解析无效会话令牌（代码：209，版本：1.7.1） [英] Parse invalid session token (Code: 209, Version: 1.7.1)

问题描述

我刚刚更新了我的Parse和Facebook SDK（分别为1.7.1和4.0） - 两者都是绝对痛苦的工作，我可能会添加！

然而我现在得到209错误，当我尝试用Facebook登录这里是我的代码的例子

   - （void）loginWithFacebook :( HMSuccessBlock）完成{
 NSArray * permissionsArray = @ [@user_about_me，@user_location，@user_friends，@user_relationships]; 
 
 //使用Facebook登录PFUser 
 
 [PFFacebookUtils logInInBackgroundWithReadPermissions：permissionsArray block：^（PFUser * user，NSError * error）{
 if（！user）{ 
 NSLog（@呃哦，用户取消了Facebook登录。）; 
 UIAlertView * alert = [[UIAlertView alloc] initWithTitle：@登录错误
消息：error.localizedDescription 
委托：nil 
 cancelButtonTitle：nil 
 otherButtonTitles： @Dismiss，nil]; 
 [alert show]; 
完成（NO，错误）; 
 
} else if（user.isNew）{
 NSLog（@用户注册并通过Facebook登录！）; 
 if（completion）{
 completion（YES，nil）; 
} 
} else {
 NSLog（@用户通过Facebook登录！）; 
完成（YES，nil）; 
} 
}]; 
  

}

错误]：无效的会话令牌（代码：209，版本：1.7.1）

我的初步想法是，这个问题与我的应用程序代理中的代码有关 - 在旧版本的facebooksdk我将应用以下代码

   - （BOOL）应用程序：（UIApplication *）应用程序openURL： （NSURL *）url sourceApplication：（NSString *）sourceApplication注释：（id）注释{
 return [FBAppCall handleOpenURL：url 
 sourceApplication：sourceApplication 
 withSession：[PFFacebookUtils session]]; 
  

}

找到任何东西在更新版本中复制，因此我的代码是

   - （BOOL）应用程序：（UIApplication *）应用程序openURL （NSURL *）url sourceApplication：（NSString *）sourceApplication注释：（id）注释{
 return [[FBSDKApplicationDelegate sharedInstance]应用程序：应用程序
 openURL：url 
 sourceApplication：sourceApplication 
注释：注释]; 
  

}

任何帮助都会很大赞赏

解决方案

发布的一些答案是临时修复 - 但是如果用户注销并尝试登录，则可能会再次出现问题再次回来 - 我认为这是由于我允许匿名用户 - 唯一的方法我可以清除它是在登录之前调用[pfuser注销]

I have just update both my Parse and Facebook SDK's (1.7.1 and 4.0 respectively) - both were an absolute pain to get working I might add!

However I now getting 209 errors when I try to log in with facebook here's an example of my code

- (void)loginWithFacebook:(HMSuccessBlock)completion{
NSArray *permissionsArray = @[@"user_about_me",@"user_location",@"user_friends",@"user_relationships"];

// Login PFUser using Facebook

[PFFacebookUtils logInInBackgroundWithReadPermissions:permissionsArray block:^(PFUser *user, NSError *error) {
    if (!user) {
        NSLog(@"Uh oh. The user cancelled the Facebook login.");
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Log In Error"
                                                        message:error.localizedDescription
                                                       delegate:nil
                                              cancelButtonTitle:nil
                                              otherButtonTitles:@"Dismiss", nil];
        [alert show];
        completion(NO, error);

    } else if (user.isNew) {
        NSLog(@"User signed up and logged in through Facebook!");
        if (completion) {
            completion(YES, nil);
        }
    } else {
        NSLog(@"User logged in through Facebook!");
           completion(YES, nil);
    }
}];

}

Which yeilds the following [Error]: invalid session token (Code: 209, Version: 1.7.1)

My initial thinking is that the issue is something to do with my code in the app delegate - on older versions of the facebooksdk I would apply the following code

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
return [FBAppCall handleOpenURL:url
              sourceApplication:sourceApplication
                    withSession:[PFFacebookUtils session]];

}

However I cant seem to find anything to replicate this in the updated version, hence my code being

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
return [[FBSDKApplicationDelegate sharedInstance] application:application
                                                      openURL:url
                                            sourceApplication:sourceApplication
                                                   annotation:annotation];

}

Any help would be greatly appreciated

解决方案

Some of the answers posted were temporary fixes - however the problem could reoccur later if a user logged out and tried to log back in again - I think this was due to me allowing anonymous users also - the only way I could clear it is to call [pfuser logout] prior to log in
