javascript - httpdispatcher 中的 setStatic 函数

Question

我正在用 node.js 构建一个服务器，但是我无法理解我在网上得到的这个例子中 httpdispatcher 中 setStatic 的功能。

            var http = require('http');
            var dispatcher = require('httpdispatcher');
            //Lets define a port we want to listen to
            const PORT=8080; 

            //We need a function which handles requests and send response
            function handleRequest(request, response){
                //response.end('It Works(Refereshed)!! Path Hit: ' + request.url);
                try{
                    console.log(request.url);
                    dispatcher.dispatch(request,response);

                }catch(err){console.log(err);}

            }

            //set all js/html/css as static during response
            dispatcher.setStatic('resources');

            dispatcher.onGet("/page1",function(req,res){
                res.writeHead(200,{'Content-Type':'text/plain'});
                res.end("Page one");
            });

            dispatcher.onPost("/page2",function(req,res){
                res.writeHead(200,{'Content-Type':'text/plain'});
                res.end("Get Post Data");
            });


            //Create a server
            var server = http.createServer(handleRequest);

            //Lets start our server
            server.listen(PORT, function(){
                //Callback triggered when server is successfully listening. Hurray!
                console.log("Server listening on: http://localhost:%s", PORT);
            });

但是当我运行这个文件并输入类似http://localhost:8080/resources/dwnl.png的url时然后我在终端中得到以下信息 [TypeError: Arguments to path.join must be strings] 浏览器上没有任何显示，但我在资源文件夹下有一个 dwnl.png

Answer 1

添加下一行

dispatcher.setStaticDirname(__dirname);

之前

dispatcher.setStatic('resources');

并尝试使用 http://localhost:8080/resources/dwnl.png
