如何将IHttpContextAccessor传递给DotLiquid的自定义标记

// 自定义标记类
public class MyCustomTag : Tag
{
    private readonly IHttpContextAccessor _httpContextAccessor;

    public MyCustomTag(string tagName, string markup, List<string> tokens)
        : base(tagName, markup, tokens)
    {
        // 构造函数接受IHttpContextAccessor参数
        _httpContextAccessor = (IHttpContextAccessor)Context["http_context_accessor"];
    }

    public override void Render(Context context, TextWriter result)
    {
        // 使用IHttpContextAccessor访问HTTP上下文信息
        var requestUrl = _httpContextAccessor.HttpContext.Request.Path;

        // 执行自定义逻辑并输出结果
        result.Write($"Request URL: {requestUrl}");
    }
}

// 使用DotLiquid渲染模板
public class TemplateRenderer
{
    private readonly IHttpContextAccessor _httpContextAccessor;

    public TemplateRenderer(IHttpContextAccessor httpContextAccessor)
    {
        _httpContextAccessor = httpContextAccessor;
    }

    public string RenderTemplate(string templateContent)
    {
        // 创建DotLiquid的Template对象
        var template = Template.Parse(templateContent);

        // 注册自定义标记类
        template.RegisterTag<MyCustomTag>("my_custom_tag");

        // 将IHttpContextAccessor实例传递给自定义标记类
        template.Context["http_context_accessor"] = _httpContextAccessor;

        // 渲染模板并返回结果
        return template.Render();
    }
}
