| User883 Posts: 1 Member Since: 03/01/01 |
posted March 1, 2001 10:02 AM I'm using the DartWeb.Http object, and am having a problem posting an xml request to my xml portal. I noticed that when I use the same request with the microsoft XMLHTTP object the byte count is one less than when I Post the same request with your object. I'm not sure, but it looks like that's the only difference, and their object works, and yours doesn't. I've used your tools for other HTTP requests, and have never had a problem, and am trying to convince our clients to use your tool, but I won't be able to if I can't get it to work on my XML portal. Here's a quick sample: Set ReqHeaders = createobject("dart.dartstrings") Set RespHeaders = createobject("dart.dartstrings") sRequest = "<?xml version = ""1.0""?> <!DOCTYPE REQUEST SYSTEM ""http://www.localhost.com/XMLPortal/xml.dtd"">" & _ "<REQUEST version=""1.0"">" & _ "</REQUEST>" ReqHeaders.Delimiter = vbCrLf reqHeaders.add "Connection: Keep-Alive" & vbcrlf & _ "Content-Type: text/xml" lsURL = "http://www.localhost.com/XMLPortal/XML.asp" Set objWinSock = createobject("Dart.Http") objWinSock.Url = lsURL sResponse = "" objWinSock.Post sRequest, ReqHeaders, sResponse, RespHeaders msgbox(RespHeaders.all & vbcrlf & sResponse) set HttpObj = createObject ("Microsoft.XMLHTTP") HttpObj.open "POST", lsURL, false HttpObj.setRequestHeader "Content-type", "text/xml" HttpObj.send sRequest msgbox(HttpObj.responseText) Can you tell me why there's a difference in the byte count for Content-Length? I think it might be causing a problem with the Microsoft.FreeThreadedXMLDOM object I'm using. Thanks for your help -Mike |

posted March 1, 2001 10:33 AM The byte count should be the length of sRequest. Is that the case? Thanks, Tony Priest Dart Tech Support |

posted March 28, 2001 1:02 PM Sorry for the delay, I was waiting for an e-mail reply (my fault! ;-) --- Anyhow, Here's an example where the length of sRequest is 14 and the web page gets a content header value of 15! Set ReqHeaders = createobject("dart.dartstrings") Set RespHeaders = createobject("dart.dartstrings") sRequest = "THIS_IS_A_TEST" ReqHeaders.Delimiter = vbCrLf Set objWinSock = createobject("Dart.Http") objWinSock.Url = "http://localhost/darttest.asp" ' darttest.asp = <%Response.write (Request.ServerVariables("ALL_RAW")%> sResponse = "" msgbox(len(sRequest)) objWinSock.Post sRequest, ReqHeaders, sResponse, RespHeaders msgbox(RespHeaders.all & vbcrlf & sResponse) I'm using NT Workstation running service pack 6a and PWS (but the same thing happens on our production IIS4.0 machine). I'm currently using a workaround where my clients are posting data as www-url-form-encoded, but if there was a problem there as well, if they didn't add chr(0) to the end of the data stream that they sent, sometimes we'd get a random character on the server side... (I think in part becuase the content-length that IIS Recieves is wrong...) Thanks for your help (and I'll check the board later for a response! ;-) |

posted March 28, 2001 1:18 PM The server sends out the web page. The server adds the Content-Length line. I'm not sure what we are supposed to do about that. Tony |

posted March 28, 2001 4:14 PM Are you sure about that? I created a small application that simply listens on port 80, and this is the POST that came from that code I posted in my earlier message: POST /darttest.asp HTTP/1.1 Accept: */* Content-Type: application/x-www-form-urlencoded Content-Length: 15 User-Agent: Dart Communications PowerTCP Host: localhost Connection: Keep-Alive THIS_IS_A_TEST To put it another way, if I use the MS XMLHTTP object, the content-length shows up as 14: set xmlhttp = CreateObject("Microsoft.XMLHTTP") xmlhttp.Open "POST", "http://localhost/darttest.asp", false xmlhttp.Send sRequest msgBox xmlhttp.ResponseText In this case response shows me a correct content-length of 14 Thanks, Mike |

posted March 28, 2001 4:44 PM Using the shipping DLL and the following code: Option Explicit Private Sub Command1_Click() On Error GoTo OnError Command1.Enabled = False Http1.Url = "http://localhost:8080/darttest" Http1.Post "THIS_IS_A_TEST" GoTo Done OnError: Debug.Print "ERROR #" + CStr(Err.Number) + ": " + Err.Description Done: Command1.Enabled = True End Sub I received this: POST /darttest HTTP/1.1 Accept: */* Content-Type: application/x-www-form-urlencoded Content-Length: 14 User-Agent: Dart Communications PowerTCP Host: localhost:8080 Connection: Keep-Alive THIS_IS_A_TEST It seems OK to me.

posted March 29, 2001 7:50 AM Great! Can you tell me where I can get this "Shipping Dll" or confirm that I have the right version? It has been a while since I downloaded the software. My DartSock.dll is version: 2.0.37.9 and DartWeb.dll is: 1.0.37.0 Thanks, Mike |

posted March 29, 2001 8:17 AM OK, it looks like the current version on your web site is 1.0.43. Will my current license work for that version? Thanks, Mike |
