英文:
Command 'update-database' is not working in .NET 6 Entity Framework for API
问题
命令 update-database 在 .NET 6 实体框架中的 API 中不起作用。控制台窗口显示错误消息：
> 未初始化 ConnectionString 属性
在我运行命令 update-database 后。命令 add-migration 正常工作。
appsettings.json 文件：
{
"Logging": {
"LogLevel": {
"Default": "Information",
"Microsoft.AspNetCore": "Warning"
}
},
"AllowedHosts": "*",
"ConnectionStrings": {
"DefaultConnection": "Server=(localdb)\\mssqllocaldb; Database=MovieContext; Trusted_Connection=True; MultipleActiveResultSets=true"
}
}
Program.cs 文件：
using AspNetCoreWebApi6.Models;
using Microsoft.EntityFrameworkCore;
var builder = WebApplication.CreateBuilder(args);
// 将服务添加到容器中。
builder.Services.AddDbContext<MovieContext>(options =>
options.UseSqlServer(builder.Configuration.GetConnectionString("MovieContext")));
builder.Services.AddControllers();
// 了解有关配置 Swagger/OpenAPI 的更多信息，请访问 https://aka.ms/aspnetcore/swashbuckle
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();
var app = builder.Build();
// 配置 HTTP 请求管道。
if (app.Environment.IsDevelopment())
{
app.UseSwagger();
app.UseSwaggerUI();
}
app.UseHttpsRedirection();
app.UseAuthorization();
app.MapControllers();
app.Run();

你正试图获取名为 "MovieContext" 的连接字符串，而不是 "DefaultConnection"。

You are trying to get a connection string named "MovieContext" instead of "DefaultConnection"
