WebAPI添加Swagger步骤

1安装NuGet 程序包：Swashbuckle.AspNetCore

2添加swagger中间件：

　　1）ConfigureServices中：

services.AddControllers();

services.AddSwaggerGen(c =>
{
c.SwaggerDoc("v1", new OpenApiInfo
{
Version = "v1",
Title = "ToDo API",
Description = "A simple example ASP.NET Core Web API",
TermsOfService = new Uri("https://www.cnblogs.com/fengdongd/"),
Contact = new OpenApiContact
{
Name = "Shayne Boyer",
Email = string.Empty,
Url = new Uri("https://www.cnblogs.com/fengdongd/"),
},
License = new OpenApiLicense
{
Name = "Use under LICX",
Url = new Uri("https://www.cnblogs.com/fengdongd/"),
}
});
var xmlFile = $"{Assembly.GetExecutingAssembly().GetName().Name}.xml";
var xmlPath = Path.Combine(AppContext.BaseDirectory, xmlFile);
c.IncludeXmlComments(xmlPath);
});

2）Configure中：

app.UseSwagger();
app.UseSwaggerUI(c =>
{
c.SwaggerEndpoint("/swagger/v1/swagger.json", "My API V1");
});

3修改launchsettings.json

设置默认Url："launchUrl": "swagger"
