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 |
是 | — | 应用标识 |
AppKey |
是 | — | 应用密钥(参与 HMAC-SHA256 签名,不传输) |
BaseUrl |
否 | https://openapi.fadada.com/api/v3/ |
API 基地址(沙箱 https://uat-openapi.fadada.com/api/v3/) |
Timeout |
否 | 00:00:30 |
HTTP 请求超时(文件上传/下载可调大) |
HttpClientName |
否 | 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)。
