Any example to display jpegPhoto?

[Zhang H. <zhb...@gm...>]

Hi, list.

Is there ny example to display jpegPhoto stored in LDAP as base64 format?
I only found example to add jpegPhoto in python-ldap-2.3.8/Demo/simple.py.

Thanks very much. :)

Not sure what you really want to display and where.

How about entry['jpegPhoto'][0].encode('base64') ?

Or are you talking about LDIF? Then use module ldif which automagically
base64-encodes NON-ASCII values.

Ciao, Michael.

Thanks Michael :)

Just display the jpegPhoto on web page, not LDIF. :)

I got encoded string after 'entry['jpegPhoto'][0].encode('base64') ',
but how to convert it to a image file and use '<img> tag in HTML to
display it?

entry['jpegPhoto'][0] is the raw binary JPEG data. You can send this
directly to the browser in the body of a HTTP response with MIME-type
image/jpeg. This is kind of off-topic here since it's rather related to
web app programming. So I'd recommend to ask in the forum related to the
web app framework you're using.

Ciao, Michael.

Forget to say, it works in non-IE browsers like this:
----
<img src="data:image/jpeg;base64,**** output of 
entry['jpegPhoto'][0].encode('base64') here ****" />
----

You would have a tag such as <img src="jpegphoto.cgi?user=someone"> where
jpegphoto.cgi is a CGI script that outputs "Content-type: image/jpeg"
followed by the JPEG data.

But that is an HTTP topic so you should probably consult a Python/CGI
resource.

Solved, thanks all :)

I use webpy framework, solved just like Ryan Lovett said.

Still confused what data type it stored in LDAP.
Already base64 encoded?

Display entry['jpegPhoto'][0] directly, got error msg:
----
'ascii' codec can't decode byte 0x89 in position 0: ordinal not in 
range(128)
----

How can i display it if i use 'content-type: image/jpeg' header?

Please read my e-mails more carefully.

As said in <4A2...@st...> it's the raw binary JPEG
image data.

Send the binary data directly. Don't try to (implicitly) convert
entry['jpegPhoto'][0] to a Unicode object. You might want to learn a bit
more about normal strings vs. Unicode objects, string coercion and how
to interpret exceptions like the one above before going any further.
