我经常抛出以下错误:
unsigned long
下面是我的完整Error handling invalid query params:
Error: expected 422 "Unprocessable Entity", got 200 "OK"
。
/app.js
我怎样才能更好地处理带有node.js / express的我的无效查询参数,或许可以停止抛出此错误?
我已经安装了express-validation - 并希望这条路线能够解决错误;但我不确定如何从给出的例子中实施。
'use strict'
var path = require('path');
var meal = require('./meals.js');
var express = require('express');
var router = express.Router();
var app = express();
module.exports = function(app) {
app.get('/allMeals', meal.getAllMeals, END);
app.get('/meals/:id', meal.getMealinfo, END, function(req, res, next) {
meal.findById(req.params.id).exec()
.then(function(xxx) {
if (meal == null) return next(); // Not found
return res.send('Found meal '+request.params.id);
})
.then(null, function(err) {
return next(err);
});
});
app.get('/meals/:id/options',meal.getHealthymeals, END);
function END(req,res){
res.end();
}
res.status(404).send({
message: 'Router not found.'
});
});
};
