flutter pub add jwt_io基于插件公开信息、社区数据与项目使用情况整理的选型参考。
jwt_io 是一个用于根据 RFC 7519 标准对 JSON Web Tokens (JWT) 进行编码、解码和验证的 Flutter/Dart 包。它通过提供生成签名令牌和验证其完整性的工具，实现各方之间安全地传输声明。该包支持 Android、iOS、Web、macOS、Windows 和 Linux 等多个平台，非常适合需要身份验证或授权的跨平台应用程序。它可通过 pub.dev 与 Flutter 项目无缝集成。

JSON Web Tokens are an open, industry standard RFC 7519 method for representing claims securely between two parties.
JWT_IO allows you to decode, verify and generate JWT.
main () {
String yourToken = "Your JWT";
Map<String, dynamic> decodedToken = JwtToken.payload(yourToken);
/*
If the token has a valid format, you will get a Map<String, dynamic>
Your decoded token can look like:
{
"sub": "1234567890",
"name": "John Doe",
"iat": 1516239022,
}
*/
}
main () {
String yourToken = "Your JWT";
bool hasExpired = JwtToken.isExpired(yourToken);
// You will get a true / false response
// true: if the token is already expired
// false: if the token is not expired
}
main () {
String yourToken = "Your JWT";
DateTime expirationDate = JwtToken.getExpirationDate(token);
// 2025-01-13 13:04:18.000
print(expirationDate);
}
// Token payload must include an 'iat' field
main () {
String yourToken = "Your JWT";
Duration tokenTime = JwtToken.getTokenTime(token);
// 15
print(tokenTime.inDays);
}
