java 数据抓取 serlvert 乱码问题
访问http://59.151.28.39/

public void captureJavascript(String queryTypeValue,String carMarkTValue,String VINNoValue) throws Exception {
String strURL = "http://59.151.28.39/servlet/SocietyUserQueryServlet?queryType="+queryTypeValue+"&carMarkT="+carMarkTValue+"&VINNo="+VINNoValue;
URL url = new URL(strURL);
HttpURLConnection httpConn = (HttpURLConnection) url.openConnection();
InputStreamReader input = new InputStreamReader(httpConn
.getInputStream(), "gbk");
BufferedReader bufReader = new BufferedReader(input);
String line = "";
StringBuilder contentBuf = new StringBuilder();
while ((line = bufReader.readLine()) != null) {
contentBuf.append(line);
}
System.out.println(strURL);
System.out.println("captureJavascript()的结果：\n" + contentBuf.toString());
}
demo.captureJavascript("thirdQueryMode", "京YZ1010", "LHGCP168882020305");

中文传递解析乱码，返回数据都是空，
求大神帮忙

应该是他后台有处理了你直接浏览器敲过去，所以你模拟请求会得到以下的结果。

http://59.151.28.39/servlet/SocietyUserQueryServlet?queryType=thirdQueryMode&carMarkT=%E4%BA%ACYZ1010&VINNo=LHGCP168882020305


  号牌号码：???YZ1010 , 车架号：LHGCP168882020305  的理赔信息：

  交强险理赔信息

未查询到交强险理赔信息!

  商业险理赔信息

未查询到商业险理赔信息!

其实最后生成的是

<table border='0' width='100%' align='center' cellpadding='0' cellspacing='0'><tr class='table_td_condition'><td>&nbsp;&nbsp;<span class='table_td_condition1'>号牌号码：京YZ1010</span>&nbsp;,&nbsp;<span class='table_td_condition1'>车架号：LHGCP168882020305</span>&nbsp;&nbsp;的理赔信息：</td></tr><tr><td><table border='0' width='99%' align='center' cellpadding='0' cellspacing='0'><tr><td class='rightDowenTitleCss' colspan='11'>&nbsp;&nbsp;交强险理赔信息</td></tr><tr height='10px'><td></td></tr><tr height='50' class='queryOperationInf'><td>未查询到交强险理赔信息!</td></tr></table></td></tr><tr height='15'><td></td></tr><tr><td><table border='0' width='99%' align='center' cellpadding='0' cellspacing='0'><tr><td class='rightDowenTitleCss' colspan='11'>&nbsp;&nbsp;商业险理赔信息</td></tr><tr height='30' class='thCss'><th>公司名称</th><th>号牌号码</th><th>号牌种类</th><th>出险时间</th><th>出险地点</th><th>报案时间</th><th>立案时间</th><th>结案时间</th><th>案件状态</th><th>赔款金额</th><th>联系电话</th></tr><tr class='tdCss'><td>人保</td><td>京YZ1010</td><td>小型汽车号牌</td><td>2013-06-02</td><td>房山区良乡</td><td>2013-06-02</td><td>2013-06-03</td><td>2013-06-13</td><td>已结案</td><td align='right'>1615.00</td><td>&nbsp;58195470</td></tr></table></td></tr><tr height='15'><td></td></tr></table>

刚才测试写错。你现在试下。

public static void captureJavascript(String queryTypeValue, String carMarkTValue,

			String VINNoValue) throws Exception {


		String strURL = "http://59.151.28.39/servlet/SocietyUserQueryServlet";

		URL url = new URL(strURL);

		HttpURLConnection httpConn = (HttpURLConnection) url.openConnection();


		httpConn.setDoOutput(true);

		httpConn.setRequestMethod("POST");

		httpConn.connect();


		OutputStream out = httpConn.getOutputStream();

		String param= "queryType="

		+ "thirdQueryMode"

		+ "&carMarkT="

		+ "京YZ1010"

		+ "&VINNo="

		+ "LHGCP168882020305";

		out.write(param.getBytes());


		out.flush();

		out.close();

		BufferedReader reader = new BufferedReader(new InputStreamReader(httpConn

				.getInputStream(),"GBK"));

		String line;

		StringBuffer buffer = new StringBuffer();

		while ((line = reader.readLine()) != null) {

			buffer.append(line);

		}

		reader.close();

		httpConn.disconnect();

		System.out.println(buffer.toString());

	}
