. docx、. pptx等的正确MIME类型是什么？

对于较旧的*. doc文档，这就足够了：

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

我应该为新的. docx文档使用什么MIME类型？此外，对于pptx和xlsx文档？

以下是用于HTTP内容流的正确Microsoft Office MIME类型：

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.ppsm     application/vnd.ms-powerpoint.slideshow.macroEnabled.12
.mdb      application/vnd.ms-access

或者，如果您使用的是. NET v4.5或更高版本，请尝试使用#0(yourFileName)来获取MIME类型。它比硬编码字符串好得多。

更新：在. Net Core中，同样可以使用#0实现

要加载. docx文件：

    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")}}

Swift4

 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() {return mimetype as String}}return "application/octet-stream"}

这是一个（几乎）完整的JSON格式文件扩展名的MIME。
您可以执行以下示例：MIME["ppt"]、MIME["docx"]等

根据@刘德华的建议：

  • 将jpeg和jpg MIME分离为两个不同的键
  • 将mp4格式的MIME更新为video/mp4
小开

这篇文章将探讨在各种编程语言中获取MIME类型的各种方法，它们的CONS以单行描述为标题。所以，相应地使用它们和适合你的方法。

例如。当用户可能提供. xls、. xlsx或. xlsm中的任何一个并且您不想为它们中的每一个编写代码测试扩展并提供MIME类型时，下面的代码特别有用。让系统来做这项工作。

python3

使用python-Magic

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

使用内置的mimeypes模块-将文件名映射到MimeTypes模块

>>> 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'

java7

来源：Baeldung关于Java中的文件MIME类型的博客

操作系统依赖

@Testpublic void get_JAVA7_mimetype() {Path path = new File("Employee.xlsx").toPath();String mimeType = Files.probeContentType(path);
assertEquals(mimeType, "application/vnd.ms-excel");}

它将使用FileTypeDetector实现来探测MIME类型，并调用每个实现的probeContentType来解析该类型。因此，如果实现已知文件，则返回内容类型。但是，如果没有发生这种情况，则调用系统默认的文件类型检测器。

使用输入流的前几个字符解决

@Testpublic void getMIMEType_from_Extension(){File file = new File("Employee.xlsx");String mimeType = URLConnection.guessContentTypeFromName(file.getName());
assertEquals(mimeType, "application/vnd.ms-excel");}

使用MIME类型的内置表

@Testpublic void getMIMEType_UsingGetFileNameMap(){File file = new File("Employee.xlsx");FileNameMap fileNameMap = URLConnection.getFileNameMap();String mimeType = fileNameMap.getContentTypeFor(file.getName());
assertEquals(mimeType, "image/png");}

它返回所有URLConnection实例使用的MIME类型矩阵，然后用于解析输入文件类型。然而，当涉及到URLConnection时，这种MIME类型矩阵非常有限。

默认情况下，类使用JRE_HOME/lib中的content-types.properties文件。但是，我们可以通过使用content.types.user.table属性指定用户特定的表来扩展它：

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

解释使用FileReader API获取的Magic Number

当使用javaScript获取基于filestream的MimeType时，最终结果看起来像这样。打开嵌入的jsFiddle来查看和理解这种方法。

奖金：大多数MIME类型都可以访问它，您也可以在获取Mimetype函数中添加自定义Mime类型。此外，它完全支持MS Office文件Mime类型。

文件阅读器API结果

在此示例中计算文件的mime类型的步骤是：

  1. 用户选择一个文件。
  2. 使用文件的前4个字节切片方法。
  3. 创建一个新的FileReader实例
  4. 使用FileReader读取您作为数组缓冲区切片的4个字节。
  5. 由于数组缓冲区只是表示二进制缓冲区的通用方式，我们需要创建一个类型数组，在本例中为Uint8Array。
  6. 在我们的手中有了一个类型数组，我们可以检索每个字节并将其转换为十六进制（通过使用toString（16））。
  7. 我们现在有一种方法可以通过读取前四个字节从文件中获取魔法数字。最后一步是将其映射到真正的mime类型。

浏览器支持（95%以上，在所有现代浏览器中接近100%）：FileReader API

文件读取器API浏览器支持
