<p>I'm running the server with the batch command bitcoin-qt.exe -server 
Is there anything else I need to do to get the data from the network?</p>

Is the firewall allowing connections? Try your browser with http://127.0.0.1:8332 ... It should popup with credentials if all is well. Otherwise you may need a *bitcoin.conf* with *rpcallowip*

The credentials window shows up.In the meantime I've made some JSON requests without the library, I tried several API methods and all work except the 'getwork' method, was it removed completely? When I call it I'm getting the response  {"result":null,"error":{"code":-32601,"message":"Method not found"},"id":"anything"}

Are you using the latest version of Bitcoin? `getwork` has been removed in favor of `getblocktemplate`. Does `getblocktemplate` work?

Yes I'm using the latest version of Bitcoin, getblocktemplate works perfectly. Thank you for clarifying that.

# Bitcoin core server error when requesting data

(Asked by: username_0 on 2015-03-19)

I'm trying to interact with the bitcoin network with Bitcoin Core server and the JSON RPC PHP library found on the wiki here: <https://en.bitcoin.it/wiki/API_reference_%28JSON-RPC%>

My setup:

I installed the Bitcoin core client, created the bitcoin.conf file with the settings:

```
rpcuser=finder
rpcpassword=AcdfghHBTfYHTFytBG526
server=1
rpcport=8332

```

the wallet is synchronised with the network.

I tried the example on the wiki like this:

```
require_once 'jsonRPCClient.php';
$bitcoin = new   jsonRPCClient('http://finder:AcdfghHBTfYHTFytBG526@127.0.0.1:8332/');
print_r($bitcoin->getwork()); echo "\n";

```

When running the code I'm getting the error:

```
 Warning:  fopen(http://...@127.0.0.1:8332/): failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found
 in D:\xampp\htdocs\p\jsonRPCClient.php on line 132

```

I'm running the server with the batch command bitcoin-qt.exe -server
Is there anything else I need to do to get the data from the network?
