使用Sails.js上载可选文件

有没有可能让Sails接受可选的文件上载，而不在请求几秒钟后吐出以下堆栈跟踪

Upstream (file upload: `image`) emitted an error: { Error: EMAXBUFFER: An upstream (`NOOP_image`) timed out before it was plugged into a receiver. It was still unused after waiting 4500ms. You can configure this timeout by changing the `maxTimeToBuffer` option.

Note that this error might be occurring due to an earlier file upload that is finally timing out after an unrelated server error.

如果HTTP请求中没有上传，那么uploadedFiles是一个空数组，其余的操作代码运行时没有问题，但我不希望日志中充满这种垃圾。

事实证明，这很简单，只需从npm中引入模块，并用类似的内容替换原始问题中的Promise wrapped cruft

let uploadedFiles=wait sails.upload（inputs.image，{/*自定义适配器配置*/}）；

看起来工作正常，但如果请求中未提供任何内容，则不会记录上载未被及时拦截的警告

通过定量配给示例应用程序得出了这个解决方案。
