需要在同一会话中，处理2次请求的做法
1 先获取第一请求的cookie信息
2 把第一次获取的cookie携带给第2次请求
代码如下：
import org.apache.commons.httpclient.HttpException;

"MMwwwURLtel".equalsIgnoreCase(cookie.getName())) {

}
}
rtnCookies = rtnCookies.substring(1);
int statusCode = response.getStatusLine().getStatusCode();
logger.info("获取短信返回状态statusCode===" + statusCode);

//从头中取出转向的地址

return null;
}
