如何使用php在shopify rest api中创建分页

Question

我在 php 中创建了 curl 以使用 shopify product rest API。 现在我想在其中创建分页。

如何创造？

Link: "<https://{shop}.myshopify.com/admin/api/{version}/products.json?page_info={page_info}&limit={limit}>; rel={next}, <https://{shop}.myshopify.com/admin/api/{version}/products.json?page_info={page_info}&limit={limit}>; rel={previous}"

如何使用链接？

谢谢

下面的功能可以帮助你。 在 PHP/Laravel 中使用 API 获取数据

public function request($method,$url,$param = []){
    $client = new \GuzzleHttp\Client();
    $url = 'https://'.$this->username.':'.$this->password.'@'.$this->domain.'/admin/api/2019-10/'.$url;
    $parameters = [
        'headers' => [
            'Content-Type' => 'application/json',
            'Accept' => 'application/json'
        ]
    ];
    if(!empty($param)){ $parameters['json'] = $param;}
    $response = $client->request($method, $url,$parameters);
    $responseHeaders = $response->getHeaders();
    $tokenType = 'next';
    if(array_key_exists('Link',$responseHeaders)){
        $link = $responseHeaders['Link'][0];
        $tokenType  = strpos($link,'rel="next') !== false ? "next" : "previous";
        $tobeReplace = ["<",">",'rel="next"',";",'rel="previous"'];
        $tobeReplaceWith = ["","","",""];
        parse_str(parse_url(str_replace($tobeReplace,$tobeReplaceWith,$link),PHP_URL_QUERY),$op);
        $pageToken = trim($op['page_info']);
    }
    $rateLimit = explode('/', $responseHeaders["X-Shopify-Shop-Api-Call-Limit"][0]);
    $usedLimitPercentage = (100*$rateLimit[0])/$rateLimit[1];
    if($usedLimitPercentage > 95){sleep(5);}
    $responseBody = json_decode($response->getBody(),true);
    $r['resource'] =  (is_array($responseBody) && count($responseBody) > 0) ? array_shift($responseBody) : $responseBody;
    $r[$tokenType]['page_token'] = isset($pageToken) ? $pageToken : null;
    return $r;
}

此函数的示例用法

$product_ids = [];
$nextPageToken = null;
do{
    $response = $shop->request('get','products.json?limit=250&page_info='.$nextPageToken);
    foreach($response['resource'] as $product){
        array_push($product_ids, $product['id']);
    }
    $nextPageToken = $response['next']['page_token'] ?? null;
}while($nextPageToken != null);

如何从 api 请求 shopify graphql-admin-api？

Answer 2

从 API 版本 2019-07 开始，您确实需要使用基于游标的分页。

首先进行正常的 API 调用，包括标头响应。

然后在标头响应中，您将看到 link : ... with rel next or previous。

提取 page_info，然后使用 page_info 再次调用。

第一个调用是这样的：

https://...:...@xyz.myshopify.com/admin/api/2019-10/products.json?limit=2&published_status=published

然后第二个电话是

https://...:...@xyz.myshopify.com/admin/api/2019-10/products.json?limit=2&page_info=asdfas1321asdf3as1f651saf61s3f1x32v1akjhfasdj

当您进行第二次调用时，删除所有过滤器，因为过滤器将从第一次调用中应用。

顺便说一句：如果您在浏览器中测试由于链接在尖括号中的方式，它将被隐藏，因此只需在您的开发人员环境中查看源代码。

Rest API没有下一个功能。 您正在弥补。 如果要使用下一个分页样式的调用，请改用GraphQL API终结点，并在此处使用光标功能，该功能内置了下一个和上一个概念。

因此，您可以用与Rest API兼容的实际页码替换下一个愿望，或者切换到GraphQL并使用游标提供下一个和上一个。
