Instructions for using the fs.symlink method in node.js_node.js

Method description:

Create a symbolic link.

Grammar:

Copy code The code is as follows:

fs.symlink(srcpath, dstpath, [type], [callback(err)])

Since this method belongs to the fs module, the fs module needs to be introduced before use (var fs= require(“fs”) )

Receive parameters:

srcpath is the path of the source directory or file

dstpath It is the path to store the converted directory. The default is the current working directory

type                                                                                 Default value: 'file', optional values ​​'dir', 'file', or 'junction', this item is only used on Windows (ignored on other platforms).

Note that the directory that Windows nodes need to convert is an absolute path. When using "junction", the target parameters will be automatically normalized to the absolute path.

callback callback, passing an exception parameter err

Source code:

Copy code The code is as follows:

fs.symlink = function(destination, path, type_, callback) {
var type = (util.isString(type_) ? type_ : null);
var callback = makeCallback(arguments[arguments.length - 1]);
if (!nullCheck(destination, callback)) return;
if (!nullCheck(path, callback)) return;
binding.symlink(preprocessSymlinkDestination(destination, type),
pathModule._makeLong(path),
                 type,
                  callback);
};
