小程序渲染一半数据_微信小程序用户数据解密算法Java版

打开官方文档&＃xff0c;开心~ 腾讯爸爸竟然给提供了解密算法

然而我下载解压后人傻了

可能鹅厂没养Java程序猿吧

那就看这C&＃43;&＃43;改造吧

public class AnthCodeVerify { private final static String cipherString &＃61; "AES/CBC/PKCS5Padding"; public static JSONObject decrypt(String encryptedData, String iv, String sessionKey) throws Exception { String jsonStr; try { BASE64Decoder base64Decoder &＃61; new BASE64Decoder();            byte[] encryptedByte &＃61; base64Decoder.decodeBuffer(encryptedData); byte[] sessionKeyByte &＃61; base64Decoder.decodeBuffer(sessionKey); byte[] ivByte &＃61; base64Decoder.decodeBuffer(iv); SecretKeySpec skeySpec &＃61; new SecretKeySpec(sessionKeyByte, "AES"); Cipher cipher &＃61; Cipher.getInstance(cipherString); IvParameterSpec ivParameterSpec &＃61; new IvParameterSpec(ivByte); cipher.init(Cipher.DECRYPT_MODE, skeySpec, ivParameterSpec); byte[] original &＃61; cipher.doFinal(encryptedByte); jsonStr &＃61; new String(original); } catch (Exception ex) { throw new Exception("Illegal Buffer"); } JSONObject jsonObject &＃61; new JSONObject(jsonStr); return jsonObject; }}

解密后的数据格式如下&＃xff1a;

{ "openId": "OPENID", "nickName": "NICKNAME", "gender": GENDER, "city": "CITY", "province": "PROVINCE", "country": "COUNTRY", "avatarUrl": "AVATARURL", "unionId": "UNIONID", "watermark": { "appid":"APPID", "timestamp":TIMESTAMP }}

Q1: 为什么解密后的数据中没有unionId&＃xff1f;需要小程序管理员将小程序绑在微信开放平台
