使用php在shopify中添加脚本标记

Question

We are using this GitHub PHP library for adding javascript in to the head of shopify pages using script tag but we have got stuck somewhere,

it redirects well. We go to app screen to get permission also when we click on install it redirects to redirect page and gives error. in my error log.

Uncaught PHPShopify\Exception\ApiException: script_tag - expected Array to be a Hash in

This is our app code

<?php
require '/home/xxx/public_html/shopify/1/vendor/autoload.php';

$config = array(
    'ShopUrl' => 'xyyy.myshopify.com',
    'ApiKey' => 'a07235d5cxx4af2239ea02fe197',
    'SharedSecret' => '7ae8a450xxxx2576cf5e7a606c3',
);

PHPShopify\ShopifySDK::config($config);
$shopify = new PHPShopify\ShopifySDK;

$scopes = array('read_orders','read_script_tags','read_products', 'write_script_tags'); 
$redirectUrl = 'https://xxxx.com/shopify/1/99.php/auth/callback';
$auth = \PHPShopify\AuthHelper::createAuthRequest($scopes, $redirectUrl);

$src = "https://xxxx.com/modules/script72paid.js";

$finalurl='https://xxxxx.myshopify.com/admin/script_tags.json'.


$shopify->ScriptTag->post(array("post"), ''.$finalurl.'', array( "script_tag" => array( "event"=>"onload", "src"=>$src)));

?>

and this is our redirect link code

<?php
require '/home/xxxxxx/public_html/shopify/1/vendor/autoload.php';


$config = array(
    'ShopUrl' => 'xxxx.myshopify.com',
    'ApiKey' => 'a07235d5cxxxxxx9ea02fe197',
    'SharedSecret' => '7ae8a45xxxxxxx76cf5e7a606c3',
);

PHPShopify\ShopifySDK::config($config);
$shopify = new PHPShopify\ShopifySDK;

$accessToken = \PHPShopify\AuthHelper::getAccessToken();

$config2 = array(
'ShopUrl' => 'xxxx.myshopify.com',
'AccessToken' => $accessToken,
);

$shopify2 = new PHPShopify\ShopifySDK($config2);


$src = "https://xxxxx.com/modules/script72paid.js";

$finalurl='https://xxxxx.myshopify.com/admin/script_tags.json'.


$shopify2->ScriptTag->post(array("post"), ''.$finalurl.'', array( "script_tag" => array( "event"=>"onload", "src"=>$src)));

?>

How do we avoid this error with expected Array to be a Hash?

Any help will be great.
