我想获取 facebook 好友的个人资料图片。我还为其提供了 access_token。
我在网上搜索了很多，但没有找到任何好的解决方案。
我的代码如下:
- (IBAction)advancedButtonPressed:(id)sender {
self.accountStore = [[ACAccountStore alloc]init];
ACAccountType *FBaccountType= [self.accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];
//NSString *key = @"xxxxxx";
NSString *key = @"xxxxxx";
NSDictionary *dictFB = [NSDictionary dictionaryWithObjectsAndKeys:key,ACFacebookAppIdKey,@[@"email"],ACFacebookPermissionsKey, nil];
[self.accountStore requestAccessToAccountsWithType:FBaccountType options:dictFB completion:
^(BOOL granted, NSError *e) {
if (granted) {
NSArray *accounts = [self.accountStore accountsWithAccountType:FBaccountType];
//it will always be the last object with single sign on
self.facebookAccount = [accounts lastObject];
NSLog(@"facebook account =%@",self.facebookAccount);
ACAccountCredential *fbCredential = [self.facebookAccount credential];
accessToken = [fbCredential oauthToken];
NSLog(@"Facebook Access Token: %@", accessToken);
[self get];
} else {
//Fail gracefully...
NSLog(@"error getting permission %@",e);
}
}];
}
-(void)fr
{
NSURL *requestURL = [NSURL URLWithString:@"https://graph.facebook.com/me/friends?fields=id,name,picture,first_name,last_name,gender&access_token=BAAFcRQZCZAUeUBAICacM2q1V5UzRHee6xHGnbEdu19v6CZBIEDJmTwHBKtMZBwtVuFiEeuXqt4yKeSkeI17QZBGaZCeszBfOKdbZAfR4E9RN2nFqHalKPXZBga96WQCU8CSNG4ZCJCK1V7JIbqZAPRgNl6mjjO4Ns1CEaLpbXUYtum1CXbNqTtT82YpVVKoZCmMEBpqHfwYMx1OKu9RZBsjPZA6DlhKA1uGyU32EGJ8QOQZASJVQZDZD"];
SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeFacebook
requestMethod:SLRequestMethodGET
URL:requestURL
parameters:nil];
request.account = self.facebookAccount;
[request performRequestWithHandler:^(NSData *data,
NSHTTPURLResponse *response,
NSError *error) {
if(!error)
{
list =[NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
NSLog(@"Dictionary contains data: %@", list );
if([list objectForKey:@"error"]!=nil)
{
[self attemptRenewCredentials];
}
dispatch_async(dispatch_get_main_queue(),^{
nameLabel.text = [list objectForKey:@"username"];
});
}
else{
//handle error gracefully
NSLog(@"error from get%@",error);
//attempt to revalidate credentials
}
}];
}
但我总是得到这样的错误:
error = {
code = 190;
message = "Malformed access token BAAFcRQZCZAUeUBAICacM2q1V5UzRHee6xHGnbEdu19v6CZBIEDJmTwHBKtMZBwtVuFiEeuXqt4yKeSkeI17QZBGaZCeszBfOKdbZAfR4E9RN2nFqHalKPXZBga96WQCU8CSNG4ZCJCK1V7JIbqZAPRgNl6mjjO4Ns1CEaLpbXUYtum1CXbNqTtT82YpVVKoZCmMEBpqHfwYMx1OKu9RZBsjPZA6DlhKA1uGyU32EGJ8QOQZASJVQZDZD?access_token=BAAFcRQZCZAUeUBAHBZBSdTL9wWFDOVthxj78bBJlrNEkPiKHdxZA1HaRmO9dtBTJdsZCtZCu2vaE5ByZAdK7Ox30BpIR0KTg0ZC6pi1IOE0KnZCZBSxqbycG0C6Ws5Ct4ferL3G0VU1wIfDypKekFM3zB4r5gAiUREQ66Yuz2Fu2mp5NGqZCBE1p357H41P2lKOAQN9EZAmu4q3SRtjMuVIw4dtdC00l4RhMuDWTOIUQlO54bgZDZD";
type = OAuthException;
};
}
我无法解决这个问题。帮帮我!
最佳答案
如果您使用的是 SLRequest，它会自动为您附加访问 token ，并且您也不应该在 URL 本身中包含任何请求参数。相反，你应该这样做:
NSURL *requestURL = [NSURL URLWithString:@"https://graph.facebook.com/me/friends"];
SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeFacebook
requestMethod:SLRequestMethodGET
URL:requestURL
parameters:@{@"fields":@"id,name,picture,first_name,last_name,gender"}];
