path.basename(path[, suffix])

• path <string>

• suffix <string> 要删除的可选后缀

  ¥suffix <string> An optional suffix to remove

• 返回：<string>

  ¥Returns: <string>

path.basename() 方法返回 path 的最后一部分，类似于 Unix basename 命令。忽略尾随 目录分隔符。

¥The path.basename() method returns the last portion of a path, similar to the Unix basename command. Trailing directory separators are ignored.

path.basename('/foo/bar/baz/asdf/quux.html');
// Returns: 'quux.html'

path.basename('/foo/bar/baz/asdf/quux.html', '.html');
// Returns: 'quux' 拷贝

尽管 Windows 通常以不区分大小写的方式处理文件名（包括文件扩展名），但此函数不会。例如，C:\\foo.html 和 C:\\foo.HTML 指的是同一个文件，但 basename 将扩展名视为区分大小写的字符串：

¥Although Windows usually treats file names, including file extensions, in a case-insensitive manner, this function does not. For example, C:\\foo.html and C:\\foo.HTML refer to the same file, but basename treats the extension as a case-sensitive string:

path.win32.basename('C:\\foo.html', '.html');
// Returns: 'foo'

path.win32.basename('C:\\foo.HTML', '.html');
// Returns: 'foo.HTML' 拷贝

如果 path 不是字符串，或者如果给定 suffix 并且不是字符串，则抛出 TypeError。

¥A TypeError is thrown if path is not a string or if suffix is given and is not a string.
