Graphql API Call /w Query using PHP - php

Question

Struggling to figure out how to make graphql api calls with PHP. I'm trying to use the tezos domain API to convert a .tez domain to an address. My query is working well in their "playground", just can't get this translated to php.
Attempt 1:
$apiUrl = 'https://api.tezos.domains/graphql';
$query = '{
domains(where: { name: { in: "' . $wallet . '" } }) {
items {
address
}
}
}';
$data = #file_get_contents($apiUrl, false, stream_context_create([
'http' => [
'method' => 'POST',
'content' => json_encode(['query' => $query]),
]
]));
$results = json_decode($data, true);
echo $results;
$wallet = $results['data'];
Attempt 2:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://api.tezos.domains/graphql" );
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, '{"query":"{domains(where: {name: { in:"elli0t.tez"}}) {items {address}}}"}');
curl_setopt($ch, CURLOPT_HTTPHEADER,
array(
'Accept-Encoding: gzip, deflate, br',
'Content-Type: application/json',
'Accept: application/json',
'Connection: keep-alive',
'DNT: 1',
'Origin: https://api.tezos.domains' )
);
$result = curl_exec($ch);
print_r($result);
$info = curl_getinfo($ch);
print_r($info);
Attempt 2 at least returns me something.. it says I'm missing a query. Any thoughts?
Here is the curl command generated from the api's playground that appears to work. I'm just having trouble converting this to PHP:
curl 'https://api.tezos.domains/graphql' -H 'Accept-Encoding: gzip, deflate, br' -H 'Content-Type: application/json' -H 'Accept: application/json' -H 'Connection: keep-alive' -H 'DNT: 1' -H 'Origin: https://api.tezos.domains' --data-binary '{"query":"{\n domains(where: { name: { in: \"elli0t.tez\" } }) {\n items {\n address\n }\n }\n}"}' --compressed

Answer 1

From the GraphQL Docs I found this: a basic query with arguments:
{
human(id: "1000") {
name
height
}
}
Whereas your domains query looks like this:
{
domains(where: { name: { in: "' . $wallet . '" } }) {
items {
address
}
}
}
What strikes me as wrong syntax, because you can't find anywhere in the GraphQL Documentation an example for a structure like:
{
domains(where: { ... })
}
I don't know GraphQL, but I would pinpoint it on the colons inside the argument. The only thing I could find where this is allowed is using variables for creating mutations:
mutation CreateReviewForEpisode($ep: Episode!, $review: ReviewInput!)
{
createReview(episode: $ep, review: $review) {
stars
commentary
}
}
So I guess what might be happening that the domain query breakes, or you are chaining your queries together.
I hope this might help you.
