Android Question Simple API Request with key and certificate

[CorryWestSide]

hi i have this code in php that i wrote some month ago, my question is, can i write this in b4a?
the actual difficoult that i encounter is given by the file .crt and .key for the ssl. Someone can help me in some way?

function post_listaDispositivi() {
    $body = trim(file_get_contents('php://input'));
    
    $crt_path = "./Chiavi/" . $body . "/" . $body . ".crt";
    $key_path = "./Chiavi/" . $body . "/" . $body . ".key";
    
    //$crt_path = "./Chiavi/" . $body . "/" . $body . ".crt";
    //$key_path = "./Chiavi/" . $body . "/" . $body . ".key";
    
    if( !file_exists($crt_path) || !file_exists($key_path) ){
        echo "-1";
        return "-1";
    }
    
    $url = "https://apig-ivaservizi.agenziaentrate.gov.it/apig/v1/gestori/me/dispositivi/?perPage=500000";
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_PORT , 443);
    curl_setopt($ch, CURLOPT_VERBOSE, 1);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    
    curl_setopt($ch, CURLOPT_SSLCERT, $crt_path);
    curl_setopt(curl, CURLOPT_SSLCERTTYPE, "CRT");
    curl_setopt($ch, CURLOPT_SSLKEY, $key_path);
    
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
                
    if( strtoupper($method) == "POST" )
    {
       curl_setopt($ch, CURLOPT_POST, 1);
       curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
    }

    $response = curl_exec($ch);
    $info =curl_errno($ch)>0 ? array("curl_error_".curl_errno($ch)=>curl_error($ch)) : curl_getinfo($ch);
    print_r($response);
    curl_close($ch);
    return $response;
}

For server app, use B4J. Not B4A.

yeah i know....but the problem is that i need it in b4a...for this reason im looking for help

If I understand correctly, there are 2 parts.
1. You need to receive request (http POST) from a client. If you want this run on Android device, you need to check for httpserver using B4A.
2. It seems the app need to make a http request to another server. On this part, it could be done using OkHttpUtils2.

Maybe you don't need a http server on Android if you can specify the value of the body i.e the name of the certificate which is just a string in B4A.

I maybe wrong. I read that Okhttp does not support client certificate. Not sure if it is still true.

okay so, Actually the php code that i post stand on a site and with my b4a app i make an api request to my siteand the php run the other api request.

so i have
App -> Site -> Destination

but i wanna only use
App -> Destination

Actually in the code

Dim j As HttpJob
    j.Initialize("", Me)
    j.PostString("https://www.sisoftsrl.it/wp-admin/admin-post.php?action=listaDispositivi", Comodo.UserCode)
    Wait For (j) JobDone(j As HttpJob)
    If j.Success Then
        response = j.GetString
        valorizzaUid(idDispositivo)

i use this "solution" with site just because in b4a i dont know how to pass .crt and .key file for openssl to give for api call
because the Destination wanna this certificate for give me the access to data

pass your certs (in pem format) as headers
