/*
Package rpc implements NEO-specific JSON-RPC 2.0 client and server.
This package is currently in alpha and is subject to change.
Client
After creating a client instance with or without a ClientConfig
you can interact with the NEO blockchain by its exposed methods.
Some of the methods also allow to pass a verbose bool. This will
return a more pretty printed response from the server instead of
a raw hex string.
An example:
endpoint := "http://seed5.bridgeprotocol.io:10332"
opts := rpc.ClientOptions{}
client, err := rpc.NewClient(context.TODO(), endpoint, opts)
if err != nil {
log.Fatal(err)
}
if err := client.Ping(); err != nil {
log.Fatal(err)
}
resp, err := client.GetAccountState("ATySFJAbLW7QHsZGHScLhxq6EyNBxx3eFP")
if err != nil {
log.Fatal(err)
}
log.Println(resp.Result.ScriptHash)
log.Println(resp.Result.Balances)
TODO:
Merge structs so can be used by both server and client.
Add missing methods to client.
Allow client to connect using client cert.
More in-depth examples.
Supported methods
getblock
getaccountstate
invokescript
invokefunction
sendrawtransaction
invoke
getrawtransaction
Unsupported methods
validateaddress
getblocksysfee
getcontractstate
getrawmempool
getstorage
submitblock
gettxout
getassetstate
getpeers
getversion
getconnectioncount
getblockhash
getblockcount
getbestblockhash
Server
The server is written to support as much of the JSON-RPC 2.0 Spec as possible.
The server is run as part of the node currently.
TODO:
Implement HTTPS server.
Add remaining methods (Documented below).
Add Swagger spec and test using dredd in circleCI.
Example call
An example would be viewing the version of the node:
$ curl -X POST -d '{"jsonrpc": "2.0", "method": "getversion", "params": [], "id": 1}' http://localhost:20332
which would yield the response:
{
"jsonrpc" : "2.0",
"id" : 1,
"result" : {
"port" : 20333,
"useragent" : "/NEO-GO:0.36.0-dev/",
"nonce" : 9318417
}
}
Unsupported methods
getblocksysfee
getcontractstate (needs to be implemented in pkg/core/blockchain.go)
getrawmempool (needs to be implemented on in pkg/network/server.go)
getrawtransaction (needs to be implemented in pkg/core/blockchain.go)
