Hello at all

Thanks to INFRATEC and several members of this forum, i believe i have a little bit understand how use CURL

I have try to send a GET request without success, CURL not see the parameter send

For ask at PB forum to search "KCC", i want send that :

http://www.purebasic.fr/english/search. ... mit=Search

But the result is the full search panel of PB, not the list of thread of KCC

If someone see where is the problem

It works for me.
I am not using proxy$

Code: Select all

 Proxy$ = "";  "http://xxxxxx.xxx.fr:3128"

kcc if you don't mind adding one extra file to your program I think you should give "phantomjs" a try.
it will do all that you want to do. The only problem is that you will need to learn JavaScript but for all the stuff you want to do on the web, if you want to make your job easier; then you need to learn some JavaScript.

phanthomjs has compiled binaries ready to be used. I downloaded the windows version to my "G:" drive if you download it make sure you change the directories. I haven't tried the proxy setup but it should be pretty easy to understand and I added the switch there so you can see how the command should look.

Code: Select all

;phantom JS "post.js" file in the examples folder
; use it to post data to a website

; // Example using HTTP POST operation
; 
; "use strict";
; var page = require('webpage').create(),
;     server = 'http://posttestserver.com/post.php?dump',
;     Data = 'universe=expanding&answer=42';
; 
; page.open(server, 'post', Data, function (status) {
;     If (status !== 'success') {
;         console.log('Unable to post!');
;     } Else {
;         console.log(page.content);
;     }
;     phantom.exit();
; });


 pjs = RunProgram("G:/phantomjs-2.1.1-windows/bin/phantomjs.exe","--proxy=xxxxxx.xxx.fr:3128 --ignore-ssl-errors=true G:\phantomjs-2.1.1-windows\examples\post.js -v ","",#PB_Program_Hide|#PB_Program_Open| #PB_Program_Read| #PB_Program_Write)
output$ = ""
line$ = ""
If pjs
  While ProgramRunning(pjs)
    If AvailableProgramOutput(pjs)
      line$ = ReadProgramString(pjs) + Chr(13)
      Debug line$
      output$ + line$
    EndIf
  Wend
  output$ + " Exitcode: "+Str(ProgramExitCode(pjs))
  CloseProgram(pjs)
EndIf

Hello Normeus

That work for you !!!!

Decidedly, i not understand, perhaps again a proxy problem. ..

PhantomJS yes it's also a good idea.
I have try it they are a long time, and i have not continue with it, because it not works on XP

I have again some machine under XP...

I have also thinking to selenium, with python.
Thanks to Infratec it's possible to use python with pb, it's also another solution. ..

So i keep your code preciously, we never know

Thanks a lot for your help and advice
Have a good night

@INFRATEC
Waoouuuh !!!! You have found the problem ?
Again a time, i'm on android. ..

Tommorow at the first time, i test it .
You are really an angel.
Im really a wound for you

Have a very good night too, mainly without kcc in your nightmare

Hi,

I changed my last code.
Now the result is shown in a webgadget and I added a POST example.
For that you have to change your username and password.

Hello INFRATEC

You are a mother for me

Never you imagine how this code can change my life.
After the 10 years of COM, 2 years of TELNET, this time, thanks to you, perhaps i can talking directly at the hears of the server

Without passing by a navigator...i dream awake.

Sure i talk the server language, also good that english...then surely they are some misunderstood between him and me

But have found his hear thanks to you, it's already a big step in the history of human KCC

I can test your splendid code in few minutes when i'm finally behind a pc, and i'm so much impatient. ..

I give to you some news...

Posted: **Thu Nov 24, 2016 10:44 am**

It's super that works better !!!

When i run your code i always a MsgBox "Script error, do you want to continue ?", i don't know why

Url : about:./mobiquo/tapatalkdetect.js

When i click yes, i'm connected to the forum

Just a little strange thing, after several seconds, the webgadget return alone to the panel of login

http://www.purebasic.fr/english/ucp.php?mode=login
Surely a security somewhere ???

And when i test my old request

Code: Select all

*Buffer = RequetteHTTP("http://www.purebasic.fr/english/search.php", "keywords=kcc&terms=all&author=&sc=1&sf=all&sk=t&sd=d&sr=topics&st=0&ch=300&t=0&submit=Search", #Requette_GET, Proxy$, #False,10)

All are done

In fact, again thanks to you, i have understand something other
When i connect for the first time of the day, it's not the same PROXY of all the day
And after, i can take the second, and always use it, the first not work, and never work in all the day
It's for this reason, all the code i test not working for me

It's strange like behaviour no ?

And like say DJES, i can't send the Login/Pass directly to the PROXY
I'm forced to enter it in a inputrequester, who appears automaticaly when i connect to internet
And only after i can cross the proxy, only if i send again Login/Pass at each request in your code
Surely a double protection....

So you are really too strong, i love you
Long life to you, and the germany

So ...this is the result of France and french people
For GERMANY.....twelve points

Have the best day of the world
