Question

我最近将我的应用程序从Parse Server迁移到我自己的自定义服务器。我试图找到一种方法来访问会话令牌，而无需在我的项目中导入Parse SDK。我需要会话令牌，所以我不必重新验证我当前登录的用户。

到目前为止，我使用以下方法访问它，这需要导入解析sdk：

        PFUser.current()?.saveInBackground(block: { [weak self] (success, error) in
            if let error = error {
                Log.error?.message(error.localizedDescription)
                return
            }
            guard let sessionToken = PFUser.current()?.sessionToken else {
                Log.error?.message("Did not get session token even after saving user")
                return
            }
        })

我看到的另一个解决方案是parse的私有文档目录，但我只能从那里获得applicationId，installationId和config：

class ParseHelper {    
    var parsePrivateDocumentsDirectory: URL? {
        let filemanager = FileManager.default
        guard let libraryDirectory = filemanager.urls(for: .libraryDirectory, in: .userDomainMask).last else {
            return nil
        }

        guard let parseDirectory = URL(string: "Private%20Documents/Parse/", relativeTo: libraryDirectory) else {
            return nil
        }
        return parseDirectory
    }

    func parseFile(_ filename: String) -> URL? {
        let filemanager = FileManager.default
        guard let parseDirectory = self.parsePrivateDocumentsDirectory else {
            return nil
        }

        guard let installationIdUrl = URL(string: filename, relativeTo: parseDirectory) else {
            return nil
        }

        if filemanager.fileExists(atPath: installationIdUrl.path) {
            return installationIdUrl
        } else {
            return nil
        }
    }

    var installationId: String? {
        guard let fileURL = self.parseFile("installationId"), let data = try? Data(contentsOf: fileURL) else {
            return nil
        }
        let string = String(data: data, encoding: String.Encoding.utf8)
        return string
    }

    var applicationId: String? {
        guard let fileURL = self.parseFile("applicationId"), let data = try? Data(contentsOf: fileURL) else {
            return nil
        }
        let string = String(data: data, encoding: String.Encoding.utf8)
        return string
    }

    var config: String? {
        guard let fileURL = self.parseFile("config"), let data = try? Data(contentsOf: fileURL) else {
            return nil
        }
        let string = String(data: data, encoding: String.Encoding.utf8)
        return string
    }
}

Private Documents/Parse中可用的唯一文件是：

的applicationID
currentInstallation
currentUser
installationId

另一方面，sessionToken存储在钥匙串中密钥应为$APP_BUNDLE_ID.com.parse.sdk（Official info和source code，here's是用于保存数据的函数的来源。）
