PHP functions not working in bitcoin JSON-RPC version 16 (bitcoin-cli is working properly) 2 Bitcoin Core in Docker container: Could not connect to the server. Controlling Bitcoin Core Run bitcoind or bitcoin-qt -server. You can control it via the command-line bitcoin-cli utility or by HTTP JSON-RPC commands. You must create a gasthausamflughafen.de configuration file setting an rpcuser and rpcpassword; see Running Bitcoin for details. Oct 31, · bitcoincore-rpc - contains an implementation of an rpc client that exposes the Bitcoin Core JSON-RPC APIs as rust functions. bitcoincore-rpc-json - contains rust data structures that represent the json responses from the Bitcoin Core JSON-RPC APIs. bitcoincore-rpc depends on this.

If you still can't get it to work go back to your php. Be sure you turn the error messages off again before you go live. Sign up to join this community.

Carlos De la Garza. Do you mind pasting the error message? Active Oldest Votes. With PHP7, sudo apt-get install php-curl Once installed make sure its enabled. Once I have it running as php script on terminal window, having also apache2 running with default index.
Don't worry if too long to explain, I will study web programming at some point. I have instaled Curl on my webserver curl, when I do a simply curl request from my server it gives me error like: 7 Failed to connect to Ok I was able to recreate this same error message when my node is not running, or when I run the bitcoin core GUI client.
It works fine when I run bitcoind. I assume you're running bitcoind? And works fine with localhost too. Sign up or log in Sign up using Google. Sign up using Facebook.

As a final fallback, you can directly use manually-chosen rpcuser and rpcpassword configuration parametersbut you must ensure that you choose a strong and unique passphrase and still don't use insecure networks, as mentioned above.
Secure string handling: The RPC interface does not guarantee any escaping of data beyond what's necessary to encode it as JSON, although it does usually provide serialized data using a hex representation of the bytes. If you use RPC data in your programs or provide its data to other programs, you must ensure any problem strings are properly escaped. For this reason, and other non-security reasons, it is recommended to display all serialized data in hex form only.
State that can be queried via RPCs is guaranteed to be at least up-to-date with the chain state immediately prior to the call's execution.
However, the state returned by RPCs that reflect the mempool may not be up-to-date with the current mempool state. The mempool state returned via an RPC is consistent with itself and with the chain state at the time of the call. Thus, the mempool state only encompasses transactions that are considered mine-able by the node at the time of the RPC. The mempool state returned via an RPC reflects all effects of mempool and chain state related RPCs that returned prior to this call.
The wallet state returned via an RPC is consistent with itself and with the chain state at the time of the call. The effects of all blocks and transactions in blocks at the time of the call is reflected in the state of all wallet transactions. For example, if a block contains transactions that conflicted with mempool transactions, the wallet would reflect the removal of these mempool transactions in the state.
However, the wallet may not be up-to-date with the current state of the mempool or the state of the mempool by an RPC that returned before this RPC. There is a known issue in the JSON-RPC interface that can cause a node to crash if too many http connections are being opened at the same time because the system runs out of available file descriptors.
To prevent this from happening you might want to increase the number of maximum allowed file descriptors in your system and try to prevent opening too many connections to your JSON-RPC interface at the same time if this is under your control. It is hard to give general advice since this depends on your system but if you make several hundred requests at once you are definitely at risk of encountering this issue.

Security The RPC interface allows other programs to control Bitcoin Core, including the ability to spend funds from your wallets, affect consensus verification, read private data, and otherwise perform operations that can cause loss of money, data, or privacy. RPC consistency guarantees State that can be queried via RPCs is guaranteed to be at least up-to-date with the chain state immediately prior to the call's execution.
Transaction Pool The mempool state returned via an RPC is consistent with itself and with the chain state at the time of the call.
