请求。正文未填充表单数据

Question

以下文件是我试图向nodejs（Express）服务器提交POST请求的过程。req.body不会从我的表单中填充任何类型的数据。我已经做了很多搜索，发现许多解决这个特殊问题的方法包括在我的路线之前移动身体解析器，并确保在表单字段中包含名称。

应用程序。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]

.error-messages
    ul.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')

指数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'));

Answer 1

您正在发送一个多部分/表单数据请求，但未使用与多部分/表单数据兼容的正文解析中间件。一些处理这种格式的中间件模块示例有multer和multiparty/强大的。

Answer 2

您对表单使用了错误的enctype，Express默认不支持多部分（用于文件上传），您需要使用x-wow-form-urlencoded。

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