Bitzsoft.Integrations.ElectronicSignature.Fadada

法大大电子签章集成。

功能特性

  • 完整实现 IElectronicSignatureProvider 接口：覆盖合同发起、详情、下载、签署 URL、撤销、印章、模板、回调验签全部统一方法
  • partial class 扩展：通过部分类暴露法大大全部 API（签署任务、文档、账号、组织、模板、印章）

安装

dotnet add package Bitzsoft.Integrations.ElectronicSignature.Fadada

<PackageReference Include="Bitzsoft.Integrations.ElectronicSignature.Fadada" Version="*" />

认证方式

双轮 HMAC-SHA256 签名 + Token 自动管理：

  1. SHA256(sortedParams) → signText
  2. HMAC-SHA256(key=appKey, msg=timestamp) → secretSigning
  3. HMAC-SHA256(key=secretSigning, msg=signText) → signature

Token 首次请求自动获取，缓存在内存中，过期前 5 分钟自动刷新。使用 SemaphoreSlim 保证并发安全。

配置

{
  "Fadada": {
    "AppId": "your-app-id",
    "AppKey": "your-app-key",
    "BaseUrl": "https://openapi.fadada.com/api/v3/"
  }
}
配置项 说明 默认值
AppId 应用标识 —
AppKey 应用密钥（HMAC-SHA256） —
BaseUrl API 基地址 https://openapi.fadada.com/api/v3/
Timeout 请求超时 30s
HttpClientName 命名 HttpClient FadadaElectronicSignatureProvider

注册

services.AddBitzsoftFadadaElectronicSignature(options =>
{
    options.AppId = "your-app-id";
    options.AppKey = "your-app-key";
});

第三方请求日志

内置 Bitzsoft.Integrations.RequestLogging 出站请求记录管道，默认 NullRequestLogStore 不持久化。

// ① 默认：启用记录管道但不持久化（日志丢弃）
services.AddBitzsoftFadadaElectronicSignature(options => { /* ... */ });

// ② 持久化：宿主注册 IRequestLogStore 实现后，所有出站请求自动落库
services.AddRequestLogging<MyRequestLogStore>(opts =>
{
    opts.MaxBodyLength = 8192;
    opts.SensitiveFields.Add("mySecret");
});
services.AddBitzsoftFadadaElectronicSignature(options => { /* ... */ });

回调验签

回调 headers 包含 X-Fadada-Timestamp 和 X-Fadada-Signature。VerifyCallback 校验时间戳新鲜度（5 分钟），使用 CryptographicOperations.FixedTimeEquals 安全比较。

扩展方法（partial class）

  • SignTasks — 签署任务创建、签署 URL、撤销、催签、批量签署等（20 方法）
  • Documents — 文档上传、下载、模板创建、签名验证等（12 方法）
  • Accounts — 个人/企业账号管理、第三方用户、OAuth2 授权等（17 方法）
  • Organizations — 子公司/员工管理、修订任务等（17 方法）
  • Templates — 模板上传、编辑、删除、控件管理等（10 方法）
  • Seals — 企业印章增删查、授权管理等（6 方法）
