Package rpcclient implements NEO-specific JSON-RPC 2.0 client.
|
|
|
|
This package itself is designed to be a thin layer on top of the regular JSON-RPC
|
|
interface provided by Neo implementations. Therefore the set of methods provided
|
|
by clients is exactly the same as available from servers and they use data types
|
|
that directly correspond to JSON data exchanged. While this is the most powerful
|
|
and direct interface, it at the same time is not very convenient for many
|
|
purposes, like the most popular one --- performing test invocations and
|
|
creating/sending transactions that will do something to the chain. Please check
|
|
subpackages for more convenient APIs.
|
|
|
|
# Subpackages
|
|
|
|
The overall structure can be seen as a number of layers built on top of rpcclient
|
|
and on top of each other with each package and each layer solving different
|
|
problems.
|
|
|
|
These layers are:
|
|
|
|
- Basic RPC API, rpcclient package itself.
|
|
|
|
- Generic invocation/transaction API represented by invoker, unwrap (auxiliary,
|
|
but very convenient) and actor packages. These allow to perform test
|
|
invocations with plain Go types, use historic states for these invocations,
|
|
get the execution results from reader functions and create/send transactions
|
|
that change something on-chain.
|
|
|
|
- Standard-specific wrappers that are implemented in nep11 and nep17 packages
|
|
(with common methods in neptoken). They implement the respective NEP-11 and
|
|
NEP-17 APIs both for safe (read-only) and state-changing methods. Safe methods
|
|
require an Invoker to be called, while Actor is used to create/send
|
|
transactions.
|
|
|
|
- Contract-specific wrappers for native contracts that include management, gas,
|
|
neo, oracle, policy and rolemgmt packages for the respective native contracts.
|
|
Complete contract functionality is exposed (reusing nep17 package for gas and
|
|
neo).
|
|
|
|
- Notary actor and contract, a bit special since it's a NeoGo protocol
|
|
extension, but notary package provides both the notary native contract wrapper
|
|
and a notary-specific actor implementation that allows to easily wrap any
|
|
transaction into a notary request.
|
|
|
|
- Non-native contract-specific wrappers, currently partially provided only for
|
|
NNS contract (it's still in development), at the moment that's mostly an
|
|
example of how contract-specific wrappers can be built for other dApps
|
|
(reusing invoker/actor layers it's pretty easy).

# Client

|
|
|
After creating a client instance with or without a ClientConfig
|
|
you can interact with the NEO blockchain by its exposed methods.
