介紹一個EOS Chain/Wallet RPC API的PHP開發包。

開始

你可以檢視EOS的RPC API參考，但要注意缺少一些較新的方法。Wallet RPC API實現EOS v1.1.0 of RPC API reference。此外，這些文件中的一些示例也使用了過時的語法。

安裝

composer require manamine/php-eos-rpc-sdk

配置

使用你最喜歡的RPC API主機和KEOSD在專案根目錄中建立一個dotenv.env檔案。你可以使用env.example作為模板：

cp .env.example .env
 

有一個漂亮的工廠方法來自動化例項所有依賴項：

$api = (new ChainFactory)->api();
$walapi = (new WalletFactory)->api();
$eos = (new EosRpc($api, $walapi));

示例

為了幫助你入門，執行一個簡單的示例，它涵蓋了所有API命令。

只需通過cli執行此命令即可檢視所有命令的示例輸出：

cd examples
php chain.php
php wallet.php
php eosrpc.php

            ]
        )
    ]
);
foreach ($trx_ids as $key => $value) {
    echo $trx_ids[$key]['transaction_id'] . PHP_EOL;
}

Push Action

推動一個操作

echo $eos->pushAction("eosio", "buyram", ["payer"=>"tester","receiver"=>"tester","quant"=>"1.0000 EOS"], ["actor"=>"tester","permission"=>"active"]);

Transfer

交易支付

echo $eos->transfer("user", "tester", "1.0000 EOS", "memo");

Create Key Pair

建立金鑰對並返回

$keyPair = $eos->createKeyPair("K1");
echo "$keyPair[0], $keyPair[1]";

Tests

要執行測試套件，只需執行：

vendor/bin/phpunit

如果您想獲得想象並檢查程式碼覆蓋率：

vendor/bin/phpunit --coverage-html tests/coverage

如果你真的很無聊，你可能想要執行一些靜態分析：

vendor/bin/phpmetrics --report-html="tests/static" .
