phantomjs

最近做爬虫，基于网页上面有很多ajax请求，可以采用httpclient找到相应的ajax，这样做比较麻烦，然后采用phantomjs,直接可以获取到网页所有信息。
public static String dealWithAjax(String url) throws IOException {    
Runtime rt = Runtime.getRuntime();    
Process p = rt.exec("phantomjs.exe D:\\rj\\RedisImportMysql\\src\\js\\test.js "+url);  
InputStream is = p.getInputStream();    
BufferedReader br = new BufferedReader(new InputStreamReader(is));    
StringBuffer sbf = new StringBuffer();    
String tmp = "";    
while((tmp = br.readLine())!=null){    
sbf.append(tmp);  
sbf.append("\n");
}    
sbf.append("-----------------------------------------------------------------------");
return sbf.toString();    
}    

public static void main(String[] args) throws IOException {    
// System.out.println(getAjaxCotnent("http://shixin.court.gov.cn/personMore.do")); 
String s = dealWithAjax("http://list.tmall.com/search_product.htm?q=%CA%D6%BB%FA&type=p&vmarket=&spm=a222r.7716956.a2227oh.d100&from=..pc_1_searchbutton");
System.out.println(s);
FileUtil.writeFile("d://a.txt", "utf-8", s,true);

}



test.js源码:
//codes.js    
system = require('system')    
address = system.args[1];//获得命令行第二个参数 接下来会用到    
//console.log('Loading a web page');    
var page = require('webpage').create();    
var url = address;  
var newUrl ;
//console.log(url);    
page.open(url, function (status) {    
//Page is loaded!

} else {    
//console.log(page.content);    
var content = page.evaluate(function() {  
//var elements =  document.querySelector("#xy-impcon-B");//示范下如何使用页面的jsapi去操作页面的  www.oicqzone.com
//return elements.innerHTML
return document.querySelector("*").innerHTML;
});
