batch request issues (json 2.0)

[TrantorRWS]

I just tried to compile latest dcrd code that should support batch request. PR https://github.com/decred/dcrd/pull/841 I tested to run a pool with NOMP but it failed when a request with no parameter is send to daemon:

[{"jsonrpc":"1.0","result":{"isvalid":true,"address":"xxxxxxxxxx"},"error":null,"id":1518626515519},

It seems that you pointed this issue here : https://github.com/decred/dcrd/pull/841#issuecomment-361356019

Tested in mainnet and testnet with two different version of NOMP

Looks like the rpc you called requires at least a param"error":{"code":-8,"message":"Failed to parse request: wrong number of params (expected between 1 and 2, received 0)"}. Provide the rpc that failed, thanks.

The only information about batch RPC request I can find in the sourcee code is:

        var batchRpcCalls = [
            ['validateaddress', [options.address]],
            ['getdifficulty', []],
            ['getinfo', []],
            ['getmininginfo', []],
            ['submitblock', []]
];

If I try to send submit block with dcrctl I got:

./dcrctl -j submitblock
submitblock command: wrong number of params (expected between 1 and 2, received 0) (code: ErrNumParams)
Usage:
  submitblock "hexblock" ({"workid":"value"})

the rpc documentation should have what you need https://github.com/decred/dcrd/blob/master/docs/json_rpc_api.md

I'm going to close this as it does not appear to be a bug with dcrd, rather an issue in how it's being called.
