ユーザーの Facebook 受信トレイからメッセージを読み取ろうとしていますが、アクセスを拒否するエラーが発生しています。これは私のコードです:
ACAccountStore *accountStore = [[ACAccountStore alloc] init];
ACAccountType *fbAccountType = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];
NSDictionary *options = @{
ACFacebookAppIdKey : FacebookAppKey,
ACFacebookPermissionsKey : FacebookPermissionsArray
};
[accountStore requestAccessToAccountsWithType:fbAccountType options:options completion:^(BOOL granted, NSError *error)
{
if (error || !granted) {
return;
}
NSArray *accounts = [accountStore accountsWithAccountType:fbAccountType];
if (accounts.count == 0) {
return;
}
ACAccount *facebookAccount = [accounts lastObject];
NSURL *inboxURL = [NSURL URLWithString:@"https://graph.facebook.com/me/inbox"];
NSMutableDictionary *parameters = [[NSMutableDictionary alloc] init];
SLRequest *facebookInfoRequest = [SLRequest requestForServiceType:SLServiceTypeFacebook
requestMethod:SLRequestMethodGET
URL:inboxURL
parameters:parameters];
[facebookInfoRequest setAccount:facebookAccount];
[facebookInfoRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
NSLog(@"response data: %i, url response: %@, error: %@", responseData.length, urlResponse, error);
}];
}];
これに対する URL 応答は次のとおりです。
<NSHTTPURLResponse: 0xcb5fa10> { URL: https://graph.facebook.com/me/inbox?access_token=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX } { status code: 400, headers {
"Access-Control-Allow-Origin" = "*";
"Cache-Control" = "no-store";
Connection = "keep-alive";
"Content-Length" = 194;
"Content-Type" = "application/json; charset=UTF-8";
Date = "Tue, 18 Feb 2014 15:29:36 GMT";
Expires = "Sat, 01 Jan 2000 00:00:00 GMT";
Pragma = "no-cache";
"Www-Authenticate" = "OAuth \"Facebook Platform\" \"invalid_token\" \"Error validating access token: Session has expired on Feb 13, 2014 6:17am. The current time is Feb 18, 2014 7:29am.\"";
"X-FB-Debug" = "XXXXXXXXXXXXXXXX/Y+K0w=";
"X-FB-Rev" = XXXXXXXX;
} }
なぜこの問題が発生したのかわかりません。ここで何が間違っているのでしょうか?
