我有在node.js中登记的形式与我的帖子麻烦每一个形式张贴在体内的请求时,有信息,但身体是空的。我是新来的节点,并表示因此它可能是小东西,但我不能为我的生命数字出来。
这是我在EJS形式:
<form class="form-signin" method="post" action="/users/register">
<div class="form-group">
<label class="sr-only" for="email">Email address</label>
<input type="email" class="form-control" id="email" placeholder="Enter Email" autocomplete="off">
</div>
<div class="form-group">
<label class="sr-only" for="password">Password</label>
<input type="password" class="form-control" id="password" placeholder="Enter Password">
</div>
<div class="form-group">
<label class="sr-only" for="confirmPassword">Confirm Password</label>
<input type="password" class="form-control" id="confirmPassword" placeholder="Re-enter Password">
</div>
<button class="btn btn-dark mt-3" type="submit">Submit</button>
</form>
这里是用户路由器中我的路由器代码:
router.post('/register', function(request, response, next) {
console.log(request);
console.log(request.body)
response.render('register', { 'title': 'Register' });
});
下面是在控制台上相关的输出:
console.log(request); output shortened this is just the tail.

app.js代码:
var createError = require('http-errors');
var express = require('express');
var path = require('path');
var cookieParser = require('cookie-parser');
var logger = require('morgan');
var bodyParser = require('body-parser');
var indexRouter = require('./routes/index');
var usersRouter = require('./routes/users');
var app = express();
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');
app.use(logger('dev'));
app.use(express.json());
app.use(express.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());
app.use('/', indexRouter);
app.use('/users', usersRouter);
app.use(function(request, response, next) {
next(createError(404));
});
app.use(function(error, request, response, next) {
response.locals.message = error.message;
response.locals.error = request.app.get('env') === 'development' ? error : {};
response.status(error.status || 500);
response.render('error');
});
module.exports = app;
事情我已经尝试:
我在这一点上,它与EJS形式的问题,因为在请求体对象始终是空的相当肯定。
在形式<input>
元件必须定义一个name
属性,而不仅仅是id
。
对方的回答中指出你错过了什么,我更新了.ejs代码向您展示发布HTML表单的正确方法:
<form class="form-signin" method="post" action="/users/register">
<div class="form-group">
<label class="sr-only" for="email">Email address</label>
<input type="email" name="email" class="form-control" id="email" placeholder="Enter Email" autocomplete="off">
</div>
<div class="form-group">
<label class="sr-only" for="password">Password</label>
<input type="password" name="password" class="form-control" id="password" placeholder="Enter Password">
</div>
<div class="form-group">
<label class="sr-only" for="confirmPassword">Confirm Password</label>
<input type="password" name="confirmPassword" class="form-control" id="confirmPassword" placeholder="Re-enter Password">
</div>
<button class="btn btn-dark mt-3" type="submit">Submit</button>
</form>
您可以做到以上或处理与使用Javascript / jQuery的提交,如果你提交一个更复杂的形式或需要在域某种验证。
看到这个答案:Submit a form using jQuery
另一个常见的错误使用快递时,请确保您使用boyParser i.e
const router = express();
const bodyParser = require('body-parser');
router.use(bodyParser.json())
.use(bodyParser.urlencoded({
extended: true
}));
