MVC GetImage

Revision as of 06:57, 16 March 2023

With MVC, we have a controller GetImage that expects an object identity and an attribute with a Blob, like this: http://localhost:5052/Turnkey/GetImage?img=9!10-SomeImage

You may append yet another section with '-' that denotes a contenttype header to send to the browser:

http://localhost:5052/Turnkey/GetImage?img=9!10-SomeImage-application%2Fpdf will use application/pdf as content type.

This controller may be used by Angular views as well, if you want to construct a link to download a file or something without actually having the attribute loaded (if it is marked as delayed fetch).

New: Now you can return Text content this way too.

New: For security concerns, use the AllowMVCAccess tagged value on the attribute: this is default "ok" for byte[] (to be backward compatible) and default "notok" for strings - you can also set "okwhenauthenticated". No accessgroup evaluation is provided for GetImage.

See also The_ExternalId_explained to create a more long-lived link.
