[游戏开发]Cocos Creator Android集成Line登录

1. 集成Line登录

官网开发文档

1. 导入依赖

implementation 'com.linecorp:linesdk:5.0.1'

allprojects {
    repositories {
        jcenter() // line sdk仓库存放，没有就添加上
        ......
    }
}

android {
    defaultConfig {
        ......
        // 最小版本为17
        minSdkVersion 17 
        ......
    }

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

集成登录功能

先验证token是否有效，token有效则可以使用LineApiClient 获取token和userId；token无效需要跳转到Line app登录(如果没安装Line app则打开浏览器进行网页授权)
token有效状态下，用户信息都可以通过LineApiClient获取。
LineApiClient 的方法因为需要访问网络，所以都需要在子线程调用。

初始化

    //line初始化
    public  LineApiClient getLineApiClient(Context context) {
        if (lineApiClient == null) {
            synchronized (appActivity) {
                if (lineApiClient == null) {
                    LineApiClientBuilder apiClientBuilder = new LineApiClientBuilder(context,"你的id");
                    lineApiClient = apiClientBuilder.build();
                }
            }
        }
        return lineApiClient;
    }

登陆

 //line登陆
    public static void loginLine() {
        Log.e("TAG", "loginLine: 登陆");

        AsyncTask.THREAD_POOL_EXECUTOR.execute(() -> {
            try {
                // 检测token有效性
                if (appActivity.getLineApiClient(appActivity).verifyToken().isSuccess()) {
                    String accessToken = appActivity.getLineApiClient(appActivity).getCurrentAccessToken().getResponseData().getTokenString();
                    LineProfile profile = appActivity.getLineApiClient(appActivity).getProfile().getResponseData();
                    String userId = profile.getUserId();
                    Log.e("TAG", "loginLine: 登陆 accessToken:" +accessToken +"userId:"+userId  );

                    appActivity.runOnGLThread(new Runnable() {
                        @Override
                        public void run() {
                            Cocos2dxJavascriptJavaBridge.evalString("SystemBridge.OnLoginSuccess(\""+userId + "\",\"" + accessToken+"\")");
                        }
                    });
                    //TODO 获取token和userId，执行自己的登录业务逻辑
                    return;
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
            try{
                // 调起line app授权登录
                LineAuthenticationParams params = new LineAuthenticationParams.Builder().scopes(Arrays.asList(Scope.PROFILE)).build();
                Intent loginIntent = LineLoginApi.getLoginIntent(appActivity, "你的id", params);
                appActivity.startActivityForResult(loginIntent, 1000);
            } catch(Exception e) {
                e.printStackTrace();
            }
        });
    }

回调

  //line 回调
    private  void  handleLineInResult(LineLoginResult result) {
        Log.e("TAG", "handleLineInResult:result:" +result.getResponseCode());
        switch (result.getResponseCode()) {
            case SUCCESS:
                try {
                    String accessToken = result.getLineCredential().getAccessToken().getTokenString();
                    String userId = result.getLineProfile().getUserId();
                    String displayName = result.getLineProfile().getDisplayName();

                    Log.e("TAG", "handleLineInResult: 登陆 accessToken:" +accessToken +"userId:"+userId  );
                    //TODO 获取token和userId，执行自己的登录业务逻辑
                    appActivity.runOnGLThread(new Runnable() {
                        @Override
                        public void run() {
                            Cocos2dxJavascriptJavaBridge.evalString("SystemBridge.OnLoginSuccess(\""+userId + "\",\"" + accessToken+"\")");
                        }
                    });
                } catch (Exception e) {
                    e.printStackTrace();
                }
                break;
            case CANCEL:
                // Login CANCEL!
                break;
            default:
                // Login FAILED!
        }
    }

重载onActivityResult

  @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        SDKWrapper.getInstance().onActivityResult(requestCode, resultCode, data);
        if(requestCode == 1000){
            LineLoginResult result = LineLoginApi.getLoginResultFromIntent(data);
            handleLineInResult(result);
            }

    }

基本就这么多。
