这个是中国期刊网的检索请求，我现在需要通过这个来获取检索出来的信息，解决方法已经有了，就是得不到检索信息，查询内容是空的。
应该是少add了一些检索所需内容。

下面是我的代码

1import java.io.IOException;
2import java.util.Calendar;
3import java.util.GregorianCalendar;
4import org.apache.commons.httpclient.HttpClient;
5import org.apache.commons.httpclient.HttpException;
6import org.apache.commons.httpclient.HttpStatus;
7import org.apache.commons.httpclient.methods.PostMethod;

14PostMethod postMethod = new PostMethod("http://lsg.cnki.net/grid20/Brief.aspx?ID=1&classtype=&systemno=&NaviDatabaseName=&NaviField=");
15postMethod.addParameter("advancedvalue1","java");
16postMethod.addParameter("advancedfield1","主题");
17postMethod.addParameter("yearstart","1979");

30HttpClient client = new HttpClient();
31client.setConnectionTimeout(1000 * 60);
32int status=0;
33try {
34status = client.executeMethod(postMethod);
35} catch (HttpException e) {

41}
42if(status==HttpStatus.SC_OK) {
43makeResponseObject(postMethod.getResponseBodyAsString());
44} else {
45}
46postMethod.releaseConnection();

53String regExNums = ""FONT-SIZE:\\s*9pt;\\s*COLOR:\\s*#000000;\\s*WORD-WRAP:\\s*break-word\"\\s*vAlign=center\\s*bgColor=#f4f5f6\\s*height=30>\\s*共有记录\\s*(\\d+)\\s*条\\s* \\s*";
