.net core将URL请求格式化为XML或JSON(网站动态生成sitemap.xml)

首先设置 Startup.cs 文件

• 配置 ConfigureServices

            services.AddMvc(options =>{options.RespectBrowserAcceptHeader = true;options.OutputFormatters.Add(new XmlSerializerOutputFormatter());options.FormatterMappings.SetMediaTypeMappingForFormat("xml", Microsoft.Net.Http.Headers.MediaTypeHeaderValue.Parse("application/xml"));options.FormatterMappings.SetMediaTypeMappingForFormat("config", Microsoft.Net.Http.Headers.MediaTypeHeaderValue.Parse("application/xml"));options.FormatterMappings.SetMediaTypeMappingForFormat("js", Microsoft.Net.Http.Headers.MediaTypeHeaderValue.Parse("application/json"));}).AddXmlSerializerFormatters().AddDataAnnotationsLocalization().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);

例子：生成sitemap.xml

• 返回值 Urlset

using System.Collections.Generic;
using System.Xml.Serialization;namespace MyFramework.Services.Sitemaps.Dtos
{[XmlRoot(Namespace = "http://www.sitemaps.org/schemas/sitemap/0.9")][XmlType("urlset")]public class Urlset{[XmlElement("url")]public List<Url> Urls { get; set; }}
}

using System.Xml.Serialization;namespace MyFramework.Services.Sitemaps.Dtos
{[XmlType("url")]public class Url{public string loc { get; set; }public string priority { get; set; }public string lastmod { get; set; }public string changefreq { get; set; }}
}

• GetUrlset 方法

using MyFramework.Services.Sitemaps.Dtos;
using System;
using System.Collections.Generic;namespace MyFramework.Services.Sitemaps
{public class SitemapService : ServiceBaseModule, ISitemapService{public Urlset GetUrlset(){var __baseUrl = new List<Url>{new Url{ loc="http://www.mywebsite.com",priority="1.00",lastmod= DateTime.Now.AddDays(-1).ToString("yyyy-MM-dd"),changefreq="weekly"},new Url{ loc="http://www.mywebsite.com/Home",priority="1.00",lastmod= DateTime.Now.AddDays(-1).ToString("yyyy-MM-dd"),changefreq="weekly"},new Url{ loc="http://www.mywebsite.com/Home/Index.html",priority="1.00",lastmod= DateTime.Now.AddDays(-1).ToString("yyyy-MM-dd"),changefreq="weekly"},};for (var i = 0; i < 10; i++){__baseUrl.Add(new Url { loc = "http://www.mywebsite.com/news/news-" + i + ".html", priority = "1.00", lastmod = DateTime.Now.AddDays(-1).ToString("yyyy-MM-dd"), changefreq = "daily" });}var __urlset = new Urlset{Urls = __baseUrl};return __urlset;}}
}

• SitemapController Controller

using Microsoft.AspNetCore.Mvc;
using MyFramework.Services.Sitemaps;
using MyFramework.Services.Sitemaps.Dtos;namespace MyFramework.Web.Api.Controllers
{[Route("")][ApiController]public class SitemapController : ControllerBase{#region Initializeprivate readonly ISitemapService _sitemapService;public SitemapController(ISitemapService sitemapService){_sitemapService = sitemapService;}#endregion#region Methods[HttpGet("sitemap.{format}"), FormatFilter]public Urlset GetSitemap(){return _sitemapService.GetUrlset();}#endregion}
}

最终效果如图
