POST请求无法在restify中工作,导致500内部服务器错误

我在示例RESTAPI中的POST请求中遇到了一个小问题。

我只有四个用于四个路由的回调方法:

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'/models/models.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

所以,你可以找到代码 here 在一个独特的要点。

我跑步时的痕迹

curl -i -X POST -d '{"title": "hello world", description: "lorem ipsum dolor amet", "done": true}' http://localhost:8080/tasks

在回答中,我得到了500个内部头:
