Java对接Filecoin 充值上账流程

文章目录

一、描述

记录下这两天对接Filecoin充值的流程…

1.记录区块高度值
2.轮训区块高度值获取当前所属区块的Cids
3.拿到所属区块的Cids,获取区块中的区块消息
4.组装当前区块高度的所有区块消息-去重
5.比较去重之后的区块消息地址和自己的区块地址
6.匹配地址成功后,通过hash查询交易确认状态
7.确认状态成功,上账到交易所钱包
8.归集这个地址的充值金额到归集钱包地址

二、充值上账的流程

1、读取指定高度的TipSet【ChainGetTipSetByHeight】

返回数据只拿到所属区块的Cids

result –> Cids

/*查询指定高度的TipSet*/
public List<FilCid> getChainGetTipSetByHeight(Long blockNumber) {
    List<FilCid> filCids = new ArrayList<>();
    List<Object> info = new ArrayList<>();
    info.add(blockNumber);
    info.add(new ArrayList<>());
    Optional<String> response = FilHttpUtils.post(info, FilApiConfig.FIL_METHOD_CHAINGETTIPSETBYHEIGHT);
    if (response.isPresent()) {
        String body = response.get();
        if (StringUtils.isNotBlank(body)) {
            JSONObject jsonBody = JSONObject.parseObject(body);
            if (jsonBody != null) {
                String result = jsonBody.getString("result");
                if (StringUtils.isNotBlank(result)) {
                    JSONObject object = JSONObject.parseObject(result);
                    if (object != null) {
                        Long height = object.getLongValue("Height");
                        if (Long.compare(height, blockNumber) == 0) {
                            System.out.println("返回区块高度:" + height + "和查询区块高度和返回的一致...");
                            String cids = object.getString("Cids");
                            JSONArray jsonArray = JSONArray.parseArray(cids);
                            if (CollectionUtils.isNotEmpty(jsonArray)) {
                                for (Object o : jsonArray) {
                                    JSONObject cidObject = JSONObject.parseObject(o.toString());
                                    FilCid cid = FilCid.builder().cid(cidObject.get("/").toString()).build();
                                    filCids.add(cid);
                                }
                            }
                        }
                    }
                }
            }
        }
    }
    return filCids;
}

2、读取区块内消息【ChainGetBlockMessages】

返回数据拿到SecpkMessages、CID。组装地址、余额、哈希。

result –> SecpkMessages –> Message
result –> SecpkMessages –> CID

/*查询区块内的消息*/
public List<FilMessage> getChainGetBlockMessages(String cid) {
    List<FilMessage> filMessages = new ArrayList<>();
    JSONObject cidObj = new JSONObject();
    cidObj.put("/", cid);
    List<Object> info = new ArrayList<>();
    info.add(cidObj);
    Optional<String> response = FilHttpUtils.post(info, FilApiConfig.FIL_METHOD_CHAINGETBLOCKMESSAGES);
    if (response.isPresent()) {
        String body = response.get();
        if (StringUtils.isNotBlank(body)) {
            JSONObject jsonBody = JSONObject.parseObject(body);
            if (jsonBody != null) {
                String result = jsonBody.getString("result");
                if (StringUtils.isNotBlank(result)) {
                    JSONObject object = JSONObject.parseObject(result);
                    if (object != null) {
                        String secpkMessages = object.getString("SecpkMessages");
                        JSONArray jsonArray = JSONArray.parseArray(secpkMessages);
                        if (CollectionUtils.isNotEmpty(jsonArray)) {
                            for (Object secpkMessagesObj : jsonArray) {
                                JSONObject secpkMessagesJson = JSONObject.parseObject(secpkMessagesObj.toString());
                                if (secpkMessagesJson != null) {
                                    String message = secpkMessagesJson.getString("Message");
                                    if (StringUtils.isNotBlank(message)) {
                                        JSONObject messageObject = JSONObject.parseObject(message);
                                        if (messageObject != null) {
                                            String hashStr = secpkMessagesJson.getString("CID");
                                            String hash = "";
                                            if (StringUtils.isNotBlank(hashStr)) {
                                                JSONObject hashObject = JSONObject.parseObject(hashStr);
                                                if (hashObject != null) {
                                                    hash = hashObject.getString("/");
                                                }
                                            }
                                            String to = messageObject.getString("To");
                                            String from = messageObject.getString("From");
                                            String value = messageObject.getString("Value");
                                            FilMessage filMessage = FilMessage.builder().to(to).from(from).value(value).hash(hash).build();
                                            filMessages.add(filMessage);
                                        }
                                    }
                                }
                            }
                        }
                    }
                }
            }
        }
    }
    return filMessages;
}

3、累计区块消息去重

区块高度对应所属区块有多个,上账之前去重消息

System.out.println("1-区块高度去重之前的消息总数:" + filMessageList.size());
List<FilMessage> filMessageListCollect = filMessageList.stream().distinct().collect(Collectors.toList());
System.out.println("2-区块高度去重之后的消息总数:" + filMessageListCollect.size());

4、遍历匹配自己地址

/*轮训遍历匹配自己交易所地址数据*/
for (FilMessage filMessage : filMessageListCollect) {
    if (StringUtils.isNotBlank(filMessage.getTo()) && filMessage.getTo().equals(FIL_SELF_ADDRESS)) {
        System.out.println("区块高度:" + blockNumber + ",地址:" + filMessage.getTo() + ",充值到账地址和自己地址一致...");
        /*查询这笔交易的hash交易确认及交易状态*/
        int confirm = fileRecharge.transactionConfirm(filMessage.getHash());
        if (confirm == 1) {
            System.out.println(filMessage.getTo() + "  交易hash确认完成,上账到交易所钱包...");
        }
    }
}

5、确认交易状态

查询区块浏览器:Filfox的接口、区块链头接口判断交易是否确认

/*根据交易hash进行交易确认*/
public int transactionConfirm(String hash) {
    Optional<String> str = FilHttpUtils.get(FIL_URL_MESSAGE_ID + hash);
    if (str.isPresent()) {
        String urlinfo = str.get();
        try {
            JSONObject message = JSONObject.parseObject(urlinfo);
            if (message == null) {
                return 0;
            }
            JSONObject receipt = JSONObject.parseObject(message.getString("receipt"));
            if (receipt == null) {
                return 0;
            }
            long height = message.getLong("height") != null ? message.getLong("height") : 0L;
            if (receipt.getIntValue("exitCode") != 0) {
                return 0;
            }
            if (height == 0) {
                return 0;
            }
            /*获取最新区块高度*/
            long head = getBlockHeight();
            if (head - height > 10) {
                return 1;
            }
            System.out.println("查询Fil的交易hash确认失败!hash:" + hash);
        } catch (Exception e) {
            e.printStackTrace();
            return 0;
        }
    }
    return 0;
}

/*查询当前链头的区块高度*/
public Integer getBlockHeight() {
    Optional<String> response = FilHttpUtils.post(new ArrayList<>(), FilApiConfig.FIL_METHOD_CHAINHEAD);
    if (response.isPresent()) {
        String body = response.get();
        if (StringUtils.isNotBlank(body)) {
            JSONObject jsonBody = JSONObject.parseObject(body);
            if (jsonBody != null) {
                String result = jsonBody.getString("result");
                if (result != null) {
                    JSONObject object = JSONObject.parseObject(result);
                    if (object != null) {
                        int height = Integer.parseInt(object.getString("Height"));
                        return height;
                    }
                }
            }
        }
    }
    return 0;
}

五、总结

调用infura节点接口读取区块内消息时,有时接口响应很慢,几十秒的都有。用自己搭建的Filcoin Lotus节点响应很快1秒内。测试了调用infura节点多调用几次响应速度越来越快。
