.NET SDK调用示例

SDK使用说明

如果需要其他语言的SDK示例代码，您可以通过OpenAPI 开发者门户在线调试工具调试API接口，该工具会自动生成相应API的SDK调用示例代码。您可以单击以下接口链接进行调试：

调试LivenessFaceVerify接口。

前提条件

• 需要使用的.NET Framework为4.5.0及以上版本或者.NET Standard为2.0及以上版本。

• 已添加认证场景，并获取对应的场景ID。具体操作，请参见添加认证场景。

安装SDK

关于.NET SDK源代码，请参见.NET SDK包。

SDK有以下两种安装方式，请选择合适的方式安装：

• 通过.NET命令行安装。

  dotnet add package AlibabaCloud.SDK.Cloudauth20190307 --version 2.0.3
  dotnet add package Aliyun.Credentials

• 使用包管理安装。

  Install-Package AlibabaCloud.SDK.Cloudauth20190307 -Version 2.0.3
  Install-Package Aliyun.Credentials
