Hi, I found some problems on Zinc implementation. Take this example: HTTPSocket httpGetDocument: 'http://127.0.0.1:333/analytics/feeds/accounts/default' args: (Dictionary new at: 'prettyprint' put: #('true'); yourself) accept: '*/*' request: ('Authorization: GoogleLogin Auth={1}{2}' format: {self authenticationKey. String crlf} this, if I have the correct authentication key, gives me the correct answer (an atom-xml response). Now, if I try: ZnHTTPSocketFacade httpGetDocument: 'http://127.0.0.1:333/analytics/feeds/accounts/default' args: (Dictionary new at: 'prettyprint' put: #('true'); yourself) accept: '*/*' request: ('Authorization: GoogleLogin Auth={1}{2}' format: {self authenticationKey. String crlf} (this should work, as the facade is for compatibility, I think) I have two errors, one of them easily solvable, and the other... well... I couldn't solve it in the 15' I spent on it :) 1) arguments are not in the correct way. While HTTPSocket functions expect something like this: Dictionary new at: 'prettyprint' put: #('true'); "<-- Parameter is an array" yourself. ZnHTTPSocketFacade expects something like this: Dictionary new at: 'prettyprint' put: 'true'; "<-- Parameter is a string" yourself. 2) This is the hard one. If you do the get request with parameter fixed, you should get the atom feed. But you don't. You get a ZnResponse who is OK (status 200), but entity is empty. I followed the error until this method: canReadContent ^ self hasContentLength or: [ self isChunked or: [ self allowsReadingUpToEnd ] ] who return false, because none of the questions is true. Then, no entity is filled, and I have no answer :( Hope this help :) Cheers, Esteban
