Recently I needed to transform the CURL request into the PHP Curl code, binary data and compressed option having been involved. See the query itself:
curl 'https://terraswap-graph.terra.dev/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://terraswap-graph.terra.dev'
--data-binary '{"query":"{\n pairs {\n pairAddress\n latestLiquidityUST\n token0 {\n tokenAddress\n symbol\n }\n token1 {\n tokenAddress\n symbol\n }\n commissionAPR\n volume24h {\n volumeUST\n }\n }\n}\n"}'
--compressed--binary-data has been implemented as data put in the POST fields, see the following:
curl_setopt($ch_upload, CURLOPT_POSTFIELDS, $post);
--compressed has been implemented as the following:curl_setopt($ch_upload, CURLOPT_ENCODING , "");
See the whole code that works:
$url = "https://terraswap-graph.terra.dev/graphql";
// headers
$headers = ['Content-Type: application/json'
, 'Accept-Encoding: gzip, deflate, br'
, 'Accept: application/json'
, 'Connection: keep-alive'
, 'DNT: 1'
, 'Origin: https://terraswap-graph.terra.dev' ];
// POST payload
$post = '{"query":"{ pairs { pairAddress latestLiquidityUST token0 { tokenAddress symbol } token1 { tokenAddress symbol } commissionAPR volume24h { volumeUST } }}"}';
$timeout = 30;
$ch_upload = curl_init();
curl_setopt($ch_upload, CURLOPT_URL, $url);
curl_setopt($ch_upload, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch_upload, CURLOPT_POST, true);
curl_setopt($ch_upload, CURLOPT_ENCODING , ""); // --compressed
curl_setopt($ch_upload, CURLOPT_POSTFIELDS, $post);
curl_setopt($ch_upload, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch_upload, CURLOPT_CONNECTTIMEOUT, $timeout);
$response = curl_exec($ch_upload);
if (curl_errno($ch_upload)) {
echo 'Curl Error: ' . curl_error($ch);
}
curl_close($ch_upload);
