如何从文件扩展名中获得MIME类型?
当前回答
你可以使用mimemaps类。我认为这是最简单的方法。我也给出了mimemapping的导入。因为我觉得找这些类的导入很麻烦。
import org.springframework.boot.web.server.MimeMappings;
MimeMappings mm=new MimeMappings();
String mimetype = mm.get(fileExtension);
System.out.println(mimetype);
其他回答
您可以在注册表中找到这些信息。例如,.pdf文件的MIME类型可以在键HKEY_CLASSES_ROOT\.pdf中找到,在值"Content type "中:
string mimeType = Registry.GetValue(@"HKEY_CLASSES_ROOT\.pdf", "Content Type", null) as string;
这里提出的两种解决方案的组合:
using System;
using System.Collections.Generic;
namespace Mime
{
class Mime
{
public static string GetMimeType(string fileName)
{
if (string.IsNullOrEmpty(fileName) || string.IsNullOrWhiteSpace(fileName))
{
throw new ArgumentNullException("filename must contain a filename");
}
string extension = System.IO.Path.GetExtension(fileName).ToLower();
if (!extension.StartsWith("."))
{
extension = "." + extension;
}
string mime;
if (_mappings.TryGetValue(extension, out mime))
return mime;
if (GetWindowsMimeType(extension, out mime))
{
_mappings.Add(extension, mime);
return mime;
}
return "application/octet-stream";
}
public static bool GetWindowsMimeType(string ext, out string mime)
{
mime="application/octet-stream";
Microsoft.Win32.RegistryKey regKey = Microsoft.Win32.Registry.ClassesRoot.OpenSubKey(ext);
if (regKey != null)
{
object val=regKey.GetValue("Content Type") ;
if (val != null)
{
string strval = val.ToString();
if(!(string.IsNullOrEmpty(strval)||string.IsNullOrWhiteSpace(strval)))
{
mime=strval;
return true;
}
}
}
return false;
}
static IDictionary<string, string> _mappings = new Dictionary<string, string>(StringComparer.InvariantCultureIgnoreCase) {
#region Big freaking list of mime types
// combination of values from Windows 7 Registry and
// from C:\Windows\System32\inetsrv\config\applicationHost.config
// some added, including .7z and .dat

使用MimeTypeMap包,它提供了文件扩展名到mime类型以及mime类型到文件扩展名的巨大双向映射
使用mimetype;
获取扩展的mime类型
Console.WriteLine("txt -> " + MimeTypeMap.GetMimeType("txt")); // "text/plain"
获取mime类型的扩展名
Console.WriteLine("audio/wav -> " + MimeTypeMap.GetExtension("audio/wav")); // ".wav"

我已经编写了一个程序来获取和转换Apache mime。类型文件到c#字典<字符串,字符串>的关键文件扩展名。这里的。
实际的输出是这个文件(但是您可能希望获取它并再次运行它,以防Apache文件在我上次运行之后已经更新)。
public static Dictionary<string, string> MimeTypes = new Dictionary<string, string>
{
{ "123", "application/vnd.lotus-1-2-3" },
{ "3dml", "text/vnd.in3d.3dml" },
{ "3g2", "video/3gpp2" },
{ "3gp", "video/3gpp" },
{ "7z", "application/x-7z-compressed" },
{ "aab", "application/x-authorware-bin" },
{ "aac", "audio/x-aac" },
{ "aam", "application/x-authorware-map" },
{ "aas", "application/x-authorware-seg" },
{ "abw", "application/x-abiword" },
