Hello, I try to reproduce this kind of python code into haskell --- python -- whcih use the suds module cj = CookieJar() url_opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj)) transport = HttpAuthenticated(username=self.getIspybUserName(), password=self.getIspybPassWord()) service_name = "ToolsForCollectionWebService" url = "http://195.221.10.20/ispyb-ws/ispybWS/ToolsForCollectionWebService?wsdl" collectionWSClient = Client(url, transport=transport, timeout=3) collect_params = collectionWSClient.service.findDataCollection(dataCollectionId)--- --- Has you can see, I create a Transport whcih need an Authentification and also I need to use a cookieJar in oder to manage the connection. The a soap client is instanciated from the url and with this transport. Then the findDatacollection service is called. Now I would like to reproduce this with Haskell and the soap package (or not if it is easier without) I started like this getDataCollection :: Transport -> Int -> IO Response getDataCollection t i = invokeWS t url () body parser where url = "http://195.221.10.20/ispyb-ws/ispybWS/ToolsForCollectionWebService?wsdl" -- ?wsdl/findDatacollection" body = elementA "ToolsForCollectionWebService" [("xmlns", "findDataCollection")] $ element "dataCollectionID" i parser = StreamParser . flaxTag "" $ response response = Response <$> flaxContent "filePath" main :: IO () main = do -- Initial one-time preparations. transport <- initTransportWithM defaultManagerSettings url pure pure response <- getDataCollection transport dataCollectionID print response And When I run this I have this message autoprocessing-exe: HttpExceptionRequest Request { host = "xxx.xxx.xxx.xxx" port = 80 secure = False requestHeaders = [("Content-Type","text/xml; charset=utf-8"),("SOAPAction","http://195.221.10.20/ispyb-ws/ispybWS/ToolsForCollectionWebService?wsdl")] path = "/ispyb-ws/ispybWS/ToolsForCollectionWebService" queryString = "" method = "POST" proxy = Nothing rawBody = False redirectCount = 10 responseTimeout = ResponseTimeoutMicro 15000000 requestVersion = HTTP/1.1 } TlsNotSupported I know that I do not want the https, the url is http and not https. now I do not know how to modify this in order to deal with the authentification and the cookiesJar. It seems here that proxy is Nothing so I hope thqht it will use the http[s]_proxy environment variable. thanks for your help. Frederic
