Node.js 检查路径是文件还是目录 [英] Node.js check if path is file or directory

问题描述

我似乎无法获得任何解释如何执行此操作的搜索结果.

我想要做的就是知道给定的路径是文件还是目录(文件夹).

解决方案

下面应该告诉你.来自文档:

fs.lstatSync(path_string).isDirectory()

<块引用>

从 fs.stat() 和 fs.lstat() 返回的对象属于这种类型.

stats.isFile()stats.isDirectory()stats.isBlockDevice()stats.isCharacterDevice()stats.isSymbolicLink()//(仅对 fs.lstat() 有效)stats.isFIFO()stats.isSocket()

注意:

上述解决方案将throw一个Error如果；例如，file 或 directory 不存在.

如果您想要 true 或 false 方法，请尝试 fs.existsSync(dirPath) &&fs.lstatSync(dirPath).isDirectory(); 正如约瑟夫在下面的评论中提到的那样.

I can't seem to get any search results that explain how to do this.

All I want to do is be able to know if a given path is a file or a directory (folder).

解决方案

The following should tell you. From the docs:

fs.lstatSync(path_string).isDirectory() 

Objects returned from fs.stat() and fs.lstat() are of this type.

stats.isFile()
stats.isDirectory()
stats.isBlockDevice()
stats.isCharacterDevice()
stats.isSymbolicLink() // (only valid with fs.lstat())
stats.isFIFO()
stats.isSocket()

NOTE:

The above solution will throw an Error if; for ex, the file or directory doesn't exist.

If you want a true or false approach, try fs.existsSync(dirPath) && fs.lstatSync(dirPath).isDirectory(); as mentioned by Joseph in the comments below.
