Hi people, i have an functional python example code, to login an
internal network, but i not found the pascal way using the
jhttpclient, this is the python example:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i def
conection_very_data(username, password):    """    :param username:
Número de teléfono registrado en la plataforma de mi.cubacel.net   
:param password: Contraseña registrada en la plataforma de
mi.cubacel.net    :return: Interpretación de BeautifulSoup del código
fuente de la pagina de datos del perfil    """   
urllib3.disable_warnings()    r2 =
requests.get("https://mi.cubacel.net:8443/login/images/cimg/86.jpg",
verify=False,                      cookies=requests.session().cookies,
stream=True)    data = {        "language": "es_ES",       
"username": username,        "password": password,        uword":
"every"    }    r3 =
requests.post("https://mi.cubacel.net:8443/login/Login", data=data,
verify=False, cookies=r2.cookies)    r5 =
requests.get("https://mi.cubacel.net/primary/_-ijqJlSHh",
verify=False, cookies=r3.cookies)    soup = BeautifulSoup(r5.text,
"html.parser")    return soup
and this is my try implementation:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i var 
cookie:jobject;begin  cookie:=jHttpClient1.AddCookie('https://mi.cubac
el.net:8443/login/images/cimg/86.jpg','verify','false');  jHttpClient1
.GetAsync('https://mi.cubacel.net:8443/login/images/cimg/86.jpg'); 
jhttpclient1.SetCookieAttributeValue(cookie,'language','es_ES'); 
jhttpclient1.SetCookieAttributeValue(cookie,'username','user1'); 
jhttpclient1.SetCookieAttributeValue(cookie,'password','xxxx'); 
jhttpclient1.SetCookieAttributeValue(cookie,'uword','every');   
jhttpclient1.AddNameValueData('language','es_ES'); 
jhttpclient1.AddNameValueData('username','user1'); 
jhttpclient1.AddNameValueData('password','xxxx'); 
jhttpclient1.AddNameValueData('uword','every');   jhttpclient1.PostNam
eValueDataAsync('https://mi.cubacel.net:8443/login/Login','language=es
_ES&username=user1&password=xxxx&uword=every'); 
//ShowMessage(contentsum);  jhttpclient1.GetAsync('https://mi.cubacel.
net/primary/_-ijqJlSHh');end; the page not respond, any help?

Quotehe page not respond, any help?

"jHttpClient1.GetAsync" and "jhttpclient1.PostNameValueDataAsync"  are
Asynchronous!

So, you need to handle the corresponding events....

Hi jmpessoa,
Quote"jHttpClient1.GetAsync" and
"jhttpclient1.PostNameValueDataAsync"  are Asynchronous!

yes i manage that, the problem is this:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i r2 =
requests.get("https://mi.cubacel.net:8443/login/images/cimg/86.jpg",
verify=False,                      cookies=requests.session().cookies,
stream=True)    data = {        "language": "es_ES",       
"username": username,        "password": password,        uword":
"every"    }    r3 =
requests.post("https://mi.cubacel.net:8443/login/Login", data=data,
verify=False, cookies=r2.cookies)    r5 =
requests.get("https://mi.cubacel.net/primary/_-ijqJlSHh",
verify=False, cookies=r3.cookies)

r2 is a request to a captcha imagen  that save the cookies in some
where to make a post request (r3) with that cookie, context and data.

r5 is a get with the r3 cookies as parameter and with the loggin done.

the cuestion es how i do this with jhttpclient? my try responce with
"" content

But

Quoter2 = requests.get(................

Is synchronous  logic..... so, change the LAMW code to  synchronous 
methods, too.

Or refactore your code for Asynchronous logic....  [not sequential
line after line ....]

yes you are right, when you call getasync the above code have not
effect over that method because it has move to other threads i think,
i am go to make some changes and find a public webpage to logging with
jhttpclient using coockies for you can do tests

----------------------------------------------------------------------

I make some progress, this code work:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
jWebView1.Navigate('https://mi.cubacel.net/primary/_-ijqJlSHh'); 
jHttpClient1.ClearCookieStore();   cookie:=jHttpClient1.AddCookie('htt
ps://mi.cubacel.net:8443/login/images/cimg/86.jpg','verify','false'); 
 jHttpClient1.GetStateFul('https://mi.cubacel.net:8443/login/images/ci
mg/86.jpg');   jHttpClient1.AddNameValueData('language', 'es_ES'); 
jHttpClient1.AddNameValueData('username', 'xxxx'); 
jHttpClient1.AddNameValueData('password', 'xxxx'); 
jHttpClient1.AddNameValueData('uword', 'every');  ShowMessage(jHttpCli
ent1.PostStateful('https://mi.cubacel.net:8443/login/Login'));   jetda
taformat.text:=jhttpclient1.Get('https://mi.cubacel.net/primary/_-
ijqJlSHh');  /
but this is a synchrony code and the app is freezing some time, i try
to use jAsyncTask component but the app crash (i removed the toast and
the interface interaction of course), the other problem is an strange
thing, if i not open the page firt with a webview the jhttpclient
response with '' string, is a ssl problem maybe i add openssl to the
uses clause, but one problem at a time 😀, so any asynchronous solution
like this?

----------------------------------------------------------------------
jmpessoa · 2020-08-29 18:23

try change the last line to:

jetdataformat.text:=jhttpclient1.GetAsync('https://mi.cubacel.net/prim
ary/_-ijqJlSHh');

and handle the result in the event....

----------------------------------------------------------------------
Segator · 2020-08-30 01:01

Yes that solution work 👍, now the other rare problem, jhttpclient not
open an https sites, but if you open that sites first with a webview
then jhttpclient can downloaded the html, i add the openssl to the
uses but i can't use jhttpclient without webview to browse https
sites?, any suggestions or solution?.

----------------------------------------------------------------------
jmpessoa · 2020-08-30 01:24

Indeed, jhttpclient don't  have [yet] a good support to https ....
sorry.

----------------------------------------------------------------------
Segator · 2020-08-30 14:31

but we can try to improved it, i see other thread with https or ssl
problem and  the people copy a openssl arm build to the folder
library, but the system (android) have the own ssl library, must by a
way to use it with out using an external it's the ssl library the
problem?.

----------------------------------------------------------------------
jmpessoa · 2020-08-30 16:42

Quotethe people copy a openssl arm build to the folder library...

Yes, a pure Free Pascal  using "FPHttpClient.pas"  solution....

Quote but the system (android) have the own ssl library....

this is what we need!

----------------------------------------------------------------------

Finally i solve the jhttpclient ssl problem with untrusted
certificates, i add a new function to trust all certificates, use this
if you really trust in the URL for security reasons, just wait the
@jmpessoa approval in the github code and update it.

Done!

Thank you!

[Help] What about "put" and "delete"?   [so we can support RestFull
Apis....]
You can try mimic  the "get" [or "post"]  method code...

----------------------------------------------------------------------
Segator · 2021-01-17 14:26

I make some search an maybe is simple as change the method name like
client3.setRequestMethod("GET") to client3.setRequestMethod("PUT") or
DELETE, maybe is look like better a function to change this with the
same mimic as "setRequestMethod" in jhttpclient.
