Sails 应用程序在不调用船长上传时崩溃

Question

如果我调用req.file('files') 而没有调用updload（例如因为我抛出验证错误），应用程序就会崩溃。

const files = req.file('files')
if (!files || files.length === 0) {
  throw "MISSING_ARGUMENTS"; // intentally fails here
}
file.upload() // not reaching here

错误：

events.js:173
      throw er; // Unhandled 'error' event
      ^

我也面临同样的问题，就我而言，我检查了allParams()，这将防止应用崩溃。

const fileDetials = !('image' in req.allParams()) ? req.file('fieldName') : '';
