.NET 中的 Swagger 文档排序设置

Swagger的API默认排序往往达不到效果，甚至设置了Action排序也没有作用。这里直接给出代码，关键在于 IDocumentFilter 实现。

注意 DocumentFilter 注册要放在尾部，否则获取不到分组Tag信息

services.AddSwaggerGen();
services.AddOptions<SwaggerGenOptions>().Configure<IOptions<ProjectOptions>>((c, pOptions) =>
{
c.SwaggerDoc("v1", new OpenApiInfo
{
    Title = $"{proj.Code} ({proj.Profile})",
    Version = proj.Version,
    Description = proj.Title
});

var basePath = AppContext.BaseDirectory;
var xmlPath = Path.Combine(basePath, $"{proj.NsPrefix}.Model.xml");
if (File.Exists(xmlPath))
{
    c.IncludeXmlComments(xmlPath);
}
xmlPath = Path.Combine(basePath, $"{proj.NsPrefix}.WebApi.xml");
if (File.Exists(xmlPath))
{
    c.IncludeXmlComments(xmlPath, true);
}// 设置分组排序
c.DocumentFilter<OrderTagsDocumentFilter>();
// 设置API排序
c.OrderActionsBy(desc => desc.RelativePath);
});

/// <summary>
/// 文档按控制器分组
/// </summary>
public class OrderTagsDocumentFilter : IDocumentFilter
{
    /// <summary>
    /// 设置
    /// </summary>
    /// <param name="swaggerDoc"></param>
    /// <param name="context"></param>
    public void Apply(OpenApiDocument swaggerDoc, DocumentFilterContext context)
    {
        swaggerDoc.Tags = swaggerDoc.Tags.OrderBy(x => x.Name).ToList();
    }
}
