推荐答案

在configure部分中创建FileExtensionContentTypeProvider对象，并为每个MIME类型填充或删除Mapping，如下所示:

Create a FileExtensionContentTypeProvider object in configure section and fill or remove Mapping for each MIME Type as follows:

public void Configure(IApplicationBuilder app) { // Set up custom content types -associating file extension to MIME type var provider = new FileExtensionContentTypeProvider(); // Add new mappings provider.Mappings[".myapp"] = "application/x-msdownload"; provider.Mappings[".htm3"] = "text/html"; provider.Mappings[".image"] = "image/png"; // Replace an existing mapping provider.Mappings[".rtf"] = "application/x-msdownload"; // Remove MP4 videos. provider.Mappings.Remove(".mp4"); app.UseStaticFiles(new StaticFileOptions() { FileProvider = new PhysicalFileProvider( Path.Combine(Directory.GetCurrentDirectory(), @"wwwroot", "images")), RequestPath = new PathString("/MyImages"), ContentTypeProvider = provider }); . . . }
