Bitzsoft.Integrations.ElectronicSignature.Fadada

法大大电子签章服务实现,基于法大大开放平台 V3 API。

功能特性

  • 完整实现 IElectronicSignatureProvider:覆盖合同发起、详情、下载、查看、撤销、签署 URL、签署状态、印章、模板、回调验签全部统一方法
  • 双轮 HMAC-SHA256 签名 + Token 自动管理:首次请求自动获取 Token,内存缓存并在过期前 5 分钟自动刷新,SemaphoreSlim 保证并发安全
  • 回调验签:校验 X-Fadada-Timestamp 时间戳新鲜度(5 分钟)与 X-Fadada-Signature,使用 CryptographicOperations.FixedTimeEquals 安全比较
  • 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="1.0.0" />

配置

{
  "Fadada": {
    "AppId": "your-app-id",
    "AppKey": "your-app-key",
    "BaseUrl": "https://openapi.fadada.com/api/v3/",
    "Timeout": "00:00:30"
  }
}
参数 必填 默认值 说明
AppId 应用标识
AppKey 应用密钥(参与 HMAC-SHA256 签名,不传输)
BaseUrl https://openapi.fadada.com/api/v3/ API 基地址(沙箱 https://uat-openapi.fadada.com/api/v3/
Timeout 00:00:30 HTTP 请求超时(文件上传/下载可调大)
HttpClientName FadadaElectronicSignatureProvider 命名 HttpClient 标识

注册服务

using Bitzsoft.Integrations.ElectronicSignature.Fadada;

// 方式一:IConfiguration(默认读取 "Fadada" 配置节)
services.AddBitzsoftFadadaElectronicSignature(configuration);

或:

using Bitzsoft.Integrations.ElectronicSignature.Fadada;

// 方式二:委托配置
services.AddBitzsoftFadadaElectronicSignature(options =>
{
    options.AppId = "your-app-id";
    options.AppKey = "your-app-key";
    options.BaseUrl = "https://openapi.fadada.com/api/v3/";
});

请求审计

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(configuration);

// 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.MaxInMemoryBodyBytes = 64 * 1024; // 仅控制内存/加密临时文件切换,不截断正文
    opts.SensitiveFields.Add("AppKey");
});
services.AddBitzsoftFadadaElectronicSignature(configuration);

使用示例

统一抽象

// 注入 IElectronicSignatureProvider,ProviderName == "Fadada"
var createResult = await provider.CreateContractAsync(new SimpleContractRequest
{
    Title = "采购合同",
    FileName = "contract.pdf",
    FileData = await File.ReadAllBytesAsync("contract.pdf"),
    SignerName = "张三",
    SignerPhone = "13800000000"
});

var contractId = createResult.Data!;

// 查询详情、获取签署页面、下载合同
var detail  = await provider.GetContractDetailAsync(contractId);
var signUrl = await provider.GetSigningUrlAsync(contractId, "signer-id");
var bytes   = await provider.DownloadContractAsync(contractId);

扩展 API(partial class)

统一接口仅覆盖极简场景,复杂签署任务、账号、组织、模板、印章等通过 FadadaElectronicSignatureProvider 的 partial class 方法调用:

var fadada = (FadadaElectronicSignatureProvider)provider;

// 创建签署任务(复杂场景,多签署方、多文档)
var result = await fadada.QueryPostAsync(FadadaApis.SignTaskCreate, body: new { /* ... */ });

扩展方法按领域拆分:SignTasks(20)、Documents(12)、Accounts(17)、Organizations(17)、Templates(10)、Seals(6)。
