一直觉得很好的一个组件,网上介绍少得可怜,没办法,只有自己爬官网了,又是对照git又是看doc文档,总算是玩明白了,现在完全抛弃那个谁谁谁了。因人喜好各取所长吧
先来官方参考地址:
这是scalar的.net 集成文档地址
https://guides.scalar.com/scalar/scalar-api-references/integrations/net-aspnet-core/integration
github地址
https://github.com/scalar/scalar
先放个图,诱惑一下,集成了很多主题,还可以自定主题(留给前端去玩吧)

一、简单使用
1.建立一个API项目,(最小,mvc都可)
2.引用包
dotnet add package Scalar.AspNetCore (当前版本2.9.0)
dotnet add package Microsoft.AspNetCore.OpenApi(当前版本10.0)
3.添加引用
using Scalar.AspNetCore;
4.添加配置,在Program.cs中添加下面配置
builder.Services.AddOpenApi();
if (app.Environment.IsDevelopment())
{
app.MapOpenApi();
app.MapScalarApiReference();
}
现在运行一下,看看,localhost:xxxx/scalar
是不是看到列出漂亮的界面了?
二、基本配置
1.自定义路由
不想使用/salar,可以换成自己的地址
app.MapScalarApiReference("/api-docs");
app.MapScalarApiReference("/docs");
2.多文当或版本控制
// Chain multiple documents
app.MapScalarApiReference(options =>
{
options.AddDocument("v1", "Production API", "api/v1/openapi.json")
.AddDocument("v2-beta", "Beta API", "api/v2-beta/openapi.json", isDefault: true)
.AddDocument("internal", "Internal API", "internal/openapi.json");
});
isDefault: true是默认打开的页面
3.自定义文档的默认调试语言
app.MapScalarApiReference(options =>
{
options.WithDefaultHttpClient(ScalarTarget.CSharp, ScalarClient.HttpClient);
});

它对应右边窗口的语言,基本上都支持,java,php,rust,py,swift
三、高级配置
之前的老版本使用的硬编码option加配置,2.9.0以后,在界面右上角菜单栏上出现了一个编辑配置功能

根据自己的喜好,调试编辑完配置文件后,可以复制到文件中单独保存,真是太贴心了
{
"title": "Aquxa API Documentation",
"slug": "aquxa-api-documentation",
"hideClientButton": true,
"servers": [
{
"url": "http://localhost:5215",
"description": "Development server"
}
],
"showSidebar": true,
"showToolbar": "localhost",//这里特别说明一下,编辑完后,不想出现这个菜单栏,就在这里可以关闭showToolbar: "never"
"operationTitleSource": "summary",
"theme": "solarized",//主题可以自己选,喜欢哪个选哪个
"_integration": "dotnet",
"persistAuth": false,
"telemetry": true,
"layout": "modern",
"isEditable": false,
"isLoading": false,
"hideModels": true,
"documentDownloadType": "both",
"hideTestRequestButton": false,
"hideSearch": false,
"showOperationId": false,
"hideDarkModeToggle": false,
"favicon": "favicon.svg",
"withDefaultFonts": true,
"defaultOpenAllTags": false,
"expandAllModelSections": true,
"expandAllResponses": true,
"orderSchemaPropertiesBy": "alpha",
"orderRequiredPropertiesFirst": true,
"url": "http://localhost:5215/openapi/v1.json"
}
PS:这里特别说明一下,编辑完后,不想出现这个菜单栏,就在这里可以关闭showToolbar: "never"
得到这个文件,保存到wwwroot/js/scalar-config.js,注意,一定要保存到能访问的静态目录里,并在program.cs添加静态目录的配置
app.UseStaticFiles(). //这个要放在scalar配置的前面,不然访问不到
添加配置文件加载
.WithJavaScriptConfiguration("/js/scalar-config.js")

这里费了好大的劲,查官方,看代码,因为官方文档还是老文档,只是简单的概括了一下。最后整出来了
四、文档的编辑
使用最重要的还是API文档编辑,其实它完全用的标准的OpenApi,只要参考这个表就可以完全配置了

[ApiController]
[Route("api/[controller]")]
[ApiExplorerSettings(GroupName = "v1")]
[Tags("Admin")] // 为整个控制器添加标签
public class AdminController : ControllerBase
{
[HttpPost("reload-cache")]
public IActionResult ReloadCache()
{
// 模拟重新加载缓存的操作
return Ok("Cache reloaded successfully");
}
[HttpGet("stats")]
public IActionResult GetStats()
{
return Ok(new { Users = 100, Requests = 1000 });
}
}
下面说一下常用的特性
1.API分组
[ApiExplorerSettings]
这个比较熟悉,它可以分组,分版本,当你分好版本后[ApiExplorerSettings(GroupName = "v1")]/[ApiExplorerSettings(GroupName = "v2")],会在scalar中左上角可以选择,当然,你也可以把它做为组来用

如果有不想显示的API也可以用[ApiExplorerSettings(IgnoreApi = true)]来排除显示
[HttpGet("/private")]
[ApiExplorerSettings(IgnoreApi = true)]
public IActionResult PrivateEndpoint() {
return Ok("This is a private endpoint");
}
2.API分类
[Tags]
分类的API,会归档在一起,方便查询,这样看起来没有那么乱了
[Tags(["Admin", "OtherAPI"])]
[HttpGet("attributes")]
public IResult Attributes()
{
return Results.Ok("Hello world!");
}

3.描述
[EndpointSummary("OtherApi")]
[EndpointDescription("这是一个公开接口,无需认证")]
[HttpGet("attributes")]
public IResult Attributes()
{
return Results.Ok("Hello world!");
}

五、认证授权
这里就使用自己的授权就可以,这里就偷懒找AI完成了。参考部分都有备注
using Scalar.AspNetCore;
using Microsoft.AspNetCore.Authentication;
using Microsoft.Extensions.Options;
using System.Security.Claims;
using System.Text.Encodings.Web;
using Microsoft.AspNetCore.Mvc;
using MyWebApi; // 添加对WeatherForecast的引用
var builder = WebApplication.CreateBuilder(args);
// Add services to the container.
// Learn more about configuring OpenAPI at https://aka.ms/aspnet/openapi
builder.Services.AddOpenApi("v1");
builder.Services.AddOpenApi("v2");
// 添加控制器服务
builder.Services.AddControllers();
// 添加身份验证服务
builder.Services.AddAuthentication("BasicAuthentication")
.AddScheme<AuthenticationSchemeOptions, BasicAuthenticationHandler>("BasicAuthentication", null);
// 添加授权服务
builder.Services.AddAuthorization(options =>
{
options.AddPolicy("ScalarAccess", policy => policy.RequireAuthenticatedUser());
});
// 配置服务器URL,避免端口冲突
builder.WebHost.UseUrls("http://localhost:5215");
var app = builder.Build();
// Configure static file middleware to serve the JavaScript config file
app.UseStaticFiles();
// 添加身份验证和授权中间件
app.UseAuthentication();
app.UseAuthorization();
// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
app.MapOpenApi();
// Add Scalar for API management with JavaScript configuration and authorization
app.MapScalarApiReference("/scalar", options =>
{
options.WithTitle("MyWebApi")
.WithJavaScriptConfiguration("/js/scalar-config.js")
.AddDocument("v1", "Aquxa API Documentation",isDefault: true)
.AddDocument("v2", "Beta API");
})
.RequireAuthorization("ScalarAccess"); // 应用授权策略
}
// 添加控制器路由
app.MapControllers();
app.Run();
// Basic Authentication Handler
public class BasicAuthenticationHandler : AuthenticationHandler<AuthenticationSchemeOptions>
{
public BasicAuthenticationHandler(
IOptionsMonitor<AuthenticationSchemeOptions> options,
ILoggerFactory logger,
UrlEncoder encoder)
: base(options, logger, encoder)
{
}
protected override async Task<AuthenticateResult> HandleAuthenticateAsync()
{
// 检查是否有Authorization头
if (!Request.Headers.ContainsKey("Authorization"))
return AuthenticateResult.NoResult();
try
{
// 解析Basic认证头
var authHeader = Request.Headers["Authorization"].ToString();
if (!authHeader.StartsWith("Basic "))
return AuthenticateResult.NoResult();
var encodedCredentials = authHeader.Substring("Basic ".Length).Trim();
var decodedCredentials = System.Text.Encoding.UTF8.GetString(Convert.FromBase64String(encodedCredentials));
var credentials = decodedCredentials.Split(':', 2);
var username = credentials[0];
var password = credentials[1];
// 验证用户名和密码(这里使用硬编码,实际应用中应从配置或数据库获取)
if (username == "admin" && password == "password123")
{
var claims = new[] { new Claim(ClaimTypes.Name, username) };
var identity = new ClaimsIdentity(claims, Scheme.Name);
var principal = new ClaimsPrincipal(identity);
var ticket = new AuthenticationTicket(principal, Scheme.Name);
return AuthenticateResult.Success(ticket);
}
return AuthenticateResult.Fail("Invalid username or password");
}
catch
{
return AuthenticateResult.Fail("Invalid Authorization Header");
}
}
protected override async Task HandleChallengeAsync(AuthenticationProperties properties)
{
// 发送WWW-Authenticate头以触发浏览器的认证对话框
Response.Headers["WWW-Authenticate"] = "Basic realm=\"Scalar API Documentation\"";
await base.HandleChallengeAsync(properties);
}
}
