这是我第一次在这里发帖,如果有任何错误,请告诉我。 我对node和express都很陌生。我创建了一个简单的注册表格,但当我按下“注册”(提交)按钮时,req.body.name却显示为“未定义”。 以下是我的app.js、users.js和register.jade文件。
register.jade
extends layout
block content
h1 Register
p Please Register using a form below
ul.errors
if errors
each error , i in errors
li.alert.alert-danger #{error.msg}
form(method='post',action='/users/register',enctype='multipart/form-data')
.form-group
label Name
input.form-control(name='name',type='text',placeholder='Enter Your Lucky Name')
.form-group
label Email
input.form-control(name='email',type='email',placeholder='Enter Your Email')
.form-group
label Password
input.form-control(name='password',type='password',placeholder='Enter Password')
.form-group
label Confirm Password
input.form-control(name='password2',type='password',placeholder='Enter Password')
.form-group
label Profie Image
input.form-control(name='profileimage',type='file')
input.btn.btn-default(name='submit',type='submit',value='Register')

users.js
中,你重新初始化了express路由,使用var router = express.Router();
这个语句覆盖了你在app.js中所有的app.use
语句。尝试在你的users.js
中添加一些app.use
语句,但将它们改为router.use
