问题描述

问 题

网址是这个http://www.zwsw.gov.cn/zwsw20...
我想用jsoup下载这个网址的表格，从源代码看到还挺简单，但是jsoup每次抓到的document只有网页基本信息。希望大神知道一下！谢谢！！

输出为：
<html>
<head>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8">
<title>珠江委水文水资源网</title>
</head>
<body onload="t3_ar_guard();">
<script>
function t3_ar_guard() {
eval(function(p,a,c,k,e,d){e=function(c){return c};if(!''.replace(/^/,String)){while(c--){d[c]=k[c]||c}k=[function(e){return d[e]}];e=function(){return'\w+'};c=1};while(c--){if(k[c]){p=p.replace(new RegExp('\b'+e(c)+'\b','g'),k[c])}}return p}('0.3="4=7/6;5=/";0.2.1=0.2.1;',8,8,'document|href|location|cookie|ant_stream_58ee42b978925|path|474259458|1504312292'.split('|'),0,{}))}
</script>

</body>
</html>

代码为：

 String html2 = "http://www.zwsw.gov.cn/zwsw2011/asp/sqxq/main_sqxq.asp";
     Document doc = Jsoup.connect(html2).get();
     System.out.println(doc);

解决方案

public class Main {
    public static void main(String[] args) throws IOException {
        Document doc = Jsoup.connect("http://www.zwsw.gov.cn/zwsw2011/asp/sqxq/main_sqxq.asp").cookie("ant_stream_58ee42b978925","1504345521/771910499").get();
        Element body = doc.body();
        System.out.println(body.html());
    }
}

添加一下cookie值就可以拿到了。
输出如下：
