Question

我想为Fitbit实施OAuth身份验证，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和其他文字以更正信息

<强> 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"]];

提供适当的方案网址，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

<强> 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);
    }];
}

在iOS中使用Oauth获得Fitbit的授权
