Story Points:


dates containing "+00:00" for timezone encoded to "%2B00:00" are causing the fromDate (toDate) filtering to fail.


(dataone escapes '+' to avoid overloaded semantics with URLEncoder where space becomes '+'

see d1_common_java: for decoding

#2 Updated by Ben Leinfelder almost 9 years ago

Metacat seems to be handling these %2B encodings correctly. It does not like the "+" used directly in the URL because that indicates a space " " and so the UTC date parsing fails.
My hunch is that when routing through the CN proxy this gets confused on it's way to Metacat.

#3 Updated by Ben Leinfelder almost 9 years ago

So the proxy seems to take the "+"
I wonder if it encodes this before passing it to Metacat so that Metacat receives the correctly encoded (%2B) string on the request. but when we pass %2B from the get go, the CN proxy encodes those characters too?

For requests that come in with "%2B" you can see the Parameter Map has them decoded as "+":

  • Status changed from New to In Progress

Looks as though at sometime in the past it was necessary to pass to proxied services (mercury or metacat) the parameters as they were precisely on the query path.

I took that functionality out.

  • Assignee changed from Ben Leinfelder to Robert Waltz

Robert has made changes to cn proxy for this bug -- reassigning to him (I think it is resolved but would like to double check)
