Identity Core migration to Java
问题
我有一个使用.NET Core制作的Web API项目，我正在使用IdentityCore来进行用户密码注册和登录。然而，我需要将这个API迁移到Java。我如何在不丢失所有用户数据的情况下进行迁移？是否有办法复制IdentityCore使用的算法？

你使用 .net core Identity 时，你的数据被保存在数据库中：https://learn.microsoft.com/en-us/aspnet/core/security/authentication/customize-identity-model?view=aspnetcore-3.1
因此，如果你已经在你的 API 中正确设置了 IdentityCore 授权，那么在你的配置中应该有一个连接字符串，类似这样：
{
"ConnectionStrings": {
"DefaultConnection": "Server=(localdb)\\MSSQLLocalDB;Database= IdentityDB;Trusted_Connection=True;MultipleActiveResultSets=true"
}
}
你可以按照这个配置，提取表和数据，然后就完成了。

英文:
Your data are saved in a database when you are using .net core Identity: https://learn.microsoft.com/en-us/aspnet/core/security/authentication/customize-identity-model?view=aspnetcore-3.1
So if you have correctly setup the IdentityCore authorization in your api, then there should be a connection string somewhere in your config like this:
{
"ConnectionStrings": {
"DefaultConnection": "Server=(localdb)\\MSSQLLocalDB;Database= IdentityDB;Trusted_Connection=True;MultipleActiveResultSets=true"
}
}
You can follow it, extract the tables and the data and you are set.
