Angularjs 错误：404错误请求Mongo、Express、Angular、Node

我有一个无法解决的问题，我的应用程序返回错误400错误请求，我不能做任何post，但使用邮递员它正常工作，我可以做get、post、put、delete，但在我的应用程序中无法做post，我做了多次并重拨了代码，问题没有得到纠正，我需要解决这个问题

我的控制器

angular.module('primeiraApp').controller('CarCycleCtrl', [
  '$scope',
  '$http',
  '$location',
  'msgs',
  'tabs',
  'consts',

我的后端

const _ = require('lodash')
const CarCycle = require('./carCycle')

CarCycle.methods(['get', 'post', 'put', 'delete'])
CarCycle.updateOptions({new: true, runValidators: true})

CarCycle.after('post', sendErrorsOrNext).after('put', sendErrorsOrNext)

function sendErrorsOrNext(err, req, res, next) {
  const bundle = res.locals.bundle
  if(bundle.errors) {
    var errors = parseErrors(bundle.errors)
    res.status(500).json({errors})
  } else {
    next()
  }
}

function parseErrors(nodeRestfulErrors) {
  const errors = []
  _.forIn(nodeRestfulErrors, error => errors.push(error.message))
  return errors
}

CarCycle.route('count', function(req, res, next) {
  CarCycle.count(function(error, value) {
    if(error) {
      res.status(500).json({errors: [error]})
    } else {
      res.json({value})
    }
  })
})

module.exports = CarCycle
