写在前面

Swagger 是一个规范和完整的框架，用于生成、描述、调用和可视化 RESTful 风格的 Web 服务。 本文记录如何配置基于Swagger 的 ASP.NET Core 应用程序的 OpenAPI 规范。

需要从NuGet 安装 Swashbuckle.AspNetCore 包

代码实现

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddControllers();
 
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen(c =>
{
    c.SwaggerDoc("v1", new()
    {
        Title = builder.Environment.ApplicationName,
        Version = "v1"
    });
});


var app = builder.Build();
 
if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI(c => c.SwaggerEndpoint("/swagger/v1/swagger.json",
                                $"{builder.Environment.ApplicationName} v1"));
}

app.UseHttpsRedirection();

app.UseAuthorization();

app.MapControllers();

app.MapGet("/swag", () => "Hello Swagger!");
app.MapGet("/skipme", () => "Skipping Swagger.")
                    .ExcludeFromDescription();

app.Run();
