An API client for Filecoin implemented in Java

Quick Start

At present, this artifact has not been published to Maven central repository, so you should install locally

mvn clean install

For general projects

(1) import dependency in pom.xml

<dependency>
    <groupId>org.rockyang</groupId>
    <artifactId>filecoin-api-client</artifactId>
    <version>0.0.1</version>
</dependency>

(2) initialize Filecoin instance

Filecoin filecoin = new Filecoin("http://127.0.0.1:3453", false);

For SpringBoot projects

(1) import dependency in pom.xml, and you do not need to import filecoin-api-client in additional.

<dependency>
    <groupId>org.rockyang</groupId>
    <artifactId>filecoin-api-client-spring-boot-starter</artifactId>
    <version>0.0.1</version>
</dependency>

(2) set log-debug and api-base-url in application.properties

# switch to open http debug log
filecoin.log-debug=true
# filecoin rpc api base url
filecoin.api-base-url=http://127.0.0.1:3453

(3) use the Filecoin instance by @Autowired or @Resource annotation any where you want to do.

public class FilecoinController {

	@Autowired
	private Filecoin filecoin;
}

Usage

// create a new addresss
String address = filecoin.newAddress();

// fetch all address of current node
List<String> addresses = filecoin.getAddressList();

// export an address
String address = "t1b3keswmeuk4tipp5egjbk3aoag56g5zd3cle2va";
KeyInfo keyInfo = filecoin.walletExport(address);

// import wallet
String privateKey = "pdHwTOrJXnAGvQ0861k66xRsiT7N3Ms8IGte3nT837E=";
String address = filecoin.walletImport(privateKey);

// get balance 
String address = "t1esjjrygs7adcfbjnodbpdjzulzobznnln4tmsxq";
BigDecimal balance = filecoin.getBalance(address);
logger.info(balance);

// send transaction  
String from = "t16cgjiwgypve4uup27uk4xgppgd3i4nsldpid6ii";
String to = "t1esjjrygs7adcfbjnodbpdjzulzobznnln4tmsxq";
BigDecimal value = BigDecimal.valueOf(123.456);
BigDecimal gasPrice = BigDecimal.valueOf(0.001);
Integer gasLimit = 300;
String cid = filecoin.sendTransaction(from, to, value, gasPrice, gasLimit);

// get transction status
String cid = "zDPWYqFCtwpgqBEth4wFK53D8Sm9UGxhrL1tueb4RrgFDQLoKC1P";
MessageStatusRes.Message message = filecoin.getTransaction(cid);
