微信登录前后端根据openid 手机号

1.最近在开发小程序的项目中，服务端需要配合前端获取当前用户与微信绑定的手机号；需要以下两步：
1.1根据前端所传的code通过服务端调微信接口获取openId,sessionkey;
1.2根据前端所传的encrypdata，ivdata，sessionKey服务端进行解密后得到手机号

2.登录根绝凭证appId和appSecret校验。通过 wx.login 接口获得临时登录凭证 code 后传到开发者服务器调用此接口完成登录流程，然后后端通过code值调用微信的API地址获取openId和sessionkey信息然后前端页面通过点击授权按钮触（encrypdata、ivdata，sessionKey）调用后端接口进行解密获取授权用户信息

3.开发流程如下首先在配置文件里面配置appId和appSecret 如下图：

4.获取微信openId sessionKey工具类代码如下：


package com.longjin.wechat.controller;
 
import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONObject;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
 
/**
 * 请求微信小程序 api
 */
public class WeChatMiniClient {
 
    /**
     * 请求微信小程序api 获取 openId,session_key
     *
     * @param code      wx.login返回 code值
     * @param appId     小程序 appId
     * @param appSecret 小程序 appSecret
     * @return
     */
    public static JSONObject feighMini(String code, String appId, String appSecret) {
        //拼接url
        StringBuilder url = new StringBuilder("https://api.weixin.qq.com/sns/jscode2session?");
        url.append("appid=");//appId设置
        url.append(appId);
        url.append("&secret=");//secret设置
        url.append(appSecret);
        url.append("&js_code=");//code设置
        url.append(code);
        url.append("&grant_type=authorization_code"); //值固定
        JSONObject jsonObject = new JSONObject();
        try {
            HttpClient client = HttpClientBuilder.create().build();//构建一个Client
            HttpGet get = new HttpGet(url.toString());    //构建一个GET请求
            HttpResponse response = client.execute(get);//提交GET请求
            HttpEntity result = response.getEntity();//拿到返回的HttpResponse的"实体"
            String content = EntityUtils.toString(result);
            jsonObject = JSON.parseObject(content);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return jsonObject;
    }
}

5.调用工具类获取到sessionkey和openid放入redis中等前端点用户授权之后和encrypdata、ivdata一起传过来，注意这里不要直接把sessionkey直接放到sessionkey放到接口中返到前端，sessionkey属于私密信息我这里是保存到redis中代码如下：


public Map<String, Object> loginAuto(String code) throws Exception {
    Map<String, Object> map = new HashMap<>();
    //请求小程序api
    JSONObject jsonObject = WeChatMiniClient.feighMini(code, caseAppId, caseAppSecret);
    Map<String, Object> tempMap = AllJsonUtils.convertJson2Object(jsonObject, Map.class);
    //包含错误码
    if (tempMap.containsKey("errcode")) {
        String errCode = tempMap.get("errcode").toString();
        //错误 非法请求
        //系统返回msg,携带英文
        String sysMsg = tempMap.get("errmsg").toString();
        map.put("errorCode", errCode);
        map.put("errorMsg", MiniConstants.getMsg(errCode, sysMsg));
    } else if (tempMap.containsKey("session_key")) {
        //获取用户唯一标识
        String openId = tempMap.get("openid").toString();
        map.put("openId",openId);
            //将openId与sessionKey关联 放入缓存中
        redisUtil.setex(openId, tempMap.get("session_key").toString(), Contents.appRedisLoginTimeOut, Contents.userIndexdb);
    }
    return map;
}

6.点击授权获取手机号码代码如下：

/**
* <desc>
* 解密与微信绑定的手机号
* </desc>
*
* @param encrypdata 微信参数
* @param ivdata 微信参数
* @param sessionKey 会话密钥
* @return
* @createDate 2018/11/24
*/
@RequestMapping(path = "/getPhoneNum",method = RequestMethod.POST)
@ResponseBody
public MessageVO getPhoneNum(String encrypdata,String ivdata,String sessionKey){
try {
if(StringUtils.isEmpty(encrypdata) || StringUtils.isEmpty(ivdata) || StringUtils.isEmpty(sessionKey)){
return new MessageVO(BaseErrorCodeEnum.NOT_PARAM.getErrorCode());
}
byte[] encrypData = Base64.decode(encrypdata);
byte[] ivData = Base64.decode(ivdata);
byte[] sessionKeyByte = Base64.decode(sessionKey);
AlgorithmParameterSpec ivSpec = new IvParameterSpec(ivData);
Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
SecretKeySpec keySpec = new SecretKeySpec(sessionKeyByte, "AES");
cipher.init(Cipher.DECRYPT_MODE, keySpec, ivSpec);
//解析解密后的字符串
String phoneNum = new String(cipher.doFinal(encrypData),"UTF-8");

JSONObject jsonObjects = JSONObject.parseObject(json);

String phoneNumber = jsonObjects.getString("phoneNumber");//用户手机号

return new MessageVO(BaseErrorCodeEnum.SUCCESS.getErrorCode(),phoneNum);
}catch (Exception e){
throw new DataAccessException("【小程序_注册登录版块】解密与微信绑定的手机号失败",e);
}
}

7.以上就是获取授权之后的用户手机号码令附上项目中实际应用代码如下：


@Override
public ResultsCode saveUserInfo(GlobalUser globalUser){
    try {
        String sessionKey = "";
             sessionKey = redisUtil.get(globalUser.getOpenId(), Contents.userIndexdb);
             //sessionKey查询不到查数据库
        if(StringUtils.isBlank(sessionKey)){
            VipThirdAccountUser vipThirdAccountUser = vipThirdAccountUserDao.findByAccountId(globalUser.getOpenId());
             sessionKey = vipThirdAccountUser.getAccountKey();
        }
        byte[] encrypData = com.sun.org.apache.xerces.internal.impl.dv.util.Base64.decode(globalUser.getEncryptedData());
        byte[] ivData = com.sun.org.apache.xerces.internal.impl.dv.util.Base64.decode(globalUser.getIv());
        byte[] sessionKeyByte = Base64.decode(sessionKey);
        AlgorithmParameterSpec ivSpec = new IvParameterSpec(ivData);
        Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
        SecretKeySpec keySpec = new SecretKeySpec(sessionKeyByte, "AES");
        cipher.init(Cipher.DECRYPT_MODE, keySpec, ivSpec);
        //解析解密后的字符串
        String json = new String(cipher.doFinal(encrypData),"UTF-8");
        JSONObject jsonObjects = JSONObject.parseObject(json);
        String phoneNumber = jsonObjects.getString("phoneNumber");
        //通过openId查询
        VipThirdAccountUser vipThirdAccountUser = vipThirdAccountUserDao.findByAccountId(globalUser.getOpenId());
        Map<String,Object>   map = new HashMap<>();
        //没有对应数据 加入用户数据
        if (null == vipThirdAccountUser) {//新用户
            globalUser.setAccountId(globalUser.getOpenId());
            globalUser.setPhone(phoneNumber);
            globalUser.setAccountKey(sessionKey);
            addUserInfo(globalUser);
        } else {//老用户
            String username = vipThirdAccountUser.getUsername();
            GlobalUser byUserName = globalUserDao.findByUserName(username);
            if (null != byUserName) {
                doCommon(map, byUserName, globalUser.getOpenId());
               return ResultsCode.success(map);
            }
        }
    }catch (Exception e){
        return ResultsCode.Fail();
    }
    return ResultsCode.success();
}

    boolean loginExist = redisUtil.exists(SysStringUtils.md5(globalUser.getUsername() + "mini"), Contents.userIndexdb);
