[SOLVED] how to check with vobject either string is valid vcard or not when dealing with UTF-8 characters?

how to check with vobject either string is valid vcard or not when dealing with UTF-8 characters?

how to check with vobject either string is valid vcard or not?

Is there some extra method or generall approach with try and catch?

For now I do it as follows:

 try:
            vobj = vobject.readOne(vcard_readable)
 except Exception as e:
            error_message = {
                "valid": False,
                "reason": "Invalid vCard\n{0}".format(e)}

Solution

Your current code works fine, but generally you don't want to catch Exception because this will mask other errors in your code. For example, if I take your code snippet and put it in a file and then run it...I get no error messages, even though I have not imported the vobject module. This is because that code is actually raising a NameError:

Traceback (most recent call last):
  File "foo.py", line 2, in <module>
    vobj = vobject.readOne(vcard_readable)
NameError: name 'vobject' is not defined

but because you're catching all exceptions, you're hiding it. A better technique is to catch only the specific exceptions you expect to receive from the vobject module, and let others percolate up normally.

For vobject, all of the exceptions it raises are going to be subclasses of vobject.base.VObjectError, so the following code would suffice:

 try:
            vobj = vobject.readOne(vcard_readable)
 except vobject.base.VObjectError as e:
            error_message = {
                "valid": False,
                "reason": "Invalid vCard\n{0}".format(e)}
