no you use the original library. the one i use has been modified to replace the insecure fopen with curl and also never disclose error information

# Can't connect locally with API

(Asked by: username_0 on 2014-03-31)

I try to connect locally with bitcoin client using the API but I get 404 on request

```
 testnet=1
 server = 1
 rpcport=8332
 rpcuser=myuser
 rpcpassword=mypass

```

I was installing bitcoind on ubuntu server with `apt-get install bitcoind`

**PHP API Call**

```
 $_credintials = array('btc' =>'http://myuser:mypass@127.0.0.1:8332');
 //or 
 $_credintials = array('btc' =>'http://myuser:mypass@127.0.0.1:18332');
 $this->load->library('jsonRPCClient');
 $this->bitcoin = new jsonRPCClient($this->_credintials['btc']);

```

var\_dump();

```
Message: fopen(http://...@127.0.0.1:8332): failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found 

```

**Update**

Compiling bitcoind from github resolved the issue

first of all, you shouldn't be using fopen.
second of all you you obviously don't have rpcallowip set to whatever your ip is.

two things that will help you here:

this modified jsonrpc written by Gweedo is a secure way to connect to rpc in php. it uses curl instead of fopen. additionally, i modified this to return arrays instead of throwing exceptions, allowing you to keep log errors from your scripts silently or ignore them all together:

**name this JsonRPCClient.php**

```

 */
 class jsonRPCClient {
private $debug;
private $url;
private $id;
private $notification = false;
public function __construct($url,$debug = false) {
    $this->url = $url;
    empty($proxy) ? $this->proxy = '' : $this->proxy = $proxy;
    empty($debug) ? $this->debug = false : $this->debug = true;
    $this->id = 1;
}
public function setRPCNotification($notification) {
    empty($notification) ? $this->notification = false : $this->notification = true;
}
public function __call($method,$params) {
    if (!is_scalar($method)) { throw new Exception('Method name has no scalar value'); }              
    if (is_array($params)) { $params = array_values($params);}else{ throw new Exception('Params must be given as array'); }
    if ($this->notification) {$currentId = NULL; }else{ $currentId = $this->id;}
    $request = array( 'method' => $method, 'params' => $params, 'id' => $currentId );
    $request = json_encode($request);
    $this->debug && $this->debug.='***** Request *****'."\n".$request."\n".'***** End Of request *****'."\n\n";
    $ch = curl_init($this->url);
    curl_setopt($ch,CURLOPT_RETURNTRANSFER, true);

    $response = json_decode(curl_exec($ch),true);
    curl_close($ch);
    if ($this->debug) { echo nl2br($debug); }
    if (!$this->notification) {
            if ($response['id'] != $currentId) { return $response; }
            if (!is_null($response['error'])) { return $response; } 
            return $response['result'];
    }else{
            return true;
    }
}
}

```

a basic wallet.class.php for you to use

**name this wallet.class.php**

```
class Wallet {  
public $ip;
public $port;
public $username;
public $password;
public $Client;
public $credentials;
function Wallet($credentials)
{
    foreach($credentials as $row)
    {
        $ip = $row["ip"];
        $us = $row["user"];
        $pa = $row["pass"];
        $po = $row["port"];
        $ac = $row["acr"];
    }
    $this->ip        = $ip;
    $this->username  = $us;
    $this->password  = $pa;
    $this->port      = $po;
    $this->acronym   = $ac;
    $this->Client    = new jsonRPCClient('http://' . $this->username . ':' .$this->password . '@' . $this->ip . ':' . $this->port);
    return true;
}
}

```

now to use this functionality you simply do the following, lets call it **test.php**

```
require_once 'jsonRPCClient.php';
require_once 'class.wallet.php';
$credentials = array();
$credentials["ip"]   = '127.0.0.1';//your ip
$credentials["user"] = 'foo';//your username
$credentials["pass"] = 'bar';//your password
$credentials["port"] = '1337';//your port
$credentials["acr"]  = 'btc';
$rpc = new Wallet($credentials);//this returns true if no error during connection.
if($rpc === true) {
    $info =$rpc->Client->getinfo(); //try a basic rpc command
    echo '<pre>'; //make sure the array is printed neatly to the screen
    print_r($info, false); //dump the info to the screen
}else{
    print_r($rpc, false);//should dump the error for you
}

```

hope this helped, and good luck with your script.
