RE: bug in osOpenHttpUrl()

[Ken Smith <KSmith@conita.com>]

What I've seen is that URI's that are built like this:

    <goto next=http://server/path?name=value&name=value/>

 

don't work because xerces chokes on the & itself.

 

For example, I tried the following

 

         <form id="menu"> 

         <block><goto next="http://bubble/vxml/test16.vxml?lang=fr&tech=machin"/></block>

         </form>

 

While stepping through the execution with the debugger, I see the following call sequence:

 VXI::block_element()  calls into VXI::execute_content(),  which then fails to see the <goto> element at all.  If I remove the '&tech=machin' option, it

works fine, execute_content() finds the <goto> element. 

I tried to build the URI with an expression like  "'http://bubble/vxml/test16.vxml' + '?lang=fr' + '&tech=machin'" and it failed too. 

I then replaced the & with a ; and it worked ok.  Looks like the & is causing some internal distress.

My patch was for the <grammar> tag and not the <goto> tag.  

OK ... i was believing you wanted to patch all http connexion ... sorry

Is there any reason to have an anchor '#' in a grammar tag?

no ;-))

As for the goto, the following worked (the gotest.jsp had two forms, one named moose and one named bad)
<goto next="gototest.jsp?dog=snoopy#moose/>  <- went to moose
and
<goto next="gototest.jsp#moose/> <- went to moose
and
<goto next="gototest.jsp?dog=snoopy/> <- went to bad (which was correct)
 
what didn't work was
<goto next="gototest.jsp?dog=snoopy&cat=kitty#moose/> 

i'm agree with you...
but for 1 , can you got dog variable or openVXI translate  gototest.jsp?dog=snoopy#moose in gototest.jsp#moose?

any suggestions?

No ... if it's working for goto or submit with you patch, then it's good... you add a functionnality...

have you try submit?

Yes, it's true it don't work for goto tag...

i try this

<goto next="http://bubble/vxml/test16.vxml?lang=fr"/>

i get bad fetch (it's normal) but in my appache access log, i get http://bubble/vxml/test16.vxml and not http://bubble/vxml/test16.vxml?lang=fr

i try this:

<goto next="http://bubble/vxml/test16.vxml#lang"/>

idem than http://bubble/vxml/test16.vxml?lang=fr

i try this

<goto next="http://bubble/vxml/test16.vxml?lang=fr&truc=machin"/>

i got an error: VXI abort and return NULL

--> thus there is an error with &

i try this

<goto expr="'http://bubble/vxml/test16.vxml' + '?lang=fr' + '&truc=machin'"/>

and i got the same problem ;-))

Well it was a lot easier to fix then I thought:

i'm going to try you patch ... but (see further in the code...)

There are two parts to the fix

Part I (one change).  Concatenate the "extra information" to the end of the

querystring

  queryStringStr[0] = 0;

  addQueryStringToUrl( queryStringStr, URL_EXTRA_LENGTH, queryObj );

  printf("queryStringStr = %s\n",queryStringStr);

becomes

  queryStringStr[0] = 0;

  addQueryStringToUrl( queryStringStr, URL_EXTRA_LENGTH, queryObj );

  // change 1 or 1 -  this might not be totally correct.  Does not work

  // with anchors (i.e. grammar.jsp#dog), but why would you have these?

because anchors are important in link and goto tag ...

in voiceXML 1.0, you have to use anchors to go to a specified dialog in other document (or in the same document...)

like this:

<goto expr="(type==true) ? 'utilities.vxml#confirm' : 'utilities.vxml#bye' />

Is somebody has a solution to manage ? (and & ) and also  anchors # ???

thank you

  if (VXIstrlen(comp->lpszExtraInfo)>0 && comp->lpszExtraInfo[0]=='?')

  {

        if(VXIstrlen(queryStringStr)>0) // if not first, put in '&'

          VXIstrcat(queryStringStr,"&");

        VXIstrcat(queryStringStr,comp->lpszExtraInfo+1); // skip the '?'

  }

  printf("queryStringStr = %s\n",queryStringStr);

Part II (two changes). Use the extra data (there might NOT be a queryObj

even though there is "extra information")

  if(fetchMethod && (VXIstrcmp(fetchMethod, URL_METHOD_POST) == 0)){

    strcpy(path,comp->lpszUrlPath);

    if(queryObj)

      extra_data = queryStringStr;

    cacheFlag = URL_DO_NOT_CACHE;

  }

  else{

    if(cacheFlag == URL_DO_NOT_CACHE)

      cacheFlag = URL_DO_NOT_CACHE;

    strcpy(path,comp->lpszUrlPath);

    if(queryObj && (VXIstrlen(queryStringStr) > 0)){

      strcat(path,"?");

      strcat(path, queryStringStr);

    }

  }

becomes:

  if(fetchMethod && (VXIstrcmp(fetchMethod, URL_METHOD_POST) == 0)){

    strcpy(path,comp->lpszUrlPath);

    // CHANGE 1 OF 2

    //if(queryObj)

      extra_data = queryStringStr;

    cacheFlag = URL_DO_NOT_CACHE;

  }

  else{

    if(cacheFlag == URL_DO_NOT_CACHE)

      cacheFlag = URL_DO_NOT_CACHE;

    strcpy(path,comp->lpszUrlPath);

    // CHANGE 2 OF 2

    if(/*queryObj && */(VXIstrlen(queryStringStr) > 0)){

      strcat(path,"?");

      strcat(path, queryStringStr);

    }

  }

Subject: bug in osOpenHttpUrl()

osOpenHttpUrl() ignores the "extra" information that is in the url.

extra, as defined by microsoft's InternetCrackURL is

"extra information (for example, ?something or #something)"

so if I have a grammar

<grammar src="http://yahoo.com?spanish=t"/>  I only get <grammar

src="http://yahoo.com"/>

Anyone have a fix for this before I go and do it myself?
