PHP and bitcoinQT error when connecting via jsonRPC

[spunkybd]

I have set up my .conf file for bitcoin and a php script to connect to the RPC server. Whenever i try to connect through my web browser i get this error:

{"result":null,"error":{"code":-32700,"message":"Parse error"},"id":null}

Any tips?

The daemon had trouble parsing the json you sent it.

Without a code snippet, I can't help you any more than that.

The daemon had trouble parsing the json you sent it.

Without a code snippet, I can't help you any more than that.

Code:

/* Configuration variables for the JSON-RPC server */
$rpc_host = 'localhost';
$rpc_port = '8332';
$rpc_user = 'thisuser';
$rpc_pass = 'mypass';


require_once('jsonRPCClient.php');
$bc = new jsonRPCClient('http://' . $rpc_user . ':' . $rpc_pass . '@' . $rpc_host . ':' . $rpc_port);

Also conf:

Code:

# JSON-RPC options (for controlling a running Bitcoin/bitcoind process)
 
 # server=1 tells Bitcoin-QT to accept JSON-RPC commands.
 server=1
 
 # You must set rpcuser and rpcpassword to secure the JSON-RPC api
 rpcuser=thisuser
 rpcpassword=thispass
 
 # How many seconds bitcoin will wait for a complete RPC HTTP request.
 # after the HTTP connection is established. 
 rpctimeout=30
 
 # By default, only RPC connections from localhost are allowed.  Specify
 # as many rpcallowip= settings as you like to allow connections from
 # other hosts (and you may use * as a wildcard character):
 #rpcallowip=10.1.1.34
 rpcallowip=127.0.0.1
 rpcallowip=10.1.10.100
 rpcallowip=localhost
 
 # Listen for RPC connections on this TCP port:
 rpcport=8332

I'm assuming your username's and passes's are matching.

What function are you calling to get the error?

This here is supposed to grab the info from up there. It does so properly and tries to connect but i receive the error i posted up top.


require_once('jsonRPCClient.php');
$bc = new jsonRPCClient('http://' . $rpc_user . ':' . $rpc_pass . '@' . $rpc_host . ':' . $rpc_port);

[OdinHephaestus]

Why do you have...

Code:

rpcallowip=127.0.0.1
rpcallowip=localhost

These are the same thing, I would remove the "localhost" one, it is better to use the ip 127.0.0.1 for localhost. Not a hostname.

Way to nitpick.

As for your problem, change

Code:

$bc = new jsonRPCClient('http://' . $rpc_user . ':' . $rpc_pass . '@' . $rpc_host . ':' . $rpc_port);

to

Code:

$bc = new jsonRPCClient('http://' . $rpc_user . ':' . $rpc_pass . '@' . $rpc_host . ':' . $rpc_port, true);

This should give you a more in depth error log.

Barring that, try re-downloading the json-rpc library, it's possible yours might have been messed with. Were you playing with the code at all?

[spunkybd]

Ill try what you suggested then report back and then replace the json client.

EDIT:

Didnt work with the replaced RPC client or with the true statement

RPCclient im using:

Why do you have...

Code:

rpcallowip=127.0.0.1
rpcallowip=localhost

These are the same thing, I would remove the "localhost" one, it is better to use the ip 127.0.0.1 for localhost. Not a hostname.

Meh best practice where i come from is to use the hostname

Do you have a specific preference for cURL?

That should be removed

You only need the password in the URL not in the curl script.

Your a genius and i love you.

Thanks everyone for your help, its really appreciated. And when i become BTC rich i will think of you for a second.
