fs.cp(src, dest[, options], callback)

• src <string> | <URL> 要复制的源路径。

  ¥src <string> | <URL> source path to copy.

• dest <string> | <URL> 要复制到的目标路径。

  ¥dest <string> | <URL> destination path to copy to.

• options <Object>

  • dereference <boolean> 取消引用符号链接。默认值：false。

    ¥dereference <boolean> dereference symlinks. Default: false.

  • errorOnExist <boolean> 当 force 是 false 且目标存在时，抛出错误。默认值：false。

    ¥errorOnExist <boolean> when force is false, and the destination exists, throw an error. Default: false.

  • filter <Function> 过滤复制文件/目录的函数。返回 true 则复制条目，返回 false 则忽略它。忽略目录时，其所有内容也将被跳过。还可以返回解析为 true 或 false 默认值的 Promise：undefined。

    ¥filter <Function> Function to filter copied files/directories. Return true to copy the item, false to ignore it. When ignoring a directory, all of its contents will be skipped as well. Can also return a Promise that resolves to true or false Default: undefined.

    • src <string> 要复制的源路径。

      ¥src <string> source path to copy.

    • dest <string> 要复制到的目标路径。

      ¥dest <string> destination path to copy to.

    • 返回：<boolean> | <Promise> 可强制转换为 boolean 的值或满足该值的 Promise。

      ¥Returns: <boolean> | <Promise> A value that is coercible to boolean or a Promise that fulfils with such value.

  • force <boolean> 覆盖现有文件或目录。如果将此设置为 false 并且目标存在，则复制操作将忽略错误。使用 errorOnExist 选项更改此行为。默认值：true。

    ¥force <boolean> overwrite existing file or directory. The copy operation will ignore errors if you set this to false and the destination exists. Use the errorOnExist option to change this behavior. Default: true.

  • mode <integer> 复制操作的修饰符。默认值：0。参见 fs.copyFile() 的 mode 标志。

    ¥mode <integer> modifiers for copy operation. Default: 0. See mode flag of fs.copyFile().

  • preserveTimestamps <boolean> 当为 true 时，则 src 的时间戳将被保留。默认值：false。

    ¥preserveTimestamps <boolean> When true timestamps from src will be preserved. Default: false.

  • recursive <boolean> 递归复制目录默认：false

    ¥recursive <boolean> copy directories recursively Default: false

  • verbatimSymlinks <boolean> 当为 true 时，则符号链接的路径解析将被跳过。默认值：false

    ¥verbatimSymlinks <boolean> When true, path resolution for symlinks will be skipped. Default: false

• callback <Function>

  • err <Error>

将整个目录结构从 src 异步地复制到 dest，包括子目录和文件。

¥Asynchronously copies the entire directory structure from src to dest, including subdirectories and files.

当将目录复制到另一个目录时，不支持 globs，并且行为类似于 cp dir1/ dir2/。

¥When copying a directory to another directory, globs are not supported and behavior is similar to cp dir1/ dir2/.
