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'
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.
