方法​

¥Methods

webUtils 模块有以下方法：

¥The webUtils module has the following methods:

webUtils.getPathForFile(file)​

  • file 文件 - 一个 Web 文件 对象。

    ¥file File - A web File object.

返回 string - 该 File 对象指向的文件系统路径。如果传入的对象不是 File 对象，则会引发异常。如果传入的 File 对象是在 JS 中构造的并且不受磁盘上的文件支持，则返回空字符串。

¥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.

此方法取代了之前使用 path 属性对 File 对象的增强。下面包含一个示例。

¥This method superseded the previous augmentation to the File object with the path property. An example is included below.

// Before
const oldPath = document.querySelector('input').files[0].path

// After
const { webUtils } = require('electron')
const newPath = webUtils.getPathForFile(document.querySelector('input').files[0])
