1.创建asp.net core webApi项目
默认会引入swagger的Nuget包
<PackageReference Include="Swashbuckle.AspNetCore" Version="6.2.3" />
2.配置基本信息和中文注释（默认是没有中文注释的）
2.1创建一个新的controller
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
namespace webapi.Controllers
{
/// <summary>
/// 学生接口
/// </summary>
[Route("api/[controller]")]
[ApiController]
public class StudentController : ControllerBase
{
/// <summary>
/// 获取学生列表
/// </summary>
/// <returns></returns>
[HttpGet]
public ActionResult GetList()
{
return Ok("学生列表");
}
/// <summary>
///根据Id查询
/// </summary>
/// <param name="Id">学生Id</param>
/// <returns></returns>
[HttpGet("{Id}")]
public ActionResult GetById(int Id)
{
return Ok();
}
/// <summary>
/// 获取token
/// </summary>
/// <param name="token"></param>
/// <returns></returns>
[HttpGet("{id}/{name}")]
public string GetToken([FromHeader] string token)
{
return "123";
}
/// <summary>
/// 添加学生信息
/// </summary>
/// <param name="stu">学生信息</param>
/// <returns></returns>
[HttpPost]
public ActionResult Add([FromBody] StudentInfo stu)
{
return Ok();
}
/// <summary>
/// 修改学生信息
/// </summary>
/// <param name="stu">学生信息</param>
/// <param name="stu"></param>
/// <returns></returns>
[HttpPut]
public ActionResult Update([FromBody] StudentInfo stu)
{
return Ok();
}
/// <summary>
///根据学生学号删除学生
/// </summary>
/// <param name="Id">学号</param>
/// <returns></returns>
[HttpDelete("{Id}")]
public ActionResult DeletById(int Id)
{
return Ok();
}
}
}
2.2创建学生类
namespace webapi
{
/// <summary>
///学生表
/// </summary>
public class StudentInfo
{
/// <summary>
///学号
/// </summary>
public int Sno {
get; set; }
/// <summary>
/// 姓名
/// </summary>
public string Name {
get; set; }
/// <summary>
/// 年龄
/// </summary>
public int Age {
get; set; }
}
}
2.3 生成api中文注释xml(会把控制器上的方法和参数的中文注释生成xml文档)
选择项目-属性-生成-输出-勾选文档文件，xml文档文件路径可以默认
也可以直接双击项目，进入项目配置页面输入
<GenerateDocumentationFile>True</GenerateDocumentationFile>
builder.Services.AddSwaggerGen(p =>
{
p.SwaggerDoc("v1", new Microsoft.OpenApi.Models.OpenApiInfo()
{
Contact = new Microsoft.OpenApi.Models.OpenApiContact()
{
Email = "peng@g.com",
Name = "pzx",
Url = new Uri("http://www.baidu.com")
},
Description = "swagger设置基本信息",
Title = "webapi练习"
});
//加载api中文注释，true是加载控制器上的注释
p.IncludeXmlComments(AppContext.BaseDirectory + Assembly.GetExecutingAssembly().GetName().Name + ".xml", true);
});
运行项目-中文注释就出来了
3.默认的swaggerUI不是太好看我们可以使用自定义的UI
Nuget下载：IGeekFan.AspNetCore.Knife4jUI
<ItemGroup>
<PackageReference Include="IGeekFan.AspNetCore.Knife4jUI" Version="0.0.13" />
<PackageReference Include="Swashbuckle.AspNetCore" Version="6.2.3" />
</ItemGroup>
3.1配置使用Knife4jUI
// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
app.UseSwagger();
app.UseSwaggerUI(p =>
{
p.SwaggerEndpoint("/swagger/v1/swagger.json", "wepai");
p.RoutePrefix = "swagger";//设置前缀，默认swagger
});
//使用自定义UI
app.UseKnife4UI(p =>
{
p.SwaggerEndpoint("/swagger/v1/swagger.json", "wepai");
p.RoutePrefix = "";//设置前缀，默认swagger
});
}
swagger默认使用的swaggerUI,运行路径是
http://localhost:5160/swagger/index.html
要使用Knife4jUI可以把默认的swaggerUI的配置注释掉，把自己路由前缀设置为swagger
如果两个ui都想保留，就把前缀设置未不同，我这swaggerUI的前缀是swagger,Knife4jUI的前缀是空字符串
项目运行选择UI可以在launchSettings.json文件配置 lauchUrl和自己设置的RoutePrefix 值保持一直就可以了。
运行看效果，比默认的ui看起来更加的整洁
4.swaggerUI 配置 Bearer认证
builder.Services.AddSwaggerGen(p =>
{
p.SwaggerDoc("v1", new Microsoft.OpenApi.Models.OpenApiInfo()
{
Contact = new Microsoft.OpenApi.Models.OpenApiContact()
{
Email = "peng@g.com",
Name = "pzx",
Url = new Uri("http://www.baidu.com")
},
Description = "swagger设置基本信息",
Title = "webapi练习"
});
//Bearer 的scheme定义
var securityScheme = new OpenApiSecurityScheme()
{
Description = "JWT Authorization 头使用Bearer 体系方案. 例: \"Authorization: Bearer 你的token\"",
Name = "Authorization",
//参数添加在头部
In = ParameterLocation.Header,
//使用Authorize头部
Type = SecuritySchemeType.Http,
//内容为以 bearer开头
Scheme = JwtBearerDefaults.AuthenticationScheme,//加了这个就不需要 输入Bearer 空格了,只要输入token就可以了
BearerFormat = "JWT"
};
//把所有方法配置为增加bearer头部信息
var securityRequirement = new OpenApiSecurityRequirement
{
{
new OpenApiSecurityScheme
{
Reference = new OpenApiReference
{
Type = ReferenceType.SecurityScheme,
Id = "JWT认证"
}
},
new string[] {
}
}
};
//注册到swagger中
p.AddSecurityDefinition("JWT认证", securityScheme);
p.AddSecurityRequirement(securityRequirement);
//加载api中文注释
p.IncludeXmlComments(AppContext.BaseDirectory + Assembly.GetExecutingAssembly().GetName().Name + ".xml", true);
});
效果如下
Knife4jUI加请求头就比较方便（直接添加就行了，不需要配置）
配置和生成jwt可以看我下面的文章
