HttpClient
« on: September 30, 2022, 01:11:16 pm »
Hellow Everybody,

I need to use a HttpClient resource to get a simple text file content from a server to the android app. I tried jHttpClient component, but nothing is returned.  I tried the fphttpclient lib but it freezes. The code with fphttpclient is very simple as show below:

URL:='http:// ....'
StrList: TStringList

with TFPHttpClient.Create(nil) do
begin
   StrList:=TStringList.Create;
   Get(URL, StrList)
   .
   .
   .
end;

The same code works well with standard Lazarus running in Debian Linux but in  Android with LAMW freezes after Get(URL) command. Any sugestion?

The LAMW Apps appears to be not connected to the Internet in the smartphone. AndroideManifest was checked and its ok. I don't understending what is happening with the App connection.

Always check logcat, Android logs even native calls.

There is no problem with Internet connection in android. The function jHttpClient is really not working.  In contrast, httpsend from synapse package is working for a http request, but https not. This is my problem now.

HttpGET: THTTPSend;
URL:='https://www ......';

My simple code is:
  HttpGET:=THTTPSend.Create;
  HttpGET.Sock.CreateWithSSL(TSSLOpenSSL);
  HttpGET.Sock.SetTimeout(5);
  HttpGET.Sock.SSLDoConnect;
  teste:=HttpGET.HTTPMethod('GET', URL);

Once again, the same code works well in Linux. In android, a https request is returning nothing. Is there some thing related with android and Linux openssl lib?

The library version might matter. OpenSSL has many "living" versions: 3.0, 1.1.X and at some rare occasions, 1.0.X. Perhaps get the raw SSL handshake result. But before that, does it return any HTTP status?

Better walking arround with jfhttpclient, if you want a challenge, this could be a hard challenge, make fpc httpclient live inside android  :D, rancak bana nian if it could happen! On previous thread i already make almost the same thread like this. Talking httpclient with null result on any methods, literally.

Jhttpclient working very well, i use it almost in all of my internet related projects.
