Task 6: Create Seed Data

Task Description

Files:

Create: src/Fengling.AuthService/Data/SeedData.cs
Modify: src/Fengling.AuthService/Program.cs

Implementation Steps

Step 1: Create seed data class

Create: src/Fengling.AuthService/Data/SeedData.cs

using Fengling.AuthService.Models;
using Microsoft.AspNetCore.Identity;
using Microsoft.EntityFrameworkCore;

namespace Fengling.AuthService.Data;

public static class SeedData
{
    public static async Task Initialize(IServiceProvider serviceProvider)
    {
        using var scope = serviceProvider.CreateScope();
        var context = scope.ServiceProvider.GetRequiredService<ApplicationDbContext>();
        var userManager = scope.ServiceProvider.GetRequiredService<UserManager<ApplicationUser>>();
        var roleManager = scope.ServiceProvider.GetRequiredService<RoleManager<ApplicationRole>>();

        context.Database.EnsureCreated();

        var adminRole = await roleManager.FindByNameAsync("Admin");
        if (adminRole == null)
        {
            adminRole = new ApplicationRole
            {
                Name = "Admin",
                Description = "System administrator",
                CreatedTime = DateTime.UtcNow
            };
            await roleManager.CreateAsync(adminRole);
        }

        var adminUser = await userManager.FindByNameAsync("admin");
        if (adminUser == null)
        {
            adminUser = new ApplicationUser
            {
                UserName = "admin",
                Email = "admin@fengling.local",
                RealName = "系统管理员",
                Phone = "13800138000",
                TenantId = 1,
                EmailConfirmed = true,
                IsDeleted = false,
                CreatedTime = DateTime.UtcNow
            };

            var result = await userManager.CreateAsync(adminUser, "Admin@123");
            if (result.Succeeded)
            {
                await userManager.AddToRoleAsync(adminUser, "Admin");
            }
        }

        var testUser = await userManager.FindByNameAsync("testuser");
        if (testUser == null)
        {
            testUser = new ApplicationUser
            {
                UserName = "testuser",
                Email = "test@fengling.local",
                RealName = "测试用户",
                Phone = "13900139000",
                TenantId = 1,
                EmailConfirmed = true,
                IsDeleted = false,
                CreatedTime = DateTime.UtcNow
            };

            var result = await userManager.CreateAsync(testUser, "Test@123");
            if (result.Succeeded)
            {
                var userRole = new ApplicationRole
                {
                    Name = "User",
                    Description = "普通用户",
                    CreatedTime = DateTime.UtcNow
                };
                await roleManager.CreateAsync(userRole);
                await userManager.AddToRoleAsync(testUser, "User");
            }
        }
    }
}

Step 2: Update Program.cs to call seed data

Edit: src/Fengling.AuthService/Program.cs (add after var app = builder.Build();)

using (var scope = app.Services.CreateScope())
{
    await Data.SeedData.Initialize(scope.ServiceProvider);
}

Step 3: Run to create seed data

Run:

dotnet run

Expected: Logs show admin user created successfully

Run:

curl -X POST http://localhost:5000/api/auth/login \
  -H "Content-Type: application/json" \
  -d '{"userName":"admin","password":"Admin@123","tenantId":1}'

Expected: Returns token (placeholder for now)

Step 5: Commit

git add src/Fengling.AuthService/Data/SeedData.cs src/Fengling.AuthService/Program.cs
git commit -m "feat(auth): add seed data for admin and test users"

Context

This task creates initial seed data including admin and test users with default passwords. This allows immediate testing of the authentication service.

Tech Stack: ASP.NET Core Identity

Verification

SeedData class created
Program.cs calls seed data on startup
Admin user created: admin/Admin@123
Test user created: testuser/Test@123
Both users assigned to tenant 1
Build succeeds
Committed to git

Notes

Passwords should be changed in production
All users assigned to tenant 1 for initial setup
