Question

NodeJS中有没有类似jQuery validate一样的中间件插件

Answer 1

nstallation
npm install express-validator

Usage
var util = require('util'),
express = require('express'),
expressValidator = require('express-validator'),
app = express.createServer();app.use(express.bodyParser());app.use(expressValidator([options]));app.post('/:urlparam', function(req, res) {

// checkBody only checks req.body; none of the other req parameters req.checkBody('postparam', 'Invalid postparam').notEmpty().isInt();
req.assert('getparam', 'Invalid getparam').isInt();
req.assert('urlparam', 'Invalid urlparam').isAlpha();

req.sanitize('postparam').toBoolean();

var errors = req.validationErrors();
if (errors) {
res.send('There have been validation errors: ' + util.inspect(errors), 400);
return;
}
res.json({
urlparam: req.param('urlparam'),
getparam: req.param('getparam'),
postparam: req.param('postparam')
});});app.listen(8888);
