webUtils
A utility layer to interact with Web API objects (Files, Blobs, etc.)
Process: Renderer
info
If you want to call this API from a renderer process with context isolation enabled,
place the API call in your preload script and
expose it using the
contextBridge API.
Métodos
The webUtils module has the following methods:
webUtils.getPathForFile(file)
fileFile - A web File object.
Returns string - The file system path that this File object points to. In the case where the object passed in is not a File object an exception is thrown. In the case where the File object passed in was constructed in JS and is not backed by a file on disk an empty string is returned.
This method superseded the previous augmentation to the File object with the path property. Un ejemplo se incluye a continuación.
// Before (renderer)
const oldPath =document.querySelector('input[type=file]').files[0].path
// After
// Renderer:
const file =document.querySelector('input[type=file]').files[0]
electronApi.doSomethingWithFile(file)
// Preload script:
const{ contextBridge, webUtils }=require('electron')
contextBridge.exposeInMainWorld('electronApi',{
doSomethingWithFile(file){
const path = webUtils.getPathForFile(file)
// Do something with the path, e.g., send it over IPC to the main process.
// It's best not to expose the full file path to the web content if possible.
}
