/*
Package client implements NEO-specific JSON-RPC 2.0 client.
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 := client.Options{}
c, err := client.New(context.TODO(), endpoint, opts)
if err != nil {
log.Fatal(err)
}
if err := c.Ping(); err != nil {
log.Fatal(err)
}
resp, err := c.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.

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

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)
getstorage (lacks VM functionality)

/*
Package server implements NEO-specific JSON-RPC 2.0 server.
This package is currently in alpha and is subject to change.
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)
getstorage (lacks VM functionality)
gettxout (needs to be implemented in pkg/core/blockchain.go)
invoke (lacks VM functionality)
invokefunction (lacks VM functionality)
