快递100 java 示例API 返回结果乱码之替代方案

快递100官方给出的java 版示例API无法使用，返回结果全是乱码，只能自己写一个。

采用httpClient，不采用官方给出的URL方式。返回结果编码方式为UTF-8。

import java.io.InputStream;
import java.io.InputStreamReader;
import org.apache.commons.httpclient.DefaultHttpMethodRetryHandler;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.methods.GetMethod;
import org.apache.commons.httpclient.params.HttpMethodParams;
