HTTP Proxy For Ethminer API

HTTP Proxy For ethminer TCP json-rpc 2.0 API

Since Ethminer does not have a HTTP API, this small go app allows you to consume the Ethminer API as HTTP.

Usage

Build the project and run from console:

go build .

ethminer-api-http-proxy --help

Only required flag is -miner, this your ethminer API address. Eg:

ethminer-api-http-proxy -miner 127.0.0.1:3333

If you want to change HTTP server address, use -serve flag. Eg:

ethminer-api-http-proxy -miner 127.0.0.1:3333 -serve :8085
ethminer-api-http-proxy -miner 127.0.0.1:3333 -serve 192.168.1.36:8085

And you can consume ethminer API as HTTP:

curl--request POST '127.0.0.1:8085' --header 'Content-Type: application/json' --data-raw '{"id":0,"jsonrpc":"2.0","method":"miner_getstatdetail"}'

HTTP API

There is no endpoints except /. Just Send POST requests to / with ethminer JSON request body.

You can find all ethminer requests from ethminer API Docs.

Note:

Since ethminer API using json-rpc 2.0 and TCP connection, API requests must have id field for request-response mapping. But you don't have to worry about it when you using this proxy. Because, this is HTTP.

So, just set id:0 when sending requests and ignore the id in responses, Eg:

//Request Body
{
  "id": 0, //doesn't matter what you send, just send integer
  "jsonrpc": "2.0",
  "method": "miner_ping"
}

//Response Body
{
  "id": 1241, //just ignore it
  "jsonrpc": "2.0",
  "result": "pong"
}

Caveats:

• For now, only tested on Windows 10, but probably works on linux either.
• ethminer API authorize not implemented. For safety, use your ethminer API in read-only mode. Details in ethminer API Docs.
• Important: Since this app have no tests and bad error handling, if this proxy app die because of an error or something and can't properly close the TCP connection with ethminer API, ethminer dies too. This is probably a bug in ethminer.

TODO:

• Write tests
• Write better error handling and make sure to close the TCP connection properly.
• Write better log messages.(actualy, write log messages...)
• Implement and test ethminer authorize for write oriented requests, provide safety.
• Proper HTTP status codes for bad, invalid ethminer API requests.
