通过wx.getUserInfo获取用户的openId 和unionId，需要对接口返回的加密数据( encryptedData )进行对称解密。
/**
* 功能描述: <br>
* 〈功能详细描述〉

*@paramargs
*@see[相关类/方法](可逗穗兄选)

publicstaticvoidmain(String[] args){
String encryptedData ="********......*******"
String sessionKey ="********......*******"
String iv ="9btKSYjvtGMGpknPpjS2Ag=="
JSONObject jsonObject = getUserInfo(encryptedData, sessionKey, iv)
System.out.println(jsonObject.getString("unionId"))
System.out.println(jsonObject.toJSONString())
}
结果运行报错：
javax.crypto.BadPaddingException: pad block corrupted

查询原因，有可能是我族拦的wx.login在wx.getUserInfo之后调的原因，细究一下
我们通过wx.login获得用户授权码code，接下来我们用code以及appid和appSecret请求微信
https://api.weixin.qq.com/sns/jscode2session?appid=APPID&secret=SECRET&js_code=JSCODE&grant_type=authorization_code
获取session_key，而sessionKey又是解密encryptedData的密钥，所以一旦我们的wx.login在wx.getUserInfo之后获取，我们redis中存储的sessionKey绝对不是当前获取encryptedData的密钥。所以更改小程序请求顺序，每次请求wx.getUserInfo之前先请求wx.login，同时生成sessionKey放入缓存。而后需要解密的时候就可以正常解密了
特别注意： 让前端看一下你的请求顺序山袭是不是错了
