由于网页优化不能很好地配合动态dontent,我决定不使用它。
相反,我为 LESS 制作了 ASP MVC ActionResult,并参考了它。
<link rel="stylesheet" type="text/css" href="@Url.Action("Styles", "Theme")">
我的 ASP MVC 控制器如下所示:
public class ThemeController : Controller
{
public ActionResult Styles()
{
var parameters = new Dictionary<string, string>
{
{"themeColor1", "Get theme color 1 here"},
{"themeColor2", "Get theme color 2 here"}
};
var themeLessFilePath = Server.MapPath("~/Content/less/theme.less");
using (var stream = System.IO.File.OpenRead(themeLessFilePath))
{
return new DotLessResult(stream, parameters, true);
}
}
}
像这样的 LESS ActionResult:
public class DotLessResult : ActionResult
{
public IDictionary<string, string> Parameters { get; set; }
public string Less { get; set; }
public bool Minify { get; set; }
public DotLessResult(string less, IDictionary<string, string> parameters = null, bool minify = false)
{
Less = less;
Parameters = parameters ?? new Dictionary<string, string>();
Minify = minify;
}
public DotLessResult(Stream stream, IDictionary<string, string> parameters = null, bool minify = false)
: this(new StreamReader(stream).ReadToEnd(), parameters, minify) { }
public override void ExecuteResult(ControllerContext context)
{
var output = Less;
//TODO: Not the way to do this!
foreach (var key in Parameters.Keys)
{
output = Regex.Replace(output, @"@" + key + @":\s*\S+;", "@" + key + ":" + Parameters[key] + ";");
}
var lessEngine = dotless.Core.LessWeb.GetEngine(new DotlessConfiguration { MinifyOutput = Minify, MapPathsToWeb = true, Web = true, CacheEnabled = false});
var css = lessEngine.TransformToCss(output, (string)null);
context.HttpContext.Response.ContentType = "text/css";
using (var writer = new StreamWriter(context.HttpContext.Response.OutputStream, Encoding.UTF8))
{
writer.Write(css);
writer.Flush();
}
}
}
它不是最好的解决方案,但它适用于我的机器 TM。
不要忘记实现某种输出缓存,因为它很可能会受到很多影响,并且不会经常更改。
