小程序第一次授权未获取openid，再次授权时，在AES解密时就成乱码了，调的方法是weixin-java-miniapp-4.4.0包下，WxMaCryptUtils.decrypt(sessionKey, encryptedData, ivStr )。导致后面解析json时报如下错误：Expected BEGIN_OBJECT but was STRING at line 1 column 1 path $

小程序登录成功后校验授权时，无法获取openid，调的微信接口为/api/auth/wxapp/auth；入参：{"encryptedData":"已隐藏","code":"已隐藏","iv":"已隐藏","spread":""}
