问题 I was writing a Java program to download attachments from POP3 email. Originally I do this with getting an input stream of a MimePart if its content type is validated. And then I can simply write the input stream into a local file through a FileOutputStream. However, one thing I encountered is that, after I received an email with an attached file as its only content and access it, the mail (of type Message) only consists of a single part, which is of type text/plain. And its content consists

阅读更多关于 Check if a browser supports a specific MIME type?

问题 How can i check if the browser supports a specific mime type with php? 回答1: You could analyze the Accept header field to see if the type or a superset of that type is listed.

阅读更多关于 What is the correct MIME type for a font file?

问题 I have not been able to find a canonical source that indicates the correct MIME type for any and/or each type of file format. All the sources that I have found appear to contradict each other and/or the IANA MIME type RFCs and their associated list. While I am particularly interested in .otf (OpenType) and .ttf (TrueType) file types , an ideal answer would provide a canonical resource for determining the MIME types for a broad spectrum of font file formats, such as those listed on the Font
