如何使用OAuth在Parse iOS SDK中验证用户？ [英] How to authenticate a user in Parse iOS SDK using OAuth?

问题描述

Parse Server提供OAuth身份验证。如何使用Parse Server的预定义OAuth模块，例如Facebook，注册新用户或登录'_User'类的现有用户？

Parse Server offers OAuth authentication. How can I use the Parse Server's predefined OAuth modules, e.g. Facebook, to sign up a new user or login an existing user of the '_User' class?

解析服务器 docs 提供了有关如何配置OAuth模块的示例。但是如何在iOS项目中使用它来登录或注册用户呢？

The Parse Server docs give examples on how to configure the OAuth modules. But how do I use it in an iOS project to login or signup a user?

推荐答案

1，创建一个从两者扩展的类NSObject和PFUserAuthenticationDelegate。

1, create a class extends from both NSObject and PFUserAuthenticationDelegate.

class AuthDelegate:NSObject, PFUserAuthenticationDelegate {
    func restoreAuthenticationWithAuthData(authData: [String : String]?) -> Bool {
        return true
    }
}

2，注册此身份验证委托

2, register this authentication delegate

// parmeter 'forAuthType' is the name of file defined in 
// https://github.com/parse-community/parse-server/blob/master/src/Adapters/Auth/index.js
// such as: google, github, linkedin ......
PFUser.registerAuthenticationDelegate(AuthDelegate(), forAuthType: "google")

3，使用PFUser.logInWithAuthTypeInBackground方法将用户信息存储到_User

3, using PFUser.logInWithAuthTypeInBackground method to store user info to _User

// for google oauth, authData format will be
// ["id":"PUT_USER_ID_HERE","accesstoken":"PUT_TOKEN_HERE"]
PFUser.logInWithAuthTypeInBackground("google", authData:[.....])

4，你会看到在_User中创建了一条记录，只有objectId和authData

4, you will see a record is created in _User, with only objectId and authData
