PHP比特币开发教程：去中心化交易所OceanOne下单买卖比特币

以太坊钱包imtoken安装 2023-01-17 02:17:30

上一章节介绍了Exincore，1秒即可完成资产的市价交易。如果你想限价买卖，或者买卖一些exincore不支持的资产，你需要OceanOne。

选项 2：Ocean.One Exchange 上的挂单

Ocean.one是一个基于Mixin Network的去中心化交易所，具有一流的性能。您可以在OceanOne上交易任何资产，您只需要将您的币转入OceanOne，在交易备忘录中写入交易信息，OceanOne会在市场上列出您的交易需求，交易成功后，会转入标的将货币存入你的 MixinNetwork 账户，它具有三大特点和优势：

预备知识：

首先需要创建一个机器人，方法在教程一中。

安装依赖

正如我们在教程 1 中提到的，我们需要依赖 mixin-sdk-php，您应该先安装它。

安装依赖库

第四课，上一课已经安装好了。

将代币存入 Mixin Network，并读取其余额。

下面演示用USDT购买BTC或用BTC购买USDT。交易前，请检查钱包地址。完整步骤如下：

比特币和USDT的充值地址是一样的。

  const BTC_ASSET_ID     = "c6d0c728-2624-429b-8e0d-d9d19b6592fa";
  const EOS_ASSET_ID     = "6cfe566e-4aad-470b-8c9a-2fd35b49c68d";
  const USDT_ASSET_ID    = "815b0b1a-2764-3736-8faa-42d694fa620a";
  $mixinSdk_eachAccountInstance = new MixinSDK(GenerateConfigByCSV($data));
  $asset_info = $mixinSdk_eachAccountInstance->Wallet()->readAsset(BTC_ASSET_ID);
  print_r("Bitcoin wallet address is :".$asset_info["public_key"]."\n");
  print_r("Bitcoin wallet balance is :".$asset_info["balance"]."\n");

获取Ocean.one的市场价格信息

如何查看Ocean.one市场的价格信息？您需要知道交易的基础货币是什么。如果你想买比特币，卖USDT，那么基础货币就是USDT；如果你想买USDT，卖比特币，那么基础货币就是比特币。

if ( $ocmd == '1') { getOceanOneMarketInfos(XIN_ASSET_ID,USDT_ASSET_ID);}
function getOceanOneMarketInfos($targetCoin, $baseCoin)  {
  $client = new GuzzleHttp\Client();
  $baseUrl = "https://events.ocean.one/markets/".$targetCoin."-".$baseCoin."/book";
  $res = $client->request('GET', $baseUrl, [
      ]);
  if ($res->getStatusCode() == "200") {
    // echo $res->getStatusCode() . PHP_EOL;
    $resInfo = json_decode($res->getBody(), true);
    echo "Side | Price | Amount | Funds" . PHP_EOL;
    foreach ($resInfo["data"]["data"]["asks"] as $key => $exchange) {
      echo $exchange["side"] . " " . $exchange["price"] . " " . $exchange["amount"] ." " . $exchange["funds"] . PHP_EOL;
    }
    foreach ($resInfo["data"]["data"]["bids"] as $key => $exchange) {
      echo $exchange["side"] . " " . $exchange["price"] . " " . $exchange["amount"] ." " . $exchange["funds"] . PHP_EOL;
    }
  }
}

交易前，创建一个备忘录！

第二章基于Mixin Network的PHP比特币开发教程：机器人接受比特币并立即退款给用户三大比特币交易所，转账我们已经学会了，这里介绍如何告诉Ocean.one我们转账给它的目的是什么，并将所有信息放在备忘录中。

function GenerateOrderMemo($side, $asset, $price) :string {
  $memo = base64_encode(MessagePack::pack([
                       'S' => $side,
                       'A' => Uuid::fromString($asset)->getBytes(),
                       'P' => $price,
                       'T' => 'L',
                       ]));
  return $memo;
}

卖XIN的例子

将您计划出售的XIN转给Ocean.one（OCEANONE_BOT）三大比特币交易所，并将您计划兑换的目标虚拟资产的UUID放入memo中。

const OCEANONE_BOT     = "aaff5bef-42fb-4c9f-90e0-29f69176b7d4";
const USDT_ASSET_ID    = "815b0b1a-2764-3736-8faa-42d694fa620a";
const XIN_ASSET_ID     = "c94ac88f-4671-3976-b60a-09064f1811e8";
if ( $ocmd == 's1') {
  $p = readline("Input the Price of XIN/USDT: ");
  $a = readline("Input the Amount of XIN: ");
  $tMemo = GenerateOrderMemo("A",USDT_ASSET_ID,$p);
  echo $tMemo .  PHP_EOL;
  $mixinSdk_WalletInstance = GenerateWalletSDKFromCSV();
  $asset_info = $mixinSdk_WalletInstance->Wallet()->readAsset(XIN_ASSET_ID);
  print_r($asset_info);
  if ( (float) $asset_info["balance"] >= (float) $a ) {
    $transInfos = $mixinSdk_WalletInstance->Wallet()->transfer(XIN_ASSET_ID,OCEANONE_BOT,
                                                $mixinSdk_WalletInstance->getConfig()['default']['pin'],
                                                $a,
                                                $tMemo);
    print_r($transInfos);
    echo "The Order ID (trace_id) is: " . $transInfos["trace_id"] . PHP_EOL;
  } else { echo "Not enough XIN!\n";}
}

复制

如果您打算购买XIN，操作如下：

if ( $ocmd == 'b1') {
  $p = readline("Input the Price of XIN/USDT: ");
  $a = readline("Input the Amount of USDT: ");
  $tMemo = GenerateOrderMemo("B",XIN_ASSET_ID,$p);
  echo $tMemo .  PHP_EOL;
  $mixinSdk_WalletInstance = GenerateWalletSDKFromCSV();
  $asset_info = $mixinSdk_WalletInstance->Wallet()->readAsset(USDT_ASSET_ID);
  print_r($asset_info);
  if ( ((float) $asset_info["balance"] >= 1) && ( (float) $asset_info["balance"] >= (float) $a ) ) {
    $transInfos = $mixinSdk_WalletInstance->Wallet()->transfer(USDT_ASSET_ID,OCEANONE_BOT,
                                                $mixinSdk_WalletInstance->getConfig()['default']['pin'],
                                                $a,
                                                $tMemo);
    print_r($transInfos);
    echo "The Order ID (trace_id) is: " . $transInfos["trace_id"] . PHP_EOL;
  } else { echo "Not enough USDT!\n";}
}

取消挂单

Ocean.one将trace_id看做是一个订单，比如上例中b12eed67-6cf4-481f-b25b-dd41f28e1984就是订单号，我们用它来取消订单。

if ( $ocmd == 'c' ) {
  $mixinSdk_WalletInstance = GenerateWalletSDKFromCSV();
  $asset_info = $mixinSdk_WalletInstance->Wallet()->readAsset(CNB_ASSET_ID);
  if ( ((float) $asset_info["balance"] == 0) ) {
     echo "Please deposit some CNB to this Wallet!" . PHP_EOL;
  } else {
     $orderid = readline("Input the Order id ( trace_id ): ");
     $cMemo =  base64_encode(MessagePack::pack([
                           'O' => Uuid::fromString($orderid)->getBytes(),
                           ]));
     $transInfos = $mixinSdk_WalletInstance->Wallet()->transfer(CNB_ASSET_ID,OCEANONE_BOT,
                                                 $mixinSdk_WalletInstance->getConfig()['default']['pin'],
                                                 "0.00000001",
                                                 $cMemo);
     print_r($transInfos);
  }

通过读取资产余额确认到账

查看钱包余额。

if ($line == 'aw') {
  $mixinSdk_eachAccountInstance = GenerateWalletSDKFromCSV();
  $asset_info = $mixinSdk_eachAccountInstance->Wallet()->readAssets();
  foreach ($asset_info as $key => $asset) {

          "   ". $asset["public_key"].PHP_EOL;
