Bitzsoft.Integrations.FileStorage.Qiniu

七牛云 Kodo 文件存储实现(基于 REST API)。

功能特性

  • 完整实现 IFileStore 接口:覆盖所有文件与存储桶操作
  • 扩展接口 IQiniuFileStore:七牛云 Kodo 文件存储服务标识接口,支持未来扩展
  • 预签名 URL:生成带过期时间的下载地址和上传地址
  • 存储桶管理:创建、删除、判断存储桶是否存在
  • 文件元数据:保存文件时支持设置 ContentType
  • 配置提供器模式:通过 IQiniuConfigProvider 抽象配置获取,支持静态配置或动态配置中心
  • IHttpClientFactory 集成:通过 Microsoft.Extensions.Http 管理 HTTP 连接
  • 无第三方 SDK 依赖:通过 HMAC-SHA1 签名直接调用七牛云 REST API

注册服务

使用 DI 扩展方法(推荐)

using Bitzsoft.Integrations.FileStorage.Qiniu;
using Microsoft.Extensions.DependencyInjection;

var services = new ServiceCollection();

// 注册 HttpClient 工厂
services.AddHttpClient("FileStorage");

// 一行注册七牛云 Kodo 文件存储服务
services.AddBitzsoftQiniuFileStorage(options =>
{
    options.AccessKey = "your-access-key";
    options.SecretKey = "your-secret-key";
    options.DefaultBucketName = "my-app-bucket";
    options.Domain = "http://cdn.example.com";
});

从 IConfiguration 绑定配置

using Bitzsoft.Integrations.FileStorage;
using Bitzsoft.Integrations.FileStorage.Qiniu;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;

var configuration = new ConfigurationBuilder()
    .AddJsonFile("appsettings.json")
    .Build();

var services = new ServiceCollection();

// 注册 HttpClient 工厂(QiniuFileStore 通过 IHttpClientFactory 创建 HTTP 客户端)
services.AddHttpClient("FileStorage");

// 注册处理器工厂
services.AddSingleton<IFileNameProcessorFactory, DefaultFileNameProcessorFactory>();
services.AddSingleton<IBucketNameProcessorFactory, DefaultBucketNameProcessorFactory>();

// 从配置节绑定 QiniuOptions
services.AddSingleton<IQiniuConfigProvider>(sp =>
{
    var options = configuration.GetSection("Qiniu").Get<QiniuOptions>();
    return new QiniuConfigProvider(options);
});

services.AddSingleton<IQiniuFileStore, QiniuFileStore>();
services.AddSingleton<IFileStore>(sp => sp.GetRequiredService<IQiniuFileStore>());

使用 IOptions 模式

using Bitzsoft.Integrations.FileStorage;
using Bitzsoft.Integrations.FileStorage.Qiniu;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;

var services = new ServiceCollection();

services.AddHttpClient("FileStorage");

services.AddSingleton<IFileNameProcessorFactory, DefaultFileNameProcessorFactory>();
services.AddSingleton<IBucketNameProcessorFactory, DefaultBucketNameProcessorFactory>();

// 配置选项
services.Configure<QiniuOptions>(
    configuration.GetSection("Qiniu"));

// QiniuConfigProvider 内部通过 IOptions<QiniuOptions> 获取配置
services.AddSingleton<IQiniuConfigProvider, QiniuConfigProvider>();
services.AddSingleton<IQiniuFileStore, QiniuFileStore>();
services.AddSingleton<IFileStore>(sp => sp.GetRequiredService<IQiniuFileStore>());

第三方请求日志

本连接器基于七牛云 Kodo SDK,HTTP 管道封装在 SDK 内部,无法用 DelegatingHandler 拦截(与 HttpClient 直连实现不同)。请求日志改由 IRequestLogRecorder 回调钩子实现,在对象存储操作包装层记录每次 API 调用,汇入与 HttpClient 拦截同一个日志管道(IRequestLogStore),由宿主统一持久化。

每个对象存储操作产生一条日志记录:

字段 取值
Provider FileStorage.Qiniu
Endpoint Kodo 服务域名(如 s3-cn-east-1.qiniucs.com
Method SDK(非标准 HTTP 方法,标识为 SDK 管道调用)
ApiName 操作名,如 Upload / Download / List / Delete / Exists
RequestBody / ResponseBody 请求/响应摘要序列化(经 SensitiveFields 脱敏)
StatusCode 成功记 200;SDK 抛异常时为空
Exception SDK 异常信息
DurationMs 本次操作耗时

由于 SDK 不暴露原始 HTTP 状态码与响应头,StatusCode 无法像 HttpClient 拦截那样记录真实值(成功记 200、异常时留空),也无法记录 RequestHeaders。此外,仅本连接器已实现的对象存储操作会被记录,SDK 的其他能力(如生命周期、跨域、权限策略等)不在记录范围。

// ① 默认:启用回调但不持久化(日志丢弃)
services.AddBitzsoftQiniuFileStorage(options => { /* ... */ });

// ② 持久化:宿主注册 IRequestLogStore 实现后,对象存储操作自动落库
//    AddBitzsoftQiniuFileStorage 内部已注入 IRequestLogRecorder,宿主无需再额外挂载 handler
services.AddRequestLogging<MyRequestLogStore>(opts =>
{
    opts.MaxBodyLength = 0;               // 下载响应可能很长,0=不截断完整保留
    opts.SensitiveFields.Add("mySecret"); // 额外脱敏字段
});
services.AddBitzsoftQiniuFileStorage(options => { /* ... */ });

自定义 IRequestLogStore 实现(SqlSugar / Dapper / MongoDB)详见 Bitzsoft.Integrations.RequestLogging

使用示例

保存文件并获取下载链接

using Bitzsoft.Integrations.FileStorage;
using Bitzsoft.Integrations.FileStorage.Qiniu;

public class ReportService
{
    private readonly IQiniuFileStore _fileStore;

    public ReportService(IQiniuFileStore fileStore)
    {
        _fileStore = fileStore;
    }

    public async Task<string> UploadReportAsync(Stream pdfStream, string reportName)
    {
        // 保存 PDF 到默认存储桶
        var result = await _fileStore.SaveFileAsync(
            pdfStream, $"{reportName}.pdf");

        // 生成 12 小时有效的下载链接
        var downloadUrl = await _fileStore.GenerateDownloadUrlAsync(
            result.FilePath);

        return downloadUrl;
    }
}

通过 IFileStore 抽象使用

using Bitzsoft.Integrations.FileStorage;

public class ContractService
{
    private readonly IFileStore _fileStore;

    public ContractService(IFileStore fileStore)
    {
        _fileStore = fileStore;
    }

    public async Task<FileResult> UploadContractAsync(
        Stream contractStream, string contractId)
    {
        var args = new SaveFileArgs($"{contractId}.pdf", contractStream)
        {
            ContentType = "application/pdf"
        };

        return await _fileStore.SaveFileAsync(args);
    }
}

从远程 URL 拉取文件到七牛云 Kodo

using Bitzsoft.Integrations.FileStorage;
using Bitzsoft.Integrations.FileStorage.Qiniu;

public class MediaSyncService
{
    private readonly IFileStore _fileStore;

    public MediaSyncService(IFileStore fileStore)
    {
        _fileStore = fileStore;
    }

    public async Task<FileResult> SyncExternalImageAsync(string imageUrl, string saveAs)
    {
        var args = new SaveFileByUrlArgs(saveAs, imageUrl)
        {
            BucketName = "media-assets"
        };

        return await _fileStore.SaveFileByUrlAsync(args);
    }
}

复制与移动文件

using Bitzsoft.Integrations.FileStorage;
using Bitzsoft.Integrations.FileStorage.Qiniu;

public class FileOrganizer
{
    private readonly IFileStore _fileStore;

    public FileOrganizer(IFileStore fileStore)
    {
        _fileStore = fileStore;
    }

    public async Task ArchiveFileAsync(string sourceFile, string archivePath)
    {
        // 复制文件到归档路径
        await _fileStore.CopyFileAsync(sourceFile, archivePath);

        // 删除原文件(等同于 MoveFileAsync)
        await _fileStore.DeleteFileAsync(sourceFile);
    }

    public async Task MoveToBucketAsync(
        string fileName, string sourceBucket, string destBucket)
    {
        var sourceArgs = new FileStorageArgs(fileName) { BucketName = sourceBucket };
        var destArgs = new FileStorageArgs(fileName) { BucketName = destBucket };

        await _fileStore.MoveFileAsync(sourceArgs, destArgs);
    }
}
