phantomjs搭建輸出js渲染後的html接口

接觸過爬蟲的人都知道，有不少html是js渲染後纔有數據給予解析的，php執行JavaScript能夠有V8 javascript engine，要想獲取渲染後的html也能夠直接使用

php的擴展  querylist 採集，文檔：

https://www.querylist.cc/docs/guide/v4/PhantomJS

不過這裏想聊聊phantomjs的api接口文檔，之前只會命令行模式的phantomjs指令 + php的exec函數執行JavaScript代碼

phantomjs的api：

http://phantomjs.org/api/

接口功能：提供一個接口地址，傳入網址返回渲染後的html（字符串）

使用webserver模式：phantomjs可執行文件執行js文件，就會監聽端口，當有請求進來以後就會返回渲染後的html

var webserver = require('webserver');
var server = webserver.create();

var pageInfo = {};

var action = {'openUrl':true,'parseJs':true};

var service = server.listen(8888, function(request, response) {
    post = request.post;
    var opera = (typeof post.action != 'undefined' && typeof action[post.action] != 'undefined') ? post.action : 'openUrl';
    
    var webPage = require('webpage');
    var page = webPage.create();
    if(opera == 'openUrl') {// 打開URL頁面
        pageInfo['url'] = (typeof post.url != 'undefined') ? post.url : '';
        pageInfo['postData'] = (typeof post.postData != 'undefined') ? post.postData : '';
        pageInfo['loadSource'] = (typeof post.loadSource != 'undefined' && post.loadSource == 'no') ? false : true;
        
        
        var body = '';
        
        if(pageInfo['loadSource'] === false) {
            page.settings.javascriptEnabled = false;
            page.settings.loadImages = false;
        }
        
        if(pageInfo.url) {
            page.open(pageInfo.url, function(status) {
                body = page['content'];
                console.log('url:'+pageInfo.url);
                console.log('Status: ' + status);
                
                response.statusCode = 200;
                response.write(body);
                response.close();
            })
        } else {
            response.statusCode = 200;
            response.write('請傳URL');
            response.close();
        }
    } else if(opera == 'parseJs') {// 解析JS

注意監聽的端口不要已經被使用了哦
