iOS：四方請求失敗

Question

我最近被分配到foursquare工作。我有一個需要驗證並訪問foursquare環境的應用程序。我無法訪問以下代碼來訪問checkins。我已經成功進行了身份驗證，但事實是，當我進行了請求檢查時，會出現一個errorType invalid_auth代碼401。我只是不知道這有什麼問題。

這是我的完整代碼;我正在使用fsq包裝我在github中找到：

#import "FSQViewController.h" 

#define kClientID  @"XXXXXXXXXXXXXXXXXXXXXXX" 
#define kCallbackURL @"invitation://foursquare" 

@interface FSQViewController() 
@property(nonatomic,readwrite,strong) BZFoursquare *foursquare; 
@property(nonatomic,strong) BZFoursquareRequest *request; 
@property(nonatomic,copy) NSDictionary *meta; 
@property(nonatomic,copy) NSArray *notifications; 
@property(nonatomic,copy) NSDictionary *response; 
@end 


@implementation FSQViewController 

@synthesize foursquare = foursquare_; 
@synthesize request = request_; 
@synthesize meta = meta_; 
@synthesize notifications = notifications_; 
@synthesize response = response_;

你能幫助我嗎？任何幫助將高度讚賞。

Answer 1

https://developer.foursquare.com/overview/responses

401（未授權）基於OAuth的認證令牌提供，但無效。

你可能會損壞你的oauth標記嗎？

Answer 2

我使用下面&它的代碼爲我工作：

NSDictionary *parameters = @{@"venueId": @"4a0c6465f964a5202a751fe3", @"broadcast": @"public",@"oauth_token":kClientID};
