使用方式

    2. //import 'package:captcha/captcha/click_word_captcha.dart';
    3. static void loadingClickWord(BuildContext context, {barrierDismissible = true}) {
    4.   showDialog<Null>(
    5.     context: context,
    6.     barrierDismissible: barrierDismissible,
    7.     builder: (BuildContext context) {
    8.       return ClickWordCaptcha(
    9.         onSuccess: (v){//成功回调（回调为加密后内容，依据项目而定）
    11.         },
    13.         },
    14.       );
    15.     },
    16.   );
    17. }
    19. //滑动拼图
    20. //import 'package:captcha/captcha/block_puzzle_captcha.dart';
    21. static void loadingBlockPuzzle(BuildContext context, {barrierDismissible = true}) {
    22.   showDialog<Null>(
    23.     context: context,
    24.     barrierDismissible: barrierDismissible,
    25.     builder: (BuildContext context) {
    26.       return BlockPuzzleCaptchaPage(
    27.         onSuccess: (v){ //成功回调（回调为加密后内容，依据项目而定）
    29.         onFail: (){
    31.         },
    32.       );
    33.     },
    34.   );

    请求处理

    1. {
    2.   "pointJson": cryptedStr,
    3.   "captchaType": "clickWord",
    4.   "token": _clickWordCaptchaModel.token
    5. }

    二次校验传出的参数

    1. //如果不加密  将  token  和 坐标序列化 通过  --- 链接成字符串
    2. var captchaVerification = "$captchaToken---$pointStr";
    3. if(!ObjectUtils.isEmpty(secretKey)){
    4.   //如果加密  将  token  和 坐标序列化 通过  --- 链接成字符串 进行加密  加密密钥为 _clickWordCaptchaModel.secretKey
    5.   captchaVerification = EncryptUtil.aesEncode(key: secretKey, content: captchaVerification);
