How do I associate a custom MIME-type to my local application in the major browsers?

问题

I want to invent a new mime-type and associate it to a custom application in the browser to enable users to launch my app from a web page. The users of my secure web site are in a closed-environment, meaning this is not a general-purpose, mainstream application - I can configure their browser ahead of time.

Spoon.net does something very similar to enable launching virtualized applications using their mini-kernel plugin.

One of the answers to this question alluded to this method, without details for how to accomplish it.

How do I achieve this in a cross-platform manner on Chrome and IE 8/9? Is there a way to do the mime-type association through browser extensions, either native or through crossrider? How does an app like Adobe Reader or Apple Quicktime achieve this? I want to avoid touching the registry if possible.

What are the risks associated with this method? My site is an intranet web application secured with a certificate and trusted by my users. Any reason I should not go down this path?

EDIT: Apparently this can be achieved in Firefox by manipulating the mimeTypes.rdf file.

EDIT: It looks like JDIC is a Java-based mechanism that could be used for the same thing. Is there a similar non-Java construct? Maybe in Javascript?

回答1:

It looks like it can be done via a registry change on windows.

[HKEY_CLASSES_ROOT\.atom]
    @="atom_file"

[HKEY_CLASSES_ROOT\atom_file]
    @="Atom Syndication Program"

[HKEY_CLASSES_ROOT\atom_file\shell]

[HKEY_CLASSES_ROOT\atom_file\shell\open]

[HKEY_CLASSES_ROOT\atom_file\shell\open\command]
    @="\"C:\\AtomHandler\\handle.exe\" %1"

[HKEY_CLASSES_ROOT\MIME\Database\Content Type\application/atom+xml]
    "Extension"=".atom"

I often want to associate a new file type with being a text file. The safest and quickest way of doing this is:

A. Create the file type in Registry if it doesn't already exist

Windows -> Search for RegistryEditor -> Open
Right-Click HKEY_CLASSES_ROOT -> New -> Key
Name the key the same as the extension (e.g. .txttt)
Click on the newly created key (e.g. HKEY_CLASSES_ROOT -> .txttt) -> Right-click on (Default) in the right pane -> Modify -> Set to the following values:

(Default) REGSZ txtfile

Right-click on the newly created key (e.g. HKEY_CLASSES_ROOT -> .txttt) -> New -> String -> Set to the following values:

ContentType REG_SZ text/plain

Right-click on the newly created key (e.g. HKEY_CLASSES_ROOT -> .txttt) -> New -> String -> Set to the following values:

PerceivedType REG_SZ text

B. Associate the file type with a default program

Right-click on your file -> Open with -> Choose another app
Check "Always use to open with this program"
Select the default program

The new file type should open and preview in Windows Explorer with the default text editor program you selected.
