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
1 import 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;
