Question

尝试使用Node.js显示html页面时出现一个错误。我在下面提供错误。

TypeError: path must be absolute or specify root to res.sendFile
   at ServerResponse.sendFile (/opt/lampp/htdocs/heroku/FGDP/node_modules/express/lib/response.js:404:11)

   at Immediate.<anonymous> (/opt/lampp/htdocs/heroku/FGDP/node_modules/express-session/index.js:473:7)

我在下面提供我的代码。

var express=require('express');
var morgan = require('morgan');
var http=require('http');
var bodyParser= require('body-parser');
var methodOverride = require('method-override');
var mongo = require('mongojs');
var session = require('express-session');
var multer  = require('multer')
var app=module.exports=express();
var server=http.Server(app);
var port=8989;
var admin=require('./route/route.js');
var api=require('./api/api.js');
app.use(express.static(__dirname + '/public'));     // set the static files location /public/img will be /img for users
app.use(morgan('dev'));                     // log every request to the console
app.use(bodyParser.urlencoded({ extended: false }))    // parse application/x-www-form-urlencoded
app.use(bodyParser.json())    // parse application/json
app.use(methodOverride());                  // simulate DELETE and PUT
app.use(session({secret: 'FGDPlexel',resave: true,saveUninitialized: true}));
app.get('/',function(req,res){
    res.sendFile(__dirname + '/index.html');
})
app.get('/api/users/reset',function(req,res){
    res.sendFile('views/reset.html');
})
server.listen(port);

当我输入网址http://localhost:8989/api/users/reset?id=5981b48654d471000459208e时，我收到了上述错误。我的文件夹结构如下所示。

fgdp(root folder)
 -> public
     ->views
     ->controller

 server.js

我的HTML页面位于views文件夹中。

Answer 1

您没有指定绝对路径，请解决它。将您的路线请求修改为

app.get('/',function(req,res){
    res.sendFile(path.join(__dirname, '/public/views', 'index.html'));
});
app.get('/api/users/reset',function(req,res){
    res.sendFile(path.join(__dirname, '/public/views', 'reset.html'));
})

Answer 2

控制台日志__dirname + '/index.html'以检查index.hmtl的路径是否正确。

其次，res.sendFile('views/reset.html');这不会起作用。它清楚地说使用绝对路径。 views/reset.html是一条相对路径。使用path.resolve和__dirname来获取绝对路径。

使用Node.js重定向到页面时获取类型错误
