一跨 Google 地图 API 的PlaceId字符串。检查：从他那里手动构造地点详细信息PlaceId的 URL（返回）返回预期的结果Place，表明他在 Google 的地点数据库中有照片（photos[]结果 Json 不为空......）。
因此，现在服务器将此发送到 Android 客户端，并在 android 中我对Places PhotosPlaceId进行 API 调用以获取至少一张图像。它应该可以工作，因为它是所有谷歌地图产品的唯一地点标识符。工作流程基于 Google 官方示例非常简单，如代码中的注释所示，连接部分成功，所有 API 设置都很好（在开发控制台中，清单等）。PlaceIdAPI KEY
问题是它不起作用：在开发控制台中，我看到使用次数增加，并且在我希望获取图像的代码中没有任何反应 - 结果是PlaceId我尝试的任何东西（如上所述应该有照片）在 Google 的数据库中没有任何照片。也不是要调试的异常或类似的东西。问题出在哪里？谢谢，
