Bitpay 架构体系初步分析
Bitpay-Insight接口分析-1
Bitpay-Insight接口分析-2
Bitpay-Insight接口分析-3
在Bitpay的架构中,我们发现bitcore-node中insight-api服务起了一个核心的承接作用,它既向下读取bitcoin节点中信息,又向上暴露rest服务,给区块链浏览器和钱包调用.

从源码index.js中,我们可以发现,它的服务包括:
// Block routes
// 块相关服务,一共4种,块列表,根据hash读取块信息,根据hash读取块原始信息(16进制),根据高度读取块信息.
var blocks = new BlockController(blockOptions);
app.get('/blocks', this.cacheShort(), blocks.list.bind(blocks));
app.get('/block/:blockHash', this.cacheShort(), blocks.checkBlockHash.bind(blocks), blocks.show.bind(blocks));
app.param('blockHash', blocks.block.bind(blocks));
app.get('/rawblock/:blockHash', this.cacheLong(), blocks.checkBlockHash.bind(blocks), blocks.showRaw.bind(blocks));
app.param('blockHash', blocks.rawBlock.bind(blocks));
app.get('/block-index/:height', this.cacheShort(), blocks.blockIndex.bind(blocks));
app.param('height', blocks.blockIndex.bind(blocks));
// Transaction routes
// 交易相关服务,一共4种,根据交易id读取交易信息,交易列表,发送交易(post),根据交易id读取交易原始信息(16进制)
var transactions = new TxController(this.node, this.translateAddresses);
app.get('/tx/:txid', this.cacheShort(), transactions.show.bind(transactions));
app.param('txid', transactions.transaction.bind(transactions));
app.get('/txs', this.cacheShort(), transactions.list.bind(transactions));
app.post('/tx/send', transactions.send.bind(transactions));
// Raw Routes
app.get('/rawtx/:txid', this.cacheLong(), transactions.showRaw.bind(transactions));
app.param('txid', transactions.rawTransaction.bind(transactions));
// Address routes
// 地址相关服务,一共6种,地址交易显示,未发费utxo显示,多地相关址utxo显示(get+post),多地址相关交易显示(get+post)
var addresses = new AddressController(this.node, this.translateAddresses);
app.get('/addr/:addr', this.cacheShort(), addresses.checkAddrs.bind(addresses), addresses.show.bind(addresses));
app.get('/addr/:addr/utxo', this.cacheShort(), addresses.checkAddrs.bind(addresses), addresses.utxo.bind(addresses));
app.get('/addrs/:addrs/utxo', this.cacheShort(), addresses.checkAddrs.bind(addresses), addresses.multiutxo.bind(addresses));
app.post('/addrs/utxo', this.cacheShort(), addresses.checkAddrs.bind(addresses), addresses.multiutxo.bind(addresses));
app.get('/addrs/:addrs/txs', this.cacheShort(), addresses.checkAddrs.bind(addresses), addresses.multitxs.bind(addresses));
app.post('/addrs/txs', this.cacheShort(), addresses.checkAddrs.bind(addresses), addresses.multitxs.bind(addresses));
// Address property routes
// 地址属性相关服务,一共4种,地址余额,地址总接收值,地址总发送值,未确认(6块)总额
app.get('/addr/:addr/balance', this.cacheShort(), addresses.checkAddrs.bind(addresses), addresses.balance.bind(addresses));
app.get('/addr/:addr/totalReceived', this.cacheShort(), addresses.checkAddrs.bind(addresses), addresses.totalReceived.bind(addresses));
app.get('/addr/:addr/totalSent', this.cacheShort(), addresses.checkAddrs.bind(addresses), addresses.totalSent.bind(addresses));
app.get('/addr/:addr/unconfirmedBalance', this.cacheShort(), addresses.checkAddrs.bind(addresses), addresses.unconfirmedBalance.bind(addresses));
// Status route
// 状态相关服务,一共4种,服务状态,同步信息,连接节点信息,版本号
var status = new StatusController(this.node);
app.get('/status', this.cacheShort(), status.show.bind(status));
app.get('/sync', this.cacheShort(), status.sync.bind(status));
app.get('/peer', this.cacheShort(), status.peer.bind(status));
app.get('/version', this.cacheShort(), status.version.bind(status));
// messages routes
// 消息通知服务,一共2种,获取消息,验证消息(这个是bitpay提供的bitcore-message)
var messages = new MessagesController(this.node);
app.get('/messages/verify', messages.verify.bind(messages));
app.post('/messages/verify', messages.verify.bind(messages));
// Utils route
// 工具服务,目前就一种,手续费评估
var utils = new UtilsController(this.node);
app.get('/utils/estimatefee', utils.estimateFee.bind(utils));
// Currency
// 汇率服务,提供kraken提供的当前价格.
var currency = new CurrencyController({
node: this.node,
currencyRefresh: this.currencyRefresh,
currency: this.currency
});
app.get('/currency', currency.index.bind(currency));
// Other api endpoints
// 其他浏览器支持的币种信息
app.get('/explorers' , this._getExplorers.bind(this));
下面就根据各个模块,从最新的5.0.0-beta.44接口提供者那里获取真实的交互,以便于后续调整和对接.
