cfhttp + post + multipart problem

[vovasvv]

Hi, I’m trying to make cfhttp request with post method and multipart=”yes” attrib (trying to emulate form submiting). I use CF8 build 8.01, Wireshark, FF 3.6.16.

The problem is that I get Status code: 500 Internal Server Error in response

My cf code:

<cfscript>

request.strRAtr = {

    method="post",

      url="….",

      useragent="Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2.15) Gecko/20110303 Firefox/3.6.15 (.NET CLR 3.5.30729)",

      redirect="no",

      multipart = "yes";

      result = "variables.strReqRes"     

};

request.arrRParam = [

      {     type = "header",

                        name="Host",

                        value="…"

                    },

      {     type = "header",

                        name="Accept",

                        value="text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"      

      },

      {     type = "header",

                        name="Accept-Language",

                        value="en-us,en;q=0.5"       

      },

      {     type = "header",

                        name="Accept-Encoding",

                        value="gzip,deflate"

      },

      {     type = "header",

                        name="Accept-Charset",

                        value="ISO-8859-1,utf-8;q=0.7,*;q=0.7"

      },

      {     type = "header",

                        name="Keep-Alive",

                        value="115"

      },

      {     type = "header",

                        name="Connection",

                        value="keep-alive"

      },

{     type = "header",

                        name="Referer",

           value="…."

            }

];

request.strCookieParam = {

      type="cgi",

      name="Cookie",

      value="……",

      encoded="no"           

};         

</cfscript>

<cfhttp attributecollection="#request.strRAtr#">

            <cfloop from="1" to="#arrayLen(request.arrRParam)#" index="i">

<cfhttpparam      type = "#request.arrRParam.type#"

                  name = "#request.arrRParam.name#"

                              value = "#request.arrRParam.value#">

            </cfloop>

<cfhttpparam      type = "formfield"

                  name = "wizardMode"

                  value = "…">

<cfhttpparam attributecollection="#request.strCookieParam#">

</cfhttp>

I’ve analysed the Wireshark – the difference between cfrequest and request from FF is in <mime_multipart chunk> (I export captured data from Wireshark into PDML – xml packet detail)

From FF I’ve get:

<proto name="mime_multipart" showname="MIME Multipart Media Encapsulation, Type: multipart/form-data, Boundary: &quot;---------------------------311112870412835&quot;" size="4585" pos="936">

        <field name="data.len" showname="Length: 4" size="0" pos="1035" show="4"/>

          </field>

And from CFHTTP:

      </proto>

    </field>

As you can see, CFHTTP creates «Encapsulated multipart part:  (text/plain)» and «data-text-lines» – why??? I suppose, that this difference is explanation of Status code: 500 Internal Server Error in response. Am I right? And what I have to do for right post in that case?

Thanks.

So, my question - my answer. First of all,  my supposition about "...I suppose, that this difference is explanation of Status code: 500 Internal Server Error in response..." was WRONG!

For all people, who want to uderstand post_multipart I recomend to read RFC1341 (http://www.w3.org/Protocols/rfc1341/7_2_Multipart.html)

My problem was on another side:

I post "wrong" example in this thread -  in cfhttp I rote "...

<cfhttpparam      type = "formfield"

                  name = "wizardMode"

                  value = "…">...

"

But actualy value was "-1". In CFML Reference on p.290 I found that: "...All
form field data must be encoded in this character encoding, and ColdFusion does not
URLEncode the data..."!!!!!

That's IT !!!!!

I forgot about URLEncodedFormat function - and this was my actual problem!!!
