不稳定的永久登录 [英] Flutter persistent login

问题描述

我正在尝试使用django后端登录用户.效果很好，我用 shared_preferences 包保存了令牌和电子邮件地址的组合.但是，该程序包建议不要存储敏感信息，而令牌显然是该敏感信息.我要保持登录状态，直到我退出该应用程序.

I am trying to login a user using a django backend. This works fine and I saved a token and email address combination with the shared_preferences package. The package however recommends not to store sensitive information, which the token obviously is. I want to stay logged in until I log out of the app.

我如何做到这一点?

推荐答案

您可以使用软件包 https://pub.dev/packages/flutter_secure_storage
Flutter插件可将数据存储在安全存储中:
钥匙串用于iOS
AES加密用于Android

You can use package https://pub.dev/packages/flutter_secure_storage
A Flutter plugin to store data in secure storage:
Keychain is used for iOS
AES encryption is used for Android

代码段

import 'package:flutter_secure_storage/flutter_secure_storage.dart';

// Create storage
final storage = new FlutterSecureStorage();

// Read value 
String value = await storage.read(key: key);

// Read all values
Map<String, String> allValues = await storage.readAll();

// Delete value 
await storage.delete(key: key);

// Delete all 
await storage.deleteAll();

// Write value 
await storage.write(key: key, value: value);
