Shopify GraphQL Error "Parse error on " ：\使用 PHP " (COLON) at [2, 35]"

Question

问候我的GraphQL有问题，我不知道如何在不获得的情况下将数据传递到GraphQL

错误消息："在"："(COLON(在[2

以下是我试图传递产品变体id数据并获得一些响应的内容。这是我试图做的事情的示例，以及我对graphql的函数

$variantId = (isset($data->variantId) && !empty($data->variantId)) ? strip_tags($data->variantId) : "";
if(empty($variantId)){
$result['error'] = "Product id not specified!";
}
$query = array("query" => '{
productVariant(id: '. ($variantId) .') {
availableForSale
}
}');
$variants = shopify_gql_call($_SESSION['access_token'], $_SESSION['shop_name'], $query);
if( isset($variants['response']) && !empty($variants['response']) ){
$result[]  = $variants['response'];
}else{
$result['error'] = "Variants not found!";
}
function shopify_gql_call($token, $shop, $query = array()) {
// Build URL
$url = "https://" . $shop . ".myshopify.com" . "/admin/api/".getenv('API_DATE')."/graphql.json";
// Configure cURL
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_HEADER, TRUE);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($curl, CURLOPT_MAXREDIRS, 3);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
// curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 3);
// curl_setopt($curl, CURLOPT_SSLVERSION, 3);
curl_setopt($curl, CURLOPT_USERAGENT, 'My New Shopify App v.1');
curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($curl, CURLOPT_TIMEOUT, 30);
// Setup headers
$request_headers[] = "";
$request_headers[] = "Content-Type: application/json";
if (!is_null($token)) $request_headers[] = "X-Shopify-Access-Token: " . $token;
curl_setopt($curl, CURLOPT_HTTPHEADER, $request_headers);
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($query));
curl_setopt($curl, CURLOPT_POST, true);
// Send request to Shopify and capture any errors
$response = curl_exec($curl);
$error_number = curl_errno($curl);
$error_message = curl_error($curl);
// Close cURL to be nice
curl_close($curl);
// Return an error is cURL has a problem
if ($error_number) {
return $error_message;
} else {
// No error, return Shopify's response by parsing out the body and the headers
$response = preg_split("/rnrn|nn|rr/", $response, 2);
// Convert headers into an array
$headers = array();
$header_data = explode("n",$response[0]);
$headers['status'] = $header_data[0]; // Does not contain a key, have to explicitly set
array_shift($header_data); // Remove status, we've already set it above
foreach($header_data as $part) {
$h = explode(":", $part, 2);
$headers[trim($h[0])] = trim($h[1]);
}
// Return headers and Shopify's response
return array('headers' => $headers, 'response' => $response[1]);
}
}

我强烈建议使用https://packagist.org/packages/shopify/shopify-api而不是实现自己的函数/http请求。

您的查询应该类似于

query anynamehere($id: ID!){
productVariant(id:$id){
availableForSale
}
}

然后将ID作为数组的另一个条目的一部分提交，请检查下面的示例：

$query = [
"query" => 
'query anynamehere($id: ID!){
productVariant(id:$id){
availableForSale
}
}',
"variables"  => [
'id' => $variantId
]
];

您永远不应该将这些值连接为查询字符串的一部分(除非您想处理大量的注入问题(。在此处查看有关变量的更多信息https://graphql.org/learn/queries/
