使用URL Rewrite从iisnode提供静态文件 [英] Serving static files from iisnode with URL Rewrite

问题描述

我在web.config文件中使用了一个重写规则，用于在issnode下运行的节点应用程序指向我的server.js文件。 myapp / *指向server.js。

I am using a Rewrite rule in my web.config file for a node app running under issnode to point to my server.js file. myapp/* points to server.js.

    <rule name="myapp" enabled="true">
      <match url="myapp/*" />
      <action type="Rewrite" url="server.js" />
    </rule>

这一直很好www.mywebsite.com/myapp/会加载运行我的应用程序。我想要的是从网站的根目录进行重定向，以便www.mywebsite.com/运行我的应用程序。所以我改变了我的web.config文件

This has been working great www.mywebsite.com/myapp/ would load a run my app. What I wanted was to have a redirect from the root of the website so www.mywebsite.com/ would run my app. So I changed my web.config file

    <rule name="myapp" enabled="true">
      <match url="/*" />
      <action type="Rewrite" url="server.js" />
    </rule>

所以这是运行server.js并提供我的静态html文件，唯一的问题从我的html文件（css，js，图像等）引用任何外部文件只需为每个请求获得500。我用它来提供静态文件

So this is running the server.js and serving up a my a static html file, the only problem is referencing any external files from my html file (css, js, images etc) Just get 500s for every request. I am using this to serve static files

        var libpath = require('path');
        var _path = "."; <-- This seems to be the problem


        var uri = url.parse(req.url).pathname;
    var filename = libpath.join(_path, uri);
    fs.readFile(filename, "binary", function (err, file) {
            if (err) {
            res.writeHead(500, {
                "Content-Type": "text/plain"
            });
                 res.write(err + "\n");
                 res.end();
                return;
            }

         var type = mime.lookup(filename);
            res.writeHead(200, {
                "Content-Type": type
            });
         res.write(file, "binary");
         res.end();
        });

    break;

所以我的问题是如何指向我的节点app / server的root来提供静态文件。

So my question is how to point to root of my node app / server to serve up static files.

谢谢

推荐答案

在iisnode中提供静态内容的最佳方法是配置URL重写模块，使IIS静态文件处理程序处理静态内容而不是node.js的请求。让IIS提供静态内容比使用任何node.js机制提供这些文件具有很大的性能优势，因为内核级别优化了缓存，而且不必破解JavaScript代码。

The best way to serve static content in iisnode is to configure the URL rewriting module such that the IIS static file handler handles requests for static content rather than node.js. Having IIS serve static content has a large performance benefit over serving these files using any node.js mechanisms due to kernel level optimizations around caching and just not having to break into JavaScript code.

对于实现此目的的样板文件web.config配置，请参阅 https://github.com/tjanczuk/iisnode/issues/160#issuecomment-5606547
