高級接口，先做了兩個（獲取用戶信息和獲取關(guān)注者列表）

第一步：找到包com.wtz.vo，新建類UserInfo.java

1 package com.wtz.vo; 2 3 /** 4 * @author wangtianze QQ:864620012 5 * @date 2017年4月24日 下午4:51:57 6 * <p>version:1.0</p> 7 * <p>description:微信用戶的基本信息</p> 8 */ 9 public class UserInfo { 10 //用戶的標識 11 private String openId; 12 //關(guān)注狀態(tài)（1是關(guān)注，0是未關(guān)注），未關(guān)注時獲取不到其余信息 13 private int subscribe; 14 //用戶關(guān)注時間，為時間戳，如果用戶曾多次關(guān)注，則取最后關(guān)注時間 15 private String subscribeTime; 16 //昵稱 17 private String nickname; 18 //用戶的性別（1是男性，2是女性，0是未知） 19 private int sex; 20 //用戶所在國家 21 private String country; 22 //用戶所在省份 23 private String province; 24 //用戶所在城市 25 private String city; 26 //用戶的語言，中文為zh_CN 27 private String language; 28 //用戶頭像 29 private String headImgUrl; 30 //unionid 31 private String unionid; 32 33 public String getOpenId() { 34 return openId; 35 } 36 public void setOpenId(String openId) { 37 this.openId = openId; 38 } 39 public int getSubscribe() { 40 return subscribe; 41 } 42 public void setSubscribe(int subscribe) { 43 this.subscribe = subscribe; 44 } 45 public String getSubscribeTime() { 46 return subscribeTime; 47 } 48 public void setSubscribeTime(String subscribeTime) { 49 this.subscribeTime = subscribeTime; 50 } 51 public String getNickname() { 52 return nickname; 53 } 54 public void setNickname(String nickname) { 55 this.nickname = nickname; 56 } 57 public int getSex() { 58 return sex; 59 } 60 public void setSex(int sex) { 61 this.sex = sex; 62 } 63 public String getCountry() { 64 return country; 65 } 66 public void setCountry(String country) { 67 this.country = country; 68 } 69 public String getProvince() { 70 return province; 71 } 72 public void setProvince(String province) { 73 this.province = province; 74 } 75 public String getCity() { 76 return city; 77 } 78 public void setCity(String city) { 79 this.city = city; 80 } 81 public String getLanguage() { 82 return language; 83 } 84 public void setLanguage(String language) { 85 this.language = language; 86 } 87 public String getHeadImgUrl() { 88 return headImgUrl; 89 } 90 public void setHeadImgUrl(String headImgUrl) { 91 this.headImgUrl = headImgUrl; 92 } 93 public String getUnionid() { 94 return unionid; 95 } 96 public void setUnionid(String unionid) { 97 this.unionid = unionid; 98 } 99 }

?

第二步：找到包com.wtz.vo，新建類UserList.java

1 package com.wtz.vo; 2 3 import java.util.List; 4 5 /** 6 * @author wangtianze QQ:864620012 7 * @date 2017年4月24日 下午5:08:28 8 * <p>version:1.0</p> 9 * <p>description:關(guān)注的用戶列表</p> 10 */ 11 public class UserList { 12 //公眾賬號的總關(guān)注用戶數(shù) 13 private int total; 14 //獲取的openId個數(shù) 15 private int count; 16 //OpenID列表 17 private List<String> openIdList; 18 //拉取列表的后一個用戶的OPENID 19 private String nextOpenId; 20 21 public int getTotal() { 22 return total; 23 } 24 public void setTotal(int total) { 25 this.total = total; 26 } 27 public int getCount() { 28 return count; 29 } 30 public void setCount(int count) { 31 this.count = count; 32 } 33 public List<String> getOpenIdList() { 34 return openIdList; 35 } 36 public void setOpenIdList(List<String> openIdList) { 37 this.openIdList = openIdList; 38 } 39 public String getNextOpenId() { 40 return nextOpenId; 41 } 42 public void setNextOpenId(String nextOpenId) { 43 this.nextOpenId = nextOpenId; 44 } 45 }

?

第三步：找到包com.wtz.vo，新建類WeixinGroup.java

1 package com.wtz.vo; 2 3 /** 4 * @author wangtianze QQ:864620012 5 * @date 2017年4月24日 下午5:24:57 6 * <p>version:1.0</p> 7 * <p>description:公眾賬號分組信息</p> 8 */ 9 public class WeixinGroup { 10 //分組id 11 private int id; 12 //分組名稱 13 private String name; 14 //分組內(nèi)的用戶數(shù) 15 private int count; 16 17 public int getId() { 18 return id; 19 } 20 public void setId(int id) { 21 this.id = id; 22 } 23 public String getName() { 24 return name; 25 } 26 public void setName(String name) { 27 this.name = name; 28 } 29 public int getCount() { 30 return count; 31 } 32 public void setCount(int count) { 33 this.count = count; 34 } 35 }
