我是Massive的新手,但我真的很喜欢它。在使用express.Router()
并进行非常简单的数据库调用时:
router.get('/:id', function(req, res, next) {
db.accounts.find(req.params.id, function(err, results) {...});
我收到了一个错误:
错误:参数0(条件)应该是Object类型,但它是类型 值为2的字符串。 在Args(C:\ Users \ JMichelson \ WebstormProjects \ Proximityv6 \ node_modules \ args-js \ Args.js:399:10) at Object.exports.forArgs(C:\ Users \ JMichelson \ WebstormProjects \ Proximityv6 \ node_modules \ massive \ lib \ arg_types.js:7 7:10)......
通过简单的演员解决了这个问题:
router.get('/:id', function(req, res, next) {
db.accounts.find(Number(req.params.id), function(err, results) {...});
但我发现这个转换要求很奇怪,因为JavaScript应该根据需要自动转换。
我这样做是否正确?
答案 0 :(得分:1)
I believe that find wants a number and the params come in as a string so the args parser gets confused. You can use int.parse
here or do what you're doing. Massive is a bit opinionated in this regard: you can use string keys if you want but you'll have to be specific with `{id:"my string"}.
