在AspNetCore中使用极验做行为认证的验证流程

public void ConfigureServices(IServiceCollection services)

  {
    // This lambda determines whether user consent for non-essential cookies is needed for a given request.
    options.CheckConsentNeeded = context => true;
    options.MinimumSameSitePolicy = SameSiteMode.None;
  });
  // GeetestOptions中配置id 与 key
  services.AddGeetest(opt=>{
        opt.Id = "e2697c763685a34be93a7d255ee06b59";

      });
  services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
}
