我成功地使用 mongolab 将 parse 迁移到 parse-server。现在一切都按预期工作,除了当我使用 MongoLab 使用 PFUser 登录时,我的 PFRelation 对象始终为空。

在我的 AppDelegate 中,当我运行此代码(官方 Parse)时:

[Parse setApplicationId:@"xxxxxx"
              clientKey:@"xxxxxx"];
[PFUser enableRevocableSessionInBackground];

HomeView.m:

self.currentUser = [PFUser currentUser];
self.friendsRelation = [[PFUser currentUser] objectForKey:@"friends"];
NSLog(@"%@", self.currentUser);
NSLog(@"%@", self.friendsRelation);

登录后,我的 HomeView 记录以下内容:

2016-02-28 23:25:38.756 ChillN[4131:57119] <PFUser: 0x7fe0b3e4fc10, objectId: MZdPHaqByR, localId: (null)> {
    friends = "<PFRelation: 0x7fe0b3e4f900, 0x7fe0b3e4fc10.friends -> _User>";
    phone = "06 19 05 39 30";
    surname = a;
    username = a;
}
2016-02-28 23:25:38.756 ChillN[4131:57119] <PFRelation: 0x7fe0b3e4f900, 0x7fe0b3e4fc10.friends -> _User>

所以一切正常。

现在使用 mongolab 数据库:

应用委托:

[Parse initializeWithConfiguration:[ParseClientConfiguration configurationWithBlock:^(id<ParseMutableClientConfiguration> configuration) {
    configuration.applicationId = @"xxxxxxx";
    configuration.clientKey = @"xxxxxxx";
    configuration.server = @"http://xxxxxxx.herokuapp.com/parse/";
}]];

登录后,我的 HomeView 会记录以下内容:

2016-02-28 23:29:21.785 ChillN[4281:59046] <PFUser: 0x7fa43c09ed20, objectId: MZdPHaqByR, localId: (null)> {
    phone = "06 19 05 39 27";
    surname = a;
    username = a;
}
2016-02-28 23:29:21.786 ChillN[4281:59046] (null)

对于日志记录,我只是使用:

[PFUser logInWithUsernameInBackground:user
                                 password:password block:^(PFUser *user, NSError *error) {}];

这是我的数据库:解析: 解析数据库

Heroku(蒙古实验室): MongoLab 数据库

这是来自 MongoLab 的用户记录:

{
    "_id": "MZdPHaqByR",
    "_perishable_token": "SHuhtWl0EoxxmNLOkspmp1vBF",
    "username": "a",
    "phone": "06 19 05 39 27",
    "surname": "a",
    "_session_token": "zO2drjzrO0To1q0JiohaL8f4v",
    "_hashed_password": "$2a$10$a7j5yB7uFDtv.YnHESVJgO9Io.nci8hbx7vngOo.FyzA3qBLxw38G",
    "_created_at": {
        "$date": "2016-02-28T21:55:48.548Z"
    },
    "_updated_at": {
        "$date": "2016-02-28T22:03:45.704Z"
    }
}

这只是我的代码中的一个错误,我不得不替换:

self.friendsRelation = [[PFUser currentUser] objectForKey:@"friends"];

self.friendsRelation = [[PFUser currentUser] relationForKey:@"friends"];

希望这会帮助另一个人。干杯!
