moajs / moa2 Goto Github PK

比如我git clone --depth=1 https://github.com/moajs/moa2.git moa2app ,
然后npm start就会报这种错：

Starting child process with 'node ./bin/www'
fs.js:856
  return binding.readdir(pathModule._makeLong(path));
                 ^

Error: ENOENT: no such file or directory, scandir '/Users/z/Projects/Node/moa2app/middlewares'
    at Error (native)
    at Object.fs.readdirSync (fs.js:856:18)

然后debug下mound-middlewares源码

var fs = require('fs')
var requireDirectory = require('require-directory')
var debug = require('debug')('mount-middlewares')

function m (dir) {
  var a = dir.split('app') //竟然是用split的。。

  if (a.length > 1) {
    a.pop()
    a.join('app')
  }else {
    if(fs.existsSync(dir + '/app/middlewares')){
      return requireDirectory(module, dir + "/app/middlewares") 
    }

    throw "mount-middlewares ERROR: " + dir + "里没有app目录"
  }
  var _dir = a[0] + "app/middlewares"
  debug(_dir)
  return requireDirectory(module, _dir)
}

module.exports = m

README还是得再改改……

根据步骤
$ git clone --depth=1 https://github.com/moajs/moa2.git <your-project-name> $ cd <your-project-name> $ npm install $ npm start
发现没有bin/www文件，整个项目跑不起来。

`require('../../config/log.js')

const jwt = require('jsonwebtoken')//用来创建和确认用户信息摘要

// 检查用户会话
module.exports = function (ctx, next) {
if (process.env.moas) {
ctx.api_user = {
_id : "55d8702d5472aa887b45f68c"
}
log('当前使用moas运行，不使用token即可访问！')
return next()
}

log('检查post的信息或者url查询参数或者头信息')

//检查post的信息或者url查询参数或者头信息
var token = req.body.token || req.query.token || req.headers['x-access-token']

// 解析 token
if (token) {
// 确认token
jwt.verify(token, 'app.get(superSecret)', function (err, decoded) {
if (err) {
return res.json({ success: false, message: 'token信息错误.' })
} else {
// 如果没问题就把解码后的信息保存到请求中，供后面的路由使用
ctx.api_user = decoded
dir(ctx.api_user)
return next()
}
})
} else {
// 如果没有token，则返回错误
ctx.status = 403
return ctx.body = {
success: false,
message: '没有提供token！'
}
}
}`

这里 req没有 声明，然后 我声明之后 就变成了
<-- POST /api/users xxx POST /api/users 500 9ms - TypeError: Cannot read property 'token' of undefined at module.exports (/Users/thomaslau/WebstormProjects/moa2/app/middlewares/check_api_token.js:25:23)

非常简单又实用的功能
