对于像odt,ppt,pptx,xlsx等文档,我需要获取iana.org MediaType而不是application/zip或application/x-tika-msoffice.
如果你看一下mimetypes.xml,那么mimeType元素由iana.org mime-type和"sub-class-of"组成.
<mime-type type="application/msword">
<alias type="application/vnd.ms-word"/>
............................
<glob pattern="*.doc"/>
<glob pattern="*.dot"/>
<sub-class-of type="application/x-tika-msoffice"/>
</mime-type>
如何获取iana.org mime-type名称而不是父类型名称？
在测试mime类型检测时,我做:
MediaType mediaType = MediaType.parse(tika.detect(inputStream));
String mimeType = mediaType.getSubtype();
检测结果 :
FAILED: getsCorrectContentType("application/vnd.ms-excel", docs/xls/en.xls)
java.lang.AssertionError: expected:<application/vnd.ms-excel> but was:<x-tika-msoffice>
FAILED: getsCorrectContentType("vnd.openxmlformats-officedocument.spreadsheetml.sheet", docs/xlsx/en.xlsx)
java.lang.AssertionError: expected:<vnd.openxmlformats-officedocument.spreadsheetml.sheet> but was:<zip>
FAILED: getsCorrectContentType("application/msword", doc/en.doc)
java.lang.AssertionError: expected:<application/msword> but was:<x-tika-msoffice>
FAILED: getsCorrectContentType("application/vnd.openxmlformats-officedocument.wordprocessingml.document", docs/docx/en.docx)
java.lang.AssertionError: expected:<application/vnd.openxmlformats-officedocument.wordprocessingml.document> but was:<zip>
FAILED: getsCorrectContentType("vnd.ms-powerpoint", docs/ppt/en.ppt)
java.lang.AssertionError: expected:<vnd.ms-powerpoint> but was:<x-tika-msoffice>
有没有办法从mimetypes.xml获取实际的子类型？而不是x-tika-msoffice或application/zip？
此外,我从来没有获得application/x-tika-ooxml,但xlsx,docx,pptx文件的应用程序/ zip.
