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);
