无法使用 OAuth 2.0 从 Facebook 获取用户信息

发布于 2024-09-18 13:04:28 字数 454 浏览 8 评论 0原文

用户登录后，我就使用以下代码检索用户信息：

[_facebook requestWithGraphPath:@"me" andDelegate:self];

它在前几次有效，但最终返回了错误。我认为这是一个会话问题，因为我的权限有“offline_access”。我从 Facebook 注销并从干净的构建中再次编译，但它仍然返回此错误：

错误域=facebookErrDomain代码=10000 UserInfo=0x54a2930“操作无法完成。（facebookErrDomain错误10000。）”

我假设我的访问令牌有效，因为我可以发帖。我的假设正确吗？

我还注意到，每当我登录时，如果我允许我的应用程序访问我的用户信息，Facebook 不会重定向我来请求许可。

谁能告诉我出了什么问题吗？

原文

As soon as the user is logged in, I retrieve the user info using this code:

[_facebook requestWithGraphPath:@"me" andDelegate:self];

It worked for the first few times, but it eventually returned an error. I thought it was a session thing since I have "offline_access" on my permissions. I logged out from Facebook and compiled again from a clean build and it still returns this error:

Error Domain=facebookErrDomain Code=10000 UserInfo=0x54a2930 "Operation could not be completed. (facebookErrDomain error 10000.)"

I'm assuming my access token is valid since I can do posting. Am I right to assume that?

I also noticed that whenever I log in, Facebook doesn't redirect me to ask permission if I allow my app to access my user info.

Can anyone tell me what's wrong?

授权命令的答案似乎不同。现在，不像以前那样没有有效期了。我尝试强制 isSessionValid 返回 TRUE，并且它有效。

isSessionValid 检查 accessToken 和过期日期。由于没有到期日期，该函数返回 FALSE。

不知道这是 Facebook 的临时修改还是最终修改。在这种情况下，我认为 SDK 必须修复。新的调用必须检索expirationDate。

这是我使用过的临时修复。您可以在 FBLoginDialog.m 中的第 46 行找到此方法。

- (void) dialogDidSucceed:(NSURL*)url {
  NSString *q = [url absoluteString];
  NSString *token = [self getStringFromUrl:q needle:@"access_token="];
  NSDate *expirationDate = [NSDate distantFuture];

  if ((token == (NSString *) [NSNull null]) || (token.length ==0)) {
    [self dialogDidCancel:url];
    [self dismissWithSuccess:NO animated:YES];
  } else {
    if ([_loginDelegate respondsToSelector:@selector(fbDialogLogin:expirationDate:)]) {
      [_loginDelegate fbDialogLogin:token expirationDate:expirationDate];
    }
    [self dismissWithSuccess:YES animated:YES];
  }
}

是否每个遇到此问题的人都请求离线访问权限？这是我看到过期日期未发送的唯一原因。也许尝试不请求offline_access 权限。

Here's a temporary fix I've used. You can find this method line 46 in FBLoginDialog.m

- (void) dialogDidSucceed:(NSURL*)url {
  NSString *q = [url absoluteString];
  NSString *token = [self getStringFromUrl:q needle:@"access_token="];
  NSDate *expirationDate = [NSDate distantFuture];

  if ((token == (NSString *) [NSNull null]) || (token.length ==0)) {
    [self dialogDidCancel:url];
    [self dismissWithSuccess:NO animated:YES];
  } else {
    if ([_loginDelegate respondsToSelector:@selector(fbDialogLogin:expirationDate:)]) {
      [_loginDelegate fbDialogLogin:token expirationDate:expirationDate];
    }
    [self dismissWithSuccess:YES animated:YES];
  }
}

Does everyone with this issue request the offline_access permission? It's the only reason I can see an expiration date not being sent. Maybe try not requestion the offline_access permission.

我也遇到过同样的问题。我检查了我的隐私设置、权限、其他方法等...，但我无法解决它。
很多网站都说“检查访问offline_access/read_stream/publish_stream的权限”，我认为这些也很重要，但我无法修复它。

然后我终于找到了以下解决方案，效果很好。

您应该在“Facebook.m”文件上将“safariAuth:YES”更改为“safariAuth:NO”。

- (void)authorize:(NSArray *)permissions
         delegate:(id<FBSessionDelegate>)delegate {
            [_permissions release];
            _permissions = [permissions retain];
            _sessionDelegate = delegate;

            //[self authorizeWithFBAppAuth:YES safariAuth:YES];
            //You can get auth_token in iOS App!
           [self authorizeWithFBAppAuth:YES safariAuth:NO];      
}

如果您已登录，则可以使用以下方法获取自己的信息。

[facebook requestWithGraphPath:@"me" andDelegate:self];

如果您未登录，则应先通过以下方法登录。

permissions =  [[NSArray arrayWithObjects:
             @"email", @"read_stream", @"user_birthday", 
             @"user_about_me", @"publish_stream", @"offline_access", nil] retain];
if (![facebook isSessionValid]) {
    [facebook authorize:permissions delegate:self];
}

以下帖子救了我。非常感谢！
如何使用 Facebook iOS SDK 检索 Facebook 回复

好运气与快乐编码！
谢谢。

I've had same problem. I checked my privacy settings,permissions,other method etc..., but I couldn't solve it.
Many sites said "check permission for accessing to offline_access/read_stream/publish_stream",I think these are important too,but I couldn't fix it.

Then I found following solution finally, it works fine.

You should change "safariAuth:YES" to "safariAuth:NO" on "Facebook.m" file.

- (void)authorize:(NSArray *)permissions
         delegate:(id<FBSessionDelegate>)delegate {
            [_permissions release];
            _permissions = [permissions retain];
            _sessionDelegate = delegate;

            //[self authorizeWithFBAppAuth:YES safariAuth:YES];
            //You can get auth_token in iOS App!
           [self authorizeWithFBAppAuth:YES safariAuth:NO];      
}

Then you can use following method to get your own info if you are logged in.

[facebook requestWithGraphPath:@"me" andDelegate:self];

if you are not logged in, You should login by following method first.

permissions =  [[NSArray arrayWithObjects:
             @"email", @"read_stream", @"user_birthday", 
             @"user_about_me", @"publish_stream", @"offline_access", nil] retain];
if (![facebook isSessionValid]) {
    [facebook authorize:permissions delegate:self];
}
