Java 从网页抽取数据 存入数据库

台风的编号和名称直接在源码中有，但时间和地理位置我只能跟踪到

function totf(tfbh){

location.href( "Typhoon.aspx?id="+tfbh)

}

数据需要从aspx中拿到的，应该是存放到数据库的，页面上是拿不到的

我认为可以通过循环模拟发送请求Typhoon.aspx?id="+XXX，然后通过解析response包的方式可以获得详细的信息

下面一个页面是讲模拟发送请求的

希望对你有帮助

我写了一段获得一组数据的代码

//get Typhoon content by param

public static String getTyphoon(String param) {

URL url = null

try {

url = new URL(param)

} catch (MalformedURLException e) {

e.printStackTrace()

}

HttpURLConnection connection = null

InputStream is = null

try {

connection = (HttpURLConnection) url.openConnection()

is = connection.getInputStream()

} catch (IOException e) {

e.printStackTrace()

}

BufferedInputStream bis = new BufferedInputStream(is)

int len = 0

byte[] buf_all = new byte[0]

try {

while (true) {

byte[] buf1 = new byte[4096]

byte[] buf2 = buf_all

len = bis.read(buf1)

if(len <= 0){

break

}

buf_all = new byte[len+buf2.length]

System.arraycopy(buf2, 0, buf_all, 0, buf2.length)

System.arraycopy(buf1, 0, buf_all, buf2.length, len)

}

} catch (IOException e) {

e.printStackTrace()

}

String content = null

try {

content = new String(buf_all, "utf-8")

} catch (UnsupportedEncodingException e) {

e.printStackTrace()

}

int startIndex = content.indexOf("var ary0=")+9

content = content.substring(startIndex)

int endIndex = content.indexOf("var aryyb0=")

content = content.substring(0, endIndex)

return content

}

得到的结果是这样的：

再下去字符串的拆分实在是太复杂了，不想写了

使用时只要参数为http://www.wztf121.com/Typhoon.aspx?id=

id后是台风的代码号，写一个循环就可以了

受台风外围影响，今天白天深圳以多云为主，持续炎热，白天风力开始有所增强，夜间风力进一步加大，陆地最大平均风逐步增加到5-6级，阵风7-8级，沿海6-7级，阵风9-10级明天将有一次暴雨、局部大暴雨的降水过程，这次降雨将在10月1日结束。

“纳沙”比起刚刚过境的“海棠”，移动更快、强度更强、范围更广、破坏更大，由于碰巧又跟北方冷空气相遇，风力进一步增大，影响时间也较长，可能出现狂风骤雨的情况。而“纳沙”影响期间恰逢天文大潮，市气象台建议有关部门部署防洪排涝工作，防范强降雨可能导致的积涝、道路积水、地质灾害等影响，也呼吁市民合理安排出行计划，预计明晚可能升挂台风蓝色预警信号，并随时发布暴雨预警信号。

超强台风天兔（英语：Severe Tropical Storm Usagi，国际编号：1319，联合台风警报中心：17W，菲律宾大气地球物理和天文管理局：Odette）为2013年太平洋台风季第十七个被命名的风暴。“天兔”一名由日本提供，是天兔星座。预计未来“天兔”将以台风或强台风的等级登陆广东沿海，将有望成为今年登陆我国的最强台风。中央气象台于2013年9月20日下午将台风预警等级提升至橙色。[1-2]预计9月22日下午到23日早晨在广东惠来到台山一带沿海登陆。

最高热带气旋警告信号：台风红色预警信号[9]

9月19日下午6时，中央气象台发布台风黄色预警信号。

9月20日下午6时，中央气象台改发台风橙色预警信号。

9月20日上午6时，中央气象台改发台风红色预警信号。

受超强台风“天兔”影响，国家气象局2013年9月20日启动了Ⅲ级应急响应；2013年9月19日国家海洋局启动海洋灾害Ⅰ级应急响应，要求相关单位展开各项灾害防御工作。

2013年9月21日，深圳市组织参加广东省防御超强台风“天兔”异地视频会商会议，并紧急部署此次台风防御工作。市三防办已于2013年9月21晚启动防风Ⅲ级应急响应，并按要求2013年9月22、23日两天，全市中小学、幼儿园、托儿所停课。[14]
