nightmare-webrequest-addon

The webRequest API set allows to intercept and modify contents of a request at various stages of its lifetime. (from https://github.com/electron/electron/blob/master/docs/api/session.md#seswebrequest)

This is the wrapper of Electron API session.webRequest.

Install

npm install --save nightmare-webrequest-addon

Usage

nightmare.onBeforeRequest([filter, ]listener)

• details Object
  • id Integer
  • url String

  • uploadData Array (optional)
• callback Function

The uploadData is an array of data objects:

  • redirectURL String (optional) - The original request is prevented from being sent or completed, and is instead redirected to the given URL.

Note: listener is Electron-side context, cannot access any variable/function outside of listener

If you want to use details Object in the nodeJS-side, use nightmare.on('onBeforeRequest', callback)

The callback has to be called with an details object:

• details Object
  • id Integer
  • url String
