PhantomJS

phantomjs 加ua以及设置中文编码的方式，如下面这两句代码所示，如果不设置中文编码，redhat环境下是乱码的

    page.settings.userAgent='Mozilla/6.0 (iPhone; CPU iPhone OS 8_0 like Mac OS X) AppleWebKit/536.26 (KHTML, like Gecko) Version/8.0 Mobile/10A5376e Safari/8536.25';
    phantom.outputEncoding = "gb2312";

先安装字体

yum install bitmap-fonts bitmap-fonts-cjk 

"use strict";
var page = require('webpage').create(),
    system = require('system'),
    address, output, size;
    page.settings.userAgent='Mozilla/6.0 (iPhone; CPU iPhone OS 8_0 like Mac OS X) AppleWebKit/536.26 (KHTML, like Gecko) Version/8.0 Mobile/10A5376e Safari/8536.25';
    phantom.outputEncoding = "gb2312";
    if (system.args.length < 3 || system.args.length > 5) {
    console.log('Usage: rasterize.js URL filename [paperwidth*paperheight|paperformat] [zoom]');
    console.log('  paper (pdf output) examples: "5in*7.5in", "10cm*20cm", "A4", "Letter"');
    console.log('  image (png/jpg output) examples: "1920px" entire page, window width 1920px');
    console.log('                                   "800px*600px" window, clipped to 800x600');
    phantom.exit(1);
} else {
    address = system.args[1];
    output = system.args[2];
    page.viewportSize = { width: 414, height: 736 };
    if (system.args.length > 3 && system.args[2].substr(-4) === ".pdf") {

    }
    if (system.args.length > 4) {
