在iOS中使用Oauth获得Fitbit的授权

我希望为Fitbit实施OAuth身份validation，以便在我的iOS应用中从FitBit Api读取数据。 我注册了我的应用程序，我得到了clientId和客户端的秘密。 我从过去2天开始搜索教程库。 我对此一无所知。 请建议我。

Answer 1

注 – 根据https://dev.fitbit.com/docs/oauth2/

• 应用程序应在2016年3月14日之前升级到OAuth 2.0
• 使用safari或SFSafariViewController打开授权页面

解决方案从这里开始

请替换CLIENT_ID，REDIRECT_URI和其他文本以更正信息

Point1-

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"https://www.fitbit.com/oauth2/authorize?response_type=code&client_id=CLIENT_ID&redirect_uri=REDIRECT_URI&scope=activity%20nutrition%20heartrate%20location%20nutrition%20profile%20settings%20sleep%20social%20weight"]]; 

提供适当的方案url，以便在成功登录后，您将被重定向到您的应用程序。 在openURL方法中，您将获得OAUTHCODE

Point2-

现在使用此OAUTHCODE获取OAUTHTOKEN

 -(void)toGetRequestToken:(id)sender { NSString *strCode = [[NSUserDefaults standardUserDefaults] valueForKey:@"auth_code"]; NSURL *baseURL = [NSURL URLWithString:@"https://www.fitbit.com/oauth2/authorize"]; AFOAuth2Manager *OAuth2Manager = [AFOAuth2Manager managerWithBaseURL:baseURL clientID:CLIENT_ID secret:CONSUMER_SECRET]; OAuth2Manager.responseSerializer.acceptableContentTypes = [OAuth2Manager.responseSerializer.acceptableContentTypes setByAddingObject:@"text/html"]; NSDictionary *dict = @{@"client_id":CLIENT_ID, @"grant_type":@"authorization_code",@"redirect_uri":@"Pro-Fit://fitbit",@"code":strCode}; [OAuth2Manager authenticateUsingOAuthWithURLString:@"https://api.fitbit.com/oauth2/token" parameters:dict success:^(AFOAuthCredential *credential) { // you can save this credential object for further use // inside it you can find access token also NSLog(@"Token: %@", credential.accessToken); } failure:^(NSError *error) { NSLog(@"Error: %@", error); }]; } 

Point3-

现在你可以点击其他FitBit请求，比如“UserProfile” –

 -(void)getFitbitUserProfile:(AFOAuthCredential*)credential{ NSURL *baseURL = [NSURL URLWithString:@"https://www.fitbit.com/oauth2/authorize"]; AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc] initWithBaseURL:baseURL]; [manager.requestSerializer setAuthorizationHeaderFieldWithCredential:credential]; manager.responseSerializer = [AFHTTPResponseSerializer serializer]; [manager GET:@"https://api.fitbit.com/1/user/-/profile.json" parameters:nil progress:^(NSProgress * _Nonnull downloadProgress) { } success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) { NSDictionary *dictResponse = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableContainers error:nil]; NSDictionary *userDict =[dictResponse valueForKey:@"user"]; NSLog(@"Success: %@", userDict); } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) { NSLog(@"Failure: %@", error); }]; }
