EOS Chain/Wallet RPC API的PHP开发包

介绍一个EOS Chain/Wallet RPC API的PHP开发包。

开始

你可以查看EOS的RPC API参考，但要注意缺少一些较新的方法。Wallet RPC API实现EOS v1.1.0 of RPC API reference。此外，这些文档中的一些示例也使用了过时的语法。

安装

composer require manamine/php-eos-rpc-sdk

配置

使用你最喜欢的RPC API主机和KEOSD在项目根目录中创建一个dotenv.env文件。你可以使用env.example作为模板：

cp .env.example .env

有一个漂亮的工厂方法来自动化实例所有依赖项：

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

示例

为了帮助你入门，运行一个简单的示例，它涵盖了所有API命令。

只需通过cli运行此命令即可查看所有命令的示例输出：

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

API方法

涵盖了几乎所有区块链和钱包API方法。

Prerequisites

需要设置钱包名称和密码

$eos->setWalletInfo("testwallet", "PW5Jb8RAZP6CBjjMLPser3T8i8k9hZXZkMBJ8kb1p6f6hAg2n68jY");

Push Transaction

    [
        [
            "account" => "eosio.token",

$trx = $eos->makeTransaction(
    [
        [
            "account" => "eosio.token",
            "name" => "transfer",

$trx_ids = $eos->pushTransactions(
    [
        $eos->makeTransaction(
            [
                [
                    "account" => "eosio.token",
                    "name" => "transfer",
                    "authorization" => [

                    ]
                ]
            ]
        ),
        $eos->makeTransaction(
            [
                [
                    "account" => "eosio.token",
                    "name" => "transfer",
                    "authorization" => [
                        [
                            "actor" => "tester",
                            "permission" => "active"

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

Push Action

推动一个操作

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

创建密钥对并返回

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

Tests

要运行测试套件，只需执行：

vendor/bin/phpunit

如果您想获得想象并检查代码覆盖率：

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

如果你真的很无聊，你可能想要运行一些静态分析：

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