当我尝试访问计算机本地IIS中站点上托管的HTTP REST API时，收到以下错误消息：
HTTP请求未经授权使用客户端身份验证方案＆＃39; Anonymous＆＃39;。从服务器收到的身份验证标题是＆＃39;＆＃39;＆＃34;
在站点的IIS身份验证设置中启用匿名身份验证，并将匿名用户的身份设置为IUSR角色的身份。 IUSR角色对与我的IIS站点关联的基础虚拟目录具有读取权限，我还尝试对基础连接虚拟目录进行“Everyone”完全控制（参见下文）。虚拟目录和IIS站点都应具有足够的匿名访问身份验证。 Project Properties - Security - Permissions
此Web项目中使用的完全相同的代码在另一台计算机上运行完全正常，因此我不认为问题出在代码中。
