背景：我们开发了一套授权的系统，通过米家App对自己选择的设备进行授权，就可以在其他app中获取这些授权设备的信息并且可以对其进行操作。 前提条件： 在获取授权之前，您需要：
- 在米家开放平台完成开发者资质认证
- 完成app应用申请并通过审核，并完善相关资料
- 下载一个米家App并注册一个属于自己的账号
compile(name:'authlib-release', ext:"aar")
IAuthMangerImpl.getInstance().init(AuthActivity.this);///初始化
3 发起授权IAuthMangerImpl.getInstance().callAuth（final Context context, final Bundle data, final int requestCode, IAuthResponse response）
requestCode对应的是要请求哪种授权
- 1)如果请求的是给设备进行授权则传入AuthCode.REQUEST_CODE_CALL_AUTH_FOR_DEVICE(设备授权之前，该小米账户需要已经绑定该设备)
Bundle data对应的是需要传入的参数
如果是设备授权的话，需要传入AuthConstants.EXTRA_APPLICATION_ID，，该参数需要到开放平台申请。
同时你还需要传入设备的id，AuthConstants.EXTRA_DEVICE_DID。
例如
Bundle bundle = new Bundle();
bundle.putString(AuthConstants.EXTRA_APPLICATION_ID, "app_id");
if (requestCode == AuthCode.REQUEST_CODE_CALL_AUTH_FOR_DEVICE){
bundle.putString(AuthConstants.EXTRA_DEVICE_DID,"device_id");
}
void onSuccess(int code, Bundle data);表示授权成功
void onFail(int code, Bundle data); 表示授权失败
其中code值的含义与下面的对应。 可以直接使用该AuthCode
public class AuthCode {
public static final int AUTH_SUCCESS = 100;//授权成功
public static final int PACKAGE_ERROR = -100;//包名错误
public static final int LACK_PARAMS_ERROR = -101;//缺少参数
public static final int GET_TOKEN_ERROR = -102;//获取token失败
public static final int AUTH_ERROR = -103;//授权失败
public static final int APP_ID_ERROR = -104;//appid有问题
public static final int APP_SIGN_ERROR = -105;//签名错误
public static final int AUTH_CANCEL = -106;///取消授权
public static final int REQUEST_AUTH_ERROR = -107;//请求授权失败
public static final int REQUEST_CODE_ERROR = -108;//请求的code错误
public static final int REQUSET_DID_ERROR = -109;///缺少did
public static final int REQUEST_CODE_CALL_AUTH_FOR_APP = 1;//请求app授权
public static final int REQUEST_CODE_CALL_AUTH_FOR_DEVICE = 2;//请求设备授权
}
而返回的data中，主要有下面四个值，注意判空使用
/返回值***/
public static final String EXTRA_TOKEN = "extra_token";
public static final String EXTRA_RESULT_CODE = "extra_result_code";
public static final String EXTRA_RESULT_MSG = "extra_result_msg";
public static final String EXTRA_USER_ID = "extra_user_id";
///一些请求和返回的key常量
public class AuthConstants {
// 请求参数
public static final String EXTRA_APPLICATION_ID = "extra_application_id";
public static final String EXTRA_PACKAGE_NAME = "extra_package_name";
public static final String EXTRA_APP_SIGN = "extra_app_sign";
public static final String EXTRA_DEVICE_DID = "device_id";
public static final int ACTIVITY_RESULT_FAIL = -2;
/**返回值*****/
public static final String EXTRA_TOKEN = "extra_token";
public static final String EXTRA_RESULT_CODE = "extra_result_code";
public static final String EXTRA_RESULT_MSG = "extra_result_msg";
public static final String EXTRA_USER_ID = "extra_user_id";
}
