我正在尝试使用Jsoup废弃网页。 Jsoup似乎不像Chrome那样捕获<input元素。
缺少这些值：
<input type="hidden" id="fileId" value="3168935269">
<input type="hidden" id="secondsLeft" value="20">
使用Jsoup我提取了这些元素：

使用try.jsoup.com也没有产生像Chrome这样的输入类型，这表明它不是我的代码，而是Jsoup。
通过其他线程阅读表明Javascript可能在加载网页后更改了html。关于如何解决这个问题没有可行的答案。
我做错了什么以及如何解决？
这是我获取完整html页面的代码：
Document doc = Jsoup.connect("http://www.4shared.com/get/i-EbooI0/batman_hd.html").timeout(0).get();
System.out.println(doc.toString() + "\n\n\n\n");
Elements links = doc.select("input[type=hidden]");
for (org.jsoup.nodes.Element link : links) {
System.out.println(link);
}
在此处查看所需值的屏幕截图
解
Connection.Response response = Jsoup.connect("myUrl")
.method(Connection.Method.GET)
.execute();
Document homePage = Jsoup.connect("myUrl")
.cookies(response.cookies())
.get();
此处描述的修改版代码：Jsoup Cookies for HTTPS scraping。这将获取Niranjan建议的cookie，然后重新连接到您的Url。

答案 0 :(得分：5)
Jsoup会在解析时清除您的HTML内容，并且它可以处理您的HTML，尽管它的格式不正确。尝试在解析之后转储html，Document.html()并检查转储，如果丢弃的元素符合select子句的条件。
更新
在这里，试试看，如果有效，我会向你解释一下!!
public static void main(String[] args) throws IOException
{
try
{
Map<String, String> cookieMap = new HashMap<String, String>();
cookieMap.put("day1host", "h");
cookieMap.put("d1.loginity.mark", "1");
cookieMap.put("hostid", "-1314014314");
cookieMap.put("__qca", "P0-2042580316-1371938383086");
cookieMap.put("cd1v", "OOhB");
cookieMap.put("c29", "1");
cookieMap.put("__utma", "210074320.280144312.1371938377.1371938377.1371938377.1");
cookieMap.put("__utmb", "210074320.4.10.1371938377");
cookieMap.put("__utmc", "210074320");
cookieMap.put("__utmz", "210074320.1371938377.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none)");
Document document = Jsoup.connect("http://www.4shared.com/get/i-EbooI0/batman_hd.html")
.userAgent("Mozilla/5.0 (Windows NT 5.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/27.0.1453.110 Safari/537.36")
.followRedirects(true)
.cookies(cookieMap)
.get();
//System.out.println(document.html());
//System.out.println("====================================================================");
Elements elements = document.select("input[type=hidden]");
for (Iterator<Element> iterator = elements.iterator(); iterator.hasNext();)
{
Element element = iterator.next();
System.out.println(element);
}
}
catch (Exception e)
{
e.printStackTrace();
}
}
说明
我不确定您尝试的所有URL下面的模式是否相同。
这就是网站的响应方式。
-
从
/get/i-EbooI0/batman_hd.html到android/i-EbooI0/batman_hd.html的网站重定向。 在重定向时发送2个cookie以响应第一个请求。
-
第二次请求中有更多Cookie。
<body>中没有隐藏字段。确认这一点，查看Elements标签。 -
现在在浏览器中请求
http://www.4shared.com/get/i-EbooI0/batman_hd.html。
现在，您在＆lt;
中拥有所需的Hidden fields。body>
我直接在代码中执行
Step 3。
结论：
如果您对其他
URL也观察到相同的行为，那么您必须编写代码以捕获cookies的{{1}}，然后在随后的Response中传递它们{1}}直到您获得所需的Request。
