我收到错误req.checkBody不是我认为已包含express-validator和body-parser的函数。
这是我的代码
var express = require('express');
var bodyParser = require('body-parser');
var app = express();
var expressValidator = require('express-validator');
app.use(bodyParser.urlencoded({ extended: true }));
app.get('/',function(req,res){
res.sendFile(__dirname +'/index.html')
});
app.post('/',function(req,res){
req.checkBody("name", "Invalid company").notEmpty();
var errors = req.validationErrors();
if (errors) {
res.status(400).send({ "message": "Missing parameter" });
// res.send('There have been validation errors: ' + util.inspect(errors), 400);
return;
}
var company = new companySchema(req.body);
company.save(function(err) {
if (err) {
if (err.code === 11000) {
return res.status(409).send({ "message": "Company already exist!" });
}
return res.status(400).send({ "message": "Server Error!", "err": err });
}
return res.status(200).send({ "message": "New company has added!" });
});
});
app.listen('3000');
console.log('listening on 3000!')
包含编辑部分的index.html以供参考
index.html
<html>
<body>
<form method = "post" action="http://localhost:3000">
<label for="fname">Company name</label>
<input type="text" id="fname" name="name">
<input type="submit" value="Submit">
</form>
</body>
</html>
我得到的错误是
TypeError:req.checkBody不是函数
最佳答案
var express = require('express');
var bodyParser = require('body-parser');
var app = express();
var expressValidator = require('express-validator');
app.use(bodyParser.urlencoded({ extended: true }));
app.use(expressValidator()); //this line to be addded
app.get('/',function(req,res){
res.sendFile(__dirname +'/index.html')
});
app.post('/',function(req,res){
req.checkBody("name", "Invalid company").notEmpty();
var errors = req.validationErrors();
if (errors) {
res.status(400).send({ "message": "Missing parameter" });
// res.send('There have been validation errors: ' + util.inspect(errors), 400);
return;
}
var company = new companySchema(req.body);
company.save(function(err) {
if (err) {
if (err.code === 11000) {
return res.status(409).send({ "message": "Company already exist!" });
}
return res.status(400).send({ "message": "Server Error!", "err": err });
}
return res.status(200).send({ "message": "New company has added!" });
});
});
