智能摄像头扫码配网

扫码配网指的是设备扫描 App 生成的二维码，二维码包含 Wi-Fi 信息和 token，设备扫描成功后，主动连接到路由器去云端进行激活的配网方式。主要针对具有摄像头扫描功能和 Wi-Fi 模组的设备，所以通常是智能摄像头或是带有摄像头的设备（如可视门铃）支持二维码配网。

配网流程

注册配网类型

基座初始化时，需要注册一下配网的类型，扫码配网模式对应为 ThingSmartActivatorTypeQRCodeModel。

接口说明

/// Initialize network configuration types
/// @param typeList Network configuration types
- (void)registerWithActivatorList:(NSArray<ThingSmartActivatorTypeModel *>*)typeList;

参数说明

参数	说明
typeList	配网类型列表

查询 Token

使用涂鸦 SDK 获取配网 Token，然后进行配网。Token 的有效期为 10 分钟，且配置成功后就会失效。再次配网时，需要重新查询 Token。

接口说明

- (void)getTokenWithHomeId:(long long)homeId
                   success:(ThingSuccessString)success
                   failure:(ThingFailureError)failure;

参数说明

参数	说明
homeId	设备将要绑定到的家庭的 ID
success	成功回调，返回配网 Token
failure	失败回调，返回失败原因

二维码字符串

获取到配网 Token 后，还需要有期望设备连接的 Wi-Fi 的 ssid 和密码，通过下面的方式拼接成字符串，然后根据该字符串生成一个二维码图片。

Objective-C

NSDictionary *dictionary = @{
@"s": self.ssid,
@"p": self.pwd,
@"t": self.token
};
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dictionary options:0 error:nil];
self.wifiJsonStr = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];

Swift

let dictionary = [
    "s": self.ssid,
    "p": self.pwd,
    "t": self.token
]
let jsonData = JSONSerialization.data(withJSONObject: dictionary, options: JSONSerialization.WritingOptions.Element)
self.wifiJsonStr = String(data: jsonData, encoding: String.Encoding.utf8)

开始搜索

开始搜索时，需要传入已注册的 typeList。

接口说明

/// Start searching
/// @param typeList Network configuration types
- (void)startSearch:(NSArray <ThingSmartActivatorTypeModel *>*)typeList;

参数说明

参数	说明
typeList	配网类型列表

停止搜索

接口说明

/// Stop searching
/// @param typeList Network configuration types
/// @param clearCache Whether to clear the cache
- (void)stopSearch:(NSArray <ThingSmartActivatorTypeModel *>*)typeList clearCache:(BOOL)clearCache;

参数说明

参数	说明
typeList	配网类型列表
clearCache	是否清空当前搜索设备缓存

搜索设备回调

设备配网成功之后，会通过搜索回调返回设备信息。如果失败，则会返回对应的失败信息。

发现设备回调

接口说明

/// Device search callback
/// @param service Search instance
/// @param type Network configuration type
/// @param device Discovered device
/// @param errorModel Error callback
- (void)activatorService:(id<ThingSmartActivatorSearchProtocol>)service
            activatorType:(ThingSmartActivatorTypeModel *)type
             didFindDevice:(nullable ThingSmartActivatorDeviceModel *)device
                     error:(nullable ThingSmartActivatorErrorModel *)errorModel;

参数说明

参数	说明
service	配网服务
type	配网类型，此处返回 ThingSmartActivatorTypeQRCodeModel
device	发现设备，返回此次配网的设备模型，失败时返回 nil
errorModel	如果配网失败或者超时，返回此模型，成功时返回 nil

设备信息更新回调

接口说明

/// Device information update or device rediscovered on a different channel
/// @param service Search instance
/// @param type Network configuration type
/// @param device Device model
- (void)activatorService:(id<ThingSmartActivatorSearchProtocol>)service
            activatorType:(ThingSmartActivatorTypeModel *)type
           didUpdateDevice:(ThingSmartActivatorDeviceModel *)device;

参数说明

参数	说明
service	配网服务
type	配网类型，此处返回 ThingSmartActivatorTypeQRCodeModel
device	返回变化的设备信息

错误码说明

配网失败或者配网超时的情况下，会返回 ThingSmartActivatorErrorModel。

@interface ThingSmartActivatorErrorModel : NSObject
@property (nonatomic, strong) ThingSmartActivatorDeviceModel *deviceModel;
@property (nonatomic) NSError *error;
@end

其中 error 对应的错误码，定义在 ThingSmartActivatorDiscoveryError 中。下表展示了常见错误与说明。

错误码	配网错误
ThingSmartActivatorDiscoveryErrorTimeout	配网超时。
ThingSmartActivatorDiscoveryErrorDeviceAlreadyBound	设备强绑定错误。该设备已经被用户绑定，无法被第二个用户绑定，需要第一个用户解绑才能完成配网操作。
ThingSmartActivatorDiscoveryErrorAPPUnsupportProduct	配网账号的 App 和产品没有绑定关系。
ThingSmartActivatorDiscoveryErrorTokenExpired	Token 失效。
ThingSmartActivatorDiscoveryErrorGuestNotSupportStrongBind	游客模式无法对强绑定设备进行配网。
ThingSmartActivatorDiscoveryErrorRemoteApiParamIllegal	接口参数不合法。
