path.resolve([...paths])

• ...paths <string> 路径或路径片段的序列

  ¥...paths <string> A sequence of paths or path segments

• 返回：<string>

  ¥Returns: <string>

path.resolve() 方法将路径或路径片段的序列解析为绝对路径。

¥The path.resolve() method resolves a sequence of paths or path segments into an absolute path.

给定的路径序列从右到左处理，每个后续的 path 会被追加到前面，直到构建绝对路径。例如，给定路径段的顺序：/foo、/bar、baz，调用 path.resolve('/foo', '/bar', 'baz') 将返回 /bar/baz，因为 'baz' 不是绝对路径，但 '/bar' + '/' + 'baz' 是。

¥The given sequence of paths is processed from right to left, with each subsequent path prepended until an absolute path is constructed. For instance, given the sequence of path segments: /foo, /bar, baz, calling path.resolve('/foo', '/bar', 'baz') would return /bar/baz because 'baz' is not an absolute path but '/bar' + '/' + 'baz' is.

如果在处理完所有给定的 path 片段之后，还没有生成绝对路径，则使用当前工作目录。

¥If, after processing all given path segments, an absolute path has not yet been generated, the current working directory is used.

生成的路径被规范化，并删除尾部斜杠（除非路径解析为根目录）。

¥The resulting path is normalized and trailing slashes are removed unless the path is resolved to the root directory.

零长度的 path 片段被忽略。

¥Zero-length path segments are ignored.

如果没有传入 path 片段，则 path.resolve() 将返回当前工作目录的绝对路径。

¥If no path segments are passed, path.resolve() will return the absolute path of the current working directory.

path.resolve('/foo/bar', './baz');
// Returns: '/foo/bar/baz'

path.resolve('/foo/bar', '/tmp/file/');
// Returns: '/tmp/file'

path.resolve('wwwroot', 'static_files/png/', '../gif/image.gif');
// If the current working directory is /home/myself/node,
// this returns '/home/myself/node/wwwroot/static_files/gif/image.gif' 拷贝

如果任何参数不是字符串，则抛出 TypeError。

¥A TypeError is thrown if any of the arguments is not a string.
