auroraclient

auroraclient is a HcNet Go SDK package that provides client access to a aurora server. It supports all endpoints exposed by the aurora API.

This project is maintained by the HcNet Development Foundation.

Getting Started

This library is aimed at developers building Go applications that interact with the HcNet network. It allows users to query the network and submit transactions to the network. The recommended transaction builder for Go programmers is txnbuild. Together, these two libraries provide a complete HcNet SDK.

Prerequisites
  • Go 1.10 or greater
Installing
  • Download the HcNet Go monorepo: git clone git@github.com:hcnet/go.git
  • Enter the source directory: cd $GOPATH/src/github.com/hcnet/go
  • Download external dependencies: dep ensure -v
Usage
    ...
    import hClient "github.com/hcnet/go/clients/auroraclient"
    ...

    // Use the default pubnet client
    client := hClient.DefaultPublicNetClient

    // Create an account request
    accountRequest := hClient.AccountRequest{AccountID: "GCLWGQPMKXQSPF776IU33AH4PZNOOWNAWGGKVTBQMIC5IMKUNP3E6NVU"}

    // Load the account detail from the network
    account, err := client.AccountDetail(accountRequest)
    if err != nil {
        fmt.Println(err)
        return
    }
    // Account contains information about the hcnet account
    fmt.Print(account)

For more examples, refer to the documentation.

Overview

Package auroraclient provides client access to a Aurora server, allowing an application to post transactions and look up ledger information.

This library provides an interface to the HcNet Aurora service. It supports the building of Go applications on top of the HcNet network (https://www.hcnet.org/). Transactions may be constructed using the sister package to this one, txnbuild (https://github.com/hcnet/go/tree/master/txnbuild), and then submitted with this client to any Aurora instance for processing onto the ledger. Together, these two libraries provide a complete HcNet SDK.

For more information and further examples, see https://www.hcnet.org/developers/go/reference/index.html.

Functions

Types

type AccountRequest 

type AccountRequest struct {
	AccountID string
	DataKey   string
}

AccountRequest struct contains data for making requests to the accounts endpoint of a aurora server. "AccountID" and "DataKey" fields should both be set when retrieving AccountData. When getting the AccountDetail, only "AccountID" needs to be set.

func (AccountRequest) BuildURL 

func (ar AccountRequest) BuildURL() (endpoint string, err error)

BuildURL creates the endpoint to be queried based on the data in the AccountRequest struct. If only AccountID is present, then the endpoint for account details is returned. If both AccounId and DataKey are present, then the endpoint for getting account data is returned

type AssetRequest 

type AssetRequest struct {
	ForAssetCode   string
	ForAssetIssuer string
	Order          Order
	Cursor         string
	Limit          uint
}

AssetRequest struct contains data for getting asset details from a aurora server. If "ForAssetCode" and "ForAssetIssuer" are not set, it returns all assets. The query parameters (Order, Cursor and Limit) are optional. All or none can be set.

func (AssetRequest) BuildURL 

func (ar AssetRequest) BuildURL() (endpoint string, err error)

BuildURL creates the endpoint to be queried based on the data in the AssetRequest struct. If no data is set, it defaults to the build the URL for all assets

type AssetType

type AuroraRequest 

type AuroraRequest interface {
	BuildURL() (string, error)
}

AuroraRequest contains methods implemented by request structs for aurora endpoints.
