eos client offline signature for PHP

针对PHP的EOS RPC客户端，另外提供EOS-ECC方法和离线交易。

Install

composer.json

{
    "require": {
        "myxtype/eos-client": "dev-master"
    }
}

然后composer update即可。

或者直接 composer require myxtype/eos-client:dev-master

Initialization

use xtype\Eos\Client as EosClient;

$client = new EosClient('http://api-kylin.eosasia.one');

GuzzleHttp Options.

$client = new EosClient([
    'base_uri' => 'http://api-kylin.eosasia.one',
    'timeout' => 20,
]);

RPC

You can visit https://developers.eos.io/eosio-nodeos/v1.4.0/reference View all RPC Method.

• set version（设置版本）

// set version
$client->version(1);
// or
$client->version(1)->chain();
// or
$client->version('v1')->chain();

• chain

$chain = $client->chain();
// You can do this
// will visit http://api-kylin.eosasia.one/v1/chain/get_info
var_dump($chain->getInfo());
// or
var_dump($chain->get_info());
// or
var_dump($client->chain()->get_info()->chain_id);
// string(64) "5fff1dae8dc8e2fc4d5b23b2c7665c97f9e9d8edf2b6485a86ba311c25639191"

// get_block
var_dump($chain->getBlock(['block_num_or_id' => 5]));

• history

$history = $client->history();
var_dump($history->getTransaction([
    'id' => '5fff1dae8dc8e2fc4d5b23b2c7665c97f9e9d8edf2b6485a86ba311c25639191'
]));

• net

$net = $client->net();
var_dump($net->status());

• producer

$producer = $client->producer();

• wallet

$wallet = $client->wallet();
// Signature transaction if you have opened your wallet RPC
$wallet->sign_transaction([
    'txn' => '',
    'keys' => '',
    'id' => '',
]);

• Error（错误信息）

在使用RPC过程中，你可能需要获取错误信息

try {
    // get_block
    var_dump($client->chain()->getBlock(['id' => 5]));
} catch(\Exception $e) {
    var_dump($client->getError());
}

如果有错误信息，将返回一个类似下面的对象。

object(stdClass)#21 (3) {
  ["code"]=>
  int(500)
  ["message"]=>
  string(22) "Internal Service Error"
  ["error"]=>
  object(stdClass)#35 (4) {
    ["code"]=>
    int(3010008)
    ["name"]=>
    string(23) "block_id_type_exception"
    ["what"]=>
    string(16) "Invalid block ID"
    ["details"]=>
    array(1) {
      [0]=>
      object(stdClass)#18 (4) {
        ["message"]=>
        string(78) "Invalid Block number or ID, must be greater than 0 and less than 64 characters"
        ["file"]=>
        string(16) "chain_plugin.cpp"
        ["line_number"]=>
        int(1396)
        ["method"]=>
        string(9) "get_block"
      }
    }
  }
}

• notice（说明）

Interface parameters need to be filled in according to the official EOS document. These methods are not fixed. If EOS officially updates the interface, you can modify it directly according to the above, without updating the code of EosClient.

接口参数需要按照EOS官方文档来填写。这些方法都不是固定的，如果EOS官方更新了接口，你直接按照上面修改就行，不必更新EosClient的代码。

ECC

• privateToPublic

use xtype\Eos\Ecc;

$privateWif = '5**********';
$public = Ecc::privateToPublic($privateWif);
var_dump($public);
// EOS7nCpUfHCPqAhu2qkTXSPQYmFLAt58gsmdFRtGCD2CNYcnWdRd3

• randomKey

use xtype\Eos\Ecc;

// 随机生成私钥
$randomKey = Ecc::randomKey();
var_dump($randomKey);
// 5KBRW5yz1syzQcJCFUmnDeoxBX6JoZ3UpwQk5r6uKKFfGajM8SA

• seedPrivate

use xtype\Eos\Ecc;

$privateWif = Ecc::seedPrivate('secret');
var_dump($privateWif);
// 5J9YKiVU3AWNkCa2zfQpj1f2NAeMQhLsYU51N8NM28J1bMnmrEQ

• isValidPublic

• sign
