//session

services.AddDistributedSqlServerCache(options =>

{

options.ConnectionString = Configuration.GetConnectionString("BoxDbcontext");

options.SchemaName = "dbo";

options.TableName = "global_cache";

});

var x = Configuration.GetConnectionString("BoxDbcontext");

services.AddDbContext<DataProtectionDbContext>(options =>options.UseSqlServer(Configuration.GetConnectionString("BoxDbcontext")));

// Register XmlRepository for data protection.

services.AddOptions<KeyManagementOptions>()

.Configure<IServiceScopeFactory>((options, factory) =>

{

options.XmlRepository = new CustomXmlRepository(factory);

});

//redis存储

//var redis = ConnectionMultiplexer.Connect("localhost:6379");

//services.AddDataProtection().ProtectKeysWithDpapi().PersistKeysToRedis(redis, "DataProtection-Keys");

//文件存储

//将秘钥存储在本地，只能用于单台服务器上部署多个站点,站点之间的cookie数据共享

//services.AddDataProtection().PersistKeysToFileSystem(new DirectoryInfo(@"E:\xml"));

//存储在UNC（Universal Naming Convention）网络共享服务器目录，可以用于多个服务器共享

//services.AddDataProtection().PersistKeysToFileSystem(new DirectoryInfo(@"\\server\share\xml\");

//存储在程序里ok

//services.Configure<KeyManagementOptions>(options =>

//{

// options.XmlRepository = new MyCustomXmlRepository();

//});

//=====

//services.AddSingleton<IXmlRepository, MyCustomXmlRepository>();

//var sp = services.BuildServiceProvider();

//services.AddDataProtection().AddKeyManagementOptions(o => o.XmlRepository = sp.GetService<IXmlRepository>()).SetApplicationName("kszx");

//===ok

//services.AddSingleton<IConfigureOptions<KeyManagementOptions>>(services =>

//{

// return new ConfigureOptions<KeyManagementOptions>(options =>

// {

// options.XmlRepository = new MyCustomXmlRepository();

// });

//});

//==ok

//services.AddOptions<KeyManagementOptions>().Configure<IServiceScopeFactory>((options, factory) =>

//{

// options.XmlRepository = new MyCustomXmlRepository();

//});

//// 在ConfigureServices中配置数据保护

//services.AddDataProtection(x => x.ApplicationDiscriminator = "session_application_name");

////或者用这样的写法，效果是一样的

//services.AddDataProtection().SetApplicationName("session_application_name");
