Only one page of product got with rest admin api - laravel

Question

I have so many pages of products on my development store.But when I try to use products.json to get all of my products, it only take 50 listings(one page).Could anybody solve my doubt?
<?php
$url = 'https://myshopifystore/admin/api/2019-07/products.json';
$result = file_get_contents($url);
$data = json_decode($result, true);
dd($data);
my result like this picture:

Answer 1

The limit property on the request has a default of 50 up to 250. In case you want more use a loop to search though every page until the end.
GET /admin/api/2019-07/products.json?limit=250?page=1
Use
GET /admin/api/2019-07/products/count.json
to get the total product you want to search.

EDIT 1 : The paginated ?page= is now deprecated. It will be remove in version 2020-07. You should use cursor-based pagination.

Answer 2

Below function can help to fetch resources with cursor based pagination in new shopify API
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;
}
using above function in controller
$ids = [];
$nextPageToken = null;
do{
$response = $shop->request('get','products.json?limit=250&page_info='.$nextPageToken.'&rel=next');
foreach($response['resource'] as $product){
array_push($ids, $product['id']);
}
$nextPageToken = $response['next']['page_token'] ?? null;
}while($nextPageToken != null);
