Что такое правильный тип mime для docx, pptx и т.д.?

Для более старых документов .doc этого было достаточно:

header("Content-Type: application/msword");

Какой тип mime следует использовать для новых документов docx? Также для документов pptx и xlsx?

Ответ 1

Вот правильные типы Microsoft Office MIME для потоковой передачи содержимого HTTP:

Extension MIME Type
.doc      application/msword
.dot      application/msword

.docx     application/vnd.openxmlformats-officedocument.wordprocessingml.document
.dotx     application/vnd.openxmlformats-officedocument.wordprocessingml.template
.docm     application/vnd.ms-word.document.macroEnabled.12
.dotm     application/vnd.ms-word.template.macroEnabled.12

.xls      application/vnd.ms-excel
.xlt      application/vnd.ms-excel
.xla      application/vnd.ms-excel

.xlsx     application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
.xltx     application/vnd.openxmlformats-officedocument.spreadsheetml.template
.xlsm     application/vnd.ms-excel.sheet.macroEnabled.12
.xltm     application/vnd.ms-excel.template.macroEnabled.12
.xlam     application/vnd.ms-excel.addin.macroEnabled.12
.xlsb     application/vnd.ms-excel.sheet.binary.macroEnabled.12

.ppt      application/vnd.ms-powerpoint
.pot      application/vnd.ms-powerpoint
.pps      application/vnd.ms-powerpoint
.ppa      application/vnd.ms-powerpoint

.pptx     application/vnd.openxmlformats-officedocument.presentationml.presentation
.potx     application/vnd.openxmlformats-officedocument.presentationml.template
.ppsx     application/vnd.openxmlformats-officedocument.presentationml.slideshow
.ppam     application/vnd.ms-powerpoint.addin.macroEnabled.12
.pptm     application/vnd.ms-powerpoint.presentation.macroEnabled.12
.potm     application/vnd.ms-powerpoint.template.macroEnabled.12

Ответ 2

В качестве альтернативы, если вы работаете в .Net v4.5 или выше, попробуйте использовать System.Web.MimeMapping.GetMimeMapping (yourFileName), чтобы получить MIME-типы - намного лучше, чем строки жесткого кодирования

Ответ 3

Вот (почти) завершить все расширения файлов MIME в формате JSON. Просто сделайте пример: MIME ["ppt"], MIME ["docx"] и т.д.

Ответ 4

В этом сообщении будут рассмотрены различные подходы к выбору типа MIME на разных языках программирования с их CONS в однострочном описании как заголовок. Поэтому используйте их соответственно и ту, которая работает для вас.

Напр. код ниже особенно полезен, когда пользователь может предоставить любой из.xls,.xlsx или.xlsm, и вы не хотите писать расширение тестирования кода и поставлять MIME-тип для каждого из них. Пусть система выполнит эту работу.

Python 3

Использование python-magic

>>> pip install python-magic
>>> import magic
>>> magic.from_file("Employee.pdf", mime=True)
'application/pdf'

Использование встроенного модуля mimeypes - Отображение имен файлов в модулях MimeTypes

>>> import mimetypes
>>> mimetypes.init()
>>> mimetypes.knownfiles
['/etc/mime.types', '/etc/httpd/mime.types', ... ]
>>> mimetypes.suffix_map['.tgz']
'.tar.gz'
>>> mimetypes.encodings_map['.gz']
'gzip'
>>> mimetypes.types_map['.tgz']
'application/x-tar-gz'

JAVA 7

Источник: блог Baeldung в файлах MIME-типов в Java

Операционная система зависит

@Test
public void get_JAVA7_mimetype() {
    Path path = new File("Employee.xlsx").toPath();
    String mimeType = Files.probeContentType(path);

    assertEquals(mimeType, "application/vnd.ms-excel");
}

Он будет использовать реализации FileTypeDetector для проверки типа MIME и вызывает метод probeContentType для каждой реализации для разрешения типа. Следовательно, если файл известен реализациям, возвращается тип содержимого. Однако, если это не происходит, вызывается детектор типа файла по умолчанию.


Разрешить использование первых нескольких символов входного потока

@Test
public void getMIMEType_from_Extension(){
    File file = new File("Employee.xlsx");
    String mimeType = URLConnection.guessContentTypeFromName(file.getName());

    assertEquals(mimeType, "application/vnd.ms-excel");
}

Использование встроенной таблицы типов MIME

@Test
public void getMIMEType_UsingGetFileNameMap(){
    File file = new File("Employee.xlsx");
    FileNameMap fileNameMap = URLConnection.getFileNameMap();
    String mimeType = fileNameMap.getContentTypeFor(file.getName());

    assertEquals(mimeType, "image/png");
}

Он возвращает матрицу типов MIME, используемых всеми экземплярами URLConnection, которая затем используется для разрешения типа входного файла. Однако эта матрица типов MIME очень ограничена, когда дело доходит до URLConnection.

По умолчанию класс использует файл content-types.properties в JRE_HOME/lib. Мы можем, однако, расширить его, указав пользовательскую таблицу, используя свойство content.types.user.table:

System.setProperty("content.types.user.table","<path-to-file>");

JavaScript

Источник: FileReader API & Средняя статья об использовании Магических чисел в JavaScript для получения типов Mime

Интерпретировать значение Magic Number с помощью API FileReader

Окончательный результат выглядит примерно так, когда вы используете javaScript для извлечения MimeType на основе фильтра. Откройте встроенный jsFiddle, чтобы увидеть и понять этот подход.

Бонус: он доступен для большинства типов MIME, а также вы можете добавлять пользовательские типы Mime в функцию getMimetype. Кроме того, у него есть ПОЛНАЯ ПОДДЕРЖКА для MIM-типов файлов MS Office.

FileReader API Result

Шаги для вычисления типа mime для файла в этом примере:

  1. Пользователь выбирает файл.
  2. Возьмите первые 4 байта файла, используя метод среза.
  3. Создайте новый экземпляр FileReader
  4. Используйте FileReader для чтения 4 байтов, вырезанных в виде буфера массива.
  5. Поскольку буфер массива - всего лишь общий способ представления двоичного буфера, нам нужно создать TypedArray, в данном случае Uint8Array.
  6. С помощью TypedArray мы можем получить каждый байт и преобразовать его в шестнадцатеричный (используя toString (16)).
  7. Теперь у нас есть способ получить магические числа из файла, читая первые четыре байта. Последний шаг - сопоставить его с реальным типом mime.
