Каков правильный тип пантомимы для docx, pptx и т. Д.?

Для более старых документов *.doc этого было достаточно:

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

Какой тип MIME я должен использовать для новых документов DOCX? Также для документов pptx и xlsx?

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

В этом посте будут рассмотрены различные подходы выборки MIME-типов для разных языков программирования с их CONS в однострочном описании в качестве заголовка. Итак, используйте их соответственно и тот, который работает для вас.

Например, приведенный ниже код особенно полезен, когда пользователь может предоставить любой из.xls,.xlsx или.xlsm, и вы не хотите писать расширение для тестирования кода и указывать MIME-тип для каждого из них. Пусть система сделает 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 - сопоставление имен файлов с модулями 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 о типах файлов MIME в Java

Зависит от операционной системы

@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 будет вызывать probeContentType каждой реализации для определения типа. Следовательно, если файл известен реализациям, тогда возвращается тип контента. Однако, если этого не происходит, вызывается системный детектор типов файлов по умолчанию.


Решить, используя первые несколько 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. Однако мы можем расширить его, указав таблицу для конкретного пользователя с помощью свойства content.types.user.table:

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

JavaScript

Источник: FileReader API и статья Medium об использовании магических чисел в JavaScript для получения типов Mime

Интерпретировать магическое число, полученное с помощью API FileReader

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

Бонус: он доступен для большинства типов MIME, а также вы можете добавить пользовательские типы Mime в функцию getMimetype. Кроме того, он имеет полную поддержку для Mime файлов MS Office.

Шаги для вычисления MIME-типа для файла в этом примере:

  1. Пользователь выбирает файл.
  2. Возьмите первые 4 байта файла, используя метод среза.
  3. Создать новый экземпляр FileReader
  4. Используйте FileReader для чтения 4 байтов, которые вы вырезали как буфер массива.
  5. Поскольку буфер массива - это просто общий способ представления двоичного буфера, нам нужно создать TypedArray, в данном случае Uint8Array.
  6. Имея TypedArray в наших руках, мы можем извлечь каждый байт и преобразовать его в шестнадцатеричный (используя toString(16)).
  7. Теперь у нас есть способ получить магические числа из файла, прочитав первые четыре байта. Последний шаг - сопоставить его с реальным типом пантомимы.

 func mimeTypeForPath(path: String) -> String {
        let url = NSURL(fileURLWithPath: path)
        let pathExtension = url.pathExtension

        if let uti = UTTypeCreatePreferredIdentifierForTag(kUTTagClassFilenameExtension, pathExtension! as NSString, nil)?.takeRetainedValue() {
            if let mimetype = UTTypeCopyPreferredTagWithClass(uti, kUTTagClassMIMEType)?.takeRetainedValue() {

            }
        }

    }

Просто посмотрите MDN Web Docs.

Вот список типов MIME, связанных по типу документов, упорядоченных по их общим расширениям:

Общие типы MIME

Загрузить файл.docx

    if let htmlFile = Bundle.main.path(forResource: "fileName", ofType: "docx") {
        let url = URL(fileURLWithPath: htmlFile)
        do{
            let data = try Data(contentsOf: url)
            self.webView.load(data, mimeType: "application/vnd.openxmlformats-officedocument.wordprocessingml.document", textEncodingName: "UTF-8", baseURL: url)
        }catch{
            print("errrr")
        }
    }
      application/vnd.openxmlformats-officedocument.spreadsheetml.sheet

но если у вас (или вашего клиента) есть WPS, возможно, вам нужно добавить

      application/wps-office.xlsx

Когда мы работаем с типом мультимедиа (также известным как многоцелевые расширения электронной почты или MIME-тип), это стандарт, который указывает на природу и формат документа, файла или набора байтов.

За все официальные типы MIME отвечает Internet Assigned Numbers Authority (IANA), и вы можете найти самый последний и полный список на их странице Media Types. Вы можете найти полный список типов MIME по этой ссылке.

Когда наши браузеры используют тип MIME, а не расширение файла, чтобы определить, как обрабатывать URL-адрес, поэтому важно, чтобы веб-серверы отправляли правильный тип MIME в заголовке Content-Type ответа. Если это неправильно настроено, браузеры могут неправильно интерпретировать содержимое файлов, и сайты не будут работать правильно, а загруженные файлы могут быть неправильно обработаны.

В следующей таблице приведены типы HTTP MIME, доступные при работе с документами Office:
