Hi, I'm new to Calc, and fascinated by its power, but while using "Link
to External Data" to get realtime stock quote, the website asks me to log
in first, would you mind telling me how to type username/password when
importing external data? Thanks. - psist -
I assume that "external data" shall mean "http". In ftp you could use
the "user:[EMAIL PROTECTED]" syntax, not sure if this is possible for http.
Unfortunately not until the CWS webdavandgvfslocking1 which changes
tools/source/fsys/urlobj.cxx to support the user and password for http as
well.
I suppose this CWS is only going to solve HTTP Basic and HTTP Digest
Authentication as per rfc2617. But what about the much more common case
of sites which are using form-based Authentication and than set a cookie
to indicate that the user has been logged in successfully or use a
special redirect URL after a successful login? Is there already a
solution for being able to use such sites with calc in the works as well?
To even extend this idea I could imagine a system where a sequence of
urls must be executed with checking of results between each step before
finally the URL which get´s you the data into calc can be executed. The
external Data Link dialog could than let the user specify such sequence
or even better two such sequences one that is to be executed just once
and one that is to be executed before every update of the data.
Placeholders in the URL which can be replaced by values of calc cells
would be a nice idea there too. Doing so would solve the login problem
as well as enable a bunch of other solutions such as being able to
calculate with the result of a complex website query.
And just one related question: when connecting to http sites does the
UCP for http+webdav maintain state at all at the momment? That is are
cookies set by the server stored and send at the next request? If the
answer to this is yes there might be a possible other solution which
could already work now how to solve the login to
form-based-authentication sites and other problems.
