現(xiàn)在極驗不支持flutter版本哀峻，創(chuàng)建了一個插件呈枉，將原聲的極驗可以可以用在flutter上面，支持自定義驗證堪侯，支持iOS嚎尤、Android雙端。

效果如下：

集成

dependencies:
  flutter_geetest:
    git: https://github.com/Joker-388/flutter-geetest.git

接口

   /// 極驗sdk版本
   static Future<String> skdVersion() async {
     final String version = await _channel.invokeMethod('getPlatformVersion');
     return version;
   }
  
    /// 啟動極驗 <br></br>
    /// String [api1]: api1,SDK代處理的第一次驗證接口 <br></br>
    /// String [api2]: api2,SDK代處理的第二次驗證接口 <br></br>
    /// String [gt]: gt伍宦，自行處理api1獲取的參數(shù) <br></br>
    /// String [challenge]: challenge芽死，自行處理api1獲取的參數(shù) <br></br>
    /// String [success]: success，自行處理api1獲取的參數(shù) <br></br>
    /// <br></br>
    /// {"msg":"xxxx", data:{"xxx":"xxx"}};
  
    static Future<Map<String, dynamic>> launchGeetest({String api1 = "", String api2 = "", String gt = "", String challenge = "", int success = -1}) async {
  
      var result = await _channel.invokeMethod('launchGeetest', {
        'api1': api1,
        'api2': api2,
        'gt': gt,
        'challenge': challenge,
        'success': success,
      });
      return json.decode(result);
    }
  

獲取極驗sdk版本

var version = await FlutterGeetest.skdVersion();
print("Geetest version $version");

使用極驗?zāi)J驗證

  /// api1+api2
  void _launchGeetest3() {
    FlutterGeetest.launchGeetest(
      api1: 'https://www.geetest.com/demo/gt/register-slide',
      api2: 'https://www.geetest.com/demo/gt/validate-slide',
    ).then((data) {
      print('Flutter_GeetestPlugin: data====>$data');
      if (data["data"] == null) {
        String errormsg = data["msg"];
        _showSnackbarMsg('$errormsg');
        return;
      }
      var result = data["data"];
      _showSnackbarMsg('$result');
    });
  }

自定義 注冊步驟次洼，使用默認二次驗證

  /// api1結(jié)果參數(shù)+api2
  void _launchGeetest4() {
    api1().then((data){
      FlutterGeetest.launchGeetest(
        gt: data['gt'],
        challenge: data['challenge'],
        success: data['success'],
        api2: 'https://www.geetest.com/demo/gt/validate-slide',
      ).then((data) {
        print('Flutter_GeetestPlugin: data====>$data');
        if (data["data"] == null) {
          String errormsg = data["msg"];
          _showSnackbarMsg('$errormsg');
          return;
        }
        var result = data["data"];
        _showSnackbarMsg('$result');
      });
    });
  }

自定義 二次驗證关贵，使用默認注冊步驟

  /// 僅api1 , 返回結(jié)果自行進行二次接口校驗
  void _launchGeetest1() {
    FlutterGeetest.launchGeetest(
      api1: 'https://www.geetest.com/demo/gt/register-slide',
    ).then((data) {
      print('Flutter_GeetestPlugin: data====>$data');
      if (data["data"] == null) {
        String errormsg = data["msg"];
        _showSnackbarMsg('$errormsg');
        return;
      }
      api2(data["data"]).then((data){
        print("api2: $data");
        _showSnackbarMsg('$data');
      });
    });
  }

自定義 注冊 和 二次驗證

  /// 僅api1結(jié)果參數(shù)(gt,challenge,success),參數(shù)來自于自行接口獲取
  void _launchGeetest2() {
    api1().then((data){
      print("!!!!! $data");
      FlutterGeetest.launchGeetest(
        gt: data['gt'],
        challenge: data['challenge'],
        success: data['success'],
      ).then((data) {
        print('Flutter_GeetestPlugin: data====>$data');
        if (data["data"] == null) {
          String errormsg = data["msg"];
          _showSnackbarMsg('$errormsg');
          return;
        }
        api2(data["data"]).then((data){
          print("api2: $data");
          _showSnackbarMsg('$data');
        });
      });
    });
  }
