ios - 在 iOS 中使用 Oauth 从 Fitbit 获得授权

Question

我想为 Fitbit 实施 OAuth 身份验证，以在我的 iOS 应用程序中从 FitBit Api 读取数据。我注册了我的应用程序，并获得了 clientId 和客户端密码。从过去 2 天开始，我一直在搜索教程、库。我对此一无所知。请给我建议。

Answer 1

注意- 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

点1-

[[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"]];

提供正确的方案 url，以便在成功登录后您将被重定向到您的应用程序。在 openURL 方法中你会得到一个 OAUTHCODE

点2-

现在通过使用此 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);
   }];
}

点3-

现在您可以点击其他 FitBit 请求，例如“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);
    }];
}
