ASP.NET Core生成sitemap.xml，如何返回XML数据？

ASP.NET Core生成sitemap.xml，如何返回XML数据？记录一下踩的坑，使用ABP的朋友一定要看一下

 

先添加两个实体

 

[XmlType("url")]
    public class UrlDto
    {
        public string loc { get; set; }
        public string priority { get; set; }
        public string lastmod { get; set; }
        public string changefreq { get; set; }
    }

 

[XmlRoot(Namespace = "http://www.sitemaps.org/schemas/sitemap/0.9")]
    [XmlType("urlset")]
    public class Urlset
    {
        [XmlElement("url")]
        public List Urls { get; set; } = new List();
    }

 

再根据自己的想法添加数据即可

 

public async Task GetUrlsetAsync(string url)
        {
            return await _cacheManager.GetCache(SitemapCacheNames.CacheSitemap)
                  .GetAsync("Admin", async k =>
                  {
                      var articleIds = await _articleRepository
                      .GetAll()
                      .OrderByDescending(p => p.CreationTime)
                      .Select(p => p.Id)
                      .ToListAsync();
                      var typeIds = await _articleTypeRepository
                          .GetAll()
                          .Select(p => p.Id)
                          .ToListAsync();
                      var tagNames = await _articleTagRepository
                          .GetAll()
                          .Select(p => p.Name)
                          .ToListAsync();



                      Urlset urlset = new Urlset();
                      urlset.Urls.Add(new UrlDto() { loc = url, lastmod = DateTime.Now.ToShortDateString(), changefreq = "weekly", priority = "1.00" });
                      foreach (var item in typeIds)
                      {
                          urlset.Urls.Add(new UrlDto() { loc = $"{url}/Article/Type_{item}.html", changefreq = "weekly", priority = "1.00" });
                      }
                      foreach (var item in articleIds)
                      {
                          urlset.Urls.Add(new UrlDto() { loc = $"{url}/Article/Details_{item}.html", changefreq = "daily", priority = "0.90" });
                      }
                      foreach (var item in tagNames)
                      {
                          urlset.Urls.Add(new UrlDto() { loc = $"{url}/Article/Tag_{item}.html", changefreq = "daily", priority = "0.80" });
                      }
                      return urlset;
                  }) as Urlset;
        }

 

接下来创建控制器

 

[Route("")]
    [ApiController]
    public class SitemapController : BlogControllerBase
    {
        private readonly ISitemapAppService _sitemapAppService;
        public SitemapController(ISitemapAppService sitemapAppService)
        {
            _sitemapAppService = sitemapAppService;
        }

        [DontWrapResult]
        [HttpGet("sitemap.{format}"), FormatFilter]
        public async Task GetSitemap()
        {
            return await _sitemapAppService.GetUrlsetAsync($"https://{Request.Host}");
        }
    }

 

这里需要注意一下，如果有用ABP的朋友，这里的[HttpGet("sitemap.{format}"), FormatFilter]最好改成[HttpGet("sitemap.xml")]

如果不改的话，会导致使用不了动态WEBAPI【有更好办法的朋友请评论告诉我】

 

最后在Startup.cs添加配置了

 

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()
                .AddXmlDataContractSerializerFormatters()
                .SetCompatibilityVersion(CompatibilityVersion.Version_2_2);

 

UrlDto和Urlset两个实体一定要有无参构造函数，否则会识别不了，导致返回的数据是空的，血的教训，记录一下
