Hello,
I need help, folks.
I have been creating a MetaCard stack that submits to a server-side PHP program. The payload of the post cmd is of type "text/xml" and, specifically, it is the XML that an XML-RPC program expects.
The above submit works fine, and the server-side program returns what it is supposed to, b-u-t ... and here's the problem ... when the content is lengthy, my client-side stack does NOT wait long enough for the whole reply, and breaks-off the HTTP connection too soon.
What do I need to do to make my MC client WAIT for the server-side program to complete the transmission of its reply? Should I be using the urlStatus function?
I use this kind of "POST" method handler without problem all the time to access server-sided Rev or MC apps trough Apache and a PHP sockets listener/port translator. The first below line is important :
set httpheaders to "Content-type: application/x-www-form-urlencoded" & return
Try to see if you can pick somthing usable from the example code below...
on adddatas
if (fld "citation" of card 1 of stack "ccitalis" is not "*" \
and fld "citation" of card 1 of stack "ccitalis" is not "" \
and fld "citation" of card 1 of stack "ccitalis" is not "Saisir ici la nouvelle citation..." \
and fld "citation" of card 1 of stack "ccitalis" is not "Saisir ici les extraits de citation (mots-clés et/ou expressions littérales - utiliser" && quote & "+" & quote && "comme item de concaténation) entrant dans la sélection de recherche...") \
and (fld "auteur__" of card 1 of stack "ccitalis" is not "*" \
and fld "auteur__" of card 1 of stack "ccitalis" is not "" \
and fld "auteur__" is not "Saisir ici le nom de l'auteur..." \
and fld "auteur__" of card 1 of stack "ccitalis" is not "Saisir ici les noms d'auteurs (utiliser" && quote & "+" & quote && "comme item de concaténation) entrant dans la sélection de recherche...") \
and (fld "concept_" of card 1 of stack "ccitalis" is not "*" \
and fld "concept_" of card 1 of stack "ccitalis" is not "" \
and fld "concept_" of card 1 of stack "ccitalis" is not "Saisir ici le concept de référence..." \
and fld "concept_" of card 1 of stack "ccitalis" is not "Saisir ici le concept entrant dans la sélection de recherche...") then
put "ci001=FE8&END=" into retour
set httpheaders to "Content-type: application/x-www-form-urlencoded" & return
post retour to url (fld "csrecents" of cd 2 of stack "ccitalis")
if it is "" then
answer "La connexion avec le serveur distant est rompue." & return & return & \
"Vérifiez votre configuration d'accès à l'internet"
exit adddatas
end if
if lineoffset(word 1 to -1 of fld "slogin" of cd 2 of stack "ccitalis" & "¶" & word 1 to -1 of fld "smdp" of cd 2 of stack "ccitalis" & "¶",macoscharset(it)) is not "0" then
put "|TI1=" & fld "citation" & \
"|TI2=" & fld "auteur__" & \
"|TI3=" & fld "titre___" & \
"|TI4=" & fld "date____" & \
"|TI5=" & fld "concept_" & \
"|TI6=" & fld "comment_" & \
"|IDC=" & encef(word 1 to -1 of fld "slogin" of cd 2 of stack "ccitalis") & \
"|VAL=" & encef(word 1 to -1 of fld "smdp" of cd 2 of stack "ccitalis") into larequete
put isocharset(larequete) into larequete
replace "&" with "¶" in larequete
replace "|" with "&" in larequete
put "ci001=FN1" & urlencode(larequete) & "&END=" into retour
set httpheaders to "Content-type: application/x-www-form-urlencoded" & return
post retour to url (fld "csrecents" of cd 2 of stack "ccitalis")
if it is "" then
answer "La connexion avec le serveur distant est rompue." & return & return & \
"Vérifiez votre configuration d'accès à l'internet" & return & "avant de poursuivre." & return & return & \
"(succès des tests de 0% en 0 secondes)"
exit adddatas
else answer it
else answer "Vous devez vous authentifier comme utilisateur" & return & "habilité à la saisie avant de pouvoir proposer de nouvelles citations !"
else answer "Saisissez, au minimum, une citation un auteur et un concept, SVP !"
end adddatas
If the server side of your app is a MC/Rev Stack or Script, it's important to add the below line of code to the "on preopenstack" or "on startup" handlers :
set the socketTimeoutInterval to "10"
Such kind of requests runs without troubble. In about testing the limits of the method (MC/Rev client app, Apache + PHP + MC app server + PostgreSQL back-end), it's able to let the client receive up to 16 Mo of datas peer query trough a 10 Mbits LAN...
Hope this will help,
Kind Regards, Pierre
....
Btw, this XMLRPC stack will be shared with the community and will, therefore, help a *LOT* of people; notably the Rev and Pan wikis, not to mention a school commission, a network of consultants, the lab I work for, etc.
So please help me if you can,
Alain F
