delphi - Updated to Indy 130 packages from 120 and now this code does not work -

-

so used work without hitch "socket error #10054 connection reset peer."

i assume started happening once updated indy packages. today first time running code since then.

can explain how update might have changed behavior of code , how resolve it?

thank you

function postdata(url : string; param: tstringlist) : string; var   text: string;   shttpsocket: tidhttp;   sshsockethandler: tidssliohandlersocketopenssl;   resstream: tstringstream; begin   shttpsocket := tidhttp.create;   sshsockethandler := tidssliohandlersocketopenssl.create;   shttpsocket.iohandler := sshsockethandler;   shttpsocket.request.contenttype := 'application/x-www-form-urlencoded';   shttpsocket.request.method := 'post';   resstream := tstringstream.create;    shttpsocket.post(url, param, resstream);   resstream.seek(0, sofrombeginning);   text := resstream.datastring;   result := text; end;

if posting https url, make sure tidssliohandlersocketopenssl configured server trying connect to. chances are, defaults might not matching server expecting. in particular, tidssliohandlersocketopenssl.method , tidssliohandlersocketopenssl.sslversions properties default tlsv1, maybe server not support tlsv1.

on side note, tstringstream operates differently in d2009+ did in earlier versions, suggest avoid , let indy decode text you:

function postdata(const url : string; params: tstrings) : string;  var    shttpsocket: tidhttp;    sshsockethandler: tidssliohandlersocketopenssl;  begin    shttpsocket := tidhttp.create;    try     sshsockethandler := tidssliohandlersocketopenssl.create(shttpsocket);      // configure sshsockethandler needed...     // perhaps try @ minimum:     // sshsockethandler.ssloptions.method := sslvsslv23;     shttpsocket.iohandler := sshsockethandler;      result := shttpsocket.post(url, params);        shttpsocket.free;   end; end;

on website user have 1 group. , user can change group. it's made user.groups.clear() and user.groups.add(new_group) but it's not efficient, because there 2 sql query: delete, insert. how can change group update query? user , group related each other using manytomanyfield . means intersection table exists relating both entities, , if don't specify model map (using through attribute) django creates 1 you. looking @ sources django.contrib.auth.models see that's case. fortunatly, can access intermediary model using through attribute of manager (in case, user.groups.through ). can use regular model. example: >>> alice = user.objects.create_user('alice', 'alice@example.com', 'alicepw') >>> employee = group.objects.create(name='employee') >>> manager = group.objects.create(name='manager') >>> alice.groups.add(employee) >>> alice.groups.all() [<group: employee...
