1、下载phantomjs

http://phantomjs.org/

2、运行

新建phantomjs.bat，记得改目录路径

里面内容为：

D:\java\phantomjs\phantomjs.exe D:\java\phantomjs\code\server.js 8080

3、新建server.js文件，放在code目录下，注意code目录也是新建的，以下是server.js内容

if (s=== "success" ) {            page.evaluate(function () {                $(".canvas_box").appendTo(".app_box").css("float","none").siblings().remove();                $(".app_box,body").css("margin",0);            });            var base64= page.renderBase64('png'),type="data:image/png;base64,"            var img=""            res.write(img);            res.close();        }var page = require('webpage').create();var server = require('webserver').create();var sys = require('system');if(sys.args.length !== 2){    console.log('args is error,demo: phantomjs server.js 80');    phantom.exit(1);}else{    console.log("welcome! system is start on port:"+sys.args[1]+"\ntest url is: http://localhost/http://www.baidu.com");} var port = sys.args[1]; //输出到网页预览图片,地址:http://localhost/http://www.baidu.com/*service = server.listen(port,function(req, res){    var url=decodeURIComponent(req.url).substr(1);    res.statusCode = 200;    res.headers = {        'Cache': 'no-cache',        'Content-Type': 'text/html;charset=utf-8'    };    page.open(url, function (s) {        if (s=== "success" ) {            page.evaluate(function () {                $(".canvas_box").appendTo(".app_box").css("float","none").siblings().remove();                $(".app_box,body").css("margin",0);            });            var base64= page.renderBase64('png'),type="data:image/png;base64,"            var img=""            res.write(img);            res.close();        }    });});*///输出base64字符串service = server.listen(port,function(req, res){    var url=decodeURIComponent(req.url).substr(1);    res.statusCode = 200;    res.headers = {        'Cache': 'no-cache',        'Content-Type': 'text/html;charset=utf-8'    };    page.open(url,/*{ keepAlive: true },*/ function (s) {       var base64= page.renderBase64('png');        res.write(base64);        res.close();    });});

4：訪问地址

localhost:8080/http://baidu.com
