# SimApi for .NET
|
||
|
||
> NuGet: `Simcu.SimApi` | 目标框架: `net8.0` / `net9.0` / `net10.0`
|
||
> 作者: xRain@SimcuTeam
|
||
|
||
ASP.NET Core API 基础框架库，提供统一异常拦截、响应封装、Token 认证、Swagger 文档、S3 存储、MQTT 通信、Hangfire 任务调度、Auth Center 网关鉴权与 IAM 权限管理。
|
||
|
||
---
|
||
|
||
## 快速开始
|
||
|
||
```csharp
|
||
var builder = WebApplication.CreateBuilder(args);
|
||
builder.Services.AddSimApi(options =>
|
||
{
|
||
options.RedisConfiguration = "localhost:6379";
|
||
options.EnableSimApiAuth = true;
|
||
options.EnableSimApiDoc = true;
|
||
|
||
options.ConfigureSimApiDoc(doc =>
|
||
{
|
||
doc.DocumentTitle = "我的API";
|
||
doc.ApiGroups = [new("api", "公共接口"), new("admin", "管理接口")];
|
||
});
|
||
});
|
||
|
||
var app = builder.Build();
|
||
app.UseSimApi();
|
||
app.Run();
|
||
```
|
||
|
||
---
|
||
|
||
## 核心概念
|
||
|
||
### 统一响应格式
|
||
|
||
所有接口输出 JSON，HTTP 状态码始终 `200`，错误信息在 `code` 字段：
|
||
|
||
| code | 含义 |
|
||
| ---- | ---------- |
|
||
| 200 | 成功 |
|
||
| 204 | 无数据 |
|
||
| 400 | 参数错误 |
|
||
| 401 | 需要登录 |
|
||
| 403 | 无权访问 |
|
||
| 404 | 资源不存在 |
|
||
| 500 | 服务器错误 |
|
||
|
||
### 异常处理流程
|
||
|
||
```
|
||
请求 → SimApiExceptionMiddleware(全异常捕获→HTTP 200+JSON)
|
||
→ SimApiAuthMiddleware(Token→LoginInfo)
|
||
→ [SimApiSign] Filter(签名)
|
||
→ [SimApiAuth] Filter(登录检查)
|
||
→ OnActionExecuting(模型验证→code 400)
|
||
→ Action
|
||
→ SimApiResponseFilter(封装响应)
|
||
```
|

|
||
|
||

|
||
|
||
## 1. 错误处理 — SimApiError
|
||
|
||
独立静态类 `SimApi.Helpers.SimApiError`。所有错误最终 → `throw new SimApiException(code, message)` → 中间件捕获。
|
||
|
||
**使用**: 文件顶部加 `using static SimApi.Helpers.SimApiError;`
|
||
|
||
### 完整方法签名
|
||
|
||
```csharp
|
||
// 直接抛错
|
||
void Error(int code = 500, string message = "");
|
||
|
||
// condition 为 true 时抛错 (code 默认 400)
|
||
void ErrorWhen([DoesNotReturnIf(true)] bool condition, int code = 400, string message = "");
|
||
|
||
// 同上（别名）
|
||
void ErrorWhenTrue([DoesNotReturnIf(true)] bool condition, int code = 400, string message = "");
|
||
|
||
// condition 为 false 时抛错
|
||
void ErrorWhenFalse([DoesNotReturnIf(false)] bool condition, int code = 400, string message = "");
|
||
|
||
// obj 为 null 时抛错 (code 默认 404)
|
||
void ErrorWhenNull([NotNull] object? condition, int code = 404, string message = "");
|
||
```
|
||
|
||
### 示例
|
||
|
||
```csharp
|
||
using static SimApi.Helpers.SimApiError;
|
||
|
||
var user = db.Users.Find(id);
|
||
ErrorWhenNull(user, 404, "用户不存在");
|
||
ErrorWhen(amount <= 0, 400, "金额无效");
|
||
ErrorWhenFalse(hasPermission, 403, "无权操作");
|
||
Error(500, "服务器内部错误");
|
||
```
|
||
|
||
---
|
||
|
||
## 2. 控制器 — SimApiBaseController
|
||
|
||
```csharp
|
||
public class SimApiBaseController : Controller
|
||
{
|
||
// 当前登录信息（需 EnableSimApiAuth）
|
||
protected SimApiLoginItem LoginInfo => (SimApiLoginItem)HttpContext.Items["LoginInfo"]!;
|
||
protected string LoginToken => (string)HttpContext.Items["LoginToken"]!;
|
||
|
||
// OnActionExecuting 自动验证 ModelState → 无效时抛 code 400
|
||
}
|
||
```
|
||
|
||
**内建**: `[Consumes("application/json")]` + `[Produces("application/json")]`
|
||
|
||
### 自动路由
|
||
|
||
| 路由 | 方法 | 条件 | 说明 |
|
||
| ----------------------- | -------- | -------------------------------------------- | ------------------------ |
|
||
| `/versions` | GET/POST | `VersionRoute != null`(默认) | 返回 SimApi/App 版本 |
|
||
| `/user/info` | POST | `EnableSimApiAuth` + `UserInfoRoute != null` | 需登录，返回 LoginInfo |
|
||
| `/auth/logout` | POST | `EnableSimApiAuth` + `LogoutRoute != null` | 退出登录（可自定义路由） |
|
||
| `/swagger` | GET | `EnableSimApiDoc` | Swagger UI |
|
||
| `/jobs` | GET | `EnableJob` + `DashboardUrl != null` | Hangfire 控制台 |
|
||
| `/exception/{code:int}` | GET | 始终 | 错误反馈页面 |
|
||
|
||
### 返回值规范
|
||
|
||
| 场景 | 返回类型 |
|
||
| ---------- | ------------------------- |
|
||
| 写操作 | `void` |
|
||
| 单条查询 | 直接 Entity |
|
||
| 列表查询 | `Entity[]` |
|
||
| 分页 | `PageResponse<Entity[]>` |
|
||
| 自定义状态 | `SimApiBaseResponse` |
|
||
| 跳封装 | 方法加 `[OriginResponse]` |
|
||
|
||

|
||
|
||
## 3. 认证系统 — SimApiAuth
|
||
|
||
```csharp
|
||
string Login(SimApiLoginItem loginItem, TimeSpan? expireTime = null, string? token = null); // 默认7天
|
||
string Update(SimApiLoginItem loginItem, string token);
|
||
SimApiLoginItem? GetLogin(string token);
|
||
SimApiLoginItem[] GetAllLogins(string userId);
|
||
void Logout(string token);
|
||
void LogoutAll(string userId);
|
||
```
|
||
|
||
```csharp
|
||
// LoginItem 结构
|
||
public class SimApiLoginItem {
|
||
required string Id;
|
||
string[] Type = ["user"];
|
||
Dictionary<string, string> Meta = [];
|
||
Dictionary<string, object?> Extra = [];
|
||
}
|
||
```
|
||
|
||
**Token 传参**: Header `Token: <value>`
|
||
|
||
### 认证后处理 Hook — ISimApiAuthChecker
|
||
|
||
```csharp
|
||
public interface ISimApiAuthChecker {
|
||
void Run(SimApiLoginItem loginItem, string token);
|
||
}
|
||
// 实现后自动注册为 Scoped，每次认证后调用
|
||
```
|
||
|
||
---
|
||
|
||
## 4. AuthSDK — Auth Center 网关 & IAM
|
||
|
||
启用: `EnableSimApiAuthGate = true`
|
||
|
||
### 4.1 配置
|
||
|
||
```csharp
|
||
options.EnableSimApiAuthGate = true;
|
||
options.ConfigureSimApiAuthCenter(gate =>
|
||
{
|
||
gate.Server = "https://auth.coce.cc";
|
||
gate.AppId = "your-app-id";
|
||
gate.AppKey = "your-app-key";
|
||
gate.UseMiddleware = true; // 内部应用启用，解析 X-SimApi-Gate-Auth Header
|
||
gate.UseIam = true; // 启用 IAM
|
||
});
|
||
```
|
||
|
||
### 4.2 SimApiAuthClient
|
||
|
||
继承 `SimApiHttpClient`，自动配置 Server/AppId/AppKey，对 Auth Center 发起签名请求。
|
||
|
||
### 4.3 SimApiAuthCenter — Auth Center API
|
||
|
||
```csharp
|
||
// === 签名验证 ===
|
||
void VerifySign(string appId, string timestamp, string nonce, string sign);
|
||
|
||
// === 群组 ===
|
||
GroupRelatedItem[]? GroupRelated(string profileId);
|
||
AppAndProfileItem[]? GroupSearch(string keyword, int skip = 0, int take = 20);
|
||
GroupDetailTreeNode? GroupDetail(string groupId, string profileId);
|
||
string[]? GroupRelatedIndex(string groupId, string profileId);
|
||
|
||
// === Profile ===
|
||
AppAndProfileItem[]? ProfileSearch(string keyword, int skip = 0, int take = 20);
|
||
AppAndProfileItem[]? ProfileList(string[] ids);
|
||
|
||
// === 内部应用专用 ===
|
||
bool CheckIsAppOwner(string profileId, string applicationId);
|
||
AppAndProfileItem[]? GetAppList(string profileId, IEnumerable<string> appIds);
|
||
|
||
// === 登录 ===
|
||
GetCodeResponse GetLoginCode(string? scene = null, Dictionary<string, object>? data = null, string? backUrl = null);
|
||
LoginInfoResponse GetLoginInfo(string code, string? scene = null);
|
||
|
||
// === 安全验证（二次确认） ===
|
||
GetCodeResponse GetConfirmCode(string scene, string userId, Dictionary<string, object>? data = null, string? backUrl = null);
|
||
ConfirmResponse Confirm(string code, string scene, string? userId = null);
|
||
```
|
||
|
||
**GetCodeResponse**: `{ Code, Server, FullUrl }`
|
||
|
||
### 4.4 SimApiAuthIam — IAM 权限管理
|
||
|
||
```csharp
|
||
void RegisterPermissions(PermissionItem[] permissions);
|
||
string[] GetPermissionOwned(string profileId);
|
||
void CheckPermission(string profileId, string permission);
|
||
```
|
||
|
||
**PermissionItem**: `{ Identifier, Name, Group, Description }`
|
||
|
||
### 4.5 SimApiAuthCenterMiddleware — 网关鉴权
|
||
|
||
内部应用专用。解析请求头 `X-SimApi-Gate-Auth` / `X-SimApi-Gate-Time` / `X-SimApi-Gate-Sign`，MD5 验签后将 Base64 解码的用户信息注入 `HttpContext.Items["LoginInfo"]`。
|

|
||
## 5. Attributes 完整参考
|
||
|
||
### [SimApiAuth] — 身份认证
|
||
|
||
```csharp
|
||
[SimApiAuth] // 仅检查登录
|
||
[SimApiAuth("admin")] // 单角色
|
||
[SimApiAuth("admin,manager")] // 逗号分隔 OR 关系
|
||
[SimApiAuth(new[]{"a","b"})] // 数组形式
|
||
```
|
||
- 加在 **Controller 类** 或 **方法** 上
|
||
- **禁止** 代码中手动判断 `LoginInfo.Type.Contains(...)` 做权限控制
|
||
|
||
### [SimApiDoc] — Swagger 文档注解
|
||
|
||
```csharp
|
||
[SimApiDoc("分组名", "接口名称")]
|
||
[SimApiDoc("分组名", "接口名称", "详细描述")]
|
||
[SimApiDoc(new[]{"tag1","tag2"}, "接口名称")]
|
||
```
|
||
|
||
### [SimApiSign] — API 签名验证
|
||
|
||
```csharp
|
||
[SimApiSign(KeyProvider = typeof(MySignProvider))]
|
||
// 签名: MD5(field1=v1&...&appId=xxx×tamp=ts&nonce=nnn&密钥)
|
||
```
|
||
|
||
实现 `SimApiSignProviderBase`：
|
||
```csharp
|
||
public class MySignProvider : SimApiSignProviderBase
|
||
{
|
||
// 可覆盖: AppIdName, TimestampName, NonceName, SignName, QueryExpires(秒), DuplicateRequestProtection, SignFields
|
||
public override string? GetKey(string? appId) { ... }
|
||
}
|
||
```
|
||
|
||
### [AesBody] — AES 解密请求体
|
||
|
||
```csharp
|
||
[AesBody(KeyProvider = typeof(MyAesKeyProvider))] MyRequest req
|
||
// 客户端提交: {"data": "Base64(AES-256-CBC 密文)"}
|
||
```
|
||
|
||
实现 `AesBodyProviderBase`，覆盖 `AppIdName` 和 `GetKey(appId)`。
|
||
|
||
### [SynapseEvent] — MQTT 事件处理
|
||
|
||
```csharp
|
||
[SynapseEvent("order/created")] // 指定 eventName
|
||
[SynapseEvent] // 不指定 = 方法名
|
||
// 参数: 1个(string eventName) / 2个(string eventName, T data)
|
||
// 注意: 至少需要1个参数
|
||
```
|
||
|
||
### [SynapseRpc] — MQTT RPC 方法
|
||
|
||
```csharp
|
||
[SynapseRpc] // 注册名 "ClassName.MethodName"
|
||
[SynapseRpc("customName")] // 自定义名
|
||
// 参数: 0~2个，第2个固定 Dictionary<string,string>(headers)
|
||
```
|
||
|
||
### [OriginResponse] — 跳过响应封装
|
||
|
||
```csharp
|
||
[HttpGet][OriginResponse]
|
||
public string GetRaw() => "raw";
|
||
```
|
||
|
||
---
|
||
|
||
## 6. Swagger 文档 — EnableSimApiDoc
|
||
|
||
```csharp
|
||
options.ConfigureSimApiDoc(doc =>
|
||
{
|
||
doc.DocumentTitle = "接口文档";
|
||
doc.ApiGroups = [new("api", "公共"), new("admin", "管理", "描述可选")];
|
||
doc.SupportedMethod = [SubmitMethod.Post]; // 默认仅POST
|
||
doc.ApiAuth = new SimApiAuthOption { Type = ["SimApiAuth"] }; // 认证方式
|
||
});
|
||
```
|
||
|
||
每组通过 `[ApiExplorerSettings(GroupName = "admin")]` 分类。
|
||
|
||
### 自动过滤器
|
||
|
||
| 过滤器 | 效果 |
|
||
| --------------------------------- | ------------------------------------ |
|
||
| `SimApiResponseOperationFilter` | 返回值包装为 `SimApiBaseResponse<T>` |
|
||
| `SimApiAuthOperationFilter` | 鉴权接口 + Token Header |
|
||
| `SimApiSignOperationFilter` | 签名接口注入签名参数 |
|
||
| `AesBodyOperationFilter` | AES 接口展示原始结构 |
|
||
| `GlobalDynamicObjectSchemaFilter` | object/Dictionary → Schema |
|
||
| `RemoveEmptyTagsFilter` | 清除空分组 |
|
||
|
||
---
|
||
|
||
## 7. 对象存储 — EnableSimApiStorage
|
||
|
||
基于 MinIO SDK（S3 兼容）。

||
|
||
### 配置
|
||
|
||
```csharp
|
||
options.EnableSimApiStorage = true;
|
||
options.ConfigureSimApiStorage(s =>
|
||
{
|
||
s.Endpoint = "http://minio:9000"; // 不能以 / 结尾
|
||
s.AccessKey = "admin";
|
||
s.SecretKey = "pass";
|
||
s.Bucket = "bucket";
|
||
s.ServeUrl = "http://cdn.example.com/bucket"; // 不能以 / 结尾
|
||
});
|
||
```
|
||
|
||
### API
|
||
|
||
```csharp
|
||
GetUploadUrlResponse GetUploadUrl(string path, int expire = 7200);
|
||
// 返回: { UploadUrl, DownloadUrl, Path }
|
||
|
||
string GetDownloadUrl(string path, int expire = 600);
|
||
void UploadFile(string path, Stream stream, string contentType = "image/png");
|
||
string? FullUrl(string? path); // 路径→完整URL
|
||
string? GetUrl(string? path); // 同上
|
||
string? GetPath(string? url); // URL→相对路径
|
||
IMinioClient Client { get; } // 底层 MinIO 客户端
|
||
```
|
||
|
||
> **路径必须以 `/` 开头**
|
||

||
T? Get<T>(string key);
|
||
string? Get(string key);
|
||
bool HasKey(string key);
|
||
void Remove(string key);
|
||
```
|
||
|
||

|
||
```csharp
|
||
options.EnableJob = true;
|
||
options.ConfigureSimApiJob(job =>
|
||
{
|
||
job.DashboardUrl = "/jobs"; // null = 不开启
|
||
job.DashboardAuthUser = "admin";
|
||
job.DashboardAuthPass = "pass";
|
||
job.Database = 1; // Redis DB 编号
|
||
job.Servers = [

new() { Queues = ["default"], WorkerNum = 5 },
|
||
new() { Queues = ["email"], WorkerNum = 2 }
|
||
];
|
||
});
|
||
```
|
||
|
||
```csharp

|
||
|
||
### 配置
|
||
|
||
```csharp
|
||
options.EnableSynapse = true;
|
||
options.ConfigureSimApiSynapse(s =>
|
||
{
|
||
s.Websocket = "ws://mqtt:8083/mqtt";
|
||
s.Username = "user";
|
||
s.Password = "pass";
|
||
s.SysName = "my-system";
|
||
s.AppName = "order-service";
|
||
s.AppId = "instance-001"; // 不填自动GUID
|
||
s.RpcTimeout = 3; // 秒
|
||
s.EventLoadBalancing = false; // $queue 负载均衡
|
||
s.EnableConfigStore = true; // 分布式配置中心
|
||
});
|
||
```
|
||
|
||
### Topic 规则
|
||
|
||
| 用途 | Topic 格式 |
|
||
| -------- | ------------------------------------------------------ |
|
||
| 事件发布 | `{SysName}/event/{AppName}/{eventName}` |
|
||
| 事件订阅 | `{SysName}/event/{eventName}` (或 `$queue/` 前缀) |
|
||
| RPC 请求 | `{SysName}/{targetApp}/rpc/server/{method}` |
|
||
| RPC 响应 | `{SysName}/{callerApp}/rpc/client/{AppId}/{messageId}` |
|
||
| 配置 | `{SysName}/synapse-config-store/{key}` (Retain) |
|
||
|
||
### API
|
||
|
||
```csharp
|
||
// 事件
|
||
bool Event(string eventName, dynamic? param = null);
|
||
|
||
// RPC (同步)
|
||
SimApiBaseResponse<T> Rpc<T>(string appName, string method, dynamic? param = null,
|
||
Dictionary<string, string>? headers = null, int? timeout = null);
|
||
|
||
// RPC 内报错
|
||
void RpcError(int code, string message = "");
|
||
void RpcErrorWhen(bool condition, int code, string message = "");
|
||
|
||
// 分布式配置
|
||
bool SetConfig(string key, string value);
|
||
string? GetConfig(string key);
|
||
```
|
||
|
||
### 处理器扫描（自动注册）
|
||
|
||
带 `[SynapseRpc]` / `[SynapseEvent]` 的类自动扫描注册为 Scoped 服务。

## 13. 工具集 — SimApiUtil
|
||
|
||
```csharp
|
||
DateTime CstNow; // UTC+8

|
||
|
||
string Md5(string src, string mode = "x2"); // x2=32位, x3=48位, x4=64位
|
||
string Sha1(string src, string mode = "x2");
|
||
string Base64Encode(string str);
|
||
string Base64Decode(string base64Str);
|
||
string Base64Encode(object obj);
|
||
T? Base64Decode<T>(string base64Str);
|
||
|
||
string Json(object? obj); // camelCase，中文不转义
|
||
T? FromJson<T>(string json);
|
||
T XmlDeserialize<T>(string xml);
|
||
JsonSerializerOptions JsonOption; // 可复用
|
||
|
||
bool CheckCell(string cell); // 手机号验证
|

## 14. 数据模型 — SimApiBaseModel
|
||
|
||
```csharp
|
||
public class UserEntity : SimApiBaseModel
|
||
{
|
||
// 自动: Id(GUID string), CreatedAt, UpdatedAt
|
||
// 默认忽略映射: Id, CreatedAt, UpdatedAt
|
||
}
|
||
|
||
void MapData<TS>(TS source, bool mapAll = false); // 同名同类型非null属性
|
||
void MapData<TS>(TS source, string[] mapFields); // 指定字段
|
||
void UpdateTime();
|
||
```

## 15. DTO 规范
|
||
|
||
| 类型 | 命名 | 示例 |
|
||
| ---- | ----------------- | ----------------- |
|
||
| 请求 | `[动作]Request` | `UserEditRequest` |
|
||
| 响应 | `[动作]Response` | `TokenResponse` |
|
||
| 载体 | `[含义]Data/Item` | `GenerateData` |
|
||
|
||
### 框架内置 DTO
|
||
|
||
```csharp
|
||
class SimApiStringIdOnlyRequest { required string Id; }
|
||
class SimApiOneFieldRequest<T> { T? Data; }
|
||
class SimApiBasePageRequest { int Page = 1; int Count = 20; }
|
||
class SimApiBaseResponse { int Code; string Message; } // code=200 默认
|
||
class SimApiBaseResponse<T> : SimApiBaseResponse { T? Data; }
|
||
class PageResponse<T> { T? List; int Page; int Count; int Total; }
|
||
```

## 16. SimApiOptions 完整配置
|
||
|
||
```csharp
|
||
builder.Services.AddSimApi(options =>
|
||
{
|
||
options.RedisConfiguration = "localhost:6379";
|
||
|
||
// 功能开关
|
||
options.EnableSimApiAuth = false; // Token 认证
|
||
options.EnableSimApiAuthGate = false; // Auth Center 网关鉴权
|
||
options.EnableSimApiDoc = false; // Swagger 文档
|
||
options.EnableSimApiStorage = false; // S3 存储
|
||
options.EnableJob = false; // Hangfire
|
||
options.EnableSynapse = false; // MQTT
|
||
options.EnableSimApiHttpClient = false; // 外部 HTTP 调用
|
||
options.EnableLogger = true; // 控制台日志
|
||
options.EnableCors = true; // 全量 CORS
|
||
options.EnableSimApiException = true; // 全局异常拦截
|
||
options.EnableSimApiResponseFilter = true; // 响应统一封装
|
||
options.EnableForwardHeaders = true; // 反向代理 Header
|
||
options.EnableLowerUrl = true; // URL 小写
|
||
|
||
// 子模块配置
|
||
options.ConfigureSimApiDoc(doc => { ... });
|
||
options.ConfigureSimApiStorage(s => { ... });
|
||
options.ConfigureSimApiJob(job => { ... });
|
||
options.ConfigureSimApiSynapse(s => { ... });
|
||
options.ConfigureSimApiAuthCenter(gate => { ... });
|
||
options.ConfigureSimApiHttpClient(http => { ... });

## 17. GOTCHAS — 常见错误
|
||
|
||
| ❌ 错误 | ✅ 正确 |
|
||
| ------------------------------------------------------ | ------------------------------------------- |
|
||
| 存储路径 `avatars/file.jpg`（无前导 `/`） | 必须以 **`/`** 开头 |
|
||
| `s.Endpoint = "http://x:9000/"` | **不能以 `/` 结尾** |
|
||
| `synapse.PublishEvent(...)` | 方法名是 **`synapse.Event(...)`** |
|
||
| `synapse.CallRpcAsync(...)` | 方法名是 **`synapse.Rpc<T>(...)`** |
|
||
| HTTP 4xx/5xx 状态码 | 永远 **HTTP 200**，错误在 JSON code |
|
||
| `SupportedMethod` 写多种方法 | 默认仅 **POST** |
|
||
| `SimApiStorageOptions = Configuration.GetSection(...)` | 用 **`ConfigureSimApiStorage(s => {...})`** |
|
||
| 代码中 `LoginInfo.Type.Contains("admin")` | 用 `[SimApiAuth("admin")]` |
|
||
| `return ActionResult<T>` | 直接返回 Entity / void |

|
||
## 18. 禁止事项
|
||
|
||
| ❌ 禁止 | ✅ 正确 |
|
||
| --------------------------------------- | ----------------------------------------------------- |
|
||
| HTTP 4xx/5xx 表达业务错误 | HTTP 200 + JSON `code` |
|
||
| `throw new Exception(msg)` | `ErrorWhen` 或 `throw new SimApiException(code, msg)` |
|
||
| 鉴权 Attribute 只放方法 | 可以放 Controller **类**上 |
|
||
| 手动判断 `LoginInfo.Type.Contains(...)` | `[SimApiAuth("role")]` |
|
||
| Entity 配导航属性 / Fluent API | Convention 自动映射 |
|
||
| 花括号块命名空间 | 文件范围 `namespace X;` |
|
||
| 传统构造函数注入 | 主构造函数 |
|
||
| `new List<T>()` / `new string[]{}` | `[]` 集合表达式 |
|
||
| `Count() > 0` | `Any()` |
|
||
| `ToList()` → 数组 | 直接 `ToArray()` |
|
||
| 全局 catch 吞异常 | 让异常冒泡到 SimApiExceptionMiddleware |
|
