- 当前 Bug 的表现（可附上截图）

有时候点击获取手机号按钮一次不管用，需要多次点击才可以！！！！！！！

1、偶尔点击无响应

点击获取手机号按钮

<button style="display: inline-block;border-radius: 50px;background: #ebc64b;padding: 15px 25px;box-shadow: 4px 7px 7px rgba(164, 144, 85, .3);" open-type="getPhoneNumber" bindgetphonenumber="getPhoneNumber">解锁我的测试报告</button>

没有调用相关方法

getPhoneNumber: function (e) {

wx.login({

success: function (r) {

console.log(e.detail.errMsg);

console.log(e.detail.iv);

console.log(e.detail.encryptedData);

console.log(r.code);

2、有时点击了，也响应了，但是没有传上来参数encryptedData和iv

3、有时候数据传上来了，但是，解密出错

有两组数据，第一次点击获取失败，紧接着再次点击调用成功

result = AesCbcUtil.decrypt("p3QhMucG/aQijjxCRcK4eIXHQINJGW15uBxG3DdmvRRDchxLIrnc63fs06Q4i98RqiPyJH0jlepTUrh/LhzLEARXkLrTT8Q0H8HQC3LpwusYYfiWXcQMayGOoiAUiPqCU6Y+pdrwuPSCJktLU8d/A0xneqnWWqrNPmjqgtoyP5YOtLbuYIeTJ8VTMF5AkWnA5NkT9AHSDMMIM47nCWoxTw==",

System.out.print("\r\n ----------------- decrypt result \r\n"+result);

result = AesCbcUtil.decrypt("V4svsc89WcGrClnTgQdVYsWJqG4m48Fus1BkyAF5YtlIM93E86Y6QiF1wSSW35Iizi2ewMzvG5al3qlCrExjynHZRyRmqb0ajsf9HvFQqkPBxOA0hixBnUo4jPfyiNluemL9ch7J0aeswB8KS/EgnLmXE+Rt17Iev22p0i9uXCk2gM3/Krbc8DQ4/fF4rhhLP5+4/kLjr2xdLRqmvdUmzQ==",

System.out.print("\r\n ----------------- decrypt result \r\n"+result);

    public static String decrypt(String data, String key, String iv) throws Exception {

//      initialize();

byte[] encrypData = Base64.decodeBase64(data);

byte[] ivData = Base64.decodeBase64(iv);

byte[] sessionKey = Base64.decodeBase64(key);

String str = "";

try {

// str = decrypt(sessionKey, ivData, encrypData);

AlgorithmParameterSpec ivSpec = new IvParameterSpec(ivData);

Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");

SecretKeySpec keySpec = new SecretKeySpec(sessionKey, "AES");

cipher.init(Cipher.DECRYPT_MODE, keySpec, ivSpec);

// 解析解密后的字符串

str= new String(cipher.doFinal(encrypData), "UTF-8");

第一组数据调用失败
