Title: [solved] http error from json-rpc in php Post by: kohlanta on March 05, 2013, 09:56:25 PM I am using the json-rpc php library from the bitcoin wiki (http://jsonrpcphp.org/) to send commands to my bitcoind instance. For the most part, it works as expected, but occasionally, when I use the sendtoaddress command, it will return one of the following errors:
Code: fopen(http://...@localhost:8334/): failed to open stream: HTTP request failed! HTTP/1.1 500 Internal Server Error Code: fopen(http://...@localhost:8334/): failed to open stream: HTTP request failed! This ambiguity is a problem for me. What I would really like is for the jsonrpc client to return a meaningful error when it cannot process the request (such as insufficient funds) and to return the usual output (txid) when sendtoaddress is successfully executed. I'm most comfortable in php, but am willing to learn other languages to achieve the same ends. Ultimately I need to take addresses/amounts from a mysql database and construct transactions in my bitcoind server. So, if anyone knows how to make this work in php or another language, perhaps perl or ruby or python and can walk me though it, and it works as described, 5 btc will be yours.

Or try cURL! And try taking the http:// outta there. And if it helps, here's an example on how to do it: http://pastebin.com/YCYb0nPv (http://pastebin.com/YCYb0nPv) Let me know if any of these works.

I'll play around with this and get back to you.

When you try to send coins if there are insufficent funds bitcoin will return an error which will cause json to throw an exception. In this case you should include checks:
Quote $balance = $bitcoind->getbalance(<account>); $fee = 0.0005; if($balance - $fee >= .00000001) $bitcoind->sendto(); else echo "Insufficient Funds"; Title: Re: [5 btc bounty] http error from json-rpc in php Post by: gweedo on March 06, 2013, 04:13:56 AM Your getting that error cause your script can't talk to your bitcoind, make sure you use the allowip, make sure you have the server=1, and rpcuser and rpcpass commands in your config file.
