Sails Body Parser配置

标签: node.js heroku sails.js sails-skipper

我在Heroku上托管了一个应用程序,它发送一个巨大的数量的JSON。我最初得到一个bodyParser - 请求实体太大的错误(HTTP 400)。谷歌搜索,我遇到了一些stackoverflow / github问题链接

Sails.js bodyParser - request entity too large on version 0.10.5) (https://github.com/balderdashy/skipper/issues/144

我尝试更新我的http.js.现在我的身体解析器看起来像这样:

bodyParser: {
  fn: require('skipper'),
  options:{
    limit: '10mb'
  }
}

这解决了400错误,但现在我收到了Heroku H13错误:

2016-08-11T14:02:08.861774+00:00 heroku[router]: at=error code=H13 desc="Connection closed without response"

此时,我有点难过。我查看了Heroku关于H13错误的文档

https://devcenter.heroku.com/articles/error-codes#h13-connection-closed-without-response),

但我不确定是否

  1. 我需要使用Heroku配置更多(我甚至可以这样做)或
  2. 使用Sails bodyParser配置或
  3. 执行更多操作
  4. 两者的组合
  5. 我目前正在使用Sails版本0.11.2。

    我注意到一个人在中间件块之外有他们的bodyParser配置。我也试过把我的外面移动到外面,它似乎修复了我收到的400和503 H13 Heroku问题(我慢慢地试图远离问题)。我的新问题是,为什么以下工作,特别是因为bodyParser注释块是里面中间件块?

您可以将中间件放在中间件对象的内部和外部。正如医生所说的那样,你把中间件放在那些没有跟随app.use(中间件)'惯例。

由于您的bodysarser中间件返回require('skipper')({limit:'10mb'})而不是require('skipper'),这是非常不同的,因此它不会遵循app.use(中间件)'惯例,应该像你一样放在http模块的根目录外面。
