首先申请key值，天行、聚合等都行，我用的是聚合数据免费的查询号码归属地api，到聚合数据注册进行实名认证后可以获取到key值，这个很重要，没有请求不了数据。

实现效果：

分析

首先测试一下接口，看看它返回的json数据：

接口地址：

http://apis.juhe.cn/mobile/get

请求参数中phone为必填，魔人返回json格式

返回的数据内容：

{
	"resultcode":"200",
	"reason":"Return Successd!",
	"result":{
		"province":"广东",
		"city":"广州",
		"areacode":"020",
		"zip":"510000",
		"company":"电信",
		"card":""
	},
	"error_code":0
}

返回的数据内容中为resultcode、reason、result、error_code。其中result又嵌套province、city、areacode、zip、company、card

根据号码模拟测试我们可以获取如下信息：

 * 手机号码段	180xxxxxx
 * 卡号归属地	省份 城市
 * 运营商	xx
 * 区号	xxx
 * 邮编	xxxxxx

添加依赖

在项目的app目录下的build.gradle里面添加如下：
然后再同步构建一下。

implementation("com.squareup.okhttp3:okhttp:4.9.0")
implementation 'com.google.code.gson:gson:2.7'

PhoneBean.class

从上面我们提取有用的值，并写相应的Bean类：PhoneBean.class

package com.lyx.mycommunity.bean;
/**

/**

 *         "city":"广州",

public class JsonBean {
    public String resultcode;
    public String reason;

    public static class Result {

        }

        public String getCard() {
            return card;
        }

        public void setCard(String card) {
            this.card = card;
        }
    }


    @Override
    public String toString() {
        return "JsonBean{" +
                "reason='" + reason + '\'' +
                ", resultcode='" + resultcode + '\'' +
                ", result=" + result +
                '}';
    }
}
