Http Post data slow in WB

[Jeremy Whilde]

I have been testing a way to post http data to a web host but need fast performance
so this is what I did using VBS.

Dim xmlhttp

Set xmlhttp = CreateObject("MSXML2.ServerXMLHTTP")

' Page that will receive Post
xmlhttp.Open "POST", "http://posttestserver.com/post.php", False

' Indicate that the body of the request contains form data
xmlhttp.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"

' Send the data as name/value pairs
xmlhttp.send "Data=test123&more data=456"

' read response body
WScript.Echo xmlhttp.ResponseText

Set xmlhttp = Nothing

Then tried the following in WB

;--------------------------
; UrlEncoded POST form data
;--------------------------

AddExtender("WWINT44I.DLL")
tophandle=iBegin(0,"","")

connecthandle=iHostConnect(tophandle, "posttestserver.com", @HTTP, "", "")

; REQUEST_URI
url1="/post.php"

; Initialise data handle and setup for Http request
datahandle=iHttpInit(connecthandle,"POST",url1,"", 7)
if datahandle==0
   err=iGetLastError()
   Message("Last Error",err)
   iClose(tophandle)
   exit
endif

; Format variable data into encoded URL for POST
urldata=""                             ;initalise url data variable
urldata=iContentUrl(urldata,"data","test123")   ; 1st key data here
urldata=iContentUrl(urldata,"more data","456")   ; 2nd key data etc.

; Actually send the Http data to the host
rslt = iHttpOpen(datahandle, "", urldata, -1);

if rslt=="ERROR" || rslt!=200
   if rslt == "ERROR"
       errstr = "WinInet Error"
       rslt = iGetLastError()
   else
       errstr = "HTTP Error"
   endif
   
   Message(errstr,rslt)
   iClose(tophandle)
   exit
endif

; Check the response from the Http POST
xx=iReadData(datahandle,"test.html")
iClose(datahandle)
iClose(connecthandle)
iClose(tophandle)

; Display response in Notepad
Run("Notepad.exe","test.html")

exit

; Display response in a browser
Origin = DirGet()
test = StrCat(Origin,"test.html")
Run(test,"")
exit

Both VBS & WB methods work but the WB script is considerably slower, is there a better way (faster) in WB to do this?

Thanks JW

You could try converting the VBS directly to WB. Should run about the same.

Yes that did occur to me after I had posted the examples, maybe I'll give it a go. Was also thinking of maybe running a cURL from WB but that would involve another dependency I guess. Was wondering if anyone else had any slick ways to do this.

Here is the vb equivalent WinBatch code:

Code (winbatch) Select Expand

xmlhttp = CreateObject("MSXML2.ServerXMLHTTP")

;Page that will receive Post
xmlhttp.Open("POST", "http://posttestserver.com/post.php", @False)

; Indicate that the body of the request contains form data
xmlhttp.setRequestHeader( "Content-Type", "application/x-www-form-urlencoded")

; Send the data as name/value pairs
xmlhttp.send("Data=test123&more data=456")

; read response body
Pause('ResponseText', xmlhttp.ResponseText)

xmlhttp = 0
exit

 I tested the WinInet code. it seemed quick for me. However I modified the code to use a binary buffer instead of writing out to a file to attempt to speed it up. Here it is:

Code (winbatch) Select Expand


;--------------------------
; UrlEncoded POST form data
;--------------------------

AddExtender("WWINT44I.DLL")
tophandle=iBegin(0,"","")

connecthandle=iHostConnect(tophandle, "posttestserver.com", @HTTP, "", "")

; REQUEST_URI
url1="/post.php"

; Initialise data handle and setup for Http request
datahandle=iHttpInit(connecthandle,"POST",url1,"", 7)
if datahandle==0
   err=iGetLastError()
   Message("Last Error",err)
   iClose(tophandle)
   exit
endif

; Format variable data into encoded URL for POST
urldata=""                             ;initalise url data variable
urldata=iContentUrl(urldata,"data","test123")   ; 1st key data here
urldata=iContentUrl(urldata,"more data","456")   ; 2nd key data etc.

; Actually send the Http data to the host
rslt = iHttpOpen(datahandle, "", urldata, -1);

if rslt=="ERROR" || rslt!=200
   if rslt == "ERROR"
       errstr = "WinInet Error"
       rslt = iGetLastError()
   else
       errstr = "HTTP Error"
   endif
   
   Message(errstr,rslt)
   iClose(tophandle)
   exit
endif

; Check the response from the Http POST
size=10000
buf=BinaryAlloc(size)
;Get address of buffer
bufaddr=IntControl (42, buf, 0, 0, 0)
BinaryEodSet(buf, size)
iReadDataBuf( datahandle, bufaddr, size )
ResponseText = BinaryPeekStr(buf, 0, BinaryEodGet( buf )) 
Pause( "ResponseText", ResponseText )
BinaryFree( buf )
iClose(datahandle)
iClose(connecthandle)
iClose(tophandle)
exit

Thanks will try both out tomorrow.

Thanks JW

OK yes both the MSXML2 & the WinInet  with the binary buffer work I still think the MSXML2 is a little faster also tried WinHttpRequest COM object which is also a similar speed.

; Instantiate a WinHttpRequest object.
oWinHttp= CreateObject("WinHttp.WinHttpRequest.5.1")

; Initialize an HTTP request. 
oWinHttp.Open("POST", "http://posttestserver.com/post.php", @false)

; Post data to the HTTP server.
oWinHttp.Send("Data=test123&more data=456")

; read response body
Pause('ResponseText', oWinHttp.ResponseText)

Thanks JW
