服务端实现app授权登录

1.老规矩，导入jar包

<!--后台查询微信用户信息-->
<dependency><groupId>com.github.liyiorg</groupId><artifactId>weixin-popular</artifactId><version>2.8.5</version></dependency>

2.工具类

}

3.信任管理

package com.es.biz.common.utils;import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import javax.net.ssl.X509TrustManager;/*** 描述:信任管理器 </br>* 发布版本：V1.0 </br>*/
/** 证书管理器的作用是让它新人我们指定的证书，* 此类中的代码意味着信任所有的证书，不管是不是权威机构颁发的。*/
public class WechatTrustManager implements X509TrustManager {// 检查客户端证书public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {}// 检查服务器端证书public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {}// 返回受信任的X509证书数组public X509Certificate[] getAcceptedIssuers() {return null;}
}

4.微信用户详情实体类

package com.es.biz.modules.user.entity.wechat;import java.io.Serializable;/*** 用户管理InfoVO** @author es* @email es@126.com*/
public class WechatUserEntity implements Serializable {private static final long serialVersionUID = 1L;/*** 用户的标识*/private String openId;/*** 关注状态（1是关注，0是未关注），未关注时获取不到其余信息*/private int subscribe;/*** 用户关注时间，为时间戳。如果用户曾多次关注，则取最后关注时间*/private String subscribeTime;/*** 昵称*/private String nickname;/*** 用户的性别（1是男性，2是女性，0是未知）*/private int sex;/*** 用户所在国家*/private String country;/*** 用户所在省份*/private String province;/*** 用户所在城市*/private String city;/*** 用户的语言，简体中文为zh_CN*/private String language;/*** 用户头像*/private String headImgUrl;/*** 用户特权信息*/private String PrivilegeList;/*** 微信授权用户唯一标识*/private String unionId;public String getOpenId() {return openId;}public void setOpenId(String openId) {this.openId = openId;}public int getSubscribe() {return subscribe;}public void setSubscribe(int subscribe) {this.subscribe = subscribe;}public String getSubscribeTime() {return subscribeTime;}public void setSubscribeTime(String subscribeTime) {this.subscribeTime = subscribeTime;}public String getNickname() {return nickname;}public void setNickname(String nickname) {this.nickname = nickname;}public int getSex() {return sex;}public void setSex(int sex) {this.sex = sex;}public String getCountry() {return country;}public void setCountry(String country) {this.country = country;}public String getProvince() {return province;}public void setProvince(String province) {this.province = province;}public String getCity() {return city;}public void setCity(String city) {this.city = city;}public String getLanguage() {return language;}public void setLanguage(String language) {this.language = language;}public String getHeadImgUrl() {return headImgUrl;}public void setHeadImgUrl(String headImgUrl) {this.headImgUrl = headImgUrl;}public String getPrivilegeList() {return PrivilegeList;}public void setPrivilegeList(String privilegeList) {PrivilegeList = privilegeList;}public String getUnionId() {return unionId;}public void setUnionId(String unionId) {this.unionId = unionId;}
}

5.微信token实体类

package com.es.biz.modules.user.entity.wechat;/*** 描述: 凭证 </br>* 发布版本：V1.0 </br>*/
public class WechatTokenEntity {/*** 接口访问凭证֤*/private String accessToken;/*** 接口访问凭证֤，刷新*/private String refreshToken;/*** 凭证有效期单位：second*/private int expiresIn;/*** 授权用户唯一标识*/private String openid;/*** 微信用户唯一标识*/private String unionId;public String getOpenid() {return openid;}public void setOpenid(String openid) {this.openid = openid;}public String getAccessToken() {return accessToken;}public void setAccessToken(String accessToken) {this.accessToken = accessToken;}public int getExpiresIn() {return expiresIn;}public void setExpiresIn(int expiresIn) {this.expiresIn = expiresIn;}public String getUnionId() {return unionId;}public void setUnionId(String unionId) {this.unionId = unionId;}public String getRefreshToken() {return refreshToken;}public void setRefreshToken(String refreshToken) {this.refreshToken = refreshToken;}
}

就这么多了，多测试一下，^ ^
