Perfect Local Authentication (PostgreSQL) 简体中文

Perfect Local Authentication (PostgreSQL) Library

This package provides Local Authentication libraries for projects that require locally stored and handled authentication.

Full documentation can be found at http://www.perfect.org/docs/authentication.html

A template application can be found at https://github.com/PerfectlySoft/Perfect-Local-Auth-PostgreSQL-Template, providing a fully functional starting point, as well as demonstrating the usage of the system.

This package builds with Swift Package Manager and is part of the Perfect project. It was written to be stand-alone and so does not require PerfectLib or any other components.

Ensure you have installed and activated the latest Swift 3.x tool chain.

Adding to your project

Add this project as a dependency in your Package.swift file.

.Package(url: "https://github.com/PerfectlySoft/Perfect-LocalAuthentication-PostgreSQL.git", majorVersion: 1)

To then use the LocalAuthentication module in your code:

import LocalAuthentication

Configuration

It is important to configure the following in main.swift to set up database and session configuration:

Import the required modules:

import PerfectSession
import PerfectSessionPostgreSQL
import PerfectCrypto
import LocalAuthentication

Initialize PerfectCrypto:

let _ = PerfectCrypto.isInitialized

Now set some defaults:

// Used in email communications
// The Base link to your system, such as http://www.example.com/
var baseURL = ""

// Configuration of Session
SessionConfig.name = "perfectSession" // <-- change
SessionConfig.idle = 86400
SessionConfig.cookieDomain = "localhost" //<-- change
SessionConfig.IPAddressLock = false
SessionConfig.userAgentLock = false
SessionConfig.CSRF.checkState = true
SessionConfig.CORS.enabled = true
SessionConfig.cookieSameSite = .lax

Detailed Session configuration documentation can be dound at https://www.perfect.org/docs/sessions.html

The database and email configurations should be set as follows (if using JSON file config):

let opts = initializeSchema("./config/ApplicationConfiguration.json") // <-- loads base config like db and email configuration
httpPort = opts["httpPort"] as? Int ?? httpPort
baseURL = opts["baseURL"] as? String ?? baseURL

Otherwise, these will need to be set equivalent to this function https://github.com/PerfectlySoft/Perfect-LocalAuthentication-PostgreSQL/blob/master/Sources/LocalAuthentication/Schema/InitializeSchema.swift.

Set the session driver:

let sessionDriver = SessionPostgresDriver()

Request & Response Filters

The following two session filters need to be added to your server config:

// (where filter is a [[String: Any]] object)
filters.append(["type":"request","priority":"high","name":SessionPostgresFilter.filterAPIRequest])
filters.append(["type":"response","priority":"high","name":SessionPostgresFilter.filterAPIResponse])

For example, see https://github.com/PerfectlySoft/Perfect-Local-Auth-PostgreSQL-Template/blob/master/Sources/PerfectLocalAuthPostgreSQLTemplate/configuration/Filters.swift

Add routes for login, register etc

The following routes can be added as needed or customized to add login, logout, register:

// Login
routes.append(["method":"get", "uri":"/login", "handler":Handlers.login]) // simply a serving of the login GET
routes.append(["method":"post", "uri":"/login", "handler":LocalAuthWebHandlers.login])
routes.append(["method":"get", "uri":"/logout", "handler":LocalAuthWebHandlers.logout])

// Register
routes.append(["method":"get", "uri":"/register", "handler":LocalAuthWebHandlers.register])
routes.append(["method":"post", "uri":"/register", "handler":LocalAuthWebHandlers.registerPost])
routes.append(["method":"get", "uri":"/verifyAccount/{passvalidation}", "handler":LocalAuthWebHandlers.registerVerify])
routes.append(["method":"post", "uri":"/registrationCompletion", "handler":LocalAuthWebHandlers.registerCompletion])

// JSON
routes.append(["method":"get", "uri":"/api/v1/session", "handler":LocalAuthJSONHandlers.session])
routes.append(["method":"get", "uri":"/api/v1/logout", "handler":LocalAuthJSONHandlers.logout])
routes.append(["method":"post", "uri":"/api/v1/register", "handler":LocalAuthJSONHandlers.register])
routes.append(["method":"login", "uri":"/api/v1/login", "handler":LocalAuthJSONHandlers.login])

An example can be found at https://github.com/PerfectlySoft/Perfect-Local-Auth-PostgreSQL-Template/blob/master/Sources/PerfectLocalAuthPostgreSQLTemplate/configuration/Routes.swift

Testing for authentication:

The user id can be accessed as follows:

request.session?.userid ?? ""

If a user id (i.e. logged in state) is required to access a page, code such as this could be used to detect and redirect:

let contextAuthenticated = !(request.session?.userid ?? "").isEmpty
if !contextAuthenticated { response.redirect(path: "/login") }
