PhantomJS - 复制

此方法有助于将文件从一个位置复制到另一个位置。它有两个参数。第一个参数是源文件，第二个参数是文件路径，必须将文件复制到该路径。如果源文件或目标文件不存在，它会抛出错误。

语法

其语法如下 -

var  fs = require('fs');
fs.copy(sourcefile,destinationfile);

示例

var fs = require('fs'); 
var system = require('system'); 
var path1 = system.args[1]; 
var path2 = system.args[2]; 

console.log("Checking to see if source is a file:" + fs.isFile(path1)); 
console.log("Checking to see if destination is a file:" + fs.isFile(path2)); 
console.log("copying file from source to destination"); 
fs.copy(path1,path2); 

console.log("Checking to see if destination is a file:" + fs.isFile(path2)); 
console.log("contents from file are:"); 
console.log(fs.read(path2));

上述程序生成以下输出。

var fs = require('fs'); 
var system = require('system'); 
var path1 = system.args[1]; 
var path2 = system.args[2]; 
console.log("Checking to see if source is a file:" + fs.isFile(path1)); 
console.log("Checking to see if destination is a file:" + fs.isFile(path2)); 
console.log("copying file from source to destination"); 
fs.copy(path1,path2); 
console.log("Checking to see if destination is a file:" + fs.isFile(path2)); 
console.log("contents from file are:"); 
console.log(fs.read(path2));
