/grpc/ 。当以/结尾或为空值时，自动添加index 。然后得到路径/grpc/index 。
如果存在多语言，则于路径末尾添加.{lang} ， {lang}为当前语言值 。最后于末尾添加.md扩展名 。得到路径/grpc/index.zh-cn.md 。
如果存在路径地址，则于路径前添加/{path}路径地址 。得到路径/docs/grpc/index.zh-cn.md 。
如果存在多版本 ， 则于路径前添加/{version}，{version}为版本路径 。得到路径/main/docs/grpc/index.zh-cn.md
最后于路径前添加{baseUrl}基础地址 。得到路径https://raw.githubusercontent.com/who/project/main/docs/grpc/index.zh-cn.md 。
DocMarkdown将请求该地址以获取Markdown文档内容并解析生成Html内容展现出来 。
解析与渲染markdig能解析Markdown内容并返回一系列不同类型的对象，根据这些对象的类型，我们可以生成想要的内容对应的Razor组件
定义一个MarkdownRenderer用于解析对应类型的对象
public abstract class MarkdownRenderer{public abstract bool CanRender(MarkdownObject markdown);public abstract object Render(IMarkdownRenderContext context, MarkdownObject markdown);}public abstract class MarkdownRenderer<T> : MarkdownRendererwhere T : MarkdownObject{public override bool CanRender(MarkdownObject markdown){return markdown is T;}public override object Render(IMarkdownRenderContext context, MarkdownObject markdown){return Render(context, (T)markdown);}protected abstract object Render(IMarkdownRenderContext context, T markdown);}为什么返回object类型？这是由于Markdown里支持HTML内容，而markdig返回行内HTML内容时，会将一个元素拆成两个IarkdownRender 。一个是开头，例如<span>，一个是结尾，例如</span> 。
渲染Block和Inline
public RenderFragment RenderBlock(ContainerBlock containerBlock){return new RenderFragment(builder =>{int i = 0;foreach (var block in containerBlock){var obj = Render(block);if (obj is RenderFragment fragment)builder.AddContent(i, fragment);else if (obj is MarkupString markup)builder.AddContent(i, markup);else if (obj is HtmlElement html){if (html.IsEnd)builder.CloseComponent();else{builder.OpenElement(i, html.Tag);i++;if (html.Attributes != null){foreach (var attr in html.Attributes){if (attr.Value =https://www.huyubaike.com/biancheng/= null)builder.AddAttribute(i, attr.Key);elsebuilder.AddAttribute(i, attr.Key, attr.Value);i++;}}if (html.IsSelfClose)builder.CloseElement();}}elsebuilder.AddContent(i, obj);i++;}});}public RenderFragment RenderInline(ContainerInline containerInline){return new RenderFragment(content =>{var inline = containerInline.FirstChild;int i = 0;while (inline != null){var obj = Render(inline);if (obj is RenderFragment fragment)content.AddContent(i, fragment);else if (obj is MarkupString markup)content.AddContent(i, markup);else if (obj is HtmlElement html){if (html.IsEnd)content.CloseComponent();else{content.OpenElement(i, html.Tag);i++;if (html.Attributes != null){foreach (var attr in html.Attributes){if (attr.Value == null)content.AddAttribute(i, attr.Key);elsecontent.AddAttribute(i, attr.Key, attr.Value);i++;}}if (html.IsSelfClose)content.CloseElement();}}elsecontent.AddContent(i, obj);inline = inline.NextSibling;i++;}});}渲染整个Markdown文档
private void RenderMarkdown(RenderHandle renderHandle, MarkdownDocument document){var content = RenderBlock(document);renderHandle.Render(builder =>{builder.OpenComponent<LayoutView>(0);builder.AddAttribute(1, nameof(LayoutView.Layout), typeof(MainLayout));builder.AddAttribute(2, nameof(LayoutView.ChildContent), (RenderFragment)(child =>{child.OpenComponent<Index>(0);child.AddAttribute(1, "Content", content);child.CloseComponent();}));builder.CloseComponent();});}加载为了加快加载速度，按照官方文档，改为加载Brotli压缩后的文件并增加加载进度动画
