我在一个示例REST中的POST请求有一个小问题。
我只有四条路由的四种回调方法:
app.get '/tasks', task.getAll
app.get '/tasks/done', task.getDone
app.get '/tasks/notdone', task.withoutDone
app.post '/tasks', task.newTask以及:
模型=需要“./model/model s.js”
exports.getAll = (req, res, next) ->
models.Task.find {}, 'title description, done', (err, tasks) ->
if err then err
res.send tasks
do next
exports.getDone = (req, res, next) ->
models.Task.find {done: true}, (err, tasks) ->
if err then err
res.send tasks
do next
exports.withoutDone = (req, res, next) ->
models.Task.find {done: false}, (err, tasks) ->
if err then err
res.send tasks
do next
exports.newTask = (req, res, next) ->
if req.params.title is undefined
return next new restify.InvalidArgumentError 'Title is needed'
taskData =
title: req.params.title
description: req.params.description
done: req.params.done
task = new Task(taskData)
task.save (err, data) ->
if err
return next new restify.InvalidArgumentError(JSON.stringify(error.errors))
else
res.json(data)
res.send 201, task因此,您可以在唯一的gist中找到代码这里。
当我奔跑时的痕迹
curl -i -X POST -d '{"title": "hello world", description: "lorem ipsum dolor amet", "done": true}' http://localhost:8080/tasks返回是我的一个500内部的头在回应:

在错误处理方面,Restify有类似的设计。它采用JSON格式,并伴有HTTP 500错误,吞食未察觉的异常并将它们发送回浏览器,而不是在控制台上打印它们。
消息"restify未定义“通常意味着您忘记在脚本中的某个地方调用var restify = require('restify');。
您还可以使用以下代码段在控制台精确定位错误的位置:
server.on('uncaughtException', function (req, res, route, err) {
console.log('uncaughtException', err.stack);
