Bitcoin RPC is working on UBUNTU but not on Windows.

I am using exactly the same library.

My php code :

<?php
require_once('../Easy_btc/easybitcoin.php');
$bitcoin = new Bitcoin("rpcuser","rpcpassword","localhost","80");
$b = $bitcoin->getinfo();
var_dump($b);
var_dump($bitcoin);
?>

The error I get :

object(Bitcoin)#1 (12) {
  ["username":"Bitcoin":private]=>
  string(7) "rpcuser"
  ["password":"Bitcoin":private]=>
  string(11) "rpcpassword"
  ["proto":"Bitcoin":private]=>
  string(4) "http"
  ["host":"Bitcoin":private]=>
  string(9) "localhost"
  ["port":"Bitcoin":private]=>
  string(2) "80"
  ["url":"Bitcoin":private]=>
  NULL
  ["CACertificate":"Bitcoin":private]=>
  NULL
  ["status"]=>
  int(0)
  ["error"]=>
  string(23) "Empty reply from server"
  ["raw_response"]=>
  bool(false)
  ["response"]=>
  NULL
  ["id":"Bitcoin":private]=>
  int(1)
}

The library I use :

// Optionally, you can specify a host and port.

// Defaults are:
//  host = localhost
//  port = 8332
//  proto = http

// This will set the protocol to HTTPS and some CURL flags
$bitcoin->setSSL('/full/path/to/mycertificate.cert');

// Make calls to bitcoind as methods for your object. Responses are returned as an array.
// Examples:
$bitcoin->getinfo();
$bitcoin->getrawtransaction('0e3e2357e806b6cdb1f70b54c3a3a17b6714ee1f0e68bebb44a74b1efd512098',1);

// The full response (not usually needed) is stored in $this->response while the raw JSON is stored in $this->raw_response

// When a call fails for any reason, it will return FALSE and put the error message in $this->error
// Example:
echo $bitcoin->error;

// The HTTP status code can be found in $this->status and will either be a valid HTTP status code or will be 0 if cURL was unable to connect.
// Example:
echo $bitcoin->status;

Thanks in advance.

  • Is Bitcoin running in RPC mode on both computers? What port do you have Bitcoin configured to use for RPC? – Nick ODell Jan 24 '17 at 20:01
  • I resolved it using bitcoind commands -server -rpcuser -rpcpassword – smoumou Jan 24 '17 at 20:11
  • don't know why on windows either with bitcoin-core or bitoind I cannot update and set the bitcoin.conf file. It is always ignored – smoumou Jan 24 '17 at 20:12

    Are you putting the bitcoin.conf file in the right place? Are you restarting Bitcoin between attempts to configure it? Can you use -conf at command line to manually set the path to the configuration file? – Nick ODell Jan 24 '17 at 20:15
  • I already did all of that hundreds of times ... – smoumou Jan 24 '17 at 20:18

$bitcoin = new Bitcoin("rpcuser","rpcpassword","localhost","80");

Port 80 is HTTP - it should be 8332 (or 18332 for testnet) unless you have set another RPC port in the configuration file

  • I tried several ports : 8332 8333 80 – smoumou Jan 27 '17 at 21:50
