我正在尝试在我的应用中实现Facebook登录并且它正在运行(我正在获取访问令牌),但每当我尝试发出图形请求时,我都会收到以下消息:我需要一个有效访问权限令牌,以便向图API发出请求:
Error Domain=facebookErrDomain Code=10000 "The operation couldn’t be completed. (facebookErrDomain error 10000.)" UserInfo=0x6a99fa0 {
error=<CFBasicHash 0x6a99050 [0x1582b48]>{
type = mutable dict, count = 3,
entries =>
2 : <CFString 0x6a99340 [0x1582b48]>{contents = "type"} = <CFString 0x6a994d0 [0x1582b48]>{contents = "OAuthException"}
3 : <CFString 0x6a99470 [0x1582b48]>{contents = "message"} = <CFString 0x6a993d0 [0x1582b48]>{contents = "An active access token must be used to query information about the current user."}
6 : <CFString 0x6a52270 [0x1582b48]>{contents = "code"} = 2500
}
}
发出请求的代码看起来像那样(也许我需要在这里添加访问令牌?):
[facebook requestWithGraphPath:@"me" andDelegate:self];
现在我知道访问令牌是正常的,因为在init
方法中我调用了一个方法,在必要时更新它:
[facebook extendAccessTokenIfNeeded];
我还在实现extendAccessTokenIfNeeded
:
-(void)fbDidExtendToken:(NSString *)accessToken expiresAt:(NSDate *)expiresAt {
NSLog(@"token extended"); //This NSLog hasn't been called, so I know the extending access token method wasn't fired...
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:accessToken forKey:@"FBAccessTokenKey"];
[defaults setObject:expiresAt forKey:@"FBExpirationDateKey"];
[defaults synchronize];
}
现在我在这里失踪了什么?我是否需要将访问令牌添加到图形API请求中?如果是这样,怎么样?
顺便说一句,我也知道,如果我向公共路径发出图形请求,它就能完美地运行。答案 0 :(得分:0)
刚遇到同样的问题,我不知道为什么,但原生的facebook SDK似乎没有用他们的令牌代替GET请求。可能是你麻烦了吗?我用了以下解决方法:
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
_facebook.accessToken, @"access_token",
nil];
[_facebook requestWithGraphPath:@"me/music"
andParams:params
andHttpMethod:@"GET"
andDelegate:self];
UPD 的答案适用于[_facebook requestWithGraphPath:@"me" andParams:params andHttpMethod:@"GET" andDelegate:self]
,但不适用于[facebook requestWithGraphPath:@"me" andDelegate:self];
