我正在尝试将Google登录集成到我的iOS应用中。 成功登录后，我可以在应用程序中显示登录按钮并获取设备身份验证令牌。
我的后端正在Google App引擎上运行。 我正在将设备身份验证令牌发送到后端，并尝试使用https://developers.google.com/identity/sign-in/ios/backend-auth中的示例代码来验证令牌。
但是，当后端尝试执行client.verify_id_token验证令牌时，我遇到了帖子结尾处显示的错误。
日志中的错误如下。 在Stackoverflow上进行的一些搜索表明，如果启用pyOpenSSL，问题将消失。 我该怎么做呢？
还有一个问题可能是此失败的根本原因。 我需要为https://developers.google.com/identity/sign-in/ios/backend-auth中的代码中的CLIENT_ID和IOS_CLIENT_ID字段使用什么值？
当前，我正在com.apm.smartiothome.chatime的开发人员控制台-> APIs和Auth->凭据-> OAuth 2.0客户端ID-> iOS客户端下列出客户端ID。 这个对吗？ 另外，我是否需要在开发人员控制台中选中此复选框旁边的复选框？
