我试图通过嵌入所有图像(以及我通过此点后的其他外部资源)将网页转换为单个文件.以下是我运行PhantomJs的方法:

./phantomjs --web-security=false ./embed_images.js http://localhost/index.html > output.txt

这是embed_images.js:

var page = require('webpage').create(),
    system = require('system'),
    address;

if (system.args.length === 1) {

    page.open(address, function(status) {
        page.evaluate(function() {
            function embedImg(org) {
                var img = new Image();
                img.src = org.src;
                img.onload = function() {
                    var canvas = document.createElement("canvas");
                    canvas.width = this.width;
                    canvas.height = this.height;

                    var ctx = canvas.getContext("2d");
                    ctx.drawImage(this, 0, 0);
