Bitzsoft.Integrations.LegalDatabase.Metalaw

MetaLaw 法规案例库 SSO 跳转集成 — 基于国密 SM3 签名生成单点登录访问链接。

功能特性

  • SM3 签名 SSO：构造参数 → 按属性名字典序拼接 → SM3 哈希签名 → JSON + Base64 + URL 编码 → 拼接登录 URL
  • 国密算法：内置 Sm3Helper（基于 BouncyCastle）提供 SM3 摘要算法
  • 本地签名无 HTTP：签名与拼接完全在本地完成，不发起外部 HTTP 请求
  • 统一接口：实现 ILegalDatabaseProvider，与其他法律数据库供应商无缝替换

安装

.NET CLI

dotnet add package Bitzsoft.Integrations.LegalDatabase.Metalaw

PackageReference

<PackageReference Include="Bitzsoft.Integrations.LegalDatabase.Metalaw" Version="1.0.0" />

配置

appsettings.json

{
  "LegalDatabase": {
    "Metalaw": {
      "BaseUrl": "https://meta.law/",
      "AppId": "your-app-id",
      "SecretKey": "your-secret-key",
      "LoginUrl": "https://meta.law/api/open/login"
    }
  }
}
配置项 说明 必填
BaseUrl MetaLaw 基础 URL（默认 https://meta.law/） 否
AppId MetaLaw 分配的应用 ID 是
SecretKey MetaLaw 分配的密钥（用于 SM3 签名） 是
LoginUrl 登录接口 URL（默认 https://meta.law/api/open/login） 否

注册服务

从 IConfiguration 绑定（推荐）

using Bitzsoft.Integrations.LegalDatabase.Metalaw;

builder.Services.AddBitzsoftMetalawLegalDatabase(
    builder.Configuration.GetSection("LegalDatabase:Metalaw"));

委托配置

builder.Services.AddBitzsoftMetalawLegalDatabase(options =>
{
    options.AppId = "your-app-id";
    options.SecretKey = "your-secret-key";
});

使用示例

using Bitzsoft.Integrations.LegalDatabase;

public class LoginController : ControllerBase
{
    private readonly ILegalDatabaseProvider _provider;

    public LoginController(ILegalDatabaseProvider provider) => _provider = provider;

    [HttpGet("login/metalaw")]
    public async Task<IActionResult> Login(string userId)
    {
        var access = await _provider.GenerateAccessUrlAsync(userId);
        // access.Url 形如:
        // https://meta.law/api/open/login?p=<Base64 编码的 JSON 载荷>
        return Redirect(access.Url);
    }
}

签名流程：

  1. 构造参数对象 { uid, appId, nickName, timestamp }
  2. 按属性名字典序拼接 key=value，追加 secretKey={SecretKey}
  3. 对拼接字符串计算 SM3 哈希作为 sign
  4. 将 sign 加入对象，JSON 序列化 → Base64 → URL 编码
  5. 拼接最终 URL {LoginUrl}?p={encoded}

MetaLaw 仅支持 SSO 跳转（AccessUrl），调用 SearchAsync / GetDocumentAsync 会抛出 NotSupportedException。

请求审计

MetaLaw 为本地 SM3 签名，不发起外部 HTTP 请求，无需 RequestLogging 出站请求记录。
