javascript - req.body 未填充表单数据

Question

以下文件是我尝试向我的 nodejs (express) 服务器提交 POST 请求。 req.body 不会从我的表单中填充任何类型的数据。我做了很多搜索，发现针对这个特定问题的许多解决方案包括在我的路线之前移动 bodyparser 并确保在表单字段中包含一个名称。
任何帮助表示赞赏。

app.js

[variables]
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(validator({errorFormatter: -----}));
[other middleware]
require('./passport')(app, passport);
require('./routes')(app, passport);
[start server]

index.jade

block content
h1= title
p Please register below
.error-messages
    ul.errors
        if errors
            each error, i in errors
                li.alert.alert-danger #{error.msg}
form(method='post', action='/signup', enctype='multipart/form-data')
    .form-group
        label Name
        input.form-control(type='text', name='name', placeholder='Enter name')
    .form-group
        label Email
        input.form-control(type='email', name='email', placeholder='Enter email')
    .form-group
        label Username
        input.form-control(type='text', name='username', placeholder='Enter a username')
    .form-group
        label Password
        input.form-control(type='password', name='password')
    .form-group
        label Confirm Password
        input.form-control(type='password', name='passwordConfirm')
    input.btn.btn-primary.pull-right(type='submit', name='submit', value='Sign Up')

index.js(从 app.post('/signup', ...) 调用

var name = req.body.name,
    email = req.body.email,
    username = req.body.username,
    password = req.body.password,
    passwordConfirm = req.body.passwordConfirm;

name = 'meg';

console.log('name: ' + req.body.name);
console.log('email: ' + req.body.email);
console.log('name2: ' + name);
console.log(req.body);
console.log(req.headers);
console.log(req.is('json'));

控制台日志

Answer 1

您为表单使用了错误的 enctype，express 默认不支持 multipart(用于文件上传)，您需要使用 x-www-form-urlencoded。

form(method='post', action='/signup', enctype='application/x-www-form-urlencoded')
