如何在 asp.net 内核中编写一个中间件作为自定义路由器?
How to write a middleware as custom router in asp.net core?
我要改造这段代码:
var trackPackageRouteHandler = new RouteHandler(context =>
{
var routeValues = context.GetRouteData().Values;
return context.Response.WriteAsync(
$"Hello! Route values: {string.Join(", ", routeValues)}");
});
var routeBuilder = new RouteBuilder(app, trackPackageRouteHandler);
routeBuilder.MapRoute(
"Track Package Route",
"package/{operation:regex(^track|create|detonate$)}/{id:int}");
routeBuilder.MapGet("hello/{name}", context =>
{
var name = context.GetRouteValue("name");
// This is the route handler when HTTP GET "hello/<anything>" matches
// To match HTTP GET "hello/<anything>/<anything>,
// use routeBuilder.MapGet("hello/{*name}"
return context.Response.WriteAsync($"Hi, {name}!");
});
var routes = routeBuilder.Build();
app.UseRouter(routes);
进入这个:
app.UseHelloRouter();
但是除了路由
我不想使用任何服务
您可以创建一个扩展方法来封装路由器配置
public static class HelloRouterExtensions {
public static IApplicationBuilder UseHelloRouter(this IApplicationBuilder app) {
var trackPackageRouteHandler = new RouteHandler(context => {
var routeValues = context.GetRouteData().Values;
return context.Response.WriteAsync(
$"Hello! Route values: {string.Join(", ", routeValues)}");
});
var routeBuilder = new RouteBuilder(app, trackPackageRouteHandler);
routeBuilder.MapRoute(
"Track Package Route",
"package/{operation:regex(^track|create|detonate$)}/{id:int}");
routeBuilder.MapGet("hello/{name}", context => {
var name = context.GetRouteValue("name");
// This is the route handler when HTTP GET "hello/<anything>" matches
// To match HTTP GET "hello/<anything>/<anything>,
// use routeBuilder.MapGet("hello/{*name}"
return context.Response.WriteAsync($"Hi, {name}!");
});
var routes = routeBuilder.Build();
app.UseRouter(routes);
return app;
}
}
基本就是这样转的配置
public void Configure(IApplicationBuilder app, ILoggerFactory loggerFactory)
{
var trackPackageRouteHandler = new RouteHandler(context =>
{
var routeValues = context.GetRouteData().Values;
return context.Response.WriteAsync(
$"Hello! Route values: {string.Join(", ", routeValues)}");
});
var routeBuilder = new RouteBuilder(app, trackPackageRouteHandler);
routeBuilder.MapRoute(
"Track Package Route",
"package/{operation:regex(^track|create|detonate$)}/{id:int}");
routeBuilder.MapGet("hello/{name}", context =>
{
var name = context.GetRouteValue("name");
// This is the route handler when HTTP GET "hello/<anything>" matches
// To match HTTP GET "hello/<anything>/<anything>,
// use routeBuilder.MapGet("hello/{*name}"
return context.Response.WriteAsync($"Hi, {name}!");
});
var routes = routeBuilder.Build();
app.UseRouter(routes);
}
