Sails.js 使用自定义Skipper正文分析器配置时出错

我使用的是sails版本0.10.5。我在

http.js

中设置了bodyParser：

bodyParser: require('skipper')({
  limit: 52428800
})

在启动服务器时，我不断遇到以下错误：

error: Encountered an error when trying to use configured bodyParser.
error: Usually, this means that it was installed incorrectly.
error: A custom bodyParser can be configured without calling the wrapper function- e.g.:
```
bodyParser: require("connect-busboy")
```
error: Alternatively, if you need to provide options:
```
bodyParser: {
fn: require("connect-busboy"),
options: {/* ... */}
}
```

之后就没有错误了。我做错了什么？我试着按照错误的说明操作，但是使用skipper，我无法将文件上传到S3，上传的大小不能超过几mb。我试过这个，但不起作用：

bodyParser: {
fn: require("skipper"),
options: {limit: 52428800}
}

这与上面的消息一致。

由于Sails<0.12中默认的

bodyParser

设置中存在错误，配置中间件的正常方法将无法工作。最简单的解决方案是简单地用另一个自定义中间件名称替换中间件顺序中的

bodyParser

，并对其进行配置，例如：

module.exports.http = {

  middleware: {

    // The order in which middleware should be run for HTTP request.
    // (the Sails router is invoked by the "router" middleware below.)
    order: [
      'startRequestTimer',
      'cookieParser',
      'session',
      // 'bodyParser', // <-- don't add the "bodyParser" middleware to the stack
      'skipper',   // <-- instead use this "custom" middleware
      'handleBodyParserError',
      'compress',
      'methodOverride',
      'poweredBy',
      '$custom',
      'router',
      'www',
      'favicon',
      '404',
      '500'
    ],

    // Configure Skipper
    skipper: require('skipper')({
      limit: 52428800
    })

  }
}

module.exports.http={
中间件：{
//为HTTP请求运行中间件的顺序。
//（下面的“路由器”中间件调用Sails路由器。）
订单：[
“startRequestTimer”，
“cookieParser”，
“会议”，
//“bodyParser”，//由于Sails<0.12中默认的
