解析错误代码 209 和 -34018 [英] Parse error codes 209 and -34018

问题描述

我花了几个小时在 Parse 上学习用户管理，认为考虑到它已经是一个成熟的服务这么久，这会很容易.

I have spent several hours learning user management on Parse, thinking it would be easy considering it's been an established service for so long.

关于自动用户"和会话的文档很差.

There is poor documentation around 'automatic user' and sessions.

我正在尝试构建一个允许用户在决定注册之前匿名存在的应用程序(使用 [PFUser enableAutomaticUser]).

I am trying to build an App that allows the user to exist anonymously (using [PFUser enableAutomaticUser]), before they decide to sign up.

注册步骤:

1. 从用户界面收集用户详细信息
2. 注销当前自动用户并等待成功
3. 成功后使用[PFUser user]创建一个用户对象并赋值
4. 在新用户实例上调用 signUpInBackgroundWithBlock

1. Gather user details from the UI
2. Log out current automatic user and wait for success
3. Upon success create a user object using [PFUser user] and assign values
4. Call signUpInBackgroundWithBlock on the new user instance

在执行上述操作时，我有时会遇到以下错误(是的，只是有时).

I sometimes get the following errors (yes, only sometimes), when doing the above.

[错误]:PFKeychainStore 无法获取键 'currentUser' 的对象，错误:-34018

[Error]: PFKeychainStore failed to get object for key 'currentUser', with error: -34018

[错误]:无效的会话令牌(代码:209，版本:1.7.0)

[Error]: invalid session token (Code: 209, Version: 1.7.0)

我也得到了一个脏数据库，因为我不知道如何删除之前创建的自动用户.我尝试保留旧用户的对象 ID 并使用 deleteEventually 但这不起作用?

I also end up with a dirty database, because I don't know how to delete the automatic user that was previously created. I tried keeping the object id of the old user around and using deleteEventually but that didn't work?

任何关于如何实现这一目标的建议都会很棒.

Any advice on how you would go about achieving this would be great.
