我正在编写一个可与Google Drive API配合使用的UWP应用程序 . 我的问题似乎来自谷歌针对UWP应用程序的糟糕文档 . 在文档中它说明：
此外，您可以使用客户端ID的反向DNS概念作为自定义URI方案（例如com.googleusercontent.apps.123） .
......就在下面，它说：
对于UWP应用程序，该方案不能超过39个字符 .
这里的问题是客户端ID已超过39个字符 . 此问题没有任何补救措施，并且无法在Google Cloud Platform控制台中专门为UWP应用创建凭据 . 我没有域名，因此我无法使用其他选项进行自定义重定向uri . 我在文档中遗漏了什么吗？
以下是根据GitHub存储库中的示例重现在visual studio中设置自定义重定向uri的步骤，此处：GitHub UWP Sample：
-
打开package.appxmanifest文件 .
-
转到声明选项卡 .
-
添加协议声明 .
-
当您尝试在'Name'字段中添加客户端ID时，它将显示以下错误：
验证错误 . 错误C00CE169：应用清单验证错误：应用清单必须按架构有效：第32行，第25列，原因：'com.googleusercontent.apps.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'违反了'39'的maxLength约束 . 值为“com.googleusercontent.apps.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx”的属性“名称”无法解析 .
我因此而感到茫然 . 我无法将其他重定向URI添加到API控制台，因为它的类型为“其他” . 我尝试添加Web API凭据，Google会返回错误消息，指出该类型不允许使用自定义重定向URI .
以下是应用程序本身的代码：
