`express` - sendfile wirft Fehler

Question

Ich versuche, eine express Anwendung zu entwickeln, in das ich Störung erhalte, während ich diesen Code verwenden:

//allways sending the index file 
    app.get('*', function(req, res){ 

    res.sendFile(path.join(__dirname + '/public/app/views/index.html')); 

    }) 

hier ist der vollständige Code:

var 

    express = require("express"), 
    config = require('./server.config'), 
    path = require('path'), 
    mongoose = require('mongoose'), 
    app  = express(); 

    //setting static 
    app.use(express.static(__dirname + '/public')); 

    //connect to data base; 
    mongoose.connect(config.database); 

    //allways sending the index file 
    app.get('*', function(req, res){ 

    res.sendFile(path.join(__dirname + '/public/app/views/index.html')); 

    }) 


    app.listen(config.port); 
    console.log('app started ' + config.port); 

Irgendjemand hilft mir, das zu beheben. auch, wie man den express in auf spät aktualisiert?

Answer 1

Ich glaube, Sie verwenden "Express" Version 3.x. Die "sendfile" -Funktion wurde in der Express-Version 3.x mit Kleinbuchstaben "f" definiert.

Sie können entweder die Expressversion aktualisieren (oder) den Methodennamen mit Kleinbuchstaben ändern, um dieses Problem zu beheben.

res.sendfile(path, [options], [fn]])
