一、方法说明

二、功能使用

全局变量

$counter = 0;
function preStop($context) {
    $GLOBALS['fcLogger']->info("preStop ok");
}

function handler($event, $context) {
    global $counter;
    $counter += 2;
    return $counter;
}

获取请求参数

$info['body']       = $request->getBody()->getContents();
$info['queries']    = $request->getQueryParams(); //数组
$info['method']     = $request->getMethod(); // `GET`
$info['headers']    = $request->getHeaders(); // "Host":["fc.fe80.cn"]
$info['path']       = $request->getAttribute('path'); // `/aa/bb/cc`
$info['requestURI'] = $request->getAttribute('requestURI'); // `/aa/bb/cc?name=bb`
$info['clientIP']   = $request->getAttribute('clientIP'); // `116.171.4.22`

无密码操作对象存储

use RingCentral\Psr7\Response;
use OSS\OssClient;
use OSS\Core\OssException;

function handler($request, $context): Response
{
    $credentials = $context['credentials'];
    $resbody['oss']['list'] = getObjectList($credentials);
    return new Response(
        200,
        [
            'X-Powered-By' => 'nginx/1.28.0',
            'Content-Type' => 'application/json',
            'Access-Control-Allow-Origin' => '*',
            'Access-Control-Allow-Headers' => 'origin,accept,content-type',
        ],
        json_encode($resbody,JSON_UNESCAPED_UNICODE)
    );
}

function getObjectList($credentials){
    $accessKeyId = $credentials['accessKeyId'];
    $accessKeySecret = $credentials['accessKeySecret'];
    $securityToken = $credentials['securityToken'];
    $endpoint = 'http://oss-cn-chengdu.aliyuncs.com';
    $bucket = 'bucket';
    $ossClient = new OssClient($accessKeyId, $accessKeySecret, $endpoint, $securityToken);
    $options = array(
        'delimiter' => '/',
        'prefix' => "folder",
        'max-keys' => 100,
        'marker' => '',
    );

    $listObjectInfo = $ossClient->listObjects($bucket, $options);
    foreach ($listObject as $objectInfo) {
        // TODO
    }
    return $listObject;
}
