五、利用httpclient测试手机号码归属地接口

indexof()用法

package com.netease;

import org.apache.commons.lang3.StringEscapeUtils;

public class HttpClientJemter {

    public static CloseableHttpClient httpClient = null;

    @BeforeClass
    public static  void setUp(){
        httpClient = HttpClients.createDefault();
    }
    @Test
    public void phoneTest() throws ClientProtocolException , IOException {
        String phone = "13521275380";
        HttpGet httpGet = new HttpGet("http://tcc.taobao.com/cc/json/mobile_tel_segment.htm?tel="+phone);
        httpGet.addHeader("EagleEye-TraceId","0b5205fc15872856373491041e0635");
        CloseableHttpResponse res = httpClient.execute(httpGet);
        try{
            int statusCode = res.getStatusLine().getStatusCode();
            System.out.println(statusCode);
            String resBody = EntityUtils.toString(res.getEntity());
            System.out.println(resBody);
            int t1 = resBody.indexOf("province")+9;
            int t2 = resBody.indexOf("\'",t1);
            String city = resBody.substring(t1,t2);  //根据两个双引号截取city的内容
            city = StringEscapeUtils.unescapeJava(city);//将转换成中文，即可获得归属地
            System.out.println(city);

        }finally {
            res.close();
        }
    }
}
