建议开发环境
操作系统：Windows 10 1903及以上版本 开发工具：VisualStudio2019 v16.5及以上版本 SDK：.Net Core 3.1.0及以上版本
安装程序包
.NET Framework ≥4.6.1
代码语言：javascript复制PM> Install-Package Masuit.Tools.Net.NET Core 2.x/3.x
代码语言：javascript复制PM> Install-Package Masuit.Tools.Core为工具库注册配置
工具库需要用到外部配置节：
- EmailDomainWhiteList，邮箱校验需要用到的白名单域名，英文逗号分隔，每个元素支持正则表达式，若未配置，则不启用邮箱校验白名单
- EmailDomainBlockList，邮箱校验需要用到的黑名单域名，英文逗号分隔，每个元素支持正则表达式，且黑名单优先级高于白名单，若未配置，则不启用邮箱校验黑白名单
- BaiduAK，获取IP/地理位置相关百度云APIKey，若未配置，则无法调用GetIPLocation以及GetPhysicalAddress相关方法
public Startup(IConfiguration configuration)
{
configuration.AddToMasuitTools(); // 若未调用，则默认自动尝试加载appsettings.json

在ASP.NET Core中通过MVC/WebAPI应用程序传输文件数据时使用断点续传以及多线程下载支持。
它提供了ETag标头以及Last-Modified标头。 它还支持以下前置条件标头：If-Match，If-None-Match，If-Modified-Since，If-Unmodified-Since，If-Range。
支持 ASP.NET Core 2.0
从.NET Core2.0开始，ASP.NET Core内部支持断点续传。 因此只是对FileResult做了一些扩展。 只留下了“Content-Disposition” Inline的一部分。 所有代码都依赖于基础.NET类。
如何使用
.NET Framework
在你的控制器中，你可以像在FileResult一样的方式使用它。
using Masuit.Tools.Mvc;
using Masuit.Tools.Mvc.ResumeFileResult;private readonly MimeMapper mimeMapper=new MimeMapper(); // 推荐使用依赖注入
public ActionResult ResumeFileResult()
{
var path = Server.MapPath("~/Content/test.mp4");
return new ResumeFileResult(path, mimeMapper.GetMimeFromPath(path), Request);
}
public ActionResult ResumeFile()
{
return this.ResumeFile("~/Content/test.mp4", mimeMapper.GetMimeFromPath(path), "test.mp4");
}
public ActionResult ResumePhysicalFile()
{
return this.ResumePhysicalFile(@"D:/test.mp4", mimeMapper.GetMimeFromPath(@"D:/test.mp4"), "test.mp4");
}Asp.Net Core
要使用ResumeFileResults，必须在Startup.cs的ConfigureServices方法调用中配置服务：
using Masuit.Tools.AspNetCore.ResumeFileResults.Extensions;public void ConfigureServices(IServiceCollection services)
{
services.AddResumeFileResult();
}然后在你的控制器中，你可以像在FileResult一样的方式使用它。
using Masuit.Tools.AspNetCore.ResumeFileResults.Extensions;private const string EntityTag = ""TestFile"";
private readonly IHostingEnvironment _hostingEnvironment;
private readonly DateTimeOffset _lastModified = new DateTimeOffset(2016, 1, 1, 0, 0, 0, TimeSpan.Zero);
/// <summary>
///
/// </summary>
/// <param name="hostingEnvironment"></param>
public TestController(IHostingEnvironment hostingEnvironment)
{
_hostingEnvironment = hostingEnvironment;
}
[HttpGet("content/{fileName}/{etag}")]
public IActionResult FileContent(bool fileName, bool etag)
{
string webRoot = _hostingEnvironment.WebRootPath;
var content = System.IO.File.ReadAllBytes(Path.Combine(webRoot, "TestFile.txt"));
ResumeFileContentResult result = this.ResumeFile(content, "text/plain", fileName ? "TestFile.txt" : null, etag ? EntityTag : null);
result.LastModified = _lastModified;
return result;
}
[HttpGet("content/{fileName}")]
public IActionResult FileContent(bool fileName)
{
string webRoot = _hostingEnvironment.WebRootPath;
var content = System.IO.File.ReadAllBytes(Path.Combine(webRoot, "TestFile.txt"));
var result = new ResumeFileContentResult(content, "text/plain")
{
FileInlineName = "TestFile.txt",
LastModified = _lastModified
};
return result;
}
[HttpHead("file")]
public IActionResult FileHead()
{
ResumeVirtualFileResult result = this.ResumeFile("TestFile.txt", "text/plain", "TestFile.txt", EntityTag);
result.LastModified = _lastModified;
return result;
}
[HttpPut("file")]
public IActionResult FilePut()
{
ResumeVirtualFileResult result = this.ResumeFile("TestFile.txt", "text/plain", "TestFile.txt", EntityTag);
result.LastModified = _lastModified;
return result;
}
[HttpGet("stream/{fileName}/{etag}")]
public IActionResult FileStream(bool fileName, bool etag)
{
string webRoot = _hostingEnvironment.WebRootPath;
FileStream stream = System.IO.File.OpenRead(Path.Combine(webRoot, "TestFile.txt"));
ResumeFileStreamResult result = this.ResumeFile(stream, "text/plain", fileName ? "TestFile.txt" : null, etag ? EntityTag : null);
result.LastModified = _lastModified;
return result;
}
[HttpGet("stream/{fileName}")]
public IActionResult FileStream(bool fileName)
{
string webRoot = _hostingEnvironment.WebRootPath;
FileStream stream = System.IO.File.OpenRead(Path.Combine(webRoot, "TestFile.txt"));
var result = new ResumeFileStreamResult(stream, "text/plain")
{
FileInlineName = "TestFile.txt",
LastModified = _lastModified
};
return result;
}
[HttpGet("physical/{fileName}/{etag}")]
public IActionResult PhysicalFile(bool fileName, bool etag)
{
string webRoot = _hostingEnvironment.WebRootPath;
ResumePhysicalFileResult result = this.ResumePhysicalFile(Path.Combine(webRoot, "TestFile.txt"), "text/plain", fileName ? "TestFile.txt" : null, etag ? EntityTag : null);
result.LastModified = _lastModified;
return result;
}
[HttpGet("physical/{fileName}")]
public IActionResult PhysicalFile(bool fileName)
{
string webRoot = _hostingEnvironment.WebRootPath;
var result = new ResumePhysicalFileResult(Path.Combine(webRoot, "TestFile.txt"), "text/plain")
{
FileInlineName = "TestFile.txt",
LastModified = _lastModified
};
return result;
}
[HttpGet("virtual/{fileName}/{etag}")]
public IActionResult VirtualFile(bool fileName, bool etag)
{
ResumeVirtualFileResult result = this.ResumeFile("TestFile.txt", "text/plain", fileName ? "TestFile.txt" : null, etag ? EntityTag : null);
result.LastModified = _lastModified;
return result;
}以上示例将为您的数据提供“Content-Disposition：attachment”。 当没有提供fileName时，数据将作为“Content-Disposition：inline”提供。
另外，它可以提供ETag和LastModified标头。
[HttpGet("virtual/{fileName}")]
public IActionResult VirtualFile(bool fileName)
{
var result = new ResumeVirtualFileResult("TestFile.txt", "text/plain")
{
FileInlineName = "TestFile.txt",
LastModified = _lastModified
};
return result;
