最近我开始使用express.js中的nodejs web框架。我正在制作一个简单的表格,将数据发送到快速路线。 我有一个users.js路由文件,里面有一个注册路由。
我的user.js路由文件
router.post('/register', function(req, res, next) {
var name = req.body.name;
var email = req.body.email;
var username = req.body.username;
var password = req.body.password;
var passwordConfirm = req.body.passwordConfirm;
console.log(name);
我的玉文件是哪个表格
form(method='post',action='/users/register',enctype='multipart/form-data')
.form-group
label Name
input.form-control(name='name',type='text',placeholder='Enter Name')
and go on ...
console.log retunrs undefiend。
我的app.js。我使用快速生成器生成项目,你可以看到我有multer和bodyparser
var bodyParser = require('body-parser');
var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var expressValidator = require('express-validator');
var cookieParser = require('cookie-parser');
var session = require('express-session');
var passport = require('passport');
var LocalStrategy = require('passport-local').Strategy;
var multer = require('multer');
var flash = require('connect-flash');
var mongo = require('mongodb');
var mongoose = require('mongoose');
var db = mongoose.connection;
var routes = require('./routes/index');
var users = require('./routes/users');
var app = express();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
// multer config inja
var upload = multer({ dest: './uploads' });
// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
// // handle express session
app.use(session({
secret: 'secret', //encryption key
saveUninitialized:true,
resave:true
}));
// // Passport
app.use(passport.initialize());
app.use(passport.session());
app.use(expressValidator({
errorFormatter: function(param, msg, value) {
var namespace = param.split('.')
, root = namespace.shift()
, formParam = root;
while(namespace.length) {
formParam += '[' + namespace.shift() + ']';
}
return {
param : formParam,
msg : msg,
value : value
};
}
}));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
// flash messaging via connect-flash
app.use(flash());
app.use(function (req, res, next) {
res.locals.messages = require('express-messages')(req, res);
next();
});
app.use('/', routes);
app.use('/users', users);
// catch 404 and forward to error handler
app.use(function(req, res, next) {
var err = new Error('Not Found');
err.status = 404;
next(err);
});
// error handlers
// development error handler
// will print stacktrace
if (app.get('env') === 'development') {
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: err
});
});
}
// production error handler
// no stacktraces leaked to user
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: {}
});
});
module.exports = app;

在点击/register
路由之前,您必须配置一个快速中间件来解析HTTP请求的正文。
multipart/form-data
enctype 这种类型通常用于文件上传。像Multer这样的库对这个用例很有帮助。
我没有在您的示例中看到要上传的文件。所以你应该考虑使用一个简单的enctype,比如application / x-www-form-urlencoded enctype(默认)(见下文)。
如果您仍想在没有文件上传的情况下使用表单数据enctype,则可以使用express-busboy之类的库(构建于busboy之上)。
var app = express();
var bb = require('express-busboy');
bb.extend(app);
// ...
router.post('/register', function(req, res, next) {
// req.body contains your fields.
// ...
application/x-www-form-urlencoded
enctype(默认)如果您将表单配置为使用application/x-www-form-urlencoded
enctype,则在您的路线中处理起来会更容易一些。
body-parser
也可以用作中间件:https://github.com/expressjs/body-parser#bodyparserurlencodedoptions
var app = express();
// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded());
// ...
router.post('/register', function(req, res, next) {
// ...
```
