Question

我正在开发一个Node.js应用程序，使用http和httpdispatcher来处理Web服务器请求。我有以下代码：

var app = require('http').createServer(handler),
    sys = require('util'),
    exec = require('child_process').exec,
    io = require('socket.io').listen(app),
    fs = require('fs'),
    dispatcher = require('httpdispatcher');

app.listen(61337);

dispatcher.setStatic('assets');

function puts(error, stdout, stderr) { sys.puts(stdout) }

function handler (request, response) {
    dispatcher.dispatch(request, response);
}

dispatcher.onGet("/", function(req, res) {
    res.writeHead(200, {'Content-Type': 'text/html'});
        fs.readFile('./assets/index.html', 'utf8', function (err,data) {
            res.end(data);
        });
});

dispatcher.onGet("/api/update", function(req, res) {
    exec("sh /path/to/update.sh &", puts);

  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('1');
});

io.sockets.on('connection', function (socket) {
    /** Socket.io coming soon */
});

我收到以下错误。

path.js:360
    throw new TypeError('Arguments to path.join must be strings');

TypeError: Arguments to path.join must be strings

Server.handler (***/app-server.js:19:13)函数中的dispatcher.dispatch(request, response);行是handler ..所以我不确定为什么它不发送字符串？

我从使用httpdispatcher转到express

以下是我的工作示例：

var express = require('express'),
    app = express(),
    http = require('http').createServer(app).listen(61337),
    sys = require('util'),
    exec = require('child_process').exec,
    io = require('socket.io')(http),
    fs = require('fs');

app.use('/assets', express.static('assets'));

function puts(error, stdout, stderr) { sys.puts(stdout) }

app.get("/", function(req, res) {
    res.writeHead(200, {'Content-Type': 'text/html'});
        fs.readFile('./assets/index.html', 'utf8', function (err,data) {
            res.end(data);
        });
});

app.get("/api/update", function(req, res) {
    exec("sh /path/to/update.sh &", puts);

  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('1');
});

io.sockets.on('connection', function (socket) {

});
