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}特色功能示例代码

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;}推荐项目
