code explain
construction
public StudyStartup(IConfiguration configuration)
相关源码
IWebHostBuilder webHostBuilder = WebHost.CreateDefaultBuilder(args);
方法解析
public static IWebHostBuilder CreateDefaultBuilder(string[] args)
{
return new WebHostBuilder()
.UseKestrel()//Specify Kestrel as the server to be used by the web host.
.UseContentRoot(Directory.GetCurrentDirectory())//采用当前目录作为内容跟目录
//配置信息处理
.ConfigureAppConfiguration((Action<WebHostBuilderContext, IConfigurationBuilder>) ((hostingContext, config) =>
{
//注入运行环境
IHostingEnvironment hostingEnvironment = hostingContext.HostingEnvironment;
//加载配置文件
config.AddJsonFile("appsettings.json", true, true).AddJsonFile(string.Format("appsettings.{0}.json", (object) hostingEnvironment.EnvironmentName), true, true);
//根据运行环境加载相应文件
if (hostingEnvironment.IsDevelopment())
{
Assembly assembly = Assembly.Load(new AssemblyName(hostingEnvironment.ApplicationName));
if (assembly != (Assembly) null)
config.AddUserSecrets(assembly, true);
}
config.AddEnvironmentVariables();
if (args == null)
return;
config.AddCommandLine(args);
}))
//配置日志信息
.ConfigureLogging((Action<WebHostBuilderContext, ILoggingBuilder>) ((hostingContext, logging) =>
{
logging.AddConfiguration((IConfiguration) hostingContext.Configuration.GetSection("Logging"));
logging.AddConsole();
logging.AddDebug();
}))
.UseIISIntegration()//采用IIS进行发布
.UseDefaultServiceProvider((Action<WebHostBuilderContext, ServiceProviderOptions>) ((context, options) => options.ValidateScopes = context.HostingEnvironment.IsDevelopment()));//采用默认的处理机制
}
即若需要使用startup的有参构造，则需要在configureappconfiguration中进行配置相应处理类
请求走向:
初始:Run --> ConfigureServices --> Configure
配置信息的获取:
<Controller>
protected AppSetting ConfigInfo { get; set; }
//读取配置信息
protected BaseController(IOptions<AppSetting> options) => ConfigInfo = options.Value;
DI注入
1.创建的DI注入在ConfigureServices进行处理
注入方式：
services.AddSingleton(u => new MonsterDIController(new GuestDal()));//指定控制器进行注入
services.AddSingleton<IDal,DefaultDal>();//统一注入 全局共享一个
services.AddTransient<IDal, DefaultDal>();//统一注入 每次使用都不一样，不同的类或不同的方法使用都不一样
services.AddScoped<IDal, EmptyDal>();//统一注入 一次请求共享一个对象
注：
当对同一类型构造传入不同类型对象的注入时，
不考虑注入类型或范围
已最终注入类型为传入对象创建实例
例如:
<Controller>
protected IDal Dal { get; set; }
public MonsterDIController(IDal dal)
{
this.Dal = dal;
}
<ConfigureServices>
如上述一致
<Result>
最终创建实例时，会传入EmptyDal
开启Session功能：
<method --> ConfigureServices>
services.AddSession(options => {
options.IdleTimeout = TimeSpan.FromMinutes(30);//存储时长
});
<method --> Configure >
// 重要: session的注册必须在UseMvc之前，因为MVC里面要用
app.UseSession();
