轻易云数据集成平台适配器SDK开发指南

轻易云数据集成平台通过标准化SDK实现与各类业务系统的快速对接。以下展示平台适配器SDK的核心实现逻辑，该方案已应用于500+企业系统集成场景。

SDK基础架构

适配器SDK作为连接轻易云平台与目标系统的桥梁，采用模块化设计：

namespace Adapter\PlatformName\SDK;

class PlatformNameSDK
{
    // 连接配置参数
    protected $connectorId = 'connectorId';
    protected $env = '';
    protected $host = '';
    protected $login = ['appKey' => 'xxxxxx', 'appSecret' => 'xxxxxxxx'];
    protected $token = null;
    protected $client = \GuzzleHttp\Client::class;

    // 初始化构造器
    public function __construct($connectorId, $params, string $env = '')
    {
        $this->connectorId = $connectorId;
        $this->host = $params['host'];
        $this->login = $params;
        $this->env = $env;
        $this->client = new \GuzzleHttp\Client();
    }
}

连接管理模块

轻易云平台采用智能token管理策略，支持自动续期和缓存机制：

public function connection()
{
    $cacheKey = $this->connectorId . $this->env;
    $token = Cache::get($cacheKey);

    if ($token) {
        $this->token = $token;
        return ['status' => true, 'token' => $token];
    }

    $url = $this->host . '/open-apis/auth/v3/tenant_access_token/internal';
    $response = $this->client->post($url, [
        'form_params' => $this->login,
        'headers' => ['Content-Type' => 'application/json']
    ]);

    $arr = json_decode((string)$response->getBody(), true);

    if ($arr['code'] == 0) {
        $this->token = $arr['tenant_access_token'];
        Cache::put($cacheKey, $this->token, $arr['expire'] - 100);
    }
    return $arr;
}

接口调用模块

轻易云平台提供安全可靠的接口调用机制，包含自动签名和异常处理：

public function invoke(string $api, $params = [], $method = 'POST')
{
    $url = $this->host . $api;
    $sign = $this->generateSign($params);
    $headers = [
        'accesstoken' => $this->token,
        'sign' => $sign,
        'Content-Type' => 'application/json'
    ];

    $options = [
        'http_errors' => false,
        'headers' => $headers
    ];

    if (strtoupper($method) === 'GET') {
        $options['query'] = $params;
        $response = $this->client->get($url, $options);
    } else {
        $options['body'] = json_encode($params);
        $response = $this->client->post($url, $options);
    }

    return json_decode((string)$response->getBody(), true);
}

protected function generateSign($params)
{
    return md5(json_encode($params).$this->login['appKey']);
}

该SDK方案已集成到轻易云数据集成平台的适配器开发框架中，开发者可通过可视化配置界面快速生成基础代码，大幅降低系统对接难度。平台支持自动化的token管理、请求签名和数据转换，确保企业级集成场景下的稳定性和安全性。
